This is a positive increase

You need to find the difference between 50 and 76 which is 26.
Then you do 26/50 which is 0.52. Multiply 0.52 by 100 and that leaves you with 52.

The percentage increase is 52%.

Hope this helps x

Answer:

<h3>50 is the old value and 76 is the new value. In this case we have a positive change (increase) of 52 percent because the new value is greater than the old value.</h3>

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!

0 = -1/14 x^2 + 4x +5<br><br> I need to solve for x but I don't get it, PLEASE EXPLAIN AND HELP!!
MariettaO [177]
Any time you have a fraction within an equation, multiply the entire equation by the denominator to clear the fraction. Since the lead term is negative, we can multiply that away as well
(-14) (0=-1/14x²+4x+5)      [now distribute]

0=x²-56x+70      [try to factor into binomials first]
Since 70 only has prime factors of 2·5·7, there is no combination which equals (-56). Use the quadratic formula, or complete the square. I'll use quadratic:

x=<u>-b+/-√(b²-4ac)</u>
            2a
a=1, b=(-56), c=70

x= <u>-(-56)+/- √((-56)²-4(1)(70)</u>
                  2(1)
x= <u>56+/- √(3136-280)
</u>               2
<u />x=<u>56+/-√(2856)</u>
             2
x=<u>56+/-√(2³·3·119)</u>
               2

x=<u>56+/-2√(714)</u>
             2

x=28+√714; x=28-√714
