It is 236. Happy to help (:
The answer is C
adult: x
student: y
x+y=120
6x+4y=560
Rearrange the equation so the left side starts out as y =
5x + 3y = -4
3y = -5x - 4
y = (-5/3)x - (4/3)
the slope is in front of the x and the y-intercept iis the other number
slope is -5/3
y-interxept = -4/3
45w = 500 + 85
45w = 585
w = 585/45
w = 13 <=== 13 weeks
Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume of cylinder = πr^2h
Where
π is a constant whose value is 3.14.
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
The radius of a cylinder is 7.8*10^-4 m.
The height of the cylinder is 3.4*10^-2.
Therefore,
Volume of cylinder =
3.14 × (7.8*10^-4)^2 × 3.4*10^-2
= 3.14 × 60.8*10^-8 × 3.4*10^-2
= 649.52784 × 10^- 10 m^2
