Answer:
<em>165ft</em>
Step-by-step explanation:
Ratio of actual walkway and a model is :
60 ( Ft ) : 15 ( in) or : 15 : 1
EF = 60 Ft,
FG = 30 Ft,
GH = 30 Ft,
HE = 45 Ft.
60 + 30 + 30 + 45 = 165 Ft
Answer: $1,540
Step-by-step explanation:
Given the following amount charged by a worker :
First 45 hours = $14 per hour
time and half for the next 10 hours
Double time for all hours after that:
If he worked for 80 hours :
First 45 hours = (45 × $14) = $630
Next 10 hours:
Time and half for 10 hours is equivalent to (10 × 1.5) = 15 hours
(15 × $14) = $210
Double time for all subsequent hours :
80 - (45 + 10) = 80 - 55 = 25
Double time : (2 × 25) = 50 hours
(50 × 14) = $700
Hence, total amount earned :
($630 + $210 + $700)
= $1,540
The answer is the product of 7 and the difference of b and - 2
I hope choices must be given in the problem.
I am showing the method to find the equivalent equation of the above equation. You can match with your given choices.
First step is to expand the first term. So,
(x-4)² = (x - 4)(x - 4) Since a²= a*a
= x² - 4x - 4x + 4 * 4 By multiplying.
= x² -8x + 16 Combine the like terms.
So, (x - 4)² - (x -4) - 6
= x² - 8x + 16 - x + 4 - 6
= x² - 9x + 14 Combine the like terms.
So, equivalent equation of the above equation is x² - 9x + 14 = 0.
