Step-by-step explanation:

plug in x and y into the equation

Answer:

Cold length 7 days or longer with medicine taken = 0.24

Cold length less than 7 days with medicine taken = 0.76

Cold length 7 days or longer without medicine taken = 0.69

Cold length less than 7 days without medicine taken = 0.31

Perimeter and height are in inches and area is inches squared

Answer:

  (d)  x = -3/4; y = -3 1/2

Step-by-step explanation:

You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.

The idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.

In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.

horizontal coordinate

The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.

  x = -3/4

vertical coordinate

The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.

  y = -3 1/2

Answer:

1/2

it would be less because rt42 is closer to halfway between 6 and 7

Answer:

Less that

Step-by-step explanation:

rt42 is closer to halfway between 6 and 7

Answer:

C (√34)

Step-by-step explanation:

Pythagoras' theorem states that: a² + b² = c², where c is the hypotenuse and what we are trying to figure out.

So, 3² + 5² = c²

9 + 25 = 34 = c²

c = √34

Answer:

C (√34)

Step-by-step explanation:

Answer: B. None

Step-by-step explanation:

The best way to figure this out is by graphing it. I used Desmos graphing calculator. The red line is the first equation, and the blue line is the second one. As you see, they do not intersect anywhere, therefore will not have any solutions.

I hope this helps!! Pls mark brainliest!! :)

Answer:

3  * 3/4 =

9/4 or 2.25

Answer:

b 4 + 3p ≥ 40

Step-by-step explanation:

he needs more than 40 points, so we need to pick and answer with a greater than or equal to sign that faces the side with Glenn's points. This leaves b or c for our answers. Glenn played 3 different rounds in which he scored a value represented by the variable p. Additionally, he scored a value of 4 points is given. Therefore, because he scored p in 3 different rounds, p is multiplied by 3 to make 3p. So, 4+3p≥ 40 (answer b) is correct

Answer:

b 4 + 3p ≥ 40

Step-by-step explanation:

Answer:

D. 11n + 12

Step-by-step explanation:

You can simplify the 4n + 7n to be 11n by adding them together.

This means the answer is 11n + 12.

Answer:

Flase

Step-by-step explanation:

Solid a has a surface area of 170 sq ft.

Solid b has a surface area of 126 sq ft.

Just knowing this information we already know that the statement is false

Answer:

False

Step-by-step explanation:

1. Find the surface area

          Shape 1                                Shape 2

(4 x 5)2 + (5x5)4 = 140        (6 x 3)2 + (3 x 5)2 + (6 x 5)2 = 126

2. Exclude the bases

          Shape 1                                Shape 2

    140 - 40 = 100                        126 - 36 = 90

All in all, this is FALSE

Hope this helped. Please give brainliest. It took me a long time (30 minutes).

Answer:

  D.  8/7

Step-by-step explanation:

A probability value is always in the interval [0, 1], between 0 (can't happen) and 1 (certain to happen).

__

A value of 8/7 will not be a probability. Statement D does not correctly use probability.

Step-by-step explanation:

Multiply

2.21 by 5.1

Answer:

You divide both the numerator and the denominator by the same number until they can't be reduced any further.

Answer:

Make sure to divide the upper number and the lower number (in position) to a number which can't be futher divided. It will be of numbers which are really small numbers. like 4/2 will be divided by 2 to get the simplified answer of 1/2

Step-by-step explanation:

This program simplifies our complex monetary system by familiarizing users with common combinations of coins and bills that are equivalent in value. Starting with five pennies equal one nickel, the program works up to equivalents for a twenty dollar bill.

Answer:

$1.05

Step-by-step explanation:

1 dime = 10 cents so 7 dimes = 70 cents
1 quarter = 25 cents

Therefore 10 cents + 7 dimes + 1 quarter = 10 + 70 + 25 = 105 cents = $1.05

1 month is aprox. 30 days, so

To find john's daily salary:

For a month, the salary is 4,410 rupees, so for a day how much?

days     salary

30          4,410    (This is how I learnt to solve these kind of problems)

1               ?

Then you crisscross the equation which becomes

4,410/30=147 rupees

To find weekly salary:

we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?

You multiply the salary for one day and the number of days: 147×7=1,029 rupees

To find salary for a year (annual):

we now know the salary for one day so we can say:  For a day, the salary is 147 rupees, so for 365 days (1 year) how much?

You multiply the salary for one day and the number of days: 147×365=53,655 rupees

Hope it helps!

Answer: C

Step-by-step explanation:

Step 1: Find the unit rate (tomatoes  per  bowl)

Last time, the ratio was 9:12, or 9 tomatoes for 12 bowls of soup. To finndd the unit ratet, dividde the ffirst given unnit by the 2nd. In this case, tomatoes is the first unit, and bowls is the second. So the unit rate is:

9÷12= 0.75, or 3/4 of a tomato  per bowl of soup.

Now, the  ratio is 6:8, or 6 tomatoes for 8 bowls of soup. The unit rate is

6÷8= 0.75, or 3/4of a tomato per bowl of soup.

Step 2: Compare

As you can see, the number of tomatoes per bowl of soup hasn't changed at all. So the answer is C.

Hope this helps :)

Answer:

Todays’s soup will taste the same.

Step-by-step explanation:

9 tomatoes for every 12 cups of soup- ratio= 9/12=3/4

6 tomatoes for every 8 cups of soup- ratio=6/8=3/4

They both end in the same ratio, which is 3/4.

the question isn't possible to answer because 9 is not divisible by 6

Answer:

  It is not possible to make 4_9 divisible by 6

Step-by-step explanation:

A number that is divisible by 6 will be divisible by 2 and by 3. An integer is divisible by 2 if its units digit is even. An integer is divisible by 3 if the sum of its digits is divisible by 3.

__

The given number has a units digit of 9, which is not even. The number cannot be made divisible by 2 for any inserted digit.

It is not possible to make 4_9 divisible by 6.

Answer:

The answer is no because for 1 hour he gets 20 dollars and for 2 hours he gets 30$ (which is less for working 2 hours). So, if you multiply 2 hours with 20 dollars, you should get 40, not 30. So therefore, it is not proportional. And same for 3 hours: multiply 3 with 20 to get 60, not 50.
