We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour
ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph
Answer:
4 loafs of bread and 6 pounds of pork.
Step-by-step explanation:
1.5(4) + 2(6) = 18
Answer:
18.85 rounded
Step-by-step explanation:
The length of an arc depends on the radius of a circle and the central angle Θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:
L / Θ = C / 2π
As circumference C = 2πr,
L / Θ = 2πr / 2π
L / Θ = r
We find out the arc length formula when multiplying this equation by Θ:
L = r * Θ
Hence, the arc length is equal to radius multiplied by the central angle (in radians).
Answer: n2 + 1
Step-by-step explanation: Make sure the 2 in the n is small. When a number is squared increased by 1 that means;
a number = a variable, I used n.
squared = In mathematics, a square is the result of multiplying a number by itself.
increased by 1, is just simply adding 1 to the squared number.
I personally think its 18, please tell me what i did wrong <span />
