One electrician charges a flat fee of $55 to come to the house, $20 per
hour, and the cost of all materials. If h represents the number of hours that
the electrician spent fixing the problem, C represents the total charge, and m
represents the cost of materials, which of the following equations shows how
to determine the total fee charged?
C=20+55h+m
C=mh+55 +20
C=(55+20)h+m
C=55+20h+m
Answers
Answer:
C=55+20h+m
Step-by-step explanation:
C = flat fee + dollars/hour + material expense
C = 55 + 20h + m

Answer:
4th option: 19 units2Step-by-step explanation:
The given figure can be divided as (i) upper rectangle, (ii) lower rectangleThen,
(i) Breadth of upper rectangle = 2 units
Length of upper rectangle = 8 - 1 = 7 units
Therefore,
Area of the upper rectangle = 7 × 2 = 14 units2
(ii) Breadth of lower rectangle = 1 unit
Length of lower rectangle = 5 units
Therefore,
Area of the lower rectangle = 5 × 1 = 5 units2
Since,
Area of the figure is = Area of upper rectangle + Area of lower rectangle
= 14 units2 + 5 units2
= 19 units2 (Ans) (4th option)

Timmy is building a new website. Right after he starts, he has 2 visitors. He expects his visitors to increase according to a model he developed for his other websites growth, v(t)=10t+b, where b is the number of visitors right afte he starts building his website, t is the time since he stgarted building his website in weeks and v(t) is the nunber of total visitors after t weeks.
How many visitors does he get 4 weeks after starting to build his website?
How any new visitors does he get per week?
Answers
Answer:
He gets 42 visitors 4 weeks after starting to build his website.
He gets 10 new visitors per week.
Step-by-step explanation:
Equation for the number of visitors:
The equation for the number of visitors Timmy's new website receives after t weeks is:
[tex]v(t) = 10t + b[/tex]
In which b is the number of visitors rightly after he starts.
Timmy is building a new website. Right after he starts, he has 2 visitors.
This means that [tex]b = 2[/tex], so:
[tex]v(t) = 10t + 2[/tex]
How many visitors does he get 4 weeks after starting to build his website?
This is v(4). So
[tex]v(4) = 10(4) + 2 = 40 + 2 = 42[/tex]
He gets 42 visitors 4 weeks after starting to build his website.
How any new visitors does he get per week?
After 0 weeks:
[tex]v(0) = 10(0) + 2 = 0 + 2 = 2[/tex]
After 1 week:
[tex]v(1) = 10(1) + 2 = 10 + 2 = 12[/tex]
2 weeks:
After 2 week:
[tex]v(2) = 10(2) + 2 = 20 + 2 = 22[/tex]
22 - 12 = 12 - 2 = 10
He gets 10 new visitors per week.

Determine if lines AB and CD are parallel, perpendicular, or neither. A(5,-8), B(-2,-10), C(-6,-13), D(-2,1)
Answers
Answer: The answer is neither because the slopes are 2/7 and 7/2.
Step-by-step explanation:
While these answers look like they are perpendicular, they are not since the signs are the same. If they were perpendicular the signs would be different. Ex: 2/7 and -7/2. These points are perpendicular since their signs changes as well as being "flipped".

There were ___ children and ____ adults admitted into the park
Answers
Answer:
148 children and 140 adults were admitted.
Step-by-step explanation:
Given that the admission fee at an amusement park is $ 3.50 for children and $ 13.00 for adults and on a certain day, 288 people entered the park, and the admission fees collected totaled $ 2,338.00, to determine how many children and how many adults were admitted you must be perform the following calculation:
13 - 3.5 = 9.50
288 x 3.50 = X
1.008 = X
2338 - 1008 = 1330
1330 / 9.5 = 140
288 - 140 = 148
148 x 3.5 + 140 x 13 = X
2338 = X
Therefore, 148 children and 140 adults were admitted.

how is y=2x^2-8x+9 rewritten in vertex form.
Answers
9514 1404 393
Answer:
y = 2(x -2)^2 +1
Step-by-step explanation:
Start by factoring the leading coefficient from the x-terms.
y = 2(x^2 -4x) +9
Now identify the coefficient of x, -4, and figure half of that: -2. Square this number and add it inside the parentheses. At the same time, subtract the equivalent value outside parentheses. (The leading coefficient must be taken into account.)
y = 2(x^2 -4x +4) +9 -2(4)
Put in the desired form.
y = 2(x -2)^2 +1
This matches vertex form ...
y = a(x -h)^2 +k . . . . . . . . . vertical scale factor 'a'; vertex (h, k)

Answer: The mode.
Step-by-step explanation: The answer to this question is the mode, the answer is mode because there might be some numbers that show up the same amount of times like a different number. So there might be TWO modes :’).
Here are the definitions for mean, median, mode, and range:
Mean (the “average”) —> the sum of the numbers in the data set divided by the amount of numbers in the data set.
Median (the “middle”) —> the number in the middle of the data set, when the numbers are placed in numerical order.
Mode (the “most”) —> the number in the data set that shows up the most often.
Range —> the difference between the data set’s largest number and the data set’s smallest number.

All employees in Department A attend the sales training programme. Some employees in Department A attend the technical training programme. Some employees who attend both training programmes are in Department B. Conclusion: All employees who attend the sales training programme and who attend the technical training programme are in Department A. If the assumptions are true, is the conclusion:
a. Correct
b. Cannot be determined based on the information available
c. Incorrect
Answers
Answer:
c. Incorrect
Step-by-step explanation:
According to the third sentence in assumption "Some employees who attend both training programmes are in Department B.", it is clear that there are certain employees in department B, who are attending both the training. Hence, all the employees who attend the sales training programme and who attend the technical training programme are not in Department A. Some of them are in department B as well.
Therefore, the conclusion is not correct and the final answer is:
c. Incorrect
