Answer:
$330
Step-by-step explanation:
A simple way to do it is to see that it already has 20 on the graph. 20 is half of 40, so that stands to reason that $165 from 20 hours turns into $330 from 40 hours since it is double the work double the money.
Complementary angles add up to 90 degrees and supplementary angles add up to 180. Straight lines such as the x-axis equate to 180. This is why angle 37 degrees is a supplementary angle because it lies as an angle on the x-axis specifically. However, the angle 63 degrees is complementary because it splits one of the quadrants. One quadrant equates to 90 degrees which is why the angle 63 degrees is complementary.
Answer:
79716.98
Step-by-step explanation:
Let L represent the number of ribbons Lily has and D be the amount of ribbons Dora has.
Since Lily has 4 fewer ribbons than Dora, the amount of ribbons Lily has can be represented as this:
L = D - 4
Because Lily has 7 ribbons, you can plug in 7 for L:
7 = D - 4
When you solve for the amount of ribbons Dora has (D), which is done by adding 4 to both sides, you get D = 11.
Therefore, Dora has 11 ribbons.
