Answer:
2 PI
Step-by-step explanation:
so the segment appears to be 1/4th of the circle, being shown by the pi/2 as displayed. Thus, we can solve for the circumfrence and divide that answer by 4. since 2*pi*r is the way to calculate this problem, it would be 2 times pi times 4, giving us the whole circumfrence of 8pi. Divide that by 4, and you have the solution of 2 pi
5.2
What is 1/5? 0.2, it's easier to type in a decimal than a fraction. So if you type in 0.2 x 26 in your calculator you'll get 5.2.
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
Answer:
Condition 1:
four times the sum of X and Y = 4(X + Y)
Condition 2:
the sum of four times X and Y= 4X + Y
In condition 1, both the variables are first added and then multiplied by four. This can be simplified as:
4X +4Y
I condition 2, only the variable X is multiplied with 4 and then added to Y.
With positive integers, condition 1 will always give a greater value.
With negative integers, condition 2 will have greater value.
I hope it will help you!
