Answer:
cost for (not per) 1 sq ft. floor: $84.79
y = total costs
x = sq ft of flooring
y = x4.79 + 80.00
Step-by-step explanation:
i this equation, y = the total cost wile x = square ft. of flooring
to find out the price when we know that 60 sq ft is $287.00 without the instalation fee, all we have to do is divide 287.00 by 60
287 / 60 = 4.79
so we now know how much 1 sq ft. costs, but to implament it into an equation we need to multiply it by the amount of flooring, so we let x be the number of sq ft used
now all we have to do is add the instalation fee, no, we literally add it in the equation at the end, so that it is added after we multiply by sq ft (not before) then after we calculate that, we get the total cost for x sq ft of flooring, or y
hope this answers your question
Answer:
0.0089
Step-by-step explanation:
Because when we want to change decimal as percents we need to replace the period on the left side 2 times. But when we want to change percent as a decimal, then we need to move the period 2 times on the right.
ex:
.72 decimal= 0.0072

EXPLANATION
The equation is representing the word problem x (any unknown) plus 3 is no greater then 12. Both problems have one value that is 3, an unknown value and are at machining or most 12. In other words booth problems work for the problem.
Answer:
The nonresponse rate is 52 percent.
Step-by-step explanation:
150 sampled:
72 returned and 150 - 72 = 78
The nonresponse rate is
Percentage that 78 is out of 150, that is:
78*100%/150 = 52%
The nonresponse rate is 52 percent.
