Answer:
good job its very good
Step-by-step explanation:
Multiples of 8 that are less than 60: 8,16,24,32,40,48,56,
so the 8th run is at 8.4 am ; the 10th run is at 8.20 so u only have to wait a minute.
2-I suppose it's the third answer.
3-we can't know how many cars drive by in x minutes without knowing the value of x!
<span>1st fold thickness : (2 x 0.0125) = 0.025
2nd fold : (2 x 0.025) = 0.05
3rd fold : (2 x 0.05) = 0.10
4th fold : (2 x 0.10) = 0.20
5th fold : (2 x 0.20) = 0.40
6th fold : (2 x 0.40) = 0.80</span>
Answer:

Step-by-step explanation:
step 1
Find the measure of the arc DC
we know that
The inscribed angle measures half of the arc comprising
![m\angle DBC=\frac{1}{2}[arc\ DC]](https://tex.z-dn.net/?f=m%5Cangle%20DBC%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20DC%5D)
substitute the values
![60\°=\frac{1}{2}[arc\ DC]](https://tex.z-dn.net/?f=60%5C%C2%B0%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20DC%5D)


step 2
Find the measure of arc BC
we know that
----> because the diameter BD divide the circle into two equal parts
step 3
Find the measure of angle BDC
we know that
The inscribed angle measures half of the arc comprising
![m\angle BDC=\frac{1}{2}[arc\ BC]](https://tex.z-dn.net/?f=m%5Cangle%20BDC%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20BC%5D)
substitute the values
![m\angle BDC=\frac{1}{2}[60\°]](https://tex.z-dn.net/?f=m%5Cangle%20BDC%3D%5Cfrac%7B1%7D%7B2%7D%5B60%5C%C2%B0%5D)

therefore
The triangle DBC is a right triangle ---> 60°-30°-90°
step 4
Find the measure of BC
we know that
In the right triangle DBC


substitute the values

Answer:
C, the difference is subtraction so 8 times the difference of two numbers is C
