Answer:

height = 23 ft , Width=43ft

Step-by-step explanation:

Step one:

Given data

Given data

Diagonal = 66ft

Aspect ratio= 19:10

From the formulas below, we can find the dimensions of the theater screen

height = diagonal / √ (AR²+1)

where AR is the aspect ratio

Step two:

height = 66 / √ ((19/10)² + 1) =

height = 66 / 2.9

height = 23 ft

Step three:

Also,

width = AR * height  

width = (19/10) * 22.75

width =1.9* 22.75

Width=43ft

Write the equation for Chelsea's graph in
xeze [42]

Answer:

y=-4x+16.

Step-by-step explanation:

From the given graph it is clear that the y-intercept is 16.

The line passes through (-2,24) and (2,8). So, slope of line is

Slope=\dfrac{y_2-y_1}{x_2-x_1}

Slope=\dfrac{8-24}{2-(-2)}

Slope=\dfrac{-16}{4}

Slope=-4

Slope intercept form of a line is

y=mx+b

where, m is slope and b is y-intercept.

Substitute m=-4 and b=16 in the above equation.

y=(-4)x+(16)

y=-4x+16

Therefore, the required equation is y=-4x+16.

400.0 ml of a gas are under pressure of 80.0 kpa what would the volume of the gas be at a pressure of 100.0 kpa
Ber [7]

Answer:

The final volume is 320 mL at pressure of 100 kPa.

Step-by-step explanation:

Boyle's law gives the relation between volume and pressure of a gas. It states that at constant temperature, volume is inversely proportional to its pressure such that,

V\propto \dfrac{1}{P}\\\\P_1V_1=P_2V_2

Let

V_1=40\ mL\\\\P_1=80\ kPa\\\\P_2=100\ kPa

We need to find V_2. Using above equation, we get :

V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{400\times 80\times 10^3}{100\times 10^3}\\\\V_2=320\ mL

So, the final volume is 320 mL at pressure of 100 kPa.

Evaluate using sine rule:
\frac{c}{sinC}=\frac{b}{sinB}

c=\frac{bsinC}{sinB}

=\frac{10sin90°}{sin30°}

=20

It is required to find the different ways can a student check off one answer to each question.

<h3>What is probability?</h3>

probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

Given:

If a multiple choice test consists of 5 questions each with 4 possible answers of which only one is correct,

,To find  how many different ways can a student check off one answer to each question we have,

: 4^5 = 2^10

= 1024

Therefore, the different ways can a student check off one answer to each question is 1024.
