Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!
The city contributed $13,500; the county contributed $27,000; and the state contributed $54,000.
Let x be the amount the city contributes. Since the county contributes twice as much as the city, the county's amount is 2x. Since the state contributes twice as much as the county, the state's amount is 2(2x) = 4x.
They total 94,500:
x+2x+4x = 94500
7x = 94500
Divide both sides by 7:
x = 13500
2x = 27000
4x = 54000
Step-by-step explanation:
Molly ran 1/4 of a mile in 1 minute, i.e.
1/4 mile : 1 minute
Multiply both sides by 4 to get time for one mile
1 mile : 4 minutes
Multiply by 4 again to get time for 4 miles
4 miles = 4*4 = 16 minutes.
So it takes Molly 16 minutes to run four miles.
