The cost to mail a package varies directly to the weight of the package. If a 14- ounce package costs $4.48 to mail, find the weight of a package that cost $8 to mail.
Answer:
Step-by-step explanation:
Ok so first, we must figure out what 1 once costs. This can be done by divideing 4.48(cost) by 14(weight).
You should get 0.32.
Now just multiply by 8 and you should get your answer. This answer is 2.56.
Answer:
2.56
Another way this can be done is dividing 8(second weight) by 14(first weight) which will get you the difference. This is 0.5714 blah blah blah goes on for a long time. Now, take this number and multiply it by the 4.48(first cost). This should get you 2.56.
Answer:
2.56

A cone has radius 3.8 cm and height 7.6 cm. The radius and the height are doubled. Which of the following describes the effect on the volume?
Answer:
The volume is multiplied by 8.
Step-by-step explanation:
The volume of a cone with a radius of 3.8 and a height of 7.6 is 114.92. Now let’s double them, the results come out to be 919.39, we divide these by each other and we get roughly 8 when you round. Therefore, your answer is 8.
On a multiple-choice test, a student has four possible choices for each question. The student receives 1 point for a correct answer and loses ¼ point for an incorrect answer. If the student has no idea of the correct answer for a particular question and merely guesses, what is the student's expected gain or loss on the question? Suppose you were using an
Answer:
1 / 16
Step-by-step explanation:
Number of options = 4
Number of correct answers = 1
Number points gained for a correct answer = 1
Number of points lost for an incorrect answer = 1/4 = 0.25
Probability of choosing a correct option = 1/4
Probability of choosing an incorrect option = 3/4
x ____ 1 ______ - 1/4
P(x) __ 1/4 ______ 3/4
Expected gain or loss :
E(x) = Σx*p(x)
E(x) = (1 * 1/4) + (-1/4 * 3/4)
E(x) = 1/4 - 3/16
E(x) = (4 - 3) / 16
E(x) = 1 /16
A gain of 1/16

Justin found that his text-messages contain 5 emoji for every 15 regular characters. How many emoji will Justin use if his text message contains 100 total characters ?
Answer:
Justin will use 300 emojis.
Step-by-step explanation:
15/5=3
So, 3 emoji for one regular character.
3*100= 300.
Answer:
33 emojis
Step-by-step explanation:
5 emojis = 15 characters
1 emoji = 15 ÷ 5 = 3 characters
100 ÷ 3 = 33.3
33.3 estimated to nearest whole number = 33

Dr. Baker, a veterinarian, recorded the weight of each newborn kitten her office saw today.
Kittens' weights (g)

Answer:
30 grams is the answer
As per the given data, the interquartile range of the kittens' weights is 60 g.
What is interquartile range?The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles.
The IQR is the range between the first quartile (Q1) and the third quartile (Q3). It represents the range of the middle 50% of the data set.
To find the interquartile range (IQR) of the kittens' weights, we need to first find the median and the quartiles.
Find the median (Q2):
The median is the middle value when the data is arranged in order. In this case, we have an even number of data points, so we take the average of the two middle values:
100, 120, 140, 160, 180, 200
The middle values are 140 and 160, so the median is:
(Q2) = (140 + 160) / 2 = 150
Find the first quartile (Q1):
The first quartile is the middle value of the lower half of the data. To find Q1, we take the median of the lower half:
100, 120, 140
The median is 120, so Q1 is:
Q1 = 120
Find the third quartile (Q3):
The third quartile is the middle value of the upper half of the data. To find Q3, we take the median of the upper half:
160, 180, 200
The median is 180, so Q3 is:
Q3 = 180
Calculate the interquartile range:
The interquartile range is the difference between the third and first quartiles:
IQR = Q3 - Q1 = 180 - 120 = 60
Therefore, the interquartile range of the kittens' weights is 60 g.

Write the square roots of 49 i in ascending order of the angle.
Answer:
The square roots of 49·i in ascending order are;
1) -7·(cos(45°) + i·sin(45°))
2) 7·(cos(45°) + i·sin(45°))
Step-by-step explanation:
The square root of complex numbers 49·i is found as follows;
x + y·i = r·(cosθ + i·sinθ)
Where;
r = √(x² + y²)
θ = arctan(y/x)
Therefore;
49·i = 0 + 49·i
Therefore, we have;
r = √(0² + 49²) = 49
θ = arctan(49/0) → 90°
Therefore, we have;
49·i = 49·(cos(90°) + i·sin(90°)
By De Moivre's formula, we have;
[tex]r \cdot (cos(\theta) + i \cdot sin(\theta) )^{\dfrac{1}{2}} = \pm \sqrt{r} \cdot \left (cos\left (\dfrac{\theta}{2} \right ) + i \cdot sin\left (\dfrac{\theta}{2} \right ) \right )[/tex]
Therefore;
√(49·i) = √(49·(cos(90°) + i·sin(90°)) = ± √49·(cos(90°/2) + i·sin(90°/2))
∴ √(49·i) = ± √49·(cos(90°/2) + i·sin(90°/2)) = ± 7·(cos(45°) + i·sin(45°))
√(49·i) = ± 7·(cos(45°) + i·sin(45°))
The square roots of 49·i in ascending order are;
√(49·i) = - 7·(cos(45°) + i·sin(45°)) and 7·(cos(45°) + i·sin(45°))
graph 3x+6y=18 In the box below, enter the y value when x = 2.
Answer:
y = 2
Step-by-step explanation:
3x + 6y = 18
3(2) + 6y = 18
6 + 6y = 18
Since 18 - 6 = 12, y will equal 2.
6 + 6(2) = 18
6 + 12 = 18
The coordinates to graph the equation would be (2, 2).

Is (6, 1) a solution to the inequality 11x + 3y > 4?
Answer:
Yes (6,1) is a solution to the inequality
Step-by-step explanation:
Plug in the coordinate point and check:
11(6)+3(1)>4?
66+3>4?
69>4
Since 69 is indeed greater than 4, then (6,1) is a solution to the inequality.

A table is shaped like a regular hexagon. The length of one side is (7x + 4) in. and the length of another side is (8x − 1) in. Find the length of a side.
The length of a side of the table is
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.
