Answer:
The rate is 5 dollars per student.
Step-by-step explanation:
The rate per student can be found with [tex]\frac{dollars}{student}[/tex]:
[tex]\frac{150dollars}{30student}=5\frac{dollars}{student}\\\\\frac{350dollars}{70student}=5\frac{dollars}{student}[/tex]
The rate is 5 dollars per student.
Unit rates can be helpful with creating a ratio table and plotting the equivalent ratios on a coordinate plane. Explain why. PLEASE ANSWER ASAP AND PLEASE GIVE ME THE ANSWER!!!
Answer:
Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.

The similarity ratio of two similar triangles is equal to the ratio of their corresponding sides :
Similarity ratio = BA / GF = BC / GH = CA / HF
Similarity ratio = 18 / 9 = 14 / 7 = x / 6
x / 6 = 2
multiple sides by 6
6 × x / 6 = 6 × 2
simplification
x = 12

Point L is located at (-3,-6) where is L after a reflection over the y-axis
9514 1404 393
Answer:
L'(3, -6)
Step-by-step explanation:
The reflection over the y-axis is modeled by the transformation ...
(x, y) ⇒ (-x, y)
L(-3, -6) ⇒ L'(3, -6)
Point L is located at (3, -6) after the reflection from the 3rd quadrant to the 4th quadrant across the y-axis.

You walk into a store that is closing. The pants normally cost $60.00 but it is discounted 75%. They are also taking an additional 20% off. What is the final price that you pay for the pants? dollars and cents. For example 19 dollars and 25 cents would be written as $19.25
Answer:
The final cost that I will pay for the pants is $ 12.
Step-by-step explanation:
Since I walk into a store that is closing, and the pants normally cost $ 60.00 but it is discounted 75%, and they are also taking an additional 20% off, to determine what is the final price that I will pay for the pants se must perform the following mathematical calculation:
100 - 20 = 80
(60 - (60 x 0.75)) x 0.80 = X
(60 - 45) x 0.80 = X
15 x 0.80 = X
12 = X
So, the final cost that I will pay for the pants is $ 12.
what is the value of A when we rewrite (32/5)^-2x as A^x
Answer:
[tex](\dfrac{25}{1024})^x[/tex]
Step-by-step explanation:
The given expression is :
[tex](\dfrac{32}{5})^{-2x}[/tex]
We need to rewrite it in the form of [tex]A^x[/tex].
We know that, [tex](\dfrac{1}{x})^{-a}=x^a[/tex]
So,
[tex](\dfrac{32}{5})^{-2x}=(\dfrac{5}{32})^{2x}\\\\=(\dfrac{5^2}{32^2})^x\\\\=(\dfrac{25}{1024})^x[/tex]
So, [tex]A=\dfrac{25}{1024}[/tex]. Hence, this is the required solution.
Answer: A = (32/5)^-2

Kyle fills the candle mold with liquid candle wax. If
the candle has a volume of 99 cubic inches, what is the
width of the mold?
Answer:
w = 3 inches
Step-by-step explanation:
Given that,
The volume of the candle, V = 99 cubic inches
Length, l = 11 inches
Breadth, b = 3 inches
We need to find the width of the candle. The candle is in the form of a cuboid. The volume of cuboidal shape is given by :
[tex]V=lwh[/tex]
Put all the values,
[tex]w=\dfrac{V}{lb}\\\\w=\dfrac{99}{11\times 3}\\\\w=3\ inches[/tex]
So, the width of the mold is 3 inches.

If a $6.00 ball was bought for $5.25, what was the percentage of the discount?
A. 25%
B. 12.5%
C. 15%
D. 20%
E. 75%
Please show work and I will make brainlist.
Answer:
B
Step-by-step explanation:
x% of 6 = 5.25
[tex]\frac{x}{100}[/tex] x 6 = 5.25
[tex]\frac{(5.25)(100)}{6}[/tex] = x
x = 87.5 %
discount = 100 - 87.5 %
= 12.5 %
