Answer:2.5
Step-by-step explanation:
Answer:
If the battery starts completely charged then after one hour it will be at 80% so at two hours it will be at 60. and there is 60 minutes in one hour so it goes down 10% in 30 minutes so it goes down 5% in 15 so it goes down 2.5% in 7.5
The answer is choice 4, they add up to 180°
Answer:
v = 25.98
Step-by-step explanation:
You could do this a number of ways. Some are much longer than others. The shortest way is to use the tangent.
Formula
Tan(theta) = opposite / adjacent
Givens
Theta = 30o
Opposite = 15 km
Adjacent = x
Solution
tan(30) = 15 / v Multiply both sides by v
v*tan(30) = 15 Divide by tan(30)
v = 15/tan(30)
tan(30) = 0.5774
v = 15 / 0.5774
v = 25.98
40 4/5 is the answer i believe. Just message me if you need help okay sweetie? :)
The estimate would be 2+3 5+2 and 6+1
so 577
you can also just round and do 250 +300= 550 +20=570
