KFC sells whole chicken dinners for 12 and half chicken dinners for 8. Yesterday it sold a total of 400 dinners and took in 4200
SVEN [57.7K]

Answer:

150 half chicken and 250 full chicken

Step-by-step explanation:

Represent whole chicken with w and half chicken with h.

So, we have:

Total = 400

Which implies that:

w + h = 400

Also:

Amount =\$4200

Which implies that:

12w + 8h = 4200

So, we are to solve for h and w from:

w + h = 400

12w + 8h = 4200

Make h the subject in the first equation

h = 400 - w

Substitute 400 - w for h in the second equation

12w + 8(400 - w) = 4200

12w -8w + 3200 = 4200

12w -8w =- 3200 + 4200

4w =1000

w = 250

Recall that:

h = 400 - w

h = 400 - 250

h =150

If the flare is launched with an initial velocity of 144 feet per second, find the height after 2 seconds. The answer is not 288
salantis [7]

Answer:

The height = 223.6 ft

Step-by-step explanation:

∵ Initial velocity (u) = 144 ft/sec

∵ t = 2 sec

∵ a = - 32.2 ft/sec²

∵ h = ut + 1/2 at²

∴ h = 144(2) +1/2 (-32.2 × 4) = 288 + 1/2( -128.8) = 223.6 ft
