Acollege football stadium holds 45,000 fans. in a random sample of 30 fans, 25 were wearing the colors of the home team. predict the number of fans who are wearing the colors of the home team.

A

Step-by-step explanation:

Remark

Just as a guess, the answer should be A or B. It's always a good idea to estimate an answer so that if you get something really far away, you know it is incorrect.

Equation

Set up a proportion for the problem

26/30 is the basic ratio of the home fans wearing the right color

x/45000 is the ratio of those in the entire stadium.

Solution

26/30 = x / 45000                 Cross multiply

30x = 26 * 45000                  Simplify the right

30x = 1170000                        Divide by 30

30x/30 = 1170000/30    

x = 39000 And that is A

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
