Answer 2

The value of the expression after subtraction will be;

⇒ - 23

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

⇒ (t - 8) - (t + 15)

Now,

Subtract the expression as;

⇒ (t - 8) - (t + 15)

⇒ t - 8 - t - 15

⇒ t - t - 8 - 15

⇒ - 23

Thus, The value of the expression after subtraction will be;

⇒ - 23

whats the answer to 6/7 times 21

Answers

Answer:

slove 6/7 then times it by 21

Step-by-step explanation:

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

Troy is considering two lawn care services. Premier Landscaping charges $15 for travel to Troy's house and $55 per hour for maintaining his lawn. Ace Landscaping does not have a travel fee, but charges $65 per hour for lawn maintenance. Part A Write a system of equations that represent the lawn care services.

Answers

Answer:

Cost for Premier Landscaping = [tex]55h+15[/tex]

Cost for Ace Landscaping = [tex]65h[/tex]

Where [tex]h[/tex] is the number of hours spent on lawn care.

Step-by-step explanation:

Given that:

Charges as per Premier Landscaping:

Fixed charges for travel to the house = $15

Per hour charges = $55

Let [tex]h[/tex] be the number of hours for which lawn care is done.

So, Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$55[tex]h[/tex]

Therefore, total cost = [tex]55h+15[/tex]

Charges as per Ace Landscaping:

Per hour charges = $65

Let [tex]h[/tex] be the number of hours for which lawn care is done.

Then Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$65[tex]h[/tex]

Therefore, system of equations that represent the lawn care services:

Cost for Premier Landscaping = [tex]55h+15[/tex]

Cost for Ace Landscaping = [tex]65h[/tex]

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

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:
