Answer: $4
The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
There are 540 fuses in total and the original price of the internet is $55.91
<h3>
How to work with percentages?</h3>
a) We know that 5% of the fuses are faulty, and there are 27 faulty fusses, then we can write:
5% = 27
100% = x
We want to find x, to do that, we can write:
x = 27*(100%/5%) = 27*20 = 540
There are 540 fuses in total.
b) Now we know that the original price is P, and when we decrease it by 7%, then new price is $52.00
Then we can write:
$52.00 = P*(1 - 7%/100%)
$52.00 = P*(0.93)
$52.00/0.93 = P = $55.91
The original price is $55.91

Answer:
A 161 square feet
Step-by-step explanation:
5×5=25
1/2 of 25 is 12.5(triangular face) ×2=25
5×8 is 40 (base and left face)
8×7 is 56 (right face)
25+40+40+56=161
F(x) = 3x - 16x - x + 4
f(x) = - 14x + 4
