First we need to find the total annual costs for both the plans.

In case of leasing:
Fixed monthly cost = $420
So, yearly cost = 420 x 12 = $5040
Cost per mile = $0.08

For x miles driven, the cost per year for leasing will be = 5040 + 0.08x

In case of purchasing:
Fixed yearly cost = $4600
Cost per mile = 0.10

For x miles driven, the cost per year for leasing will be = 4600 + 0.10x

We want to find for what number of miles will the cost of leasing will be no more expensive than the cost of purchasing.

So,

Cost of leasing ≤ Cost of purchasing
5040 + 0.08x ≤ 4600 + 0.10x
440 ≤ 0.02x
22000 ≤ x

Thus, if if the number of miles driven are equal to or less than 22,000 leasing will be no more expensive than purchasing.

Bill works for a large food service company. In one hour he can make 19 sandwiches or he can make 40 salads. Bill works 7 hours

wolverine [178]

Answer:

$x=216 salads$

Step-by-step explanation:

One Hour:

Salad=40

Sandwich=19

Total work time $T=7$

Generally

Time to make 30 sandwiches is

$T_s=\frac{30}{19}$

$T-s=1.6hours$

Therefore

Bill has 7-1.6 hours to make salads and can make x about of salads in

$x=(7-1.6)*40$

$x=5.4*40$

$x=216 salads$

How long would it take for a ball dropped from the top of a 484-foot building to hit the ground?

pochemuha

Answer:

First, convert the ft to standard units of meters.

1 foot = 0.3048 meters

Therefore,

484 ft = 147.5232 meters

Then, we will use the laws of motion to calculate the time:

x = 0.5 at^2

where:

x is the displacement

a is the gravity (9.8 m/sec^2)

t is the time taken

Substitute in the equation with the givens to calculate the time as follows:

147.5232 = (0.5 x 9.8) t^2

t^2 = 147.5232 / (0.5 x 9.8)

t^2 = 30.11 seconds

t = 5.49

HOPE THIS HELPED!!!!!!!XDD
