Depending whether you need to use the Pythagorean theorem or sine both answers are there, Pythagorean is 12.1 and sin=12
The answer is A.
5(10)+13(14)=232
50 + 182 =232
12(10)+7(14)=218
120 + 98 =218
Answer:
20%
Step-by-step explanation:
You could do it without reduction
(3/15) * 100 = 3*100/15 = 300/15 = 20 = 20%
Or you could do it by reduction
3/15 = (3÷3) / (15 ÷3) * 100 = (1/5)*100 = 20%
Answer:
40 seconds
Step-by-step explanation:
120/12 = 10
10*4 = 40
THEREFORE 40 seconds to walk 120 feet at that speed
