Step-by-step explanation:

Your goal is to isolate x, so your first step is to subtract by 3 on both sides. That leaves you with the equation 8x=24. Divide by 8 on both sides (since x is being mutliplied b 8) and you get x=3

An employee earns $195 for 15 hours of work. Assuming he is paid by the hour, how much will the employee earn in 8 hours?

vampirchik [111]

Answer:

$104

Step-by-step explanation:

First, find the employee’s hourly rate. You can do this by dividing the total amount earned by the total hours worked. $\frac{195}{15}=13$
Now that you know that the employee’s hourly rate is $13 per hour, you can multiply the hourly rate by the number of hours. $13*8=104$

a film canister in the shape of a cylinder has a height of 8 centimeters and a volume of the film canister. write an equation fo

uranmaximum [27]

Answer:

Part a) The equation for the volume of the film canister is

$32\pi=\pi r^{2}(8)$

Part b) The radius of the film canister is $2\ cm$

Step-by-step explanation:

<u><em>The complete question is</em></u>

A film canister in the shape of a cylinder has a height of 8 centimeters and a volume of 32π cubic centimeters.

a. Write an equation for the volume of the film canister.

b. What is the radius of the film canister?

Part a) Write an equation for the volume of the film canister

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

r is the radius of the circular base

h is the height of the cylinder

we have

$V=32\pi\ cm^3$

$h=8\ cm$

substitute

$32\pi=\pi r^{2}(8)$ ----> equation for the volume of the film canister

Part b) What is the radius of the film canister?

we have

$32\pi=\pi r^{2}(8)$

$32\pi=8\pi r^{2}$

Simplify

Divide by 8π both sides

$4=r^{2}$

square root both sides

$r=2\ cm$

Write an equation in standard form for a line that passes through (4,1) & (5,7)

tatuchka [14]

Y = mx + b

First equation 1 = m(4) + b, bring everything to one side m(4) + b - 1 = 0
Second equation 7 = m(5) + b, bring everything to one side m(5) + b - 7 = 0

Set them equal to each other,

m(4) + b - 1 = m(5) + b - 7

If you bring the b over to the left hand side it becomes

m(4) + b - b - 1 = m(5) - 7

m(4) - 1 = m(5) - 7

Solve for m

6 = m

Plug m = 6 into either equation from the beginning,

m(4) + b - 1 = 0

6(4) + b - 1 = 0

24 + b - 1 = 0

b = -23

Knowing m and b we can now make an equation

y = mx + b

y = 6x -23 Final answer

Rian spends £950 on a plane ticket and $150 on airport tax. Using £1 = $1.35, what percentage of the total cost does Rian spend

WITCHER [35]

Answer:

$150/$1.35 = £111.1 => £950 + £111.1= £1061.1

The total cost does Rian spend on airport tax : (111.1/1061.1) x 100 = 10.47%
