meet.
HELPP

Answers

Answer 1

Given:

Speed of Timmy = 5 miles per hour

Speed of sam = 4 miles per hour and head start of 2 miles

To find:

Where Timmy and Sam will  meet.

Solution:

Let x be the number hours they ran in marathon and y be the total distance covered.

Speed of Timmy is 5 miles per hour. So, total distance covered by Timmy in x hours is

[tex]y=5x[/tex]       ...(i)

Speed of sam is 4 miles per hour and head start of 2 miles. So, total distance covered by sam in x hours is

[tex]y=4x+2[/tex]    ...(ii)

Now, equate (i) and (ii).

[tex]5x=4x+2[/tex]

[tex]5x-4x=2[/tex]

[tex]x=2[/tex]

The value of x is 2. It means they will meet after 2 hours.

Put x=2 in (i).

[tex]y=5(2)[/tex]

[tex]y=10[/tex]

It means, they will meet at 10 miles.

does 3^4 equal the same sum as 4^3

Answers

No. 3^4 is 81 and 4^3 is 64.

Explanation:
3^4 means 3 to the 4th power. That would mean multiplying 3 by itself 4 times. Don’t get it confused with 3 x 4. Each time you multiply, the next time will multiply by itself. Basically 3 x 4 is 12, then 12 x 4 is 48, and so on.

A car can travel 480 miles on a full tank of petrol. The tank holds 60 litres. The fuel gauge shows there and 15 litres left in the tank. How many more miles can the car travel before it runs out of petrol?

Answers

Answer:

Miles= 120

Step-by-step explanation:

Giving the following information:

A car can travel 480 miles on a full tank of petrol. The tank holds 60 liters.

Miles per litre= 480 / 60

Miles per litre= 8 miles

Now, the miles that can be driven with 15 liters:

Miles= 15*8

Miles= 120

the 'b' is also called the y-intercept, the y-int is what you start of with. Example, if your parents give you $20 and you spend $5 every week, your y-int is 20

The m is the slope, so if your parents give you $20 and you spend $5 every week, your slope is -5 because your money is decreasing at a linear rate

the x is the input, so if you want to know how much money you have 2 weeks after you got $20, you would substitute x with 2, and solve to get $10
