Liquid a has a density of 1.2 g/cm'
150 cm of liquid a is mixed with some of liquid b to make liquid c.
liquid c has a mass of 220 g and a density of 1.1 g/cm
find the density of liquid b.

Answers

Answer 1

Density of liquid b = 0.4 g/cm³.

How to find the density of liquid B?Density of liquid A = 1.2 g/cm³Volume of liquid A = 150 cm³Mass of liquid C = 220 gDensity of liquid C = 1.1 g/cm³

Let the volume of liquid B added be V cm³.

The total volume of the mixture = Volume of A + Volume of B = 150 + V cm³

Using the formula:

Density = Mass/Volume

Density of C = (Mass of C) / (Volume of C)

1.1 = 220 / (150 + V)

Solving for V, we get:

V = 100 cm³

Therefore, the volume of liquid B added is 100 cm³.

The total mass of the mixture = Mass of A + Mass of B = (Density of A x Volume of A) + (Density of B x Volume of B)

220 = (1.2 x 150) + (Density of B x 100)

Solving for Density of B, we get:

Density of B = (220 - 180) / 100 = 0.4 g/cm³

Therefore, the density of liquid B is 0.4 g/cm³.

of an hour. if he continues reading at the same rate, how many pages will he read in an hour?

Answers

Daniel will read approximately 193 pages in one hour if he continues reading at the same rate.

How many pages will Daniel read in an hour?

Since Daniel read 77 pages in $\frac{2}{5}$ of an hour, we can set up the proportion:

$\frac{77}{\frac{2}{5}} = x$

where $x$ is the number of pages he would read in 1 hour.

To solve for $x$, we can simplify the left side of the equation by multiplying both the numerator and denominator by 5, which gives:

$\frac{77 \times 5}{2} = x$

Simplifying this expression gives:

$192.5 = x$

Therefore, if Daniel continues reading at the same rate, he will read 192.5 pages in one hour. However, since the number of pages must be a whole number, we can round this answer to the nearest whole number to get:

$x \approx 193$

So, Daniel will read approximately 193 pages in one hour if he continues reading at the same rate.

A single number cube is rolled twice. The 36​ equally-likely outcomes are shown to the right. What is the first step in finding the probability of getting two numbers whose sum is 12​? Find the probability of getting two numbers whose sum is 12.

Answers

The probability of getting two numbers whose sum is 12 when rolling a single number cube twice is 1/36.

To find the probability of getting two numbers whose sum is 12 when a single number cube is rolled twice, we'll first need to identify the favorable outcomes.

A number cube has six faces, numbered from 1 to 6. When it is rolled twice, there are 6 x 6 = 36 equally-likely outcomes. To find the probability, we can use the formula:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

The first step is to identify the favorable outcomes, which are the pairs of numbers that add up to 12. Since we are dealing with a number cube that has faces numbered 1 to 6, there is only one possible pair that satisfies this condition: (6,6).

Now that we have determined the favorable outcome, we can find the probability:

Probability = (Number of favorable outcomes) / (Total number of outcomes)
Probability = 1 (for the pair 6,6) / 36

Thus, the probability of getting two numbers whose sum is 12 when rolling a single number cube twice is 1/36.

The mean number of days with 0. 01 inch or more precipitation per month for Lewiston, Idaho, is about 8. 7. Find the probability that in a given month


(a) There are exactly 9 days with 0. 01 inch or more precipitation.


(b) There are at most 9 days with 0. 01 inch or more of precipitation.


(c) There are more than 9 days with 0. 01 inch or more of precipitation

Answers

We will use the Poisson distribution, which is a probability distribution that models the number of events occurring in a fixed interval of time or space, given the average rate of occurrence and assuming that the events are independent and randomly distributed.

For this problem, we will assume that the number of days with 0.01 inch or more precipitation in Lewiston, Idaho, follows a Poisson distribution with parameter λ = 8.7.

(a) To find the probability that there are exactly 9 days with 0.01 inch or more precipitation, we can use the Poisson probability mass function:

P(X = k) = e^(-λ) * λ^k / k!

where X is the random variable representing the number of days with 0.01 inch or more precipitation, λ is the parameter of the Poisson distribution, and k is the number of events we are interested in.

Plugging in the values, we get:

P(X = 9) = e^(-8.7) * 8.7^9 / 9! ≈ 0.151

Therefore, the probability that there are exactly 9 days with 0.01 inch or more precipitation is approximately 0.151.

(b) To find the probability that there are at most 9 days with 0.01 inch or more precipitation, we can use the cumulative distribution function of the Poisson distribution:

P(X ≤ k) = ∑i=0^k e^(-λ) * λ^i / i!

Plugging in the values, we get:

P(X ≤ 9) = ∑i=0^9 e^(-8.7) * 8.7^i / i! ≈ 0.503

Therefore, the probability that there are at most 9 days with 0.01 inch or more precipitation is approximately 0.503.

(c) To find the probability that there are more than 9 days with 0.01 inch or more precipitation, we can subtract the probability of having 9 or fewer days from 1:

P(X > 9) = 1 - P(X ≤ 9) ≈ 0.497

Therefore, the probability that there are more than 9 days with 0.01 inch or more precipitation is approximately 0.497.

A hardware store carries 42 types of boxed nails and 36 types of boxed screws. the store manager wants to build a rack so that he can display the hardware in rows. he wants to put the same number of boxes in each row, but he wants no row to contain both nails and screws. what is the greatest number of boxes that he can display in one row? how many rows will there be if the manager puts the greatest number of boxes in each row?

Answers

There will be a total of 7 rows for nails and 6 rows for screws, making 13 rows in total.

To solve it, we need to find the greatest common divisor (GCD) of the number of boxed nails (42) and boxed screws (36). This will tell us the greatest number of boxes that can be displayed in one row without mixing nails and screws.

Step 1: List the factors of each number.
- Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
- Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

Step 2: Find the greatest common divisor (GCD) by identifying the largest factor they have in common.
- The largest common factor is 6.

So, the greatest number of boxes that can be displayed in one row is 6.

Next, we'll find out how many rows will there be if the manager puts the greatest number of boxes in each row.

Step 3: Divide the total number of boxed nails and boxed screws by the GCD.
- Rows for nails: 42 ÷ 6 = 7
- Rows for screws: 36 ÷ 6 = 6

Therefore, there will be a total of 7 rows for nails and 6 rows for screws, making 13 rows in total.

A new laptop is on sale for $550 dollars. To pay for it you place it on your credit card which charges 12% percent interest each month. Complete the table to determine the total cost of the laptop each month if you make no payments

Answers

To determine the total cost of the laptop each month if you make no payments, we need to calculate the balance on the credit card after each month, including the simple interest charged.

Starting balance = $550

Month Balance Interest Total Cost
0 $550 $0 $550
1 $616 $66 $616 + $66 = $682
2 $689.92 $73.92 $689.92 + $73.92 = $763.84
3 $770.15 $80.23 $770.15 + $80.23 = $850.38
4 $857.09 $86.94 $857.09 + $86.94 = $944.03
5 $951.19 $94.10 $951.19 + $94.10 = $1045.29


To calculate the balance for each month, we multiply the previous balance by 1.12, which represents the 12% interest charged. For example, for month 1, the balance is $550 * 1.12 = $616.

To calculate the interest charged each month, we subtract the previous balance from the new balance. For example, for month 1, the interest charged is $616 - $550 = $66.

To calculate the total cost each month, we add the new balance to the interest charged.

For example, for month 1, the total cost is $616 + $66 = $682.

Note that if you make no payments on the credit card, the balance will continue to grow each month due to the interest charged.

It is always advisable to make at least the minimum payment each month to avoid high interest charges and potential late fees.

The y-values that a function approaches when the x-values are extremely large or extremely small. this is called the function's ____ behavior.

Answers

The y-values that a function approaches when the x-values are extremely large or extremely small is called the function's asymptotic behavior.

When we talk about the asymptotic behavior of a function, we are referring to what happens to the values of the function as the input (x-values) either tends to positive infinity or negative infinity.

In other words, we are interested in how the function behaves when the input values become extremely large or extremely small.

To understand asymptotic behavior, let's consider two types of asymptotes: horizontal and vertical asymptotes.

Horizontal Asymptotes:

A horizontal asymptote is a horizontal line that a function approaches as the x-values become extremely large or extremely small. We usually denote horizontal asymptotes as y = c, where c is a constant.

For example, let's consider the function f(x) = (2x^2 + 3) / (x^2 - 1). As x approaches positive or negative infinity, we can observe the following behavior:

As x becomes extremely large or extremely small, the function becomes closer and closer to the line y = 2. Therefore, we say that y = 2 is a horizontal asymptote for this function.

Vertical Asymptotes:

A vertical asymptote is a vertical line that the function approaches as the x-values approach a particular value. It typically occurs when there is a division by zero or when the function tends to infinity at a specific point.

For example, consider the function g(x) = 1 / (x - 2). As x approaches 2 from either side (but never equal to 2), we can observe the following behavior:

As x approaches 2 from the left (x < 2), the function g(x) becomes increasingly negative, tending towards negative infinity.

As x approaches 2 from the right (x > 2), the function g(x) becomes increasingly positive, tending towards positive infinity.

In a recent report, Joe's, a Memphis-style barbecue chain, states that 11% of its customers order for delivery. A random sample of 6 Joe's customers is chosen. Find the probability that at most 1 of them order for delivery. " Do not round your intermediate computations, and round your answer to three decimal places.

Answers

P(X ≤ 1) = P(X = 0) + P(X = 1) ≈ 0.901

So the probability that at most 1 customer in the sample orders for delivery is approximately 0.901, rounded to three decimal places.

To solve this problem, we can use the binomial distribution since we have a fixed number of trials (6) and each trial can result in one of two outcomes (ordering for delivery or not).

Let X be the number of customers in the sample who order for delivery. Then X follows a binomial distribution with parameters n = 6 and p = 0.11 (the probability of ordering for delivery).

We want to find the probability that at most 1 customer orders for delivery. This can be written as:

P(X ≤ 1) = P(X = 0) + P(X = 1)

To calculate these probabilities, we can use the binomial probability formula:

P(X = k) = (n choose k) *[tex]p^k[/tex]*[tex](1 - p)^(n - k)[/tex]

where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n distinct items.

Using this formula, we can calculate:

P(X = 0) = (6 choose 0) * 0.11^0 * [tex]0.89^6[/tex] ≈ 0.530

P(X = 1) = (6 choose 1) * 0.11^1 * 0.89^5 ≈ 0.371

y = 13k

where "k" is a constant that we need to find.

Substituting these expressions for x and y into the equation, we get:

10 + 4k + 13k = 180

17k = 170

k = 10

Now we can find the values of x and y:

x = 4k = 4(10) = 40

y = 13k = 13(10) = 130

Therefore, the measures of the two angles in the ratio of 4:13 are 40 degrees and 130 degrees, respectively.

70% of a class is at lunch what percentage is still studying?​

Answers

Answer:

30%

Step-by-step explanation:

21. Marla is drawing a regular polygon. She has drawn two of the sides with an interior angle of 140°, as shown below. When Marla completes the regular polygon, what should be the sum, in degrees, of the measures of the interior angles?

Answers

The sum of the measures of the interior angles is 1260 degrees

What should be the sum of the measures of the interior angles?

From the question, we have the following parameters that can be used in our computation:

An interior angle = 140 degrees

The sum of interior angles of a regular polygon is:

S = (n - 2) × 180

Where n is the number of sides of a polygon

Also, we have

S = 140n

Substitute the known values in the above equation, so, we have the following representation

140n = (n - 2) × 180

Expand

140n = 180n - 360

This gives

40n = 360

Divide

n = 9

Recall that

S = (n - 2) × 180

So, we have

S = (9 - 2) × 180

Evaluate

S = 1260

Hence, the sum of the measures of the interior angles is 1260 degrees

Simon bought a 10-pound bag of cat food. he give 0.3 pounds of food per day. write an equation in two variables to describe how the amount of cat food in the bag changes over time. explain variable in your equation represent

Answers

The equation in two variables that describes how the amount of cat food in the bag changes over time is: A = 10 - 0.3t
Where A represents the amount of cat food left in the bag after t days, and t represents the number of days that have passed since Simon bought the bag.

The variable A is the dependent variable because it depends on the value of t. As time passes and t increases, the amount of cat food left in the bag decreases. The variable t is the independent variable because it is the input that determines the value of A.

For example, after one day (t = 1), Simon will have used 0.3 pounds of cat food and there will be 9.7 pounds left in the bag (A = 10 - 0.3(1) = 9.7). After two days (t = 2), he will have used 0.6 pounds of cat food and there will be 9.4 pounds left in the bag (A = 10 - 0.3(2) = 9.4), and so on.

The desert wind blew harshly towards her direction as grains of sand grazed against her face. Sweat trickled down her arm nervously. It travels slowly down her hand to her bruised knuckles before dripping to the ground beneath. She stood still like a prey in front of a predator. With one foot in front of the other and her back bending slightly forward; preparing to sprint.And now, the moment that all of you have been waiting for.. , a deep voice echoed throughout the arena, sending vibrations down everyones chest.She grinded her feet deeper into the patchy ground. Though 10 feet apart, Melissa can hear her opponents long and sharp breathing, almost as if it is already trying to rip her apart. A life or death situation, this is. One will stay, and one must go. For Melissa, it will be either glory, or death. BOOM!There it was, the sound of the gunshot. It rang through Melissas ears like church bells, but she was quick to react. She pointed her body towards the left side of the arena and started to sprint like a bull. By the time she got there, her opponent was already behind her. No doubt, her opponent is not one to be messed with. However, Melissa was prepared. She waited for the perfect moment to strike, her legs bent and her back arched. The opponent was towering over her, but she showed not a hint of fear. Melissa swung her hand at them. A puff of hot sand hit their face and entered their eyes. It was a sly move, to say the most. But it did the job. With no time left to spare, she picked up a sharp rock beside her and aimed it at the opponent, who was on the ground with tears rolling down their face. Just before she was able to throw the rock, she felt a piercing sensation. Drip.The dripping accelerated. Melissa placed her hand on the ground as she crouched on the dusty ground. Coughing as she breathed in little sand particles. Her pupils dilated. Hesitantly, she lowered her head and shifted her eyes to her wound; an arrow was sticking out her stomach.
