Help need to do it the equation and the real world problem

melomori [17]

A volleyball uniform costs $13 for the shirt, $11 for pants, and $8 for socks. Write two equivalent expressions for the total cost of 12 uniforms. Then find the cost.

Write an expression for the cost of 1 uniform, add $13, $11 and $8 .

$13+$11+$8

Write an expression for the cost of 12 uniforms, multiply 12 by the cost of 1 uniform.

12($13+$11+$8)

Simplify using the distributive property.

=12⋅13+12⋅11+12⋅8=156+132+96

Now Add.

=384

So, the total cost of 12 uniforms is $384 .

Based on surveys, 97% of students own cell phones. What is the probability that 10 randomly selected

yarga [219]

Answer:

$Probability = 0.7374$

Step-by-step explanation:

Given

Represent the probability that a student has a phone with p

$p = 97\%$

Required

Determine the probability that 10 has

This is calculated as thus:

$Probability = p^n$

Where n = 10

$Probability = (97\%)^{10}$

$Probability = 0.97^{10}$

$Probability = 0.73742412689$

$Probability = 0.7374$ --- Approximated

a cd player that regularly sells for 240 is on sale at 40 % discount how much will Mariah save off the price if she buys the CD

cupoosta [38]

Okay so if it is 40% off then we will be left with 60% so our decimal multiplier is 0.6
we times 240 by 0.6 to get 144 which is our answer

Need help with finding answer

inysia [295]

Answer: 2520 cm³

Step-by-step explanation:

1. You must use the following formula for calculate the volume of a triangular pyramid, which is:

$V=\frac{B*h}{3}$

Where B is the area of the base and h is the height.

2. Calculate the area of the triangular base:

$B=\frac{24cm*18cm}{2}\\B=216cm^{2}$

3. Susbstiute values into the formula for calculate the volume. Then, you obtain the following result:

$V=\frac{216cm^{2}*35cm}{3}=2520cm^{3}$
