Step-by-step explanation:
63 of 130 is 48.46%
Steps to solve "what percent is 63 of 130?"
63 of 130 can be written as:
63
130
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100.
Start by writing out the formulas for perimeter and area:
P=2L+2W A=L*W
We know that A = L*W = 336 sq meters and that P=2L + 2W = 100m.
Let's solve the first equation for L: L = 336/W
Subst. this into the formula for perimeter: 2[336/W] + 2W = 100 m (given)
Now all you have to do is to solve this for W:
336/W + W = 50 becomes 336 + W^2 = 50W.
Then W^2 - 50W + 336 = 0. Using the quadratic formula, I found that
50 plus or minus sqrt (1156) 50 plus or minus 34
W = ---------------------------------------- = -------------------------------
2 2
W has to be positive. Thus, choose W = (50+34) / 2 = 42
Then L = 336 / W, or 336 / 42, or 8.
The dimensions of this rectangle are 8 by 42.
You should check these results. Does P = 2(8) + 2(42) = 100 ?
Answer:
the equation for a line is y=MX+b
m= slope(rise/run)
x=variable
b= y intercept
you would find the slope by looking at the rise over run which are both 1 and the line is negative so the slope would be negative one
you would find b by looking at where the y intercept is (y when x is zero) which is 9
y= -x+9
hope that helped
It must be an odd number because 3^7 is also shown as:
3x3x3x3x3x3x3
Which equals:2,187
2,187 is an odd number because the last number is a 7 which is odd.
