Answer:
64
Step-by-step explanation:
The volume of rectangular prisms is measured by l*w*h
And by counting the units of the length, width, and height are all 4 units long.
So take the numbers and plot them into the formula
4*4*4 = V
16 * 4 = V
64 = V
The prism is 64 cubic units.
This is combining like terms:
-6x - 3x + 7x = -2x
Answer:
-2x + 4y + 8
Neighborhood A: 30 homes and increases by 20% per year
Neighborhood B: 45 homes and increases by 3 per year.
N.A = 30 (1.20)^t
N.B = 45 + 3(t)
t = 5
N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
<span>N.B = 45 + 3(5) = 45 + 15 = 60</span>
Answer:
0.46%
Step-by-step explanation:
0.0046*100%= 0.46%
A rational number can be written as a ratio and is nonrepeating. There is an infinite amount of numbers between 7.7 and 7.8, but an easy one is
7.75. You can double check that it's rational by writing it as a ratio,
, and you can see that it isn't repeating.
