1st to get the mpg we need to divide 96/3.2 = 30 mpg

now that we know it's 30 mpg we multiply by the gallons of gas

30 * 12.5 = 375 miles

Yuto and Lian are at train stations 1,880 kilometers apart. Yuto boards a train heading east at an average speed of 220 kilomete
ArbitrLikvidat [17]
For the answer to the question above, we'll have to use the formula for velocity which is v =<u> d
</u>                     t        and d = vt

Since the total distance is given, therefore we can get the time and it will look like this.

220t + 250t = 1880
<u>470t</u> = <u>1880
</u>470      470
the problem indicates that the train runs 250kph
Let's substitute:

d = 250(4)

the distance traveled by Lian is 1000km

Tonyas dog walking service charges a flat rate of $20 per month, plus $3 per mile that each dog is walked. beth does not charge
andreev551 [17]

Answer:

Step-by-step explanation:

given that tonya charges 20$ monthly fee and 3$ per mile of her dog-walking service.

and beth does not charge any monthly fee but charges 5$ per mile of the dog walked in.

let x be the number of miles dog has walked in a month.

the amount tonya will charge on x miles = fixed monthly fee + number of miles * charge per mile = 20+3x

and the amount beth will charge on x miles = 0+ 5*x = 5x.

we are asked to find the x-value for which beth chargeable amount = tonya chargeable amount

that is 5x = 20+3x

5x-2x = 20

2x=20

x=\frac{20}{2}   = 10

hence number of miles for which tonya and beth will charge the same amount is 10.

The energy transfer diagram represents the energy of a person diving into a pool. A wide arrow labeled gravitational potential e
Citrus2011 [14]

Answer:

The amount of thermal energy that is generated is 1000 joules.

Step-by-step explanation:

Let consider the person diving into a pool as a closed system, that is, a system with only energy interaction with the surroundings. According to the First Law of Thermodynamics, which is a generalization of the Principle of Energy Conservation, the total energy of the system is neither destroyed, nor created, only transformed. The initial gravitational potential energy is transformed into translational kinetic and thermal energy. That is to say:

U_{g} - K - Q = 0

Where:

U_{g} - Gravitational potential energy, measured in joules.

K_{tr} - Translational kinetic energy, measured in joules.

Q - Thermal energy, measured in joules.

The thermal energy is now cleared:

Q = U_{g}-K

Given that U_{g} = 8000\,J and K = 7000\,J, the amount of thermal energy that is generated is:

Q = 8000\,J - 7000\,J

Q = 1000\,J

The amount of thermal energy that is generated is 1000 joules.
