0. a local lawn service charges $6.00 per cut plus $2.50 per gallon of gas
used. write an algebraic expression to represent the amount they charge
per cut. let g = the gallons of gas used.

C = 6 + 2.5g

Step-by-step explanation:

A local lawn service charges $6.00 per cut plus $2.50 per gallon of gas  used.

If in a cut g gallons of gas is used then, the cost for gas used will be $2.5g and there is a fixed charge of $6.00 per cut.

Therefore, in total the cost per cut becomes 6 + 2.5g and if we represent the total cost as C, then we can write  

C = 6 + 2.5g. (Answer)

answer:      

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
