Answer:
286.48 miles
Step-by-step explanation:
The desired arc length is 100 miles and the desired change in direction is 20 degrees. The equation that describes arc length as a function of the radius is:
Applying the given values:
A radius of 286.48 miles should be used.
Hello there!
Speed has the following formula:
S =
, or
Speed is equivalent to
Distance divided by Time.Let's check out our problems to solve for the speed.
16.)
We have 770 miles, which is a measure of distance.
We have 120 minutes, which is a measure of time.
Let's substitute our variables with these numbers.
S =
Simplify.
S = ~6.41 Mi/min
17.)
We have 2.5 mi, which is our measurement of distance.
We have 0.5 h, which is our measurement of time.
S =
Simplify.
S = 5 Mph (When you divide by 0.5 you are multiplying the numerator by 2).
18.)
We have 244 km, our distance.
We have 2.5 h, our time.
S =
Simplify.
S = 97.6 km/h
I hope this helps!
Answer:
Not sure but I think the answer is No.1
Answer:
Step-by-step explanation:
Let the width be x
- Then the length is 3x + 2
- Perimeter = 66
<u>Perimeter formula</u>
<u>Substitute values</u>
- 66 = 2(3x + 2 + x)
- 33 = 4x + 2
- 4x = 31
- x = 31/4
- x = 7.75
<u>The length is:</u>
