A square field has an area of 479 ft2. What is the approximate length of a side of the field? Give your answer to the nearest foot. Explain your response.
To find the length of a side of the square field, we need to take the square root of the area.
The square root of 479 is approximately 21.9.
Since we are asked to give the answer to the nearest foot, the approximate length of a side of the field is 22 feet.
Simplify the expression (7+5)+4⋅13−2
.
To simplify the expression, we first perform the multiplication:
4 ⋅ 13 = 52
Then, we perform the addition:
(7 + 5) + 52 - 2
The addition within the parentheses simplifies to:
12 + 52 - 2
Finally, we perform the remaining addition and subtraction:
12 + 52 = 64
64 - 2 = 62
Thus, the simplified expression is 62.
