Answer:
The grade for path a is 257.1428571%
The grade for path b is 213.5%
Step-by-step explanation:
To find the grade of a slope, you take the rise over run then you multiply by 100.
Principal, P = $500
r =8% = 0.08, the interest rate
n = 1, the compounding interval
t = 6 years
The value after 6 years is
![A = P(1 + \frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20%20%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
That is,
A = $500*(1 + 0.08)⁶ = $793.44
Answer: $793.44
<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>
Answer:
His average speed is
12 km/hr
.
Step-by-step explanation:
Remember the triangle of Speed, Distance and Time. If you remember it, you'll ace these kinda questions.
I had trouble with these formulas but the triangle helped me a LOT! Anyways, let's get back to the question. The formula for average speed is pretty much the same as the formula for just speed. The average speed formula is
Average speed
=
Total Distance
Total Time
So......
48 km
4 hr
=
12 km/hr

I hope this explanation helps you!
