Answer:
1. 4 as that is when he is closest.
2. 3 is when he is waiting as the graph is horizontal showing no movement
3. 4 would change as that is showing his pace walking home if it increased the slope would become steep but if it decreased it would level out more.
Step-by-step explanation:
Answer:
Sedan: 4 passengers
Minivan: 6 passengers
Step-by-step explanation:
We can write the following system of equations:
, where
represents the number of people a sedan can seat and
represents the number of people a minivan can seat.
Subtracting the first equation from the second, we have:
![2s+2m-(2s+1m)=20-14,\\\\m=6](https://tex.z-dn.net/?f=2s%2B2m-%282s%2B1m%29%3D20-14%2C%5C%5C%5C%5Cm%3D6)
Now plug in
in any of the equations to solve for
:
![2s+1(6)=14, \\2s=8, \\s=4](https://tex.z-dn.net/?f=2s%2B1%286%29%3D14%2C%20%5C%5C2s%3D8%2C%20%5C%5Cs%3D4)
Verify that the solution pair
works:
![2(4)+1(6)=14\: \checkmark \\2(4)+2(6)=20 \: \checkmark](https://tex.z-dn.net/?f=2%284%29%2B1%286%29%3D14%5C%3A%20%5Ccheckmark%20%5C%5C2%284%29%2B2%286%29%3D20%20%5C%3A%20%5Ccheckmark)
Therefore, a sedan can hold 4 passengers and a minivan can hold 6 passengers.
Answer:
4th option
Step-by-step explanation:
The chord- chord angle 67.5° is half the sum of the arcs intercepted by the angle and its vertical angle, that is
67.5 =
(x + 90)
Answer:
96 * 144 - 168 * 42
Step-by-step explanation:
So the area of the wall is 96 * 144
And the area of the tiled part is 168 * 42
So it would be 96 * 144 - 168 * 42
