For 1. The bike is going 24 miles in 3 hours. To figure out how many miles it went in 1 hour you divide 24/3 which is 8 miles. If the bike went 8 miles per hour then you may now multiply it by 10 to find the total mileage in 10 hours. 10x8=80

Collins is working.......
lesya [120]
Let n represent the amount Colin earned on Sunday.

On Sat. he earned n/2; on Sun. he earned n; and on Friday he earned (1/2)(n/2).

Then n/2  +  n  + n/4 = $70

Mult. all terms by 4 to eliminate fractions:

2n + 4n + n = $280

7n = $280  =>  n = $40

Colin earned n/2, or $20, on Saturday; n, or $40, on Sunday; and n/4, or $10, on Friday.

Note that $20 and $40 and $10 add up to $70, as they must.

If (2 − 3i) + (x + yi) = 6, what is x + yi? 4 + 3i 4 − 3i -4 − 3i -4 + 3i 4x + 3i
Jobisdone [24]
<span>If (2 − 3i) + (x + yi) = 6, to get x + yi we subtract (2-3i) from both sides of the equation.

</span>(2 − 3i) + (x + yi) - (2 − 3i) = 6 -(2 − 3i) 
(x + yi) = 6 - (2 - 3i)
Open the parenthesis taking care of the signs 
(x + yi) = 6 - (2 - 3i)
            = 6 - 2 + 3i
            = 4 + 3i

The histogram below shows information about the number of books students read in a month:
ira [324]

Answer:

Step-by-step explanation:

This information provides the number of students who read a certain range of books. Those ranges are provided 0 to 4 (inclusive) 5 to 9 and 10-14.

Since 9 books or more covers two bins, this cannot be the answer.

The information doesn't offer specific values just ranges, so both the mean and median cannot be determined.

So the answer is C, the number of students who read 4 books or fewer.
