Amanda leaned a 15-foot ladder against the top of her house so she could get on the roof, which is 12 feet from the ground.
valentinak56 [21]

If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)

a²+b²=c²

12²+b²=15²

144+b²=225

b²=81

√b²=√81

b=9

On average, Makenzie runs 4 miles in 50 minutes. How fast should she plan to run a 10-mile race if
pishuonlain [190]

Answer: A

Step-by-step explanation:

The easiest way to solve this problem would to first figure out how long it takes for Mak to run 1 mile. To do that, you would need to divide 50 by 4 which would give you 12.5. So, it takes Mak 12 and a half minutes to run 1 mile. From there, you would need to multiply 12.5 by 10 to get 125. Finally, you wold need to simplify 125 minutes to hours giving you 2 hours and 5 minutes.
