Answer:
10
Step-by-step explanation:
F + V − E = 2
Where F is the number of faces, V is the number of vertices and E is the number of edges
F + 16 - 24 = 2
Combine terms
F -8 = 2
Add 8 to each side
F -8+8 =2+8
F = 10
Answer:
y = -40x+2600
Step-by-step explanation:
Writing the values as coordinate (m, s)
If after flying for 11 seconds, he is 2160 meters from her, the required coordinate is (11, 2160)
Then at 19 seconds he is 1840 meters, the required coordinate is (19, 1840)
Get the slope;
m = 2160-1840/11-19
m = 320/-8
m = -40
Substitute m = -40 and (11, 2160) into the equations;
y-y0 = m(x-x0)
y -2160 = -40(x-11)
y - 2160 = -40x+440
y = -40x+440 + 2160
y = -40x+2600
Hence the requires equation is y = -40x+2600
Answer:
The unit rate is 3!
Explanation:
To find the unit rate, you have to divided the larger number by the smaller number.
18 divided by 6 is equaled to 3, which makes the unit rate 3!
