Answer:
85 ft^2
Step-by-step explanation:
The four sides of the pyramid: 5×6÷2×4=60
The bottom of the pyramid: 5×5=25
60+25=85 ft^2
We are given ratio 456:8.
The given ratio can be written in fraction form as 
In order to find the rate, we need to divide 456 by 8, because it would give the unit value.
When we divide 456 by 8, we first take multiple of 8 closer to the number 45.
8*6=48 but it's greater than 45, so we would take 8*5 =40.
Subtracting 40 from 45, we get 5.
Getting 6 down, we get 56. Take multiple of 8 upto 56.
8*7= 56.
56 -56=0.
So, on dividing 456 by 8 we got 57.
Therefore, rate is 57 per unit.
Answer : 1.4 x 10^-9
Step-by-step explanation:
0.0000000014
= 1.4 x 10^-9
Firstly, you can combine like terms, or terms that have the same variable and exponents.
24x and 4x both have the variable "x" so it can be combined to make 28x
A coefficient is basically just the number that's used to multiply the variable
In this case, the variable is "x" and the number that will be multiplied to x is 28.
<em>The coefficient is 28.</em>
