Step-by-step explanation:
Answer:
Total weight = 24 pounds
Number of helicopters = 3
Step-by-step explanation:
Small helicopters :
Weight = 3 pound
Weight of container = 15
Large helicopters:
Weight = 4
Weight of container = 12
3x + 15 = 4x + 12
3x - 4x = 12 - 15
-x = - 3
x = 3
Total weight of the container :
3(3) + 15
9 + 15 = 24 pounds
Hence, number of helicopters which will fit in either container is 3
The answer to this should be 42
Answer:
Step-by-step explanation:
Given:
The expression to simplify is given as:
We have to simplify this using the properties of exponents.
The property that we use here is:
So, let us simplify the powers of separately and -24 and 8. This gives,
Therefore, the simplified form is:
Answer:
4 or 12.57
Step-by-step explanation:
First, write down the formula for the area of a circle
A=
Then, write down your known values
r = 2
Now, substitute the value r for 2
A =
Then, find the value for
A = (4)
Next, multiply and 4
A = 4
Your answer would be 4 or 12.57, which ever way you need it.
