Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon
gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.

Assume that you heat your home with a heat pump whose heat exchanger is at Tc=2∘C, and which maintains the baseboard radiators a

elena-14-01-66 [18.8K]

Answer:

$187.61

Step-by-step explanation:

Data provided:

Temperature of the heat exchanger, Tc = 2° C = 273 + 2 = 275 K

Temperature of the base board radiators , Th=47° C = 273 + 47 = 320 K

Cost of heating the house = $1000

Coefficient of performance of the heat pump = 75% = 0.75

Now,

Actual performance = 75% of performance of heat pump

Actual performance = 0.75 × $\frac{\textup{Th}}{\textup{Th-Tc}}$

Actual performance = 0.75 × $\frac{320 K}{320-275}$

Actual performance = 0.75 × $\frac{320}{45}$

Actual performance = 5.33

Therefore, the cost = $\frac{\textup{1000}}{\textup{5.33}}$

cost = $187.61
