Answer:
Step-by-step explanation:
rise / run is another way of expressing the tangent.
So when you are told that the rise over run is 35% you mean the rise is 35% of the run.
Another way of expressing this is by saying Tan(theta) = 0.35
theta = tan-1(0.35)
theta = 19.29 degrees.
The answer is A. You can reason this out. 19 degrees is the smallest answer. If it was any larger, do you think an 18 wheeler would be able to make the grade? Likely not.
Box 1 = 6 & 3/8 kilograms.
Box 2 = 7 & 2/8 kilograms.
6 & 3/8 + 7 &2/8 = 13 & 5/8 kilograms.
Therefore the combined weight of the boxes are 13 & 5/8 kilograms.
Its decagon. cause it has 10 corners.
Answer:
68.2 miles per hour
Step-by-step explanation:
Speed limit = 110 kilometers per hour
1 kilometer = 0.62 miles
110 kilometers = x miles
Cross product
1*x = 0.62*110
x = 68.2 miles
Cesar should drive at 68.2 miles per hour to avoid a speeding ticket
110 kilometers per hour = 68.2 miles per hour
First we will find the interest on:
P = $235 principal
t = 2 years
r = 0.1415 annual rate
A = future value
I = A - P the interest
A = P(1 + r)^t
A = 235(1 + 0.1415)^2
A = $306.21
I = A - P
I = $306.21 - $235
I = $71.21
the interest was $71.21.
Next lets find the lifetime cost value:
Lifetime cost value = 306.21 + 5*1.56*52 + 5*0.78*52 = $914.61 (considering that 1 year = 52 weeks)
Now lets find the percentage what percentage the interest is of the lifetime cost:
(71.21/914.61)*100 = 7.79%
