Answer:
C
Step-by-step explanation:
Let's find the area of each of the two circles.
First Circle:
The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:

Second Circle:
The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:

Now, find the ratio between them by dividing:

Simplify:

1/4 is the same as 1:4
So, our answer is C :)
Answer:
It depends how you were taught. You could say it's 11 (eleven) or 2.
Answer:
Divide the 1st equation by 2
a + 2c = 19
Divide the 2nd equation by 3
a + c = 13.5
Subtract the 1st equation and the 2nd equation
c = 5.5
Substituting back into the 2nd equation will give:
a + 5.5 = 13.5
a = 8

Answer:
Divide, 16.
Step-by-step explanation:
So, lets look at the unit scale.
For every 16 ounces, there are 1 pound.
To convert ounces to pounds, the number must be divide by 16, since there are 16 ounces in one pound.
The first fill in box answer is division.
Next we must ifnd the actual amount of pounds.
We know that the box weights 96 ounces.
Now lets divide this by ounces per pound, and see what we get:
96/16
=
6
So the box weighs 6 pounds.
This is the answer to the second fill in question.
Hope this helps!
