The answer is 28.26
work:
Equation for area of circle: pi*radius squared
the radius of the circle is 3
3 squared is 9
9 times 3.14 is 28.26
It’s 8n-12 because it’s trying to find the difference so you would replace the and with the subtraction sign
paint is needed to cover an entire wall : 2
if 1/2 gallon of paint cover 1/4 of a wall => 1 wall = (1/2)/(1/4) =2
Answer:
$2500
Step-by-step explanation:
The amount of simple interest is computed using the formula ...
I = Prt
where P is the principal amount of the loan, r is the annual rate, and t is the number of years. Filling in the given information, we have ...
425 = P·0.085·2
P = 425/0.17 = 2500 . . . . divide by the coefficient of P
The original amount of the loan was $2500.
Answer:
x = 8.5
Step-by-step explanation:
You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°
The sum of all angles is 180°
90 + (4x - 8) + (6x + 13) = 180
10x + 95 = 180
- 95 -95
10x = 85
x = 8.5
