Answer:
$47,520
Step-by-step explanation:
A.
the area of a polygon is/
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=
$47,520
Step-by-step explanation:
x = 90- 55 = 35
y = 180- x
y= 180 - 35 = 145
z =180- (y +10)
z = 180 - (145 +10)
z = 180-155
z = 25

<span>the answer is 24 marbles is 40 percent of 60</span>
LOL and how you would convert it is when you say a fraction EX:23 3/10, you say it like twenty three AND three tenths. So, you would write it as a decimal just like the way you would say it as a fraction.(Just think that the decimal point is the AND)EX: 23(.)3. The three is in the tenths place and it is called three tenths.

Answer:
- k = 40 lb/in²
- B. 20 inches
Step-by-step explanation:
Fill in the given numbers and solve for k.
y = kx²
1000 lb = k(5 in)²
(1000 lb)/(25 in²) = k = 40 lb/in² . . . . . . divide by the coefficient of k
__
Fill in the given numbers and solve for x.
y = kx²
16000 lb = (40 lb/in²)x²
16000 lb/(40 lb/in²) = x² = 400 in² . . . . . . divide by the coefficient of x²
20 in = x . . . . . . . . . take the square root
The depth to support 16,000 pounds should be 20 inches.
