The answer would be: 63 < 2j (im so sorry if I’m wrong)
Hello!
The best estimate for the height of a desk is a meter. One kilometer is equal to 1,000 metres. A desk is obviously not 1,000 metres high because, well, our roofs wouldn't be that high!
The area would be 441 m².
We first find the length of the given rectangle. We know area is length times width, that the area is 405 and the width is 15; this gives us:
405 = 15L
Divide both sides by 15:
405/15 = 15L/15
27 = L
Calculate the perimeter of the rectangle:
P = 2L + 2w = 2(27) + 2(15) = 84 m
The side of the square is 1/4 the perimeter of the rectangle we just found:
1/4(84) = 21 m
The area of a square is equal to its side length squared:
A = s² = 21² = 441 m²
The equation to find Amy's earning after tutoring for 15 hours is 300 dollars.
<h3>How to find an equation?</h3>
She earn 20 dollars for each hours she tutors.
E = earnings in dollars
H = hours of tutoring
The equation relating E and H are as follows:
E = 20H
Therefore, the equation to find Amy's earning after tutoring for 15 hours is as follows;
E = 20H
E = 20 × 15
E = 300 dollars
Therefore, Amy's tutoring for 15 hours is 300 dollars.
