Step-by-step explanation:
Answer: 9/4
Step-by-step explanation: Think of 
as 
.
Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and
we can change 9⁻¹ to 9¹ by moving it to the numerator.
So we have 9¹/4¹ which simplifies to 9/4.
a. Let's start with "the sum of one-half and one-third." Sum tells us to add. This would translate to 1/2 + 1/3. Now, it's telling you to find 1/5 of that. So you multiply this by 1/5.
Your final expression is (1/5)(1/2 + 1/3)
b. "the sum of nine and twelve" is more obvious; 9 + 12. Now, multiply it by "two and one-half"
Your final expression is (2 1/2)(9 + 12)
c. "difference between 1 1/2 and 3/4." Difference tells us to use subtraction. 1 1/2 - 3/4. "twenty-four divided by" tells you that that part of the equation belongs in the denominator.
Your final expression is 24 / (1 1/2 - 3/4)
Answer:
Apparently i cant see the photo im am so sorry but do need pints.
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2. a and b are the legs, and c is the hypotenuse. Plug in your numbers: 9^2 + b^2 = 12^2
81 + b^2 = 144. Subtract 81 from 144 : b^2 = 63. Now take the square root of 63, which is 7.9. 7.9 ft is your answer.
