Two trains started moving at the same time, train A from Boston to New York, and train B from New York to Boston. The distance between the train stations in New York and Boston is 240 miles. The average speed of train A is 60 mph, which is 3 4 of the average speed of train B.
1. How soon will the trains meet
2. How far from New York will the trains meet?

Answers

Answer 1

Answer:

------

Step-by-step explanation:

1. The average speed of train A = 60 mph,

   The average speed of train B = 60 / 3/4 = 80 mph

Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours

2. The trains meet in 12/7 hours, each traveling at their own speed.

S = D/T, D = S*T

Therefore we can say:

12/7(60) = distance train A is from Boston = 720/7 miles

12/7(80) = distance train B is from New York = 960/7 miles

The distance from New York would = 960/7 miles

Answer:

x = 73 °

Step-by-step explanation:

A pentagon has a collective degree of 540

So to find x, you have to set up an equation:

x + 127 + 112 + 108 + 120 = 540

To solve:

Combine like terms

x + 467 = 540

Subtract 467 on both sides:

x = 540 - 467

x = 73

can you use the term parallelogram to describe a rectangle

Answers

Answer:

Yes. In order for a shape to be qualified as a parallelogram It has to have 4 main properties. Opposite sides are parallel. Opposite sides have to be congruent. The opposite angles are congruent. Consecutive angles are supplementary (adds to 180-degrees). A rectangle qualifies all of these properties for a parallelogram. Opposite sides are parallel which works for a rectangle since they never intersects with the oppposit line. Opposite sides are congruent or equal which is also true becuase when looking at any 2 opposite sides of a rectangle, its always gonna be equal. Opposite angles are congurent which is also true because their all 90 degrees all are equal. And finally consecutive angles add up to 180. Soncsuive int his case basically means the angle next to that angle but we don’t have to worry about that since all angles of a rectangle are 90 and 90+90=180 so it also DOES qualify for a parallelogram.

Answer:

a) 16.4 kmb) 79°c) 10 km

Step-by-step explanation:

Find the m∠B:

m∠B = (360° - 310°) + 50° = 100°

a)

Find AC using law of cosines:

AC = √(8² + 13² - 28*13*cos 100°) = 16.4 km (rounded)

b)

Find m∠A using law of sines:

16.4/ sin 100 = 13 / sin Am∠A = arcsin (13 sin 100 deg / 16.4) = 51° (rounded)

The bearing of C from A:

180° - (50° + 51°) = 79°

c)

Let the required distance is x:

Harriet had a remote control car every 4/15 of a second the remote control car travels 4/5 of a foot how many feet per second does the remote control car travel

Answers

Answer:

3 ft/s

Step-by-step explanation:

The rate or speed of the remote control car, v = distance/time

Now, the distance travelled by the remote control car = 4/5 of a foot = 4/5 × 1 ft = 4/5 ft and the time it takes to cover this distance is 4/15 of a second = 4/15 × 1 s = 4/15 s.

So, v = distance/time

= 4/5 ft ÷ 4/15 s

= 4/5 ft × 15/4 s

= 3 ft/s

While attending a major league baseball game, you think you can guess the
attendance within 10% of the actual value. If the announced attendance is
35,000, within what number of people would your guess have to be in order for you to support your claim?

Answers

Answer:

You would have to have guess a number larger than 31500 and smaller than 38500

Step-by-step explanation:

The answer will look something like

35000 +/- 10% (35000)

What that means is that the attendance would be smaller than 35000 or larger than 35000.

10% * 35000 = 10/100 * 35000 = 350000 / 100 = 3500

So you would have to estimate

35000 - 3500 ≤ attendance ≤35000 + 3500

31500 ≤ attendance ≤ 38500
