<h3>Solution:</h3>

Radius = Diameter ÷ 2 = 13 ÷ 2 = 6.5 cm

Circumference = 2πr

→ Circumference = 2 × π × 6.5

→ Circumference = 13 π cm

Therefore, circumference of given circle = <u>13 π cm</u>

After heating a fixed volume of gas at 50 psia from 300° R to 600°R, its pressure will be:
Vadim26 [7]

Answer:

100 psia

Step-by-step explanation:

Applying,

Pressure law,

P/T = P'/T'................. Equation 1

Where P = initial pressure, P' = Final pressure, T = initial temperature, P' = Final temperature.

make P' the subject of the equation

P' = PT'/T............ Equation 2

From the question,

Given: P = 50 psia, T = 300°R = (300×5/9)K = 166.66 K, T' = 600°R = (600×5/9)K = 333.33 K

Substitute these values into equation 2

P' = (50×333.33)/166.66

P' ≈ 100 psia

P ≈ 100 psia

If Michael and Imani add 18% tip to the bill what does their lunch cost in total
Musya8 [376]

Answer:

X + (0.18 * X)  

where X is the price of the bill without the tip

Step-by-step explanation:

The first thing you have to do is convert the percentage to a decimal value. For example, if it is 30%, its decimal value is 0.30. As simple as dividing that 300 by 100. Repeat the previous step with all the percentages you have to add.

In this case it is 18% therefore the decimal value will be 0.18. As we do not have the value of the account, we will call this value X .

Therefore the total price of the account, that is, with the addition of the tip is as follows:

X + 18% de X =

X + (0.18 + X)
