The cost of labour per hour is $90.56
The total amount paid by Austin is the sum of the total cost of labour and the cost of the parts
Total amount paid = total cost of labour + cost of parts
$553.50 = total cost of labour + $126
total cost of labour = $533.50 - $126
= $407.50
The total cost of labour = cost of labour per hour x total time worked
$407.50 = xx × 4.5
xx = $407.50 / 4.5
xx = $90.56

No, it does not equal 0. Lets multiply it out and see what it actually equals.
15/25 * 25/15
15*25 / 25*15
375 / 375
Anything over itself is 1, so the final answer for the multiplication is 1.
Answer:
Step-by-step explanation:
8t = 10(1/2t) + 27
8(2t = 10(t) + 27
Number 4 is correct
The value of the composite function fog(1) is -1
Step-by-step explanation:
Step 1 :
Given,
f(-2) = -1
g(1) = -2
We need to find (fog)(1)
Step 2 :
Function f(2) means the value of the function f when x = 2
fog refers to composite function f(g(x)), that is evaluate the function g for x and then evaluate the function f for the result
So to find the composite function (fog)(1) we need to find g(1) first and then apply the function f on the result.
so g(1) = -2
f(g(1))=f(-2) = -1
fog(1) = -1
Step 3 :
Answer :
The value of the composite function is -1
The last one
You’re completing the square here so you have to find (1/2b)^2. In this case it’s 1. So you have to add 1 to both sides. Then you have to solve for it
It becomes
(x-1)^2 = -7
Then you have to find the square root
(x-1) = √-7
x-1 = √7 √-1
x-1= ± i √7
x= 1 ±i √7
That’s your answer and d is the only one that matches with it
