Answer:34 play sports; 46 don't play sports

Step-by-step explanation:

80 total students

48 in band

24 band and sport

24 band only

22 neither

10 sports only

80-22 = 58 participants

58-48 = 10

24 both + 10 sports only = play 34 sports

80-34 = 46 don't play sports

Answer:

2x-3

Step-by-step explanation:

f(x) = 3x-1

g(x) = x+2

Find (f-g)(x), this means we need to subtract g from x.

(3x-1) - (x+2)

Subtract the like terms:

3x -x = 2x

-1 -2 = -3

Combine them to get 2x-3

Answer:

6x = 360-138

x= 222/6

x= 37°

Answer:

x = 42˚

Step-by-step explanation:

1) Find the angle shared by 138˚. 180-138 = 42˚.

2) Now we know that one of the angles in the pentagon is 42˚.

3) the other opposite angle is 138˚ as well.

Hopefully this makes sense! I attached a picture below.

Step-by-step explanation:

x = 90 - 54 = 36

Answer:

x = 36

Step-by-step explanation:

The sum of all the angles in a triangle is 180

Add the known angles together

54 + 90 = 144

then subtract 180 and 144 to find x

180 - 144 =36

Answer:

If one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

Step-by-step explanation:

Given that:

The absolute value function:

[tex]d(h) = \dfrac{1}{6}|h - 300| - 50[/tex]

To calculate the position of the buoy where the river bottom is 20 feet below the surface, we equate the absolute value function to the negative value of 20 feet and then solve it for h.

d(h) = -20

[tex]d(h) = \dfrac{1}{6}|h - 300| - 50 = -20[/tex]

Let us add the sum of 50 on both sides, then:

[tex]= \dfrac{1}{6}|h - 300| - 50+50 = -20+50[/tex]

[tex]= \dfrac{1}{6}|h - 300| = 30[/tex]

By multiplying 6 on both sides, we have:

|h - 300| = 30 (6)

|h - 300| = 180

We can attempt the above expression by rewriting it as two equations:

h - 300 = 180   or     h  - 300  = - 180

Let us add 300 to both sides from the two expressions above:

h - 300 + 300 = 180 + 300     or   h - 300 + 300   = -180  + 300

h = 480     or  h = 120

Thus, if one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

[tex]\mathbf{d(h) = \frac 16|h - 300| - 50}[/tex] is an illustration of an absolute function.

The buoy should be placed at 480 feet from the left shore

The function is given as:

[tex]\mathbf{d(h) = \frac 16|h - 300| - 50}[/tex]

To place a buoy at 20 feet below, means d(h) = -20

So, we have:

[tex]\mathbf{-20 = \frac 16|h - 300| - 50}[/tex]

Add 50 to both sides

[tex]\mathbf{30 = \frac 16|h - 300|}[/tex]

Multiply both sides by 6

[tex]\mathbf{180 = |h - 300|}[/tex]

Remove absolute bracket

[tex]\mathbf{h - 300 = -180}\ or\ \mathbf{h - 300 = 180}[/tex]

Make h the subject

[tex]\mathbf{h = 300-180}\ or\ \mathbf{h = 300+180}[/tex]

[tex]\mathbf{h = 120}\ or\ \mathbf{h = 480}[/tex]

This means that, the buoy should be placed at 480 feet from the left shore

Answer:63 degrees

Answer:

x = 7 ± [tex]\sqrt{15}[/tex]

Step-by-step explanation:

Given

4(x - 7)² - 48 = 12 ( add 48 to both sides )

4(x - 7)² = 60 ( divide both sides by 4 )

(x - 7)² = 15 ( take the square root of both sides )

x - 7 = ± [tex]\sqrt{15}[/tex] ( add 7 to both sides )

x = 7 ± [tex]\sqrt{15}[/tex]

Answer:

what does the dot mean? so far without the .4y I got 9

Step-by-step explanation:

Answer:

y = 3x + 6

Step-by-step explanation:

To make the equation we'll use the form y = mx + b, where m is the slope and b is the y-intercept. When a line is parallel to another, both lines have the same slope, so the slope of the equation will be 3. Now that we know the slope, we can input the point (6, -3) into the equation to solve for the y-intercept:

y = mx + b

y = 3x + b

-3 = 3(-3) + b

-3 = -9 + b

Add 9 to both sides to isolate the b:

-3 + 9 = -9 + 9 + b

6 = b

The y-intercept is 6. Let's put that into our equation:

y = 3x + 6

Now we have our answer :)

Answer:

Step-by-step explanation:

The increase in temperature is the product of the increase per hour and the number of hours: 6x.

The temperature at any time is the sum of the initial temperature (30°) and the increase (6x).
