Answer:
30/(5+7)
Step-by-step explanation:
The area of the classroom is 768 square feet
9^2 × 9^6=9^10/9^2
When multiplying exponents, if the bases are the same you add the exponents.
9^2 × 9^6 = 9^(2+6)=9^8
When dividing exponents, I'd the bases are the same you subtract the bottom exponent from the top.
9^10/9^2=9^(10-2)=9^8
9^8=9^8
Solution: 9^10 over 9^2
Hello!
a. You have to find 45% of 1,200. To find percents, change the % to a decimal and multiply
45% = 0.45
0.45 × 1,200 = 540

_________________________________________________________
b. You have to find 15% of 56. To find percents, change the % to a decimal and multiply.
15% = 0.15
0.15 × 56 = 8.4
