Answer:
Oliver completed his training work in 50.25 hours
Step-by-step explanation:
we know that
1 day= 24 hours
1 hour=60 minutes
we have
2 days, 2 h, and 15 min
<u><em>Convert days to hours</em></u>
2 days=2(24)=48 hours
<u><em>Convert minutes to hour</em></u>
15 min=15(1/60)=1/4=0.25 h
so
2 days, 2 h, and 15 min=(48)+(2)+(0.25)=50.25 h
therefore
Oliver completed his training work in 50.25 hours
Answer:
12.57555 rounded to 12.5756
Step-by-step explanation:
34'=34*1/60=0.56°
56''=56/1/3600=0.01555°
12°+0.56°+0.01555°=12.57555°
1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1
Answer: The length of the base of the triangle is 16 inches.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula
Area of a triangle (A) = base x height x 1/2
Replacing with the values given:
42 = b (5 1/4) 1/2
Solving for b (lenght of the base)
42 / (5 1/4) 1/2 = b
16 in = b
The length of the base of the triangle is 16 inches.
Feel free to ask for more if needed or if you did not understand something.
the base of the ladder is 18ft away from the wall
