Answer:
Rate of Pay is $11 per hour.
Step-by-step explanation:
Cost of 
of work = $ 82.50
To find: Rate of pay
Here Rate of Pay means Cost of 1 hour of work or we can say cost of per hour work.
⇒ Cost of 
of work = $ 82.50
Cost of 1 hr of work = 
= 
= 
= $ 11
Therefore, Rate of Pay is $11 per hour.
I think the question is
Find the value of c so that (x-5) is a factor of the polynomial
The other factor is going to be some quadratic. We can say a few things about its coefficients but let's start by saying in general it's
Equating respective coefficients,
so we get
Answer: -37

Answer:
The other side was decreased to approximately .89 times its original size, meaning it was reduced by approximately 11%
Step-by-step explanation:
We can start with the basic equation for the area of a rectangle:
l × w = a
And now express the changes described above as an equation, using "p" as the amount that the width is changed:
(l × 1.1) × (w × p) = a × .98
Now let's rearrange both of those equations to solve for a / l. Starting with the first and easiest:
w = a/l
now the second one:
1.1l × wp = 0.98a
wp = 0.98a / 1.1l
1.1 wp / 0.98 = a/l
Now with both of those equalling a/l, we can equate them:
1.1 wp / 0.98 = w
We can then divide both sides by w, eliminating it
1.1wp / 0.98w = w/w
1.1p / 0.98 = 1
And solve for p
1.1p = 0.98
p = 0.98 / 1.1
p ≈ 0.89
So the width is scaled by approximately 89%
We can double check that too. Let's multiply that by the scaled length and see if we get the two percent decrease:
.89 × 1.1 = 0.979
That should be 0.98, and we're close enough. That difference of 1/1000 is due to rounding the 0.98 / 1.1 to .89. The actual result of that fraction is 0.89090909... if we multiply that by 1.1, we get exactly .98.
Answer:
Step-by-step explanation:
It’s exactly like saying -7 + 3.. -7 is the bigger number so you take away from that the answer is -4
7+9=16 you can use that cause that is the opposite equation
