A rock show is being televised. The lead singer, who is 75 inches tall, is 15 inches tall on a TV monitor. The image of the bass player is 13 inches tall on the monitor. How tall is the bass player? ​

Answers

Answer:

The bass player is 65 inches tall.

Step-by-step explanation:

15 inches is 20% of 75, so the monitor reduces their height by 20%. 13 is 20% of 65, so the bass player must be 65 inches tall.

If you are 600 m from a batter when you see him hit a ball, how long will you wait to hear the sound of the bat hitting the ball? (at 20ºC)?
Speed of sound at 20ºC =?
time =?

Answers

Answer:

The speed of sound at 20°C is 343.42 m/s.

You have to wait 1.75 seconds to hear the sound of the bat hitting the ball

Step-by-step explanation:

Speed of Sound

The speed of sound is not constant with temperature. Generally speaking, the greater the temperature, the greater the speed of sound.

The approximate speed of sound in dry air at temperatures T near 0°C is calculated from:

[tex]\displaystyle v_{\mathrm {s} }=(331.3+0.606\cdot T )~~~\mathrm {m/s}[/tex]

The air is at T=20°C, thus the speed of sound is:

[tex]\displaystyle v_{\mathrm {s} }=(331.3+0.606\cdot 20 )~~~\mathrm {m/s}[/tex]

[tex]v_{\mathrm {s} }=343.42\ m/s[/tex]

The speed of sound at 20°C is 343.42 m/s.

To calculate the time to hear the sound after the batter hits the ball, we use the formula of constant speed motion:

[tex]\displaystyle v=\frac{d}{t}[/tex]

Where d is the distance and t is the time. Solving for t:

[tex]\displaystyle t=\frac{d}{v}[/tex]

Substituting the values v=343.42 m/s and d=600 m:

[tex]\displaystyle t=\frac{600}{343.42}[/tex]

t = 1.75 s

You have to wait 1.75 seconds to hear the sound of the bat hitting the ball

A sketch artist sells on demand portraits and name doodles at the state fair. The artist has a personal maximum of 40 creations per day. With his current paper supply the artist is equipped to create up to 30 portraits and up to 20 name doodles. If the artists profit is $10 on each portrait and $20 on each name doodle, how many of each item should he aim to sell to maximize his profit?

Answers

Answer:

profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600

Step-by-step explanation:

we have to maximize the following equation:

$10P + $20D

where:

P = number of portraits

D = number of doodles

the constraints are:

P + D ≤ 40

P ≤ 30

D ≤ 20

we do not need to use solver or any other type of linear programming tool to solve this, since profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600

-3mn + 4m - 3

-3(2)(-4) + 4(2) - 3

-6(-4) + 8 - 3

24 + 8 - 3

32 - 3 = 29

Answer:

 [tex]\huge\boxed{29}[/tex]

Solution Steps:

______________________________

1.) Fill in the variables with the information given:[tex]-3(2)(-4)+4(2)-3[/tex]

 - M = 2

 - N = -4

2.) Multiply:[tex]-3[/tex] × [tex]2=-6[/tex][tex]4[/tex] × [tex]2=8[/tex]

 - The reason we multiply first is due to Order of Operations or PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

 - When we see y(x) this just means whatever number or variable is before the parenthesis, you multiply it by that.

Equation at the end of Step 2:

[tex]-6(-4)+8-3[/tex]

3.) Multiply again:[tex]-6[/tex] × [tex]-4=-24[/tex]

 - We do this once more because we had one last parenthesis.

Equation at the end of step 3:

[tex]24+8-3[/tex]

4.) Add:[tex]24+8=32[/tex]

Equation at the end of Step 4:

[tex]32-3[/tex]

5.) Subtract: [tex]32-3=29[/tex]

The position of an open-water swimmer is shown in the graph. The shortest route to the shoreline is one that is perpendicular to the shoreline. Write an
equation that represents this path.

Answers

*attachment contains the omitted graph

Answer:

[tex] y = -\frac{4}{3}x + 9 [/tex]

Step-by-step explanation:

The equation that represents the path of the swimmer to the shoreline can be represented in the slope-intercept form, given as [tex] y = mx + b [/tex].

Where,

Slope (m) = the negative reciprocal of the slope of the shoreline, since it is perpendicular to it = ??

y-intercept (b) = ??

Find the slope of the shoreline using, (0, 1) and (4, 4):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 1}{4 - 0} = \frac{3}{4} [/tex].

Since the slope of the shoreline is ¾. The slope of the path of the swimmer would be the negative reciprocal of ¾.

The negative reciprocal of ¾ = -⁴/3.

The slope of the swimmer's path = -⁴/3.

Using the coordinate of the point of the swimmer (6, 1), and the slope of the path, we can find b, the y-intercept of the path.

Substitute x = 6, y = 1 and m = -⁴/3 into y = mx + b, to find b.

Thus:

1 = (-⁴/3)(6) + b

1 = -8 + b

Add 8 to both sides

1 + 8 = b

9 = b

b = 9

Substitute m = -⁴/3 and b = 9 into y = mx + b.

✅The equation that represents the path would be:

[tex] y = -\frac{4}{3}x + 9 [/tex]

Find the slope of the line between the points (0, -4) and (2, 8).
