Answer:
4. false 1 is nor prime nor composite
We know that
see the picture to better understand the problem
in the right triangle ABC
Applying the Pythagoras Theorem
AB²=BC²+AC²-------> BC²=AB²-AC²
AB=8 ft
AC=4 ft
BC²=8²-4²-----> BC²=48--------> BC=√48-------> BC=6.93 ft
the answer is6.93 ft
Answer:
15 miles
Step-by-step explanation:
Steve runs 3.5 miles in 30 minutes (0.5 hours). So his speed is:
r = 3.5 mi / 0.5 h
r = 7 mi/h
If his rate increases to 7.5 mi/h, the distance he runs in 2 hours is:
d = 7.5 mi/h × 2 h
d = 15 mi
