PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?

Answers

Answer:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.

Step-by-step explanation:

The given is,

One train travels at an average speed of 80 km/hr

The other travels at an average speed of 70 km/hr

Step:1

Formula to calculate the distance traveled by two trains,

Distance traveled by two trains = (Rate of speed of train one +

Rate of speed of other train) × Time

From the given the above equation becomes,

Let, h = Time taken to each the distance

50 = ( 80 + 70 ) h

50 = (150) h

= 0.3333 hours

= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )

h = 20 minutes

Step:2

Check for solution,

From equation (1),

50 = ( 80+70 ) (0.3333)

50 = (150)(0.3333)

50 = 50

Result:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Hannah buys 3 pairs of shoes for $x each. She uses a $10 off coupon. She
spent a total of $35. Write an equation that can be used to find the cost of each pair of shoes.

Answers

Answer:

$15 per pair

Step-by-step explanation:

We know that the total amount of money she spent on the shoes (without discount) is 3x. Since she used a $10 off coupon, the money she spent is 3x - 10, since $10 off means - 10. And this amount equals $35:

[tex]3x - 10 = 35\\3x = 45\\x = 45/3 \\x = 15[/tex]

The table shows the number of bottles of different kinds of juice sold at a cafeteria on Monday.

If the cafeteria has 80 customers on Tuesday, which prediction for Tuesday is NOT supported by the data in the table?
Pls answer ASAP

Answers

Answer:C

First you need to add up everything to find out the amount of costumers more Monday. You will get 40. Then you would have to multiply 40 by 2 to get 80 which is the total amount of costumers for Tuesday. This means that you have to double the amount of everything on the table to find out how much of each item was sold. The questions says which is NOT supported by the table. When you do the math you see that everything is accurate except C because the number of apple juice sold on Tuesday is 22 and the number of cranberry juice sold on Tuesday is 14. 22 is not 6 times more than 14 which makes C the correct answer.

A triangle has angles measuring 43° and 62°. What is the measure of the triangle's third angle?

Answers

Answer:

75 degrees

Step-by-step explanation:

I know the measure of the triangle's third angle is 75 degrees because all the angles of a triangle add up to 180 degrees. So, I did 180-62-43 and got 75. So, in order for this triangle to be true, the third triangle would have to be 75 degrees.

To check: 43 degrees+ 62 degrees+ 75 degrees = 180 degrees.

The answer is 75 degrees

After taking $10,000 of depreciation on the truck, he sold it for $16,000. What is Hank's gain or loss on this sale? It is believed by some economists that by and large, the North American market (primarily the U.S.) for breakfast cereals reflects a monopolistically competitive structure with extensive product differentiation, significant levels of advertising expenditure, and brand-building exercises undertaken by firms , and freedom of entry and exit in the long run. Companies such as Kellogg's, General Mills, and Post dominate this market, but other players exist as well; however, there are seemingly endless varieties of breakfast cereals and each variant often resembles a single brand-for example, Kellogg's Froot Loops is unique and so is General Mill's 'Cheerios'. Because of such strong levels of product differerentiation and high marketing costs associated with each brand, these companies operate with excess capacity,meaning that their output levels do not reach the minimum point of the LAC (Long-Run Average Cost) curve. To explain this phenomenon, free entry and exit of firms also ensures that there is active price competition among cereal manufacturers, although there may not be much interdependence between prices of rival firms due to product differentiation. Therefore, when prices fall due to free entry of firms, firms also find it very hard to realize economies of scale by producing more cereal of the same type. Based on what you have understood about monopolistic competition, would you support the argument that the breakfast cereal market is monopolistically competitive ? You may justify your own point of view in detail. If you do not agree that this market is monopolistically competitive, explain why you think this is so. manufactures one product called Nananera.
