Traveling at 65 mph how many feet can you travel in 22 minutes?
baherus [9]
If you are travelling at 65 mph, you have to think of it as if you are moving at a constant speed.  By dividing 65 by 60, you are calculating how many miles you are moving each minute.  In doing so, you can calculate that you are moving at 1.083333 miles each minute.  That's approximately 5720 feet per minute.  (This is calculated by multiplying 1.083333 by 5280 (the number of feet in a mile)).  5720 x 22 minutes, you will have traveled 125,840 feet.

Hope this helps!

Xin Used 20 yards of fencing to build the walls of a square a chicken coop. Used 20 yards of fencing to build the walls of a squ
Gnoma [55]

Answer:

Equation: 20=4x or x=\frac{20}{4}

Solution: x=5

Step-by-step explanation:

The formula that is used to calculate the perimeter of  a square is:

P=4s

Where "s" is the side lenght the square.

Knowing that Xin used  20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

P=20\\\\s=x

Then, you can susbtitute values into the formula P=4s:

20=4x

Finally, you must solve for "x" in order to find its value.

This is:

\frac{20}{4}=x\\\\x=5

9(y-4) -3y = 2(3y-2 need solved as fast as possible
Vlad [161]

Step-by-step explanation:

did you give us all the information ? the equating looks cut off.

so, from what I can see we have

9(y-4) - 3y = 2(3y-2)

let's try :

9y - 36 - 3y = 6y - 4

0 = 32

so, no, this can't be it. this does not have a solution. you must have cut off some additional information.
