Answer:

Step-by-step explanation:
Since there are 18 inches of snow already, 18 is our constant term in the function. Then, we describe x to be the number of hours that it snows for. We multiply this by 4 to find how many inches of snow fell during those hours. We add this term to the constant term to get the solution to y or 
$1.08
you would multiply your cost (1.00) by 8% which is equivalent to .08 and then add to to the original cost. or to skip the middle step just multiply it by 1.08 since you are adding the 8% to 100% of the original cost
Answer:
Fri. $10
Sat. $40
Sun. $20
Step-by-step explanation:
earnings on Saturday=x
Sunday is .5*x, which is 1/2 of Saturday
Friday is .25*x, which is 1/2 of Sunday
x+.5x+.25x=70
(simplify)1.75x=70
Divide by 1.75 1.75x/1.75=70/1.75
X=40
then plug in x for all days
Answer:
Class width = 20
Approximate lower class limit of the first class = 110
Approximate Upper class limit of the first class = 119
Step-by-step Explanation:
The class width of the histogram attached below can be gotten by finding the difference between successive lower class limits.
Thus, class width = 130 - 110 = 20
The approximate lower class limit of the first class is the lowest score we have in the first class = 110
The approximate upper class limit of the first class is the closest highest score that fall within the first class and is below the lower limit of the second class. Thus approximate upper class limit of the first class = 129
