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 g

Step-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 - 5

Step-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 = 1

y-intercept is - 6 as per graph

Then the formula is

y = x - 6

2. Points are:

(0,5 ) and (4, 1)

Slope is:

m = (1 - 5)/(4 - 0) = -4/4 = -1

y-intercept is 5 as per point

Then the formula is

y = -x + 5

3. Points are:

(-3, 1), (-1, -3)

Slope is

m = (3 - 1)/(-1 -(-3)) = 2/2 = 1

y-intercept is -5 as per graph

Then the formula is

y = x - 5
