Answer:
10
Step-by-step explanation:
sqrt root (x2-x1)^2 + (y2-y1)^2
The flat fee that the store charges is $14 and the cost for 7 hours is $56
A linear equation is on the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
let f for the total rental cost of a vacuum cleaner for x hours
Using the points (1, 20) and (3, 32) from the table:
The flat fee that the store charges is $14
The reasonable domain is 1 ≤ x ≤ 12
The cost for 7 hours is:
f(7) = 6(7) + 14 = 46

Using the pythagoras theorem
side = sqrt (61^2 - 11^2) = sqrt 3600 = 60 in Answer
Based on the number of hours in the work week, the cost of the laborers and masons, worth of the materials and the profit, the estimated cost of the job can be written as a mathematical statement of A. 3 x $15 x 40 + 4 x $25 x 40 + $3,268 + $700 = $
The total estimated cost is $9,768
<h3>What is the total estimated cost?</h3>
The total estimated cost of the job can be found by the formula:
= (Number of laborers needed x Cost of laborers x Number of hours in work week) + (Number of masons x cost of masons x number of hours in work week) + materials worth + Required profit
The total estimated cost is therefore:
= (3 x $15 x 40) + (4 x $25 x 40) + $3,268 + $700
= 1,800 + 4,000 + 3,268 + 700
= $9,768
