50-8 = 42
42/2 = 21
21+8= 29
Nickels-29
Quarters-21
Double Check
29+21 = 50
Answer:
<h2>12.5 millimeters (mm).</h2>
Step-by-step explanation:
<u>Explain/define:</u>
<u>CIRCUMFERENCE: THE DISTANCE AROUND A CIRCLE.</u>
<u>DIAMETER: THE LENGTH OF A STRAIGHT LINE THROUGH THE CENTER OF A CIRCLE.</u>
<u>Mathematics: Formula</u>
<u>Mathematics: Solve</u>
To find the length of the diameter from the circumference, divide the circumference by pi. The quotient is the diameter.
3.14 is often used for pi.
<u>Conclude:</u>
Therefore, the length of the diameter of the circle is 12.5 millimeters (mm).
No because being proportional only relates to multiplication not addition or subtraction.
hours each day.
Step-by-step explanation:
The given function models the number of cars that are put through a quality control test each hour at a car production factory.
The given function is
We need to find the number of hours does the quality control facility operate each day.
Rewrite the given function it factored form.
Taking out the common factors from each parenthesis.
The factored form of given function is c(t)=-(t-10)(t+2).
Equate the function equal to 0 to find the x-intercept.
Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.
Therefore the quality control facility operates for 10 hours each day.
