Answer:
Step-by-step explanation:
Area = side*side
side * side = 49
side * side = 7*7
side = 7 inches
Perimeter = 4*side
=4 * 7
= 28 inches
Answer:
Step-by-step explanation:
Data:
V₁ = 125 in³
V₂ = 729 in³
Calculations:
A scale factor (C) is the ratio of corresponding side lengths (l) of the two prisms.
The volume ratio is the cube of the scale factor.
![C = \sqrt [3]{\frac{ 125}{729 }} = \frac{5 }{9 }\\](https://tex.z-dn.net/?f=C%20%3D%20%5Csqrt%20%5B3%5D%7B%5Cfrac%7B%20125%7D%7B729%20%7D%7D%20%3D%20%5Cfrac%7B5%20%7D%7B9%20%7D%5C%5C)
Each friend spent $50 (50+50+50= 150)
Sarah spent twice as much as them150*2=300
altogether they spent $150+$300= $450

Answer:
35/6
Step-by-step explanation:
We have, 140:24
Dividing by 4 we get 35:6
As there is no other common factor to divide with, 35:6 is the simplest form.
Answer:
the length and width . Round to the nearest tenth are 8.8 inches and 3.8 inches respectively.
Step-by-step explanation:
The area A of a rectangle is the product of the length L and width W. This may be expressed mathematically as
A = L * W
As such, given that the length is 5 inches more than the width,
L = W + 5
33 = W(W + 5)
W² + 5W - 33 = 0
Using the formula method which states that
s = -b±√(b²-4ac)/2a
W = -5 ± √5² - 4(1)(-33)/2
= -5 ± 12.53/2
= 7.53/2 (since length cannot be negative)
= 3.755 inches
L = 3.755 + 5
= 8.755 inches
