Answer:
As given,
Per hour cost of Jack's plumbing = $100
Also,
Al's plumbing charges = 75x + 50 where x = time in hours .
Now,
Al's plumbing cost for 4 hours:
Here , x = 4
⇒75x + 5 = 75(4) + 50 = 300 + 50 = 350
∴ we get
Al's plumbing cost for 4 hours = $350
Now,
As Jack cost for 1 hour = $ 100
⇒ For 4 hour = 4×$100 = $400
∴ we get
Jack's plumbing cost for 4 hours = $400
As we can see that
$ 400 > $350
⇒Jack's plumbing cost for 4 hours > Al's plumbing cost for 4 hours
Now,
Al's plumbing charges = 75x + 50 where x = time in hours .
For 1 hour
75x + 50 = 75(1) + 50 = 125
Al's 1 hour cost = $125
whereas Jack Plumbing cost for 1 hour = $100
∴ we get
$125 > $100
⇒Al's 1 hour cost > Jack's 1 hour cost
Now,
Al's 2 hour cost
75x + 50 = 75(2) + 50 = 150 + 50 = 200
Al's 1 hour cost = $200
whereas Jack Plumbing cost for 2 hour = $200
∴ we get
$200 = $100
⇒Al's 2 hour cost = Jack's 2 hour cost
Now,
Al's 3 hour cost
75x + 50 = 75(3) + 50 = 225 + 50 = 275
Al's 1 hour cost = $275
whereas Jack Plumbing cost for 3 hour = $300
∴ we get
$275 < $300
⇒Al's 3 hour cost < Jack's 3 hour cost
Als0,
Jack's plumbing cost for 4 hours > Al's plumbing cost for 4 hours
∴ we get
We can not say that Als Plumbing charge less than Jacks Plumbing for all repair jobs.
Because the charge is fluctuating ,
For 1 hour , Aly' charge is grater whereas The 2 hour cost of Jack's is higher.
So, the Correct answer is - No, Al's Plumbing charge is not always less than Jacks Plumbing for all repair jobs.

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
400 compliments for every 850 reviews
Writing the above statement in form of fraction as
= 400/ 850
= 40/ 85
= 8/ 17
Hence, the rate is 8 compliments / 17 reviews

Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)

Answer:

Step-by-step explanation:
You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.
It's the quadratic formula
x = [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]
The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.
a is the coefficient of the first term in the expression, b is the second and c is the third.
so we get[tex]x = \frac{-(-10) +- \sqrt{(-10)^2 - 4(1)(24)} }{2(1)}[/tex] , which is the same as
[tex]x = \frac{10 + \sqrt{100 - 24(4)} }{2}[/tex]
and
x = [tex]x = \frac{10 - \sqrt{100 - 24(4)} }{2}[/tex]
The top part simplifies to [tex]\frac{10 + \sqrt{100 - 72} }{2} = \frac{10 + 6}{2} = 5[/tex], which is your answer.

Hypotenuse of 14
Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x

exam. What was the average grade on the midterm exam for the entire class?
Answer:
They average 84%
Step-by-step explanation:
Just add 77 and 91 then divide it by 2. Hope this helps.
Answer:
83 is the correct answer if you just do it by adding 91 and 77 then diving it by 2 you would get 84 that is not what answer they are looking for. Took the test 83 is what they are looking for they want you to do the work.
Step-by-step explanation:
Tenth graders 12*77= 924
Eleventh graders 9*91= 819
924+819= 1,743
12 tenth graders and 9 eleventh graders
12+9 = 21
