The correct answer is A. Number of hours worked
Explanation:
In the equation presented, the number of hours worked is the only factor that varies, it is expected the plumber has to work a different number of hours depending on each situation and this affects the final cost as the number of hours is multiplied by $25 (cost of one hour). On the other hand, factors such as the house call charge or the price of an hour for labor are fixed and do not change.
Moreover, in equations, the factor that changes and can affect others is known as the independent variable. This means the number of hours can be classified as the independent variable because this is not fixed and affect other variables including the total cost.

Correct Question:
Type the correct answer in the box. Use numerals instead of words. Consider this expression. [tex]\sqrt{a^2} - 7 + |b|[/tex] When a = 2 and b = -4, the value of the expression is
Answer:
[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]
Step-by-step explanation:
Given
[tex]a=2[/tex]
[tex]b = -4[/tex]
Required
Determine [tex]\sqrt{a^2} - 7 + |b|[/tex]
To solve this, we simply substitute the values of a in the given expression
[tex]\sqrt{a^2} - 7 + |b|[/tex]
[tex]\sqrt{a^2} - 7 + |b| = \sqrt{2^2} - 7 + |-4|[/tex]
Express 2² as 4
[tex]\sqrt{a^2} - 7 + |b| = \sqrt{4} - 7 + |-4|[/tex]
Express square root of 4 as 2
[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + |-4|[/tex]
[tex]|-4| = 4[/tex]
So, we have
[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + 4[/tex]
[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]
Hence, the result of the expression is -1

The age of employees at a company is an example of _____.a. quantitative datab. label datac. time series datad. categorical data
Answer:
Quantitative data
Step-by-step explanation:
When we measure something, then we can quantify them. By also making a count, we are trying to quantify a particular entity.
Now in this case, we know that age is something we can quantify or measure. By nothing the difference between the year of birth and the present year, we can simply give the number of years or simply how
old a person is.
This clearly show that we have measured the count of that entity. This makes age an example of quantitative data

In the sequence 1. 2. 3. 4. 1.2.3.4... the numbers 1.2.3.4
repeat indefinitely. What is the sum of the first 150 terms?
A. 300
B. 77
C 37
D.3
=============================================
Explanation:
The sequence {1,2,3,4,1,2,3,4...} has "1,2,3,4" repeat forever. We can say that the cycle is 4 terms before it restarts the pattern again. Because of this 4-cycle pattern, we know that 150/4 = 37.5 = 37 full cycles happen. The leftover part is of length 150-37*4 = 2.
In short we have 37 full cycles of {1,2,3,4} happening. The last leftover bit has {1,2} only
In the subsquence {1,2,3,4} its sum is 1+2+3+4 = 10. Having 37 copies of {1,2,3,4} leads to a sum of 37*10 = 370 so far.
Then we add on the last bit 1+2 = 3 to get 370+3 = 373.
Therefore, the sum of the first 150 terms is 373. I think your teacher made a typo when listing out the answer choices. Please double check to make sure.
What is the vertex of f(x) = |x + 8| – 3?
Answer:
(-8,-3)
Step-by-step explanation:
This question is similar to the vertex form of a quadratic equation, so you can think of this equation like f(x) = (x-h)+k. Using this equation, you can determine the vertex (h,k) of |x+8|-3, which is (-8,-3).

Step-by-step explanation:
Hey there!
Here;
The figure given is a Right angled triangle.
Let the unknown angle be a refrence angle.
Now,
p = 23
h = 29
In ratio of sin there is 'p' and 'h'. So, using sin ratio.
[tex] \sin( \alpha ) = \frac{p}{h} [/tex]
[tex] \sin( \alpha ) = \frac{23}{29} [/tex]

The Fairy Tale Spectacular is coming to town. Admission to the fair costs $32.50 and each ride costs $0.80. You have $50 to spend at the Fairy Tale Spectacular including admission. What is the maximum number of rides you can enjoy?
Answer:
21 rides
Step-by-step explanation:
let x = number of rides you can ride
32.50 + 0.80x [tex]\leq[/tex] 50
subtract 32.50 from both sides
0.8x [tex]\leq[/tex] 17.5
divide the left and right by 0.8
x [tex]\leq[/tex] 21.875
this means you can ride 21 times, because you can't ride a ride unless you can afford the whole cost
how to check; 32.50 + 0.8(21) is 49.30 and 80 cents more would go over your 50 dollar spending limit

Step-by-step explanation:
yikes that's hard GG bro
Answer:
The winner received 12,800 votes and the loser received 12,400.
Step-by-step explanation:
Divided the votes in half, then took 100 votes from the winner, defined W, and added 100 to the loser, defined L to give the Loser a lead of 200. Then switch 300 votes from the losers number to the winner. You'll end up with 12,800 and 12,400 and you can check by switching 300 voters from winner (12,800) to loser (12,400) to make the loser win by 200 votes. 12,800 and 12,400 also add up to 25,200.

Let L be the line with parametric equations x=2+t, y=1-t, z=1+3t.Let v=(1,2,0).Find vectors w1 and w2 such that v= w1 + w2, and such that w1 is parallel to L and w2 is perpendicular to L.
Answer:
w1 = (-1/11, 1/11, -3/11)
w2 = (12/11, 21/11, 3/11)
Step-by-step explanation:
Direction ratio of w1 = Direction ratio of L (because parallel) = K+(1, -1, 3)
Let <a,b,c> be direction ratio of w2.
Then, <a,b,c>. <1,-1,3> = 0
a-b+3c = 0
v = w1 + w2
(1, 2, 0) = k(1, -1, 3) + (a, b, c)
a + k = 1
b - K = 2
c - 3k = 0
Solving 4 equations, a = 12/11, b= 21/11, c = 3/11, k=-1/11
So, w1 = -1/11(1, -1 ,3) = (-1/11, 1/11, -3/11)
w2 = (12/11, 21/11, 3/11)
