Answer:
x = 20
Step-by-step explanation:
Exterior angles are equal.
7x - 3 = 6x + 17
Add 3 and subtract 6x to both sides.
x = 20 is the answer.
18.70
Because they are 1.10 each
Answer:
G. 25%
Step-by-step explanation:
given : The price of a video game was reduced from $60 to $45 .
$60 - $45 = $15
then, the percentage was the price of the video game reduced :-
reduction in price/previous price x 100 = 15/60 x 100 = 25%
the percentage was the price of the video game reduced = 25%
The first thing we must do for this case is to find the scale factor based on the dimensions of the figures.
The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter than the next larger figure.
We have then that the smallest figure has a height of 1 inch.
The scale factor is:
k = (smallest figure) / (largest figure) = 1/7
k = 1/7
The surface area of the smaller figure is:
A = k ^ 2 * (A ')
Where
A ': surface area of the largest figure.
Substituting:
A = (1/7) ^ 2 * (588)
A = 12 in ^ 2
Answer:
The surface area of the smallest figure is:
A = 12 in ^ 2
