Answer:
24 feet
Step-by-step explanation:
Let w represent the width of the rectangle. Then its length is 2w, and its area is ...
A = Lw
32 = (2w)(w) = 2w^2 . . . fill in the given values
16 = w^2 . . . . . . . . . . . . divide by 2
4 = w . . . . . . . . . . . . . . take the square root
8 = 2w = L . . . . . . . . . find the length
The dimensions of the yard are 8 feet long and 4 feet wide.
__
The perimeter is ...
P = 2(L +w) = 2(8 +4) = 2(12) = 24 . . . . feet
The perimeter of the rectangular back yard is 24 feet.
Solve the formula for h, so you need to isolate/get h by itself in the equation:
A = 1/2bh Multiply the inverse of 1/2, which is 2/1 or 2 on both sides to get rid of the 1/2
2A = bh Now divide by b on both sides
Your answer is C
Answer:
The pedals
Step-by-step explanation:
A tricycle requires 3 tires, 1 frame, and 2 pedals.
Divide all the amounts by the amounts needed for one tricycle.
270/3=90
90/1=90
170/2=85
The pedals can only be assembled onto 85 tricycles while everything else can be assembles into 90 tricycles.
Sin=opposite/hypotenuse
The opposite of B is 3 and the hypotenuse is 5.
Therefore the answer for 1 is D 3/5.
cos=adjacent/hypotenuse
The adjacent of B is 4 and the hypotenuse is 5.
Therefore the answer for 2 is B 4/5.
