When truckers are on long-haul drives, their driving logs must reflect their average speed. Average speed is the total distance

KengaRu [80]

Answer:

0.500 hour

Step-by-step explanation:

Givens

Distance

Total Distance on the highway = 3hr * 60 miles / hr = 180 miles
Distance in the city = 20 miles
Total Distance = 180 + 20 = 200 miles

Time

Time on the highway = 3 hours
Time in the city = x

Formula

d /t = r

Solution

Average rate = 57.14
Total Distance / Total Time = average rate
200 / (3 + x) = 57.14 Multiply both sides by 3 + x
200 = 57.14 * (3 + x) Remove the brackets
200 = 57.14*3 + 57.14x Multiply the factors on the right
200 = 171.42 + 57.14x Subtract 171.42 from both sides.
200 - 171.42 = 171.42 - 171.42 + 57.14x So the subtraction
28.58 = 57.14x Divide by 57.14
28.57/57.14 = x
x = 0.500 hour Answer

Suppose James randomly draws a card from a standard deck of 52 cards. He then places it back into the deck and draws a second ca

qwelly [4]

Answer:

1.92%

Step-by-step explanation:

The probability for first case, picking a queen out of deck, will be:

$\frac{4}{52}$

as there will be 4 queens in a deck, one of each suit.

For the second pick, the probability of picking a diamond card, will be:

$\frac{13}{52}$

here the total will remain 52 as he has replaced the first card and not kept it aside and there will be 13 cards in diamond suit (including the three face cards).

Thus the net probability for both cases will be:

$P = \frac{4}{52} * \frac{13}{52}\\ P = \frac{1}{52}\\ P = 0.01923\\P = 1.923\%\\\\P = 1.92\%$

Thus total probability for the combined two cases will be 1.92%

Plz look at pic !!!! Plz Help!!! Use proportion to solve

Answer:

It takes 26 2/3 gallons to make a 400 mile trip.

Step-by-step explanation:

This question is simply asking for the number of miles per gallon . In math, per means this is meant to be written as a fraction.

"If a trip of 270 miles required 18 gallons of gas" is actually saying "270 miles per 18 gallons." This can be written as a fraction like so: 270/18.

If we're looking for the amount of gas used for a 400 mile trip, we have the fraction: 400/g, g being the amount of gallons it took to make that trip.

Now we can set up the proportion: $\frac{270}{18} =\frac{400}{g}$
