A truck driver who covers the interstate in 4 1/2hours traveling at the posted speed of 55 mph. If the speed limit is raised to

65 mph, how much time will the same trip require
Mathematics

6 0

Answer: The same trip will require 3.8 hours.

Step-by-step explanation:

Since we have given that

Time = 4\dfrac{1}{2}=\dfrac{9}{2}

Speed = 55 mph

So, distance would be

Speed\times time=55\times 4.5=247.5\ miles

If the speed limit = 65 mph

So, time will be

\dfrac{247.5}{65}=3.8\ hours

Hence, the same trip will require 3.8 hours.

What is a function in your own words?
xxTIMURxx [149]
A function is a black box, with a funnel to put numbers in, a chute where
numbers come out, a crank on the side, and some machinery inside.

You put a number in, turn the crank, and a number comes out ... usually
different from the one you put it.

If you do that enough times with enough different numbers, you can figure out
what machinery is inside.

Or, if you know what the machinery is, then when you put a number in,
you can always predict what number will come out.

For every 1 litre of water used to make a medicine, 269ml of sucrose and 47ml of saline solution are used. Express the amount of
leonid [27]

Answer:

1000 : 269 : 47

Step-by-step explanation:

A ratio is a way of comparing the value or amount of one quantity to another.

We are to find the ration of water to sucrose to saline solution, hence, it must remain in that order.

Water : Sucrose : Saline solution

The amount of water is 1 litre (1 * 1000 ml = 1000 ml)

The amount of sucrose is 269 ml

The amount of saline solution is 47 ml

Therefore, the ratio of water to sucrose to saline solution is:

W : S : SS = 1000 : 269 : 47

Since 1000, 269 and 47 have no common factors, that is the simplest form of the ratio.
