Answer:
144π
Step-by-step explanation:
we need the radisu
circumference formula: 2πr
2πr=24π
12=r
area formula:
πr²
12²π= 144π
im not sure but its either A Or D
Step-by-step explanation:
because the points are on that point
Answer:
x=4, y=-3. (4, -3).
Step-by-step explanation:
5x+4y=8
2x-3y=17
--------------
2(5x+4y)=2(8)
-5(2x-3y)=-5(17)
---------------------
10x+8y=16
-10x+15y=-85
-----------------
23y=-69
y=-69/23
y=-3
5x+4(-3)=8
5x-12=8
5x=8+12
5x=20
x=20/5
x=4
Answer :Hans
Here is an informal argument. Since Franz and Hans run
faster than they walk, Hans will go farther in the time that he runs
than in the equal time that he walks. Therefore he covers more
distance at a run than Franz does, since Fred covers equal distances
running and walking.
While both are walking or both are running, they will cover equal
distances. Therefore subtract this distance from the total distance.
The remaining distance is covered by Franz at a walk and by Hans at a
run, so Hans will finish first.
