6. The basketball team of Martin Luther Kind High School won 12 of its first 15 game. It then won its next 3 games. Its winning percentage was then:

7. A circular track is 1000 yards in circumference, Cyclists A, B, and C started at the same place and time, and race around the track at the following rates per minute: A at 700 yards, B at 800 yards, and C at 900 yards. What is the least number of minutes it must take for all three to be together again?

5 is actually 10 yards

perimeter = 9 + 6 = 15 * 2 = 30

then convert to yards
30 / 3 = 10 yards

7. 40 questions
8. 50400 minutes

I don't get #3??

1. To find the number of gallons of paint needed to cover the two walls, we first need to calculate the total surface area of both walls.

For the first wall, which is 36' by 8', the area is calculated by multiplying the length by the width:
Area of the first wall = 36' * 8'

For the second wall, which is 24' by 9', the area is calculated by multiplying the length by the width:
Area of the second wall = 24' * 9'

Once we have the total area of both walls, we divide it by the coverage of one gallon of paint (224 square feet) to find the number of gallons needed:
Number of gallons needed = (Area of first wall + Area of second wall) / Coverage of one gallon of paint

2. To find the total amount of paint Susan needs, we need to calculate the quantity of each color. Let's assign a variable to one of the colors, say yellow paint.

Given that Susan needs 3 times as much blue paint as yellow paint, we can say:
Quantity of blue paint = 3 * Quantity of yellow paint

Given that she needs 1/2 as much yellow paint as green paint, we can say:
Quantity of yellow paint = 1/2 * Quantity of green paint

Given that she needs 3 1/4 gallons of pink paint, which is 3/4 of a gallon more than the green paint, we can say:
Quantity of pink paint = Quantity of green paint + 3/4

To find the total amount of paint she needs, we sum up the quantities of each color:
Total quantity of paint needed = Quantity of blue paint + Quantity of yellow paint + Quantity of green paint + Quantity of pink paint

3. To calculate the cost of material for four curtains, we need to find the total length of material required.

Each curtain requires 4 yards 1 foot of material, which can be written as 4 yards + 1 foot. Since there are 3 feet in a yard, 1 foot is 1/3 of a yard. So, the length of material required for each curtain is 4 1/3 yards.

To find the total length of material required for four curtains, we multiply the length of one curtain by the number of curtains:
Total length of material required = Length of one curtain * Number of curtains

Finally, we multiply the total length of material required by the cost per yard ($3) to find the total cost of the material.

4. To calculate the number of complete turns a tractor wheel will make in rolling one mile on the ground, we need to find the circumference of the wheel in feet.

The circumference of the wheel is given as 88 inches. Since there are 12 inches in a foot, we convert it to feet by dividing by 12:
Circumference of the wheel in feet = 88 inches / 12

Next, we convert the distance of one mile to feet:
One mile = 5280 feet

To find the number of complete turns, we divide the distance in feet by the circumference of the wheel in feet:
Number of complete turns = One mile / Circumference of the wheel in feet

5. To calculate the number of yards of molding needed to hold the linoleum around the outside edge of a kitchen floor, we need to find the perimeter of the floor.

The perimeter of a rectangle is calculated by adding all four sides:
Perimeter = 2 * (Length + Width)

Once we have the perimeter in feet, we divide it by 3 to convert it to yards:
Number of yards of molding needed = Perimeter in feet / 3

6. To calculate the winning percentage of the basketball team, we need to determine the ratio of games won to the total number of games played.

Given that the team won 12 of its first 15 games, we calculate the winning percentage as follows:
Winning percentage = (Number of games won / Total number of games played) * 100

7. To find the least number of minutes it takes for all three cyclists to be together again, we need to find the least common multiple (LCM) of their respective distances around the track in yards.

The distances each cyclist covers in a minute are given as follows:
Cyclist A: 700 yards
Cyclist B: 800 yards
Cyclist C: 900 yards

To find the LCM, we find the smallest number that is divisible by all three distances. This will give us the number of minutes it takes for all three cyclists to be together again.
