Answer:

275 ft³

Step-by-step explanation:

Given the ratio of radii of 2 similar figures = a : b , then

ratio of volumes = a³ : b³

Here the ratio of radii = 5 : 2 , so

ratio of volumes = 5³ : 2³ = 125 : 8

Calculate the volume (V) of A using proportion

$\frac{125}{V}$ = $\frac{8}{88}$ = $\frac{1}{11}$ ( cross- multiply )

V = 275 ft³

That is the volume of figure A = 275 ft³

Answer:

7.75

Step-by-step explanation:

(I'm assuming you need to find the missing side of the triangle)

To find missing values in a right angle. we will use the pythagoras theorem which states that:

h^2 = a^2 + b^2

16^2 = 14^2 + b^2

256 = 196 + b^2

256 - 196 = b^2

60 = b^2 (take sqaure root)

b= 7.75

Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items wit

weeeeeb [17]

Answer:

$Change = \$8.82$

Step-by-step explanation:

Given

$Basketball = \$25.57$

$Air\ Pump = \$15.61$

$Amount = \$50$

Required

Determine the change received

First, we need to calculate the total amount spent

$Total = \$25.57 + \$15.61$

$Total = \$41.18$

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

$Change = Amount - Total$

$Change = \$50 - \$41.18$

$Change = \$8.82$

Hence, the change is $8.82

What are the vertical asymptotes of f(x) = 10/ x^2 - 1

Veronika [31]

Vertical asymptotes ares found where the function is undefined. f(x) is undefined when the denominator equals zero:

x^2-1=0

*Add 1 to both sides*

x^2=1

*Take the square root of both sides*

x=+/-1

There are vertical asymptotes at x=-1 and x=1.

Hope this helps!!

How do you solve this if you are solving for y y=3xy-1

Angelina_Jolie [31]

Move all y terms to both sides
subtract both sides by 3xy

y=3xy-1
y - 3xy = -1

factor out y from the left side: y(1 - 3x) = -1
divide both sides by (1-3x)

y = -1/(1-3x)
