The diameter is the radius doubled. So, the radius CK is 2, so the diameter would be 4.

now, the x-axis has years after 1987, so 2007 is 20 years after 1987, 1987 + 20 = 2007, therefore x = 20, what is y?............
.
and you know how much that is.
Find the sum of the p to both terms in the parentheses
p(10-2)
p(8)
8p is another way to write the expression
STEP 1:
First we need both in the same unit of measurement.
1 pint= 2 cups
Convert 15 cups to pints:
=15 cups ÷ 2 cups per pint
=7.5 pints
STEP 2:
Find percentage:
=8 pints ÷ 7.5 pints
=1.0666 decimal percent of 8 pints
STEP 3:
Convert to %:
=1.06666 x 100
=106.66% percent 8 is of 7.5 pints
*TIP: if you know you're changing to a percentage from a decimal, you will always move the decimal two places to the right.
ANSWER:
8 pints is 106.66% of 7.5 pints.
Hope this helps! :)
<h3>
Answer: 104</h3>
Explanation:
Convert the given fraction to decimal form 8/25 = 0.32
Then multiply it with the school population 0.32*325 = 104
We expect about 104 students walk to school
Note how 104/325 = 0.32, so 104/325 = 8/25
