Answer:
Pepepopo check
Step-by-step explanation:
Solución 1: 2(x) + 3(y) = 80
solución 2: 3(x) + 2(y) = 70
3(y) + 2(x) = 80
2(y) + 3(x) = 70
2y = -3x + 70
y = -3x÷2 + 35
2x + 3(-3x÷ 2+35) = 80
-5x÷2 = -25
-5x = -50
5x = 50
x-intercept: 10
x = 10
y = -3x÷ 2+35
y = -(3÷2)(10)+35 = 20
x-interpcet: 10
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480
-8y + x = 0
4y + x = 480
x-intercept (solución 2)
x = -4x + 480
x-intercept (solución 1)
4y + 180 - 8y = 0
-12y = 480
y-intercept: 40
x-intercept: 320

Answer:
V = 3579.6 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius = 10
The height is 11.4 and pi is 3.14
V = (3.14) * ( 10) ^2 * 11.4
V = 3579.6 ft^3
Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,
We know that, area of a sector is
Where, 
is central angle, r is radius.
Multiply both sides by 360 degrees.
The value of x is 60 degrees.
Therefore, the correct option is A.
