Answer:
13
Step-by-step explanation:
The theorem is that for a line bisecting two parallel lines, the oposite angles are equal. Hence, you can formulate the equation 4x+18 = 7x-21, which solves to 13.
Answer:
Step-by-step explanation:
present value of dividend for three years =
2.50 x 1.2 / 1.15 + 2.5 x 1.2² / 1.15² + 2.5 x 1.2³ / 1.15³
= 2.6087 + 2.722 + 2.84
= 8.17
present value of future cash flow after three years
= 2.5 x 1.2³ x 1.08 / .15 - .08
66.65
present value
= 66.65 / 1.15³ = 43.823
Total present value = 43.823 + 8.17
= 52 approx .
After 10 minutes, he's 40 miles away. After 22 minute, he's 34 miles away. Therefore, in those 12 minutes between, he covered 6 miles. We can make a ratio out of this: 6/12 = 0.5, so he is walking at a rate of 0.5 mi/min (miles per minute). Finally, we can set x/90 equal to 0.5/1 because he is walking at the same rate the entire time. Cross multiply to solve for x. Finally, you get that he had to travel 45 miles in 90 minutes, so his home is 45 miles away from his grandmother's.
X=111
A 7 sided shape all the interior angles should add to 900 so if you add all the angles given you get 789 then subtract that from 900
