Noelle goes east at N mph.
Karina travels west at N + 9
then their velocity between them is (N + N + 9)
After 8 hours they travel 8(2N + 9) = 232
(2N + 9) = 29
2N = 20
N = 10 mph for Noelle
N+9=19 mph for Karina
Answer:
Step-by-step explanation:
Slope = (y2 -y1)/(x2-x1)
y2 = 800, y1 = 400, x2= 4, x1= 2
Slope = (800-400)/(4-2)
= 400/2
= 200calories/hr
Answer:
B = (zx/2)+ (qx/2)
Step-by-step explanation:
x = sqrt{y}k
K is the constant of proportionality.
128 = sqrt{16}k
128 = 4k
128/4 = k
32 = k
x = sqrt{y}k
x = sqrt{36}•32
x = 6 • 32
x = 192
Find y when x = 48.
x = sqrt{y}k
48 = sqrt{y}32
48/32 = sqrt{y}
(48/32)^2 = [sqrt{y}]^2
2.25 = y
