Answer is 3x(+7)= welcome
The answer is 16.25 adding all of those up
Answer:
56.35 ft^2, or 56 7/20 ft^2
Step-by-step explanation:
One way of doing this problem quickly is to convert both measurements into improper fractions before multiplying them:
9 4/5 = 49/5 and 5 3/4 = 23/4.
Then the area of the garden is 49/5 times 23/4, or 1127/20 ft^2, or
56.35 ft^2, or 56 7/20 ft^2.
Answer:
500
Step-by-step explanation:
Convert percent to decimal:
94%=
100
94
=0.94
Move decimal 2 places to the left
Multiplying the decimal by the whole gives us the part:
0.94x=
0.94x=
470
0.94
0.94x = 0.94
470
Divide both sides by 0.94x=
500
Answer:
6.83 units
Step-by-step explanation:
Let the height of the original pyramid be represented by h. Then the cut off top has a height of (h -2). The scale factor for the area is the square of the scale factor for height, so we have ...
(height ratio)^2 = 1/2
((h -2)/h)^2 = 1/2
(h -2)√2 = h . . . . . . square root; multiply by h√2
h(√2 -1) = 2√2 . . . . add 2√2 -h
h = (2√2)/(√2 -1) ≈ 6.8284 . . . units
The altitude of the original pyramid is about 6.83 units.
