Given are the seven roads (say A, B, C, D, E, F, and G) that lead to the top of a hill. We need to select a road to reach the top and then it says to select different road to get back down.
First of all, we can select any one road from seven roads. So, we have 7 ways to go to the top.
After reaching the top, this first road gets eliminated from selection and now we have only Six roads to come downhill. So, we have 6 ways to get back down.
So, total number of ways = 7 × 6 = 42 ways.
So, there are 42 different ways are there to reach the top and to get back down, if the uphill and downhill roads are different.
I think its A toooooooooooooooooooooooooooooooooo
Answer:
Plane A and QRV intersection line is QR.
Explanation:
The plane QRV contains the rectangle QRVN. This rectangle intersects the plane A in the line QR.
Plane A and QRV intersection line is QR.
If one knows a specific line in one plane (for example, two points in the plane), and this line intersects the other plane, then its point of intersection.
Thus, it is on the line of intersection for the two planes.
It is valid.
The three angles must add up to 180. So, if one is more than 90, the other two have to be less than 90.
Answer:
y=0x+-3
Step-by-step explanation:
slope intercept form is y=mx+b
m is slope
b is y-intercept
y and x are points on a coordinate plane.
