To determine the amount of gold plating necessary for the similar box, you will use the fact that it is 8 times larger in volume to determine how many times larger the area is. This would be what you will multiply $125 by.
Volume is a three dimensional measurement, so the fact that it is 8 times larger tells us each dimension was 2 times larger (2 x 2 x 2=8).
Area is a two dimensional measurement, so the area would have been 2 x 2 or 4 times larger. This means the price would be 4 times as much.
$125 x 4 = $500.
It will cost $500 to gold plate the similar jewelry box.
Answer: .7(b)
Step-by-step explanation:
.7(b)
If (a, b) is on the graph of a function f(x), then (b, a) is on the graph of the inverse.
We have points on the graph of a function: {(-3, 9), (-1, 1), (0, 0), (2, 4)}.
The points on the graph of the inverse: {(9, -3), (1, -1), (0, 0), (4, 2)}.
<h3>Answer: (4, 2), (0, 0), (1, -1).</h3>
63/3= 21
So 21 miles per gallon of gas
To find 7, you multiply it by 7
21*7= 147
147 miles on 7 gallons of gas
