How do I solve for #23​

Mathematics

Answer:

137

43

Step-by-step explanation:

A straight line is another way of saying that the angle making the straight line always has 180 degrees. So the two angles in brown add up to 180 degrees.

6x + 20 + 2x + 4 = 180                Combine like terms on the left.

8x + 24 = 180                               Subtract 24 from both sides.

8x + 24-24 = 180-24

8x = 156                                        Divide both sides by 8

8x/8 = 156/8                                  Do the division

x = 19.5

The two angles are

6x + 20 = 6*19.5 + 20 = 117 + 20 = 137

2x + 4 = 2*19.5 + 4 = 39 + 4 =          43

These do add to 180

Answer:

m<RQS = 43 deg

m<TQS = 137 deg

Step-by-step explanation:

The measure of a straight angle is 180 deg.

The measures of angles RQS and TQS add up to 180 deg.

m<TQS + m<RQS = 180

6x + 20 + 2x + 4 = 180

8x + 24 = 180

8x = 156

x = 19.5

m<RQS = 2x + 4 = 2(19.5) + 4 = 43

m<TQS = 6x + 20 = 6(19.5) = 137

C = k - 273.15 (a) Write two other related equations . (b) If the temperature is 23 in degrees Celsius , what is the temperature
Alona [7]

Answer:

(a) k = C + 273.15, F = 1.8(k - 273.15) + 32

(b) k = 296.15

(c) 25 celcius is greater than 300 kelvis.

Step-by-step explanation:

(a) one equation would be to solve for k instead of c, and another related equation could be from kelvin to Farenheit.

C = k - 273.15

C + 273.15 = k

k = C + 273.15

F = 1.8(k - 273.15) + 32

(b) for this one you have to substitute in the previous equation and solve for k.

23 = k - 273.15

k = 23 + 273.15

k = 296.15

(c) you have to convert either kelvins to celcius or celcius to kelvins.

C = k - 273.15

C = 300 - 273.15

C = 26.85

So 25 celcius is greater than 300 kelvis.

Find the work done by gas?
salantis [7]

The work done by the gas when the gas expands will be 567.65 ft-lb.

<h3>What is the work done for an isothermal process?</h3>

The Pressure is inversely proportional to the volume.

Let the initial pressure and initial volume be P₁ and V₁, and the final volume be V₂.

Then the work done by the gas will be

WD = P₁ V₁ ln (V₂ / V₁)

A quantity of the gas with an initial volume of 2 cubic feet and an initial pressure of 700 pounds per square foot.

The gas expands to a volume of 3 cubic feet.

Then the work done by the gas will be

WD = 700 x 2 x ln (3/2)

WD = 1400 x 0.405

WD = 567.65 ft-lb

The work done by the gas when the gas expands will be 567.65 ft-lb.

More about the work done for isothermal process link is given below.
