12. To rotate CW 270 degrees, find the points of the original triangle, make the Original X value becomes the new Y value and the new X value is the inverse of the original Y value.
B) to be in the same location as the original, it would be a 360 degree rotation.
13. to rotate 180 degrees mirror the image on the X and Y axis.
B) a 360 degree rotation.

Answer:
the teacher bought 100 balloons, and 95 of them were left for the party.
Step-by-step explanation:
red balloons is given, 40.
first you find the green balloons.
<em>the number of green balloons is 3/5 the number of red balloons.</em>
3/5 * 40 = 24
so there are 24 green balloons.
next is yellow balloons.
<em>the number of green balloons is 2/3 the number of yellow balloons.</em>
24 = 2/3 * x
24 ÷ 2/3 = x
24 ÷ 2/3 = 36
there are 36 yellow balloons.
find the total balloons:
40 + 24 + 36 = 100
the teacher bought 100 balloons.
1/20 of the red balloons popped.
1/20 * 40 = 2
2 of the red balloons popped
1/12 of the green balloons popped
1/12 * 24 = 2
2 of the green balloons popped.
1/36 of the yellow balloons popped
1/36 * 36 = 1
1 yellow balloon popped
2 + 2 + 1 = 5
100 - 5 = 95
there were 95 balloons left for the party.
Answer: 90%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 9/10 as a percent, we need to find a fraction
equivalent to 9/10 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have 
.
Now, we can use cross-products to find the missing value.
So we have (9)(100) which is 900 <em>is equal</em> to (10)(n) or 10n.
So we have 900 = 10n.
Next, dividing both sides of the equation by 10, we have <em>90 = n</em>.
So, 9/10 is equal to 90/100 or 90%.
