2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.

The easiest way to answer this question is by going through each answer one by one:
14:6 = 28:18
28 <span>÷ 14 = 2
</span>18 <span>÷ 6 = 3
</span>Since both numbers were multiplied by different numbers, we can establish that this is not a true proportion.
42:7 = 6:2
42 ÷ 7 = 6
7 ÷ 7 = 1
42:7 = 6:1
By dividing both numbers by the same number, we can establish that the answer is wrong.
2:3 = 3:2
This is obviously wrong. That is because, in ratios, the order counts. So the first 3 is more than the first 2, therefore the second number on the other side of the ratio should be more than the first.
3:5 = 12:20
12 <span>÷ 3 = 4
</span>20 <span>÷ 5 = 4
</span>Since both numbers were multiplied by the same number, this is a true proportion.
The answer is D.
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , thus
A(4, - 1 ) → A'(- 4, - 1 )
B(3, - 3 ) → B'(- 3, - 3 )
C(0, 2 ) → C'(0, 2 )
Remember, to the find the volume, you have to do length*width*height.
So it would be 7/4 * 3/2 * 1/2
To answer this, multiply all the numerators together, and multiply all the denominator together.
This would be:
21/16
So the answer is 21/16 cm^3 or 1.3125 cm^3.
