A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm 3 , what is the mass of the gas in the tube in mg?
Answers
Answer:
0.125214 gStep-by-step explanation:
we know that density is given as
density=mass/volume
the volume of the cylinder
v= πr^2h
v=3.142*1.5^2*14.4
v=3.142*2.25*14.4
v=101.8cm^3
Given that density =0.00123g/cm^3
mass= density*volume
masss= 0.00123*101.8
mass= 0.125214 g

Quan makes $72 a day as an Uber driver, plus $8 for each client he has. If
Quan typically makes $104 a day. How many clients does he usually have
Answers
Answer:
Quan usually has 4 clients
Step-by-step explanation:
Working backward at math is to start with the final situation and work back one step at a time to get to the beginning.
We know Quan makes $104 a day, including his $72 fixed rate plus an $8 rate per client.
Subtracting the total and the fixed rate, we can find the variable part of his earnings.
$104 - $72 = $32
Quan usually makes $32 for the variable rate at $8 per client, thus he usually has $32 / $8 =4 clients.
Quan usually has 4 clients

Answer:
y = x - 6y = -x + 5y = x - 5Step-by-step explanation:
Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept
1. Points are:
(2, -4) and (4, -2)Slope is:
m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1y-intercept is - 6 as per graph
Then the formula is
y = x - 62. Points are:
(0,5 ) and (4, 1)Slope is:
m = (1 - 5)/(4 - 0) = -4/4 = -1y-intercept is 5 as per point
Then the formula is
y = -x + 53. Points are:
(-3, 1), (-1, -3)Slope is
m = (3 - 1)/(-1 -(-3)) = 2/2 = 1y-intercept is -5 as per graph
