Answer:
b. 57
Step-by-step explanation:
AO and BO are both radii, so they're congruent, and it's an isosceles triangle. Therefore, angle A and angle B must be congruent, so we can write the equation x+x+66=180, solving for x gives us 57
Mean means to average. in order to average, add all the numbers then divide by how many numbers you have.
All these ages add up to 150. because there are 7 ages, divide by 7. this is 21.4 which can be rounded to about 21
46 + 48 + 21 + 12 + 15 + 8 = 150
150 ÷ 7= 21.4285 = 21
Answer:
![y+6=m(x+2)](https://tex.z-dn.net/?f=y%2B6%3Dm%28x%2B2%29)
where I would have to look at the table to know
.
Step-by-step explanation:
Point-slope form of a line is
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
where ![m \text{ is the slope and } (x_1,y_1) \text{ is a point on that line}](https://tex.z-dn.net/?f=m%20%5Ctext%7B%20is%20the%20slope%20and%20%7D%20%28x_1%2Cy_1%29%20%5Ctext%7B%20is%20a%20point%20on%20that%20line%7D)
You are given
.
So we know we are looking for an equation that looks like this:
![y-(-6)=m(x-(-2))](https://tex.z-dn.net/?f=y-%28-6%29%3Dm%28x-%28-2%29%29)
If you simplify this looks like:
![y+6=m(x+2)](https://tex.z-dn.net/?f=y%2B6%3Dm%28x%2B2%29)
The answer your looking for is just 5
We exclude bases for lateral area, so there are 4 sides. Each area of each of the sides can be found by 3*5. so, we have (3*5)*4, which equals 60 square meters.
