You'll need to learn the formula for the circumference of a circle. If the radius is r, the circumference C is C = 2πr. It appears that your teacher is using pi for the exact circumference and 3.14 for the approximate circumference.
The radius of the first circle is 5 in. Thus, the exact circumference is
C = 2πr = 2π(5 in) = 10π in, and the approximate circumference is
C = 2(3.14)(5 in) = 31.4 in
9) There are six girls and 12 boys in Ms. Jeffry's environmental club. She wants to divide the students into groups with the same number of boys and the same number of girls in each group. What is the maximum number of groups she can make? *
No . of girls in Ms. Jeffry's environmental club = 6
No . of boys in Ms. Jeffry's environmental club = 12
To find the maximum number of groups she can make , we have to find the highest common factor ( HCF ) of the number of boys and girls in her club .
Factors of 6 = 1 , 2 , 3 and 6
Factors of 12 = 2 , 3 , 4 , 6 and 12
Hence the highest common factor of 6 and 12 are 6 .
Therefore , the maximum number of groups Ms . Jeffry can make where the number of girls and boys are same are 6 .
Jenny is making tie dyed shirts for her class with her school colors, blue and yellow she used a total of 8 ounces of fabric paint the amount of blue paint is 3 times the amount of yellow make a diagram to show the ratio of blue to yellow paint
Answer:
The ratio of blue paint to yellow paint is 3:1
Step-by-step explanation:
Let
x -----> the amount of blue paint in ounces
y ----> the amount of yellow paint in ounces
we know that
x+y=8 -----> equation A
x=3y -----> equation B
Solve the system by substitution
Substitute equation B in equation A
3y + y = 8
4y = 8
y = 2
Find the value of x
x = 3(2) = 6
therefore
The amount of blue paint is 6 ounces and the amount of yellow paint is 2 ounces
Find the ratio
To find out the ratio of blue paint to yellow paint, divide the amount of blue paint by the amount of yellow paint
x/y = 6/2 = 3/1
That means -----> Of every 4 parts of paint, three parts are blue and one part is yellow.

Nicolas is setting up water stations for a 10-mile run. He already has the first one set up 8 miles from the starting line. He needs to set up two more that are 1.5 miles on either side of the first water station. Where will he put the two additional water stations?
A number line divided into increments of 1 and labeled 0 through 10. The number 8 is labeled with Nicolas.
The absolute value equation that models this situation is |x –
|=
.
The two additional water stations will be
and
miles from the starting line.
Answer:
Step-by-step explanation:
The two additional water stations will be 6.5 miles and 9.5 miles away from the starting line.
Given Nicolas is setting up 3 water stations for a 10-mile run.
He already has the first one set up 8 miles from the starting line. He wants to set up two more that are 1.5 miles on both side of the first water station.
We have to calculate the distance of 2 other water station from starting point.
Now A number line divided into increments of 1 and labeled 0 through 10. The number 8 is labeled with Nicolas.
The absolute value equation that models this situation is |x –8 |=1.5
The two additional water stations will be (8-1.5) miles or 6.5 miles and other will be (8+1.5) or 9.5 miles away from the starting line.
The two additional water stations will be 6.5 miles and 9.5 miles away from the starting line.

The probability that a randomly-selected person at a show has seen the band play live before is 50%. A "superfan" is defined as someone who has seen the band play live at least 5 times. The probability that a person at a show is a "superfan" is 30%. Two people are selected at random. What is the probability that both people have both seen the band perform live before, and are "superfans?"
Answer:
0.25 and 0.09
Step-by-step explanation:
The probability that a randomly-selected person at a show has seen the band play live before is 50%=0.50
The probability that a person at a show is a "superfan" is 30%=0.30
Two people are selected at random.
The probability that both people have both seen the band perform live before
= The probability that the first person has seen the band live before and the second person also has seen the band live before.
=0.50 x 0.50
=0.25
Similarly, the probability that both are "superfans"
=The probability that the first person is a superfan and the probability that the second person is a superfan.
=0.30 x 0.30
=0.09
Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.25 and 0.09 respectively.

What are the Properties of Multiplication?Certain rules that are used while multiplying numbers are known as the characteristics of multiplication. All types of mathematical expressions, whether they be algebraic expressions, fractions, or integers, can be solved thanks to these features, which make it simple to simplify expressions.
Given expression 6(1/3 • 7/5),
to write its associative property
The Associative Property of Multiplication states that altering the way the numbers are grouped has no impact on the result of the multiplication.
a(b . c) = (a . b)c
6(1/3 • 7/5) = (6 • 1/3)7/5
Hence correct expression for the property is option B, (6 • 1/3)7/5.

How do you solve this equation? x/2 - x = x/4 + 6
Answer:
x= - 8
Step-by-step explanation:
multiply both sides by 4 to get rid of the fractions. you should then get:
2x-4x=x+24
then get all the x terms to one side by subtracting by x on each side:
2x-4x-x=24
then simplify:
-3x=24
divide by -3 on each side:
x= - 8

3/4x + 2/5 = 4x - 1/4x
Answer:
4/45 = x
Step-by-step explanation:
Strongly suggest that you enclose the fractional coefficients inside parentheses to reduce possible ambiguity:
(3/4)x + 2/5 = 4x - (1/4)x
Consolidate the x terms on the right side and leave the 2/5 on the left:
2/5 = (4 - 1/4 + 3/4)x, or
2/5 = (4 1/2)x or 2/5 = (9/2)x
Solving for x: Multiply both sides by (2/9):
(2/9)(2/5) = (2/9)(9/2)x, or:
4/45 = x
