Answer:
The answer is D. 18 + (-7)
Answer:
C. 30 ft
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
When we draw out a picture, we should see that we use the Pythagorean Theorem to help solve our missing height:
10² + b² = 32²
b² = 32² - 10²
b = √924
b = 2√231 or 30.3974
Round that to 30 feet.
4/5 mile in 1/2 hour.
1/2 * 2 = 1
4/5 * 2 = 8/5
8/5 miles per hour or 1.6 miles per hour
