Answer 1
9 and then put a pi symbol. You do 3squared since it’s the radius and that’s 9. Then since it’s wanted in terms of pi that’s it. 9pi

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.

Answers

Answer:

U first need to find out the total number of people

22+28

50

and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator

22/50

And now to make it into % we need to ALWAYS multiply the fraction by 100

22/50 x 100

44%

Hope it helps

Answer:

44 %

Step-by-step explanation:

okay so 100% is equal to the whole team or 50 swimmers

100% = 50 swimmers

to find out how much one swimmer is would be to divide the 100% by the total of swimmers.

100% / 50 swimmers

2% = 1 swimmer

so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.

2 x 22 = 44

Which number is equivalent to 7 3/5?

Answers

your answer is D. 7.6!

Answer:

D

Step-by-step explanation:

The whole number 7 stays constant and in order to find the decimal, divide the numerator by the denominator. So  3 divided by 5 equals .6 so therefore the answer is 7.6

6th grade math-
x + 2 =?
x - 2 =?
2x =?
x ÷ 2=?
please help asap :((

Answers

Answer:

x = -2

x = 2

x = ?/2

x = ?(2)

Step-by-step explanation:

For each problem you want to isolate the variable.

For x + 2 you want to move the 2 by subtracting it (since it is being added to the x) from each side. Assuming the other side of the equal sign is 0, the answer is -2.

Same thing for x - 2, isolate by adding the 2 (since it is being subtracted).

For 2x and x ÷ 2 it is a little different. If we assume the opposite side is 0, the answer will be 0 because 0 divided or multiplied by 2 will give you 0. But if the opposite side is a different number, the answer will be that number and then the respected equation for the problem (divide both sides by 2 in 2x because the x is being multiplied by the 2 and multiple both sides by 2 in the x ÷ 2 because the x is being divided by the 2).

THE TOTAL AREA OFTHE FIGURE = AREA OF SQUARE + AREA OF TRIANGLE

where , [tex]a^{2}[/tex] = 19 x 19 = [tex]361 cm ^{2}[/tex]

and ( [tex]\frac{1}{2}[/tex] x b x h) = ( [tex]\frac{1}{2}[/tex] x 6 x 19) = ( [tex]\frac{1}{2}[/tex] x 114) = ( [tex]\frac{114}{2}[/tex] ) = [tex]57 cm^{2}[/tex] =
