Answer: y - 0.18y
Step-by-step explanation:
From the question, Emerson practice a game that was on sale for 18% off the sales tax in his country.
Let y represent the original price of the game. The be used to determine the final cost of the game will be:
We have to subtract the 18% discount from the original price to get the final cost of the game. This will be:
= y - (18% of y)
= y - (18/100 × y)
= y - (0.18 × y)
= y - 0.18y
The final expression is y-0.18y
Answer:
45 and 45
Step-by-step explanation:
Short answer: r = 8
Remark
The easiest way to do this is to solve the sphere's volume in terms of pi. When you do this, you can equate that to the formula for a cylinder and cancel the pi values.
Step One
Find the volume of the sphere.
<em>Givens</em>
r = 6 cm
<em>Formula</em>
V = (4/3) pi r^3
<em>Sub and Solve</em>
V = 4/3 pi * 6^3
V = 288 * pi
Step two
Find the radius of the cylinder
<em>Givens</em>
V = 288* pi cm^3
h = 4.5 cm
<em>Formula</em>
V = pi r^h
<em>Sub and solve</em>
288 pi cm^3 = pi r^2 * 4.5 Divide both sides by pi
288 cm^3 = 4.5 r^2 Divide both sides by 4.5
388 / 4.5 = r^2
64 = r^2 Take the square root of both sides.
r = square root( 64)
r = 8 <<<<< Answer
8kg, Because 8kg in oz is 282
