Answer:
Step-by-step explanation:
The area of a circle is expressed as
Area = πr^2
Where r = radius of the circle
π = constant = 3.14
The radius of a circle is increased from 8.00800 to 8.03803 m. This means that the original radius of the circle is 8.00800 and the new radius of the circle is 8.03803
Area of original circle =
3.14 × 8.00800^2 = 201.36212096
Area of new circle =
3.14 × 8.03803^2 = 202.87516852203
Increase in area = 202.87516852203 - 201.36212096
= 1.51304756203
Expressing the change as a percentage, it becomes
1.51304756203/201.36212096 ×100
Percentage change = 0.75 %
X - number of the adults, y - number of children;
The system is:
10 x + 6 y = 3292
x + y = 350 => y = 350 - x
----------------------
10 x + 6 * ( 350 - x ) = 3292
10 x + 2100 - 6 x = 3292
4 x = 3292 - 2100
4 x = 1192
x = 1192 : 4
x = 298
y = 350 - 298
y = 52
Answer:
There were 598 adults and 52 children at the showing.
Answer:
x +y =24
Step-by-step explanation:
(x - 8) 2 + (y + 2) 2 = 64
2x - 16 +2y+4 =64
2x + 2y =64-16
2x+2y = 48
divide both side with 2 we get
2x/2 +2y/2 =48/2
simplify
x + y =24
hence equation is x +y =24
Answer:
so you plug in the numbers you were given (-2, -1, 0, 1, 2) into the x value one at a time and you will get the other point for that pair so (3/5)^-2 and whatever number you get is the 2nd number to that ordered pair
