Answer:
$110
Step-by-step explanation:
The computation is shown below:
Provided that
Number of desk purchased Fund Left $
0 700
1 590
2 480
3 370
4 260
5 150
6 40
Now the Fund decreased while purchasing is
= 5 desks - 2 desks
= 3 desks
i.e
= $480 - $150
= $330
Now the amount of money left for decreased the desk fund is


= $110
Answer:
x = 9; y = 12; u = 24; v = 32
Step-by-step explanation:
The corresponding sides of similar triangles are in the same ratio to each other.
3/5 = (3 + x)/20 Multiply each side by 20
20×3/5 = 3 + x
12 = 3 + x Subtract 3 from each side
x = 9
=====
4/5 = (4 + y)/20 Multiply each side by 20
20×4/5 = 4 + y
16 = 4 + y Subtract 4 from each side
y = 12
=====
3/5 = (3 + x + u)/60 Multiply each side by 60
60×3/5 = 3 + x + u
36 = 3 + x + u Insert the value of x
36 = 3 + 9 + u
36 = 12 + u Subtract 12 from each side
u = 24
=====
4/5 = (4 + y + v)/60 Multiply each side by 60
60×4/5 = 4 + y + v
48 = 4 + y + v Insert the value of y
48 = 4 + 12 + v
48 = 16 + v Subtract 16 from each side
v = 32
x = 9; y = 12; u = 24; v = 32
Answer:
1.9( j + 8 + j)
2. 9(4 j) + 9 (8 + j)
2. 45 j + 72
Step-by-step explanation:
1.nine times, open parentheses four times j plus eight plus j
2. 9(5 j + 8)=
Sarah had a total amount of 45 teeth meaning that her neighbor gave Sarah $225.
<h3>
Solution (a):</h3>
- Area of rectangle = LB
- => Area of rectangle = 18 x 36
- => Area of rectangle = 648 in²
<h3>
</h3><h3>
Solution (b):</h3>
<u>Since the two triangles are equal (as said in the question):</u>
- => Area of triangles: 2(1/2 x 6 x 18)
- => Area of triangles: 6 x 18
- => Area of triangles: 108 in²
<h3 /><h3>Solution (c):</h3>
<u>Subtract the area of the triangles from the area of the rectangle.</u>
- 648 - 108 = Area of trapezoid
- => 540 in² = Area of trapezoid
The answer is d. I believe it was for mine
