Answer:
Step-by-step explanation:
1.2307692307692.
The first step is to find the proportionality constant.
The formula is
z = kx/y
1.2307692307692 = k * 4/13 Multiply both sides by 13
1.2307692307692 * 13 = 4k
16 = 4*k Divide by 4
k = 16/4
k = 4
=================================
z = k*x/y
x = 9
y = 20
k = 4
z = 4 *9/20
z = 36/20
z = 1.8
Every point on line a is also on line b and line a is parrel to line b
Answer:
I believe that it is 2, I'm not 100% but ill take the guess
Step-by-step explanation:
3. (a.)
<span>Volume of block = 20 cm x 9 cm x 8 cm = 1440 cm^3 </span>
<span>(b.) </span>
<span>Volume of cylinder = pi * (radius)^2 * (height) </span>
<span>Plugging dimensions in: </span>
<span>Volume = pi * (10 cm/2)^2 * (15 cm) </span>
<span>= pi * (5 cm)^2 * (15 cm) </span>
<span>= 1178 cm^3 to the nearest centimeter </span>
<span>(c.) </span>
<span>Remaining volume = 1440 cm^3 - 1178 cm^3 = 262 cm^3 </span>
<span>Volume of cube = side^3 = 262 cm^3 </span>
<span>Taking cube root, side = 262^(1/3) = 6 cm to the nearest cm</span>
