Well so it is asking you the statements and reasons and there is a select button it would be..... Hold on think about the letter formation. Just choose your best answer you think it is because if we are telling you thats cheating. But look above what I said. Think of the letter formation and quardinate with the question. I am speeding and yes I know I spelt it wrong.

Answer: he needs to buy 578.5 yard² of Sod.
Step-by-step explanation:
Assuming the lawn is square shaped, the formula for determining the area of a square is
Area = length²
If the length of each side of the lawn is 24 1/2 = 24.5 ft
Area of the lawn = 24.5² = 600.25yard²
The area of the pool house is 16yard²
The area of the side walk is
3 × 1 = 3 yard²
The length of the pool is 7 1/2 = 7.5yards
The width of the pool is 2 1/2 = 2.5 yards. Therefore,
Area of pool = 7.5 × 2.5 = 18.75 yard²
Therefore, the amount of Sod that he needs to buy is
600.25 - (3 + 18.75) = 600.25 - 21.75
= 578.5 yard²
Answer:
4 2/7
Step-by-step explanation:
It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)
_____
The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...
... 8, 5, 2, 1, 3, 5, 6
and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...
... 30/7 = 4 2/7
_____
<em>More about Absolute Deviation from Average</em>
"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...
... |0 - 8| = |-8| = 8
For 3, it is ...
... |3 - 8| = |-5| = 5
Answer:
4
Step-by-step explanation:
Simplify the following:
2^5/2^3
Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 2^5/2^3.
Combine powers. 2^5/2^3 = 2^(5 - 3):
2^(5 - 3)
Hint: | Subtract 3 from 5.
5 - 3 = 2:
2^2
Hint: | Evaluate 2^2.
2^2 = 4:
Answer: 4
