A freight train is carrying goods across the country. The number of gallons of fuel it has used varies directly with the distanc

Maru [420]

Answer:

0.125 miles per gallon.

Step-by-step explanation:

After 200 gallons used the freight train has traveled 25 miles. This means that we need to divide both sides by 200 to get a singular gallon's worth of miles traveled. 200/200 is 1, and 25/200 is 0.125.

IF it were how many gallons per mile, you would divide both answers by 25 resulting in 8 gallons per mile.

The volume of gas in a container at a constant temperature varies inversely as the pressure. If the volume is 32 cubic centimete

finlep [7]

Answer:

The new pressure is 4.27 pounds

Step-by-step explanation:

In this question, we have the volume varying inversely as the pressure;

Firstly, let's say the volume is V and the pressure is P

Mathematically;

V ∝ 1/P

Let us insert a constant of proportionality K

⇒ VP = K

Let's calculate the value of K

K = 32 $cm^{3}$ × 8 = 256 $cm^{3} pounds$

Now in the second scenario, pressure is unknown but we know the volume to be 60 $cm^{3}$

Recalling; VP = K

P = K/V = 256 $cm^{3} pounds$ /60 $cm^{3}$ = 4.27 pounds

Ilia_Sergeevich [38]

Answer:

The country's debt is $ 48,543.68 per person.

Step-by-step explanation:

Given that at the end of a year, the gross debt of a country stood at about $ 15 trillion, to determine this amount in dollars per person, assuming that the population of the country is about 309 million, the following calculation must be done:

15 trillion = 15,000,000,000,000

15,000,000,000,000 / 309,000,000 = X

15,000,000 / 309 = X

48,543.68 = X

Therefore, the country's debt is $ 48,543.68 per person.

Aleks04 [339]

Answer: 3:1

Step-by-step explanation:

Since the jewellery shops sell 240 necklaces in a month and 180 of the necklaces were sold via the shop's website, this means that (240 - 180) = 60 necklaces were sold in a high street shop.

Therefore, the ratio of online sales to shop sales will be:

= 180 / 60

= 3 / 1

= 3:1
