my answer is in the image above
-512.
Type negative 8 to the third power in google. It really is the answer. :)
Hi! The answer for the first one is 500
50 times 9=450
10% is 50
50 times 10= 500
The original price was 500.
The discount was $50
For the second one the answer is $10
The discount was $7
10-7=3
10% is 1 , 30% is 3 and 70% is 7
Answer:
b = 7
Step-by-step explanation:
Given
8 - (3 + b) = b - 9 ← distribute parenthesis on the left by - 1
8 - 3 - b = b - 9, that is
5 - b = b - 9 ( subtract b from both sides )
5 - 2b = - 9 ( subtract 5 from both sides )
- 2b = - 14 ( divide both sides by - 2 )
b = 7
R = 7 d = 14 (to find the radius d ÷ 2) h = 10
(2πr²)
2 x 3.14 x (7x7)
2 x 3.14 x 49 = 307.72
(πdh)
3.14 x 14 x 10 = 439.6
Take the two answers and add.
307.72 + 439.6
Final answer = 747.32
