The Gotemba walking trail up Mount Fuji is about 9 kilometres (km) long. Walkers need to return from the 18 km walk by 8 pm. Tos

hi estimates that he can walk up the mountain at 1.5 kilometres per hour on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi's estimated speeds, what is the latest time he can begin his walk so that he can return by 8 pm?

Answer:

He must start his journey by 11 AM

Step-by-step explanation:

Speed of Toshi while walking up the mountains is 1.5 kilometres per hour

Speed of Toshi while walking down  the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour

Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours

Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours

He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance

Thus, He must start his journey by 11 AM

Please answer quickly this is due today and I just can’t figure it all out!!
Bumek [7]

Answer:

A. You may set the variables in either order. But for argument sake, let's set as follows:

x = Amount of bookshelves

y = Amount of tables

B. Because of the amount of things you need to make, the following is an inequality using those variables.

x + y > 25

Plus you can determine a second inequality based on the amount of money that you have to spend.

20x + 45y < 675

Finally you may also add in that each value must be greater than or equal to zero, since they cannot have negative tables.

C. By solving the system and looking at basic constraints when graphed, you can see the feasible region has 4 vertices.

(0,0)

(18, 7)

(0, 15)

(33.75, 0) or (33, 0) if you insist on rounding.

Step-by-step explanation: Good luck and hope this helps :)

Find the probability of rolling a sum of 6 with two dice?
34kurt

Answer: 5/36

Step-by-step explanation:

There are 3 ways to do this

Get a 1 and a 5

Get a 2 and a 4

Or get two 3's.

There are two ways to get a 1 and a 5

1 first and 5 second or

5 first and 1 second

The same goes for the 2 and the 4, but NOT for the two 3s.

We have 5 ways to get a sum of 6

What is the probability of one of them happening?

1/6 x 1/6 = 1/36

1/36 chance of one occuring

1/36 x 5 = 5/36 chance of getting a sum of 6 (as there are 5 ways to do so)

Can someone help me PLZ! I keep posting the same question and no ones helping me :((((((((((((
Bond [772]

Answer:

250 - 20x=y

Step-by-step explanation:

As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter (x) will be used for the time, and (y) for the savings.

Steve's saving would be equal to his initial value, minus his expense, in essence;

250 - 20x=y

The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.
