The formula for the area of a trapezoid is a=1/2(b1+b2)h
So 10*5 = 50 *4 = 200 then divided by 2 is 100 so the answer is 100
Answer:
$482.625 ≈ $482.63
Step-by-step explanation:
y · 100 = 450 · 7.25
100y = 3262.5
100y ÷ 100 = 3262.5 ÷ 100
y = 32.625
$450 + $32.625
$482.625

Step-by-step explanation:
A prime number is a number that you don't get a whole number when divided by 2 but you do get a whole number when divided by prime numbers such as 3,5,7,11... Basically a number with two factors, it can only be divided by 1 or themselves. for example:
9/2 = 4.5 (this is not a whole number so it might be a prime.
9/3 = 3 (it works when divided by a prime number.
another:
8/2 = 4 (it gives a whole number when divided by 2 therefor, it can't be a prime number.
