Answers
Answer:
D. 16.8
Step-by-step explanation:
The missing wall of the office would be; 16.8 feet long.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We are given that bedroom and office in the diagrams below are similar rectangles.
It is given that the walls on the left sides in the diagram are proportional, and the walls on the top sides in the diagram are proportional.
Threfore, we get;
x/10 = 14 /12
Solving;
x = 14/12 (10)
x = 16.8
Hence, the value of the missing wall x is 16.8 feet.

Dennis Hampton earns a straight com-
mission of 7% on sales of $5,000 or less
and 9% on sales in excess of $5,000. One
week Dennis had a gross pay of $578.
What were his total sales for that week?
Answers
Answer:
Denis's total sales that week were $ 6,422.22.
Step-by-step explanation:
Since Dennis Hampton earns a straight commission of 7% on sales of $ 5,000 or less and 9% on sales in excess of $ 5,000, if one week Dennis had a gross pay of $ 578, to determine what were his total sales for that week the following calculations must be performed:
7 = 578
100 = X
100 x 578/7 = X
57,800 / 7 = X
8,257.14 = X
9 = 578
100 = X
100 x 578/9 = X
57.800 / 9 = X
6,422.22 = X
Therefore, Denis's total sales that week were $ 6,422.22.

3. The Manhattan Island Cruise Company sold 57
tickets for its Circle-the-Island Cruise. Each adult had
to pay $22 for the cruise and each child had to pay
$10. The company's total receipts were $774. How
many children went on the cruise?
Answers
Answer:
40 children went on the cruise.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of adults on the cruise
y is the number of children on the cruise.
57 tickets were sold:
This means that [tex]x + y = 57[/tex], and since we want the number of children y, [tex]x = 57 - y[/tex]
Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.
This means that:
[tex]22x + 10y = 774[/tex]
Since [tex]x = 57 - y[/tex]
[tex]22(57 - y) + 10y = 774[/tex]
[tex]1254 - 22y + 10y = 774[/tex]
[tex]12y = 480[/tex]
[tex]y = \frac{480}{12}[/tex]
[tex]y = 40[/tex]
40 children went on the cruise.

24.. A toy company makes 40 plastic harmonicas in 30 minutes. At this
rate how long will it take to make 200 harmonicas?
Proportions
Answers
Answer:
It will take 2 and a half hours
Step-by-step explanation:
Well 40 can go into 200 5 times so you would do 5 times 30 minutes which would be 150 minutes and then you would divide it by 60 to simplify which would be 2 hours and 30 minutes. So it will take 2 and a half hours to make 200 harmonicas.
200/40 = 5
5 * 30 = 150
150/60 = 2 hours and 30 minutes
Answer:
6.7 minutes
Step-by-step explanation:
From what we know, we will have to divide. The things we are dividing are the 30 minutes it took to make the 40 plastic harmonicas and the total we need of harmonicas, which is 200. By dividing 200 by 30, we get 6.666666666666667. But, we can't have that long answer, so we need to round up. Which is when we get our quotient of 6.7 minutes. If I'm wrong, please, don't be afraid to correct me. And have a good day stranger!
Edit: This answer is wrong. I was corrected and now I know what the answer is. Please do avoid this answer. But have a good day to anyone sees this!

find the value of x in the Triangle shown below

Answers

Step-by-step explanation:
We know there are 180° in EVERY triangle. Given one angle is 58°
This triangle shown has two sides that are the same, both are 6. The value of those two sides is irrelavent, except for the fact that this is an Isosceles triangle and the angle opposite those two sides are equal.
x + x + 58 = 180
2x + 58 = 180
2x = 180 -58
2x = 122
x = 61
