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

[tex]4( x - 7)^2 - 48 = 12[/tex]
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:
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.

Answer:
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:
y=6x+30
Step-by-step explanation:
y is the total temperature
6x is the increase of temperature by 6° per x hours
30 is the y-intercept, you start with this number
9514 1404 393
Answer:
y = 30 + 6xsee below for a graphStep-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).
y = 30 + 6x . . . . . temperature equation
__
This is graphed as a line with an initial value of 30 and a slope of 6. (Note the attached graph has different grid line spacing vertically than horizontally.)

7. The bottom of a river makes a V-shape that can be modeled with the absolute value function,
d(h) = 1/6 |h – 300| - 50 where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet). A ship risks running aground if the bottom of its keel (its lowest point under the water) reaches down to the river bottom. Suppose you are the harbor master and you want to place buoys where the river bottom is 20 feet below the surface. If one buoy is to be placed 120 feet away from the left shore, how far should the second buoy be placed form the left shore?
(Note: A buoy is an anchored float serving as navigation mark, to show reefs or other hazards to guide ships.)
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

Which equation represents a line that passes through the point (6,-3) and is parallel to the graph y=3x+1
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

justin and his friends dan went to the movies if they each bought popcorn for $4.25 and soda for $2.25 what was their total bill after adding 5% of sales tax
Answer:
Step-by-step explanation:
4.25+2.25=6.50 per person
6.50*2 people= 13.00
13.00*5% tax=0.65 tax
13.00+.65= 13.65
Answer:
Step-by-step explanation:
4.25 x 2 + 2.25 x 2 = 13
Convert 5% into a decimal ( 0.05)
0.05 x 13 = 0.65
0.65 + 13 equals 13.65
