If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:
1, 2, 3, 4, 15
10, 20, 30, 40, -75
+2, -2, +99, -99, 25
1, 5, 5, 5, 9
You need to find the measure of one interior angle. You must find the value of the exterior angle and subtract that from 180 degrees (they are supplementary:_/_).The formula to find the value of an exterior angle is 360/n where n is the amount of sides
360/9=40
subtract from 180
180-40=140
multiply 9 (there is 9 angles)
140*9=1260 degrees
Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
![s=r \theta](https://tex.z-dn.net/?f=s%3Dr%20%5Ctheta)
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that
is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find
:
![s=r\theta\\20=5\theta\\\theta=\frac{20}{5}\\\theta=4](https://tex.z-dn.net/?f=s%3Dr%5Ctheta%5C%5C20%3D5%5Ctheta%5C%5C%5Ctheta%3D%5Cfrac%7B20%7D%7B5%7D%5C%5C%5Ctheta%3D4)
This is given in radians, so
is 4 radians
D is the correct answer choice.
Answer:
Step-by-step explanation:
149x
Let's assume
Mark's present age is x
so, his age 2 years ago will be
![=(x-2)](https://tex.z-dn.net/?f=%3D%28x-2%29)
Marks age, X is six times his age 2 years ago
so, we will get equation as
