Answer:
8y = 7x
Step-by-step explanation:
A = -16
B = 25
C = 5
Plug into the quadratic equation and you get: -0.18 and 1.75. Since we cannot have a negative time our answer is 1.75 seconds.
Answer:
646.04 cm³
Step-by-step explanation:
<u>Cube volume formula:</u>
V=l*w*h
V=8*8*8
V=512
<u>Hemisphere volume formula:</u>
V=(4/3πr³)1/2
V=(4/3π4³)1/2
V=128/3
<u>Add both together</u>
128/3 + 512 ≈ 646.04cm³

According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²
The area of a square is given by the expression:
A = S²
<em>where S is the side of the square - just what we want to know</em>
So:
A = S²
171 = S²
√171 = S
<h3>S ≈ 13.08in</h3>
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
4XZ = 144 ( divide both sides by 4 )
XZ = 36 cm
-------------------------------------------------------
Also
= , substitute values
= ( cross- multiply )
16BC = 192 ( divide both sides by 16 )
BC = 12 cm
