Answer:
8 16 24 32 <u>40</u> 48 56 64 <u>72</u>
1 2 3 4 <u>5</u> 6 7 8 <u>9</u>
Step-by-step explanation:
The proportion is 8:1
When the dollar amounts increase by 8, the hour amounts increase by 1, and vice versa. That is why it is a proportion.
So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
The answer is: " 9a² + 7a " .

Note: (3a)² + 7a = (3a)*(3a) + 7a = 9a² + 7a .

10/8 = 1.25 oz.
there are 8 ounces in 1/2 of a pound. if you divide 8 by 10 bags it equals 1.25 ounces in each bag
