Answer:
I am assuming it wants you to put it into digits rather than the words. If so, the answer would be 9 - (g - f)
I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
Answer:
2
Step-by-step explanation:
ist you have to lind the lcd of each fraction. that would be 10.
1/2x5/5=5/10 of the boys have brown eyes
1/5x2/2=2/10 of the boys have blue eyes
3/10=3/10 of the boys have hazel eyes
The question is asking to see how many more boys have brown eyes than hazel eyes.
Subtract 3/10 from 5/10
and that gives you 2/10
Answer:
Step-by-step explanation:
You need to analize the information given in the exercise.
By definition, there are 360 degrees in a circle.
In this case, you know that the Central angle in degrees of the given sector of the circle is the following:
And the area of that sector is this one:
Then, you need to calculate the number of sectors in that circle.
In order to do it, you have to divide 360 degrees by the central angle of that sector. So, you get:
Knowing that there are 8 sectors in the circle, you need to multiply the area of the sector given in the exercise by 8, in order to calculate the area of the circle.
Therefore, this is (Using ):
.3 (100) = moving the decimal to the right 2 times because of the two zero's in '100'
So .3 (100)= 30
