Maura drew a scale drawing of a house and its lot. The scale of the drawing was 1 inch : 2 feet. In the drawing, the porch is 6 inches wide. What is the width of the actual porch? Is it 12???

Answers

Yes, the porch is 12 feet wide.
If 1 inch = 2 feet, and if she makes the porch 6 inches wide, then you multiply the 6inches by 2, since 1 inch is equal to 2 feet.

It is 12 feet ya it is the answer that is it

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

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
