The answer is d your welcome
5/6 - 4/5 25/30 - 24/30 = 1/30 half of 60 is 30 + 20 = 50 so d.
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The distance is
.
- The time is
.
2. Therefore, you must divide the distance by the time to calculate the average speed:
![V=d/t\\ V=112miles/12hours\\ V=9.33 miles/hour](https://tex.z-dn.net/?f=%20V%3Dd%2Ft%5C%5C%20V%3D112miles%2F12hours%5C%5C%20V%3D9.33%20miles%2Fhour%20)
The answer is: ![9.33miles/hour](https://tex.z-dn.net/?f=%209.33miles%2Fhour%20)
Answer:
B
Step-by-step explanation:
You need to find x, so you'll have to use cos in this case, because x is adjacent to the only angle you have.
So, you'll get:
cos 30 = x/10 (adjacent/hypotenuse)
Rearrange the equation for x:
x = cos 30 x 10
<em>*Since the options you have are in exact values, you can't use a calculator just to find x. </em>
Cos 30 in exact values is √3/2
<em>*you can either memorise these values or learn the trig triangles. either way, just know the exact values for sin, cos and tan for 30, 60 and 90 degrees</em>
So to find x:
x = √3/2 x 10
x = 5√3

Approximated (3.14): 15.42 km
Step-by-step explanation:
Hello!
A semicircle's perimeter can be found using the formula: ![P = \pi r + 2r](https://tex.z-dn.net/?f=P%20%3D%20%5Cpi%20r%20%2B%202r)
We can plug in the values to solve for the perimeter.
<h3>Solve</h3>
In terms of Pi, it is
,
Exact value of Pi, it is 15.42477
Approximation of Pi (3.14), it is = 15.42
