Answer: 15 cm
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
You know that the area of this rectangle is 75 square centimeters and the width is 5 centimeters. Then, you can substitute these values into the formula and solve for the lenght. Then you get:
Therefore, the lenght of the rectangle is 15 centimeters.
You would do 1250 dived by 30.
1250/30 = 41.666
And if you round that, she would need 42 trays.

Answer:
The answer is A. Gymnastics : Minimum of 57, Median of 60, and maximum of 64
Step-by-step explanation:
x² = -7x + 4
x² + 7x - 4 = 0
x = -7 ± √(7² - 4(1)(-4))
2(1)
x = -7 ± √(49 + 16)
2
x = -7 ± √(65)
2
x ≈ -7 ± 8.06
2
x ≈ -3.5 ± 4.03
x ≈ -3.5 + 4.03 or x ≈ -3.5 - 4.03
x ≈ 0.53 or x ≈ -7.53
