Alex bought 4 hoodies. Each hoodie cost the same amount and they were on sale for $5 off each. Alex paid a total of $120. How mu
vladimir2022 [97]
Total price equals 4 hoodies times (original price minus $5).

x= original hoodie price

$120= 4(x-5)
Use distributive property to multiply
120=(4*x) - (4*5)
120= 4x - 20
Add 20 to both sides
140=4x
Divide both sides by 4
$35= x

Original hoodie price was $35.

Hope this helps! :)

Electric utility poles in the form of right cylinders are made out of wood that costs $25.46 per cubic foot. Calculate the cost
kotegsom [21]

Answer:

$ 1349.746624

Step-by-step explanation:

The volume of a cylinder

The formula for calculating the volume of a cylinder is expressed as:

V=πr²h

where:

r is the radius

h is the height

Given the following parameters

r = d/2 = 1.5/2 = 0.75ft

h = 30ft

Get the volume of the cylinder

V=π(0.75)²(30)

V= 53.0144...ft³

If the wod costs $25.46 per cubic foot, hence the cost of the wood will be 53.0144*25.46 = $ 1349.746624
