A bicycle is traveling at 70 miles per hour how many feet will it cover in 25 seconds round your answer to the nearest tenth of
gulaghasi [49]

Hey there! I'm happy to help!

We see that the bike travels at 70 miles per hour. There are 5280 feet in one mile, so 70 miles is 369600 (70×5280).

We have 369600 in 1 hour, which is the same as 60 minutes. There are 60 seconds in a minute, so this means that there are 3600 seconds in an hour (60×60).

We have 369600 for 3600 seconds. We want to see how far the bike travels in one second, we simply divide 369600 by 3600.

369600÷3600≈102 2/3.

Now we multiply this by 25 for 25 seconds.

102 2/3×25=2566.7 (rounded to nearest tenth of a foot)

Therefore, in 25 seconds, the bike will have traveled 2566.7 feet.

Have a wonderful day! :D

What is the area of the rectangle with the given dimensions? *
exis [7]

Given:

The dimensions of a rectangle are 2x-5 and 3x+3.

To find:

The expression that represents the area of the rectangle in simplest terms.

Solution:

Area of a rectangle is:

Area=Length\times Width

The dimensions of a rectangle are 2x-5 and 3x+3. So, the area of the given rectangle is:

Area=(2x-5)\times (3x+3)

Area=2x(3x)+2x(3)-5(3x)-5(3)

Area=6x^2+6x-15x-15

Area=6x^2-9x-15

Therefore, the correct option is F, i.e., 6x^2-9x-15.
