Lets begin with an example.
You have 100 apples. 40 % of your apples are 40. Sounds complicated?
Here is the calculation in words, number of apples times 40 percentage.
By equation: 100 * 40/100= 40. Simple huh?
% symbol represents 100.
% 15 equals 15/100; 20% is equal to 20/100 or 1/5 in a simplified way.
Have a look to question. 40 iris at last year, 15 % MORE iris this year.
What is the 15 % of 40 iris? That's the question at the end.
Recall apple example at the beginning.
40 iris * 15/100 = 6.
So, there are 6 MORE iris blooms this year. This year Savanna has totally 46 iris.
5/(x^2-4)+2/x=2/(x-2) if we factor the leading denominator, it is a "difference of squares" of the form (a^2-b^2) which always factors to (a-b)(a+b) so we have:
5/((x-2)(x+2))+2/x=2/(x-2), to add/subtract fractions we need a common denominator, so in this case we need a common denominator of x(x-2)(x+2) so
5(x)+2(x+2)(x-2)=2(x)(x+2), perform indicated operations...
5x+2(x^2-4)=2x(x+2)
5x+2x^2-8=2x^2+4x subtract 2x from both sides
5x-8=4x subtract 4x from both sides
x-8=0 add 8 to both sides
x=8
check...
5/(x^2-4)+2/x=2/(x-2) when x=8 so
5/(64-4)+2/8=2/(8-2)
5/60+1/4=2/6
5/60+15/60=20/60
20/60=20/60
Answer:
Step-by-step explanation:
the shape can be divided into two semi-circles of radius 5 cm and (11x10) cm rectangle
so,
area = (2 x 0.5x pi x 5x 5) + (11x10) = 188.5 cm sq

58.6 kilometer/hour = 97666.666667 centimeter/minute
Step-by-step explanation:
How to Convert Centimeter/minute to Kilometer/hour
1 cm/min = 0.0006 km/h
1 km/h = 1666.6666666667 cm/min
Example: convert 15 cm/min to km/h:
15 cm/min = 15 × 0.0006 km/h = 0.009 km/h
