Answer:
7 / 15
Step-by-step explanation:
Fraction before painting = 5/6
Fraction left after painting = 11/30
Fracrion used = difference of the fraction before painting and fraction left after painting
Fraction used = 5/6 - 11/30
Lowest common factor of 6 and 30 = 30
5/6 - 11/30 = (25 - 11) / 30 = 14/ 30
Fraction used = 14/30 = 7/15
Answer:
D. rectangles
Step-by-step explanation:
Perpendicular is when they cross but the base isn't perpendicular
Parallel is when two lines never touch, but in the base of a prism there are lines that touch

850 * .15 = $127.50
Answer:
132
Step-by-step explanation:
Straight lines add up to 180
180-48=132
The trend of the plotted points has a positive slope, so we can eliminate -0.95 and 0. Next we need to determine how strong the correlation is from a scale of -1 to 1 where the strongest is closer to -1 or 1.
Since we cannot draw a line through all of the points, the answer cannot be 1.
Between 0.75 and 0.95, we should go with 0.95 because if we were to draw a best fit line through the points, most of them would be close to or on the line. If the answer was 0.75, the correlation would be much weaker.
So the answer is 0.95.
