Use this formula:
original amount - new amount
———————————————-
original amount
you just plug in the numbers in this formula now and solve
20-11 9
——— = —- = 0.45
20 20
multiply 0.45 by 100 to convert it into a percent
0.45 * 100 = 45
The answer is 45% !!
Answer:
The coordinates of the focus of the parabola is:
Step-by-step explanation:
We know that for any general equation of the parabola of the type:
The focus of the parabola is given by:
Focus= (h,k+p)
Here we are given a equation of the parabola as:
On changing the equation to general form as follows:
Hence, we have:
Hence,
Hence, focus is:
For the points you've given, the correct answer is not listed! One way to solve the problem is just to use a graph -- the points are not far away from the origin, and they have whole number coordinates. (See graph.)
Slopt = "rise" / "run" so to get from (2, 2) to (4, 3), you "rise" +1 and "run" +2. The slope is 1/2.
If the points are (2, 2) and (4, 3), then the slope would be 2.
You can always use a formula to find the slope:
which tells the slope of a line joining points
and
.
The formula says
Slope = (second y minus first y) / (second x minus first x)
It always works unless
, in which case the line is vertical and has NO defined slope.
<h2>
Number of cups of corn starch required for the recipe = 12.5</h2>
Step-by-step explanation:
Total starch required = 5 cups
Measurement of measuring cup = 2/5 cups.
Number of cups required = Total starch required ÷ Measurement of measuring cup
Number of cups of corn starch required for the recipe = 12.5
