A) If you cut off half the peaks (3.5 ft down from the top), they will just fill the valleys making a rectangle 18.5 ft by 30 ft. The area is the product of these dimensions.
A = (18.5 ft)*(30 ft) = 555 ft²
b) To determine the number of quarts of paint required, divide this number by 90 ft². Since you cannot buy a partial quart, if there is any remainder, use the next higher integer number of quarts.
555/90 ≈ 6.2 so Pat should buy 7 quarts of paint.
Answer:
The areas are equal.
Step-by-step explanation:
Let the first rectangle be R and
the second rectangle be R'.
Sine R and R' are identical, their lengths are equal and their breadths are equal.
So, if Inga divided each into equal parts, then each part of both rectangles are equal.
Hence, the colored parts of both rectangles are equal.
Answer:
1/10 or 10%
Step-by-step explanation:
1/4 x 2/5 = 1/10 (10%)
Answer:
Step-by-step explanation:
The equation of the ellipse is
If the vertex of the ellipse is at point (-7,0), then a=7.
If the co-vertex of the elllipse is at point (0,-5), then b=5.
The equation of the ellipse is
Step-by-step explanation:
x² + 2x
x(x + 2)
<u>OR</u>
x² + 2x = 0
x(x + 2) = 0
x = 0 or x + 2 = 0
x = 0 or x = - 2
