Answer: 75%

Step-by-step explanation:

We are told that in a group of 120 band students 30 of them play a woodwind instrument. The number of those that don't play woodwind instrument would be:

= 120 - 30 = 90

The percent of the band students that do not not play a woodwind instrument will be:

= 90/120 × 100

= 3/4 × 100

= 75%

Answer:

The equation for the perpendicular bisector of the line segment will be:

[tex]y=-\frac{7}{2}x-13[/tex]

Step-by-step explanation:

Given the endpoints of the line segments

Determining the slope between (5,-4) and (-9, -8)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(5,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-9,\:-8\right)[/tex]

[tex]m=\frac{-8-\left(-4\right)}{-9-5}[/tex]

[tex]m=\frac{2}{7}[/tex]

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:  

slope = m = 2/7

Thus, the slope of the the new perpendicular line = – 1/m = (-1)/(2/7)= -7/2

Next, determining the mid-point between  (5,-4) and (-9, -8)

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(5,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-9,\:-8\right)[/tex]

[tex]=\left(\frac{-9+5}{2},\:\frac{-8-4}{2}\right)[/tex]

Refine

[tex]=\left(-2,\:-6\right)[/tex]

We know that the point-slope form of equation of line is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

substituting the slope of the perpendicular line -7/2 and the point (-2, -6)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-6\right)=-\frac{7}{2}\left(x-\left(-2\right)\right)[/tex]

[tex]y+6=-\frac{7}{2}\left(x+2\right)[/tex]

Subtract 6 from both sides

[tex]y+6-6=-\frac{7}{2}\left(x+2\right)-6[/tex]

[tex]y=-\frac{7}{2}x-13[/tex]

Therefore, the equation for the perpendicular bisector of the line segment will be:

[tex]y=-\frac{7}{2}x-13[/tex]

Answer:

Since a triangle has 180 interior degrees, and 81+57=138, and 180-138=42, you need to find _*2+18=42. (Hint, you can subtract the 18 from the 42, and find _*2=24).

Answer:

x= 28 and y=21

Step-by-step explanation:

x - y = 7

x + y = 49

add the two equation and the y's will cancel out

2x = 56  divide by 2

x = 28

replace 28 for x in the first equation and solve for y

28 - y = 7

y = 21

Answer:

[tex]-12b + 6c + 18[/tex]

Step-by-step explanation:

The key to answering this question is combining like terms. Add or subtract the terms that have the same variable.

1) Let's start with finding all the terms that have a b and combine them - those terms would be -4b and -8b. Add their coefficients (the numbers in front of the variable).

[tex]-4b + 8c + 12 - 8b - 2c + 6 \\= -12b + 8c + 12 - 2c + 6 \\[/tex]

2) Next, let's do the same with all the terms that have a c. In this case, those terms would be 8c and -2c. So, add their coefficients too:

[tex]-12b + 8c + 12 - 2c + 6 \\\\= -12b + 6c + 12 + 6[/tex]

2) Finally, combine the constants (the terms with no variables). Those numbers would be 12 and 6.

[tex]-12b + 6c + 12 + 6\\= -12b + 6c + 18[/tex]

Thus, the answer is [tex]-12b + 6c + 18[/tex].

Answer:1.24

2.52

3.20

Step-by-step explanation:

Answer:

The number is 31

Step-by-step explanation:

Let the number be x

Subtract 12 from the number = x - 12

Then multiply the difference by -7 = (-7)*(x - 12)

(-7)(x - 12) = -133

-7x - 12*(-7) = -133      

-7x  + 84    = - 133

           -7x = -133 - 84

          -7x  = -217

             x  = -217/-7

            x = 31

Step-by-step explanation:

m3/9=3

We move all terms to the left:

m3/9-(3)=0

We multiply all the terms by the denominator

m3-3*9=0

We add all the numbers together, and all the variables

m^3-27=0

Answer:

1)Is it a 0.7 percent chance that green is not going to choosed

2)25

Step-by-step explanation:

1)Probability of A NOT occuring: P(A') 0.7

Probability of B NOT occuring: P(B') 0.5

Probability of A and B both occuring: P(A∩B) 0.15

Probability that A or B or both occur: P(A∪B) 0.65

Probability that A or B occurs but NOT both: P(AΔB) 0.5

Probability of neither A nor B occuring: P((A∪B)') 0.35

Probability of A occuring but NOT B: 0.15

Probability of B occuring but NOT A: 0.35

Answer:

$142.26 - x ≥ $30

x ≤ $112.26

Step-by-step explanation:

Let the amount you can write on your next check without being charged a fee be x.

Given that you are to have at least $30 in your account or else you are charged a fee then

$142.26 - x ≥ $30

To solve, collect like terms

-x ≥ $30 - $142.26

-x ≥ -$112.26

x ≤ $112.26

Note that on dividing both sides by -1, the sign changes from greater than to less than.

Answer: Final elevation of butterfly = 4m

Final elevation for diver = -11m

Final elevation for whale= 2m

Final elevation for fish = -20m

Step-by-step explanation:

Final elevation= Initial poistion + Change.

A butterfly starts at 20 m and changes -16 m.

Final elevation = 20m +(-16m)

= 20-16 m   [(-)(+)=(-)]

= 4m

A diver starts at 5 m and changes -16 m.

Final elevation = 5m + (-16) m

= 5m- 16 m  [(-)(+)=(-)]

= -11 m

A whale starts at -9 m and changes 11 m.

Final elevation = (-9m)+11m

= 11m- 9m   [-a+b=b-a]

= 2m

A fish starts at -9 meters and changes -11 meters

Final elevation = -9+(-11) m

= (-9-11) m     [(-)(+)=(-)]

=-(9+11)  m   [-a-b=-(a+b)]

=-20m

Hence, Final elevation of butterfly = 4m

Final elevation for diver = -11m

Final elevation for whale= 2m

Final elevation for fish = -20m
