The students in the music club sold tickets to their spring concert. The table shows the
amount of money raised and the number of tickets sold by each of four students.
What is the constant of proportionality for the sales?

Answer:

x= -5

Step-by-step explanation:

if youre looking for the x this is the answer.

Answer:

A-J=4

B-G=50

C-F=2

D-I=32

E-H=8

Answer:

y = 2[tex]\sqrt{5}[/tex], if you plug into expressions for angles K and J they equal 80°

Step-by-step explanation:

from notations given it appears that ΔFKH is similar to ΔIJG, which means their angles are congruent

therefore, we can say that 4y² = 6y² - 40

-2y² = -40

y² = 20

y = √20 or 2√5

to find the measure in degrees, plug 2√5 into each expression:

4 · (2√5)² = 4 · 4 ·5 = 80°

6 · (2√5)² = (6 · 4 ·5) - 40 = 80°

Answer:

B = -3

Answer:

15m−2

Step-by-step explanation:

Distribute the Negative Sign:

=18m + −1(2 + 3m)

=18m + (−1)(2) + −1(3m)

=18m + −2 + −3m

Combine Like Terms:

=18m + −2 + −3m

=(18m + −3m) + (−2)

=15m + −2

Answer:

a. 76 b. 190

Step-by-step explanation:

a. Number of white lights

Since the ratio of blue lights to white lights is 3 to 2 and the number of blue lights is 114, it follows that 3 : 2 = 114 : x where x is the number of white lights.

So, 3/2 = 114/x

cross-multiplying,

3x = 114 × 2

3x = 228

x = 228/3

x = 76

b. Total number of lights

So, the total number of lights is thus number of blue lights + number of white lights = 114 + 76 = 190

Answer:

141.37 ft³ (rounded)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Some of the expressions that can be derived that have the values of 12 are:

i. 2a = 2 x 6

      = 12

ii. 3b = 3 x 4

        = 12

iii. (b  + c) x a = (4 - 2) x 6

                = 2 x 6

                = 12

iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)

                = 8 + 4

                = 12

v. [tex]b^{2}[/tex] -  [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)

             = 16 - 4

             = 12

vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4

             = 16 - 4

             = 12

Answer:

c + d = 400

0.2c + 0.5d = 156

Step-by-step explanation:

Let

c = number of liters of 20% acid solution

d = number of liters of 50% acid solution.

c + d = 400 (1)

0.2c + 0.5d = 400(0.39)

0.2c + 0.5d = 156 (2)

From (1)

c = 400 - d

Substitute c = 400 - d into (2)

0.2c + 0.5d = 156 (2)

0.2(400 - d) + 0.5d = 156

80 - 0.2d + 0.5d = 156

- 0.2d + 0.5d = 156 - 80

0.3d = 76

d = 76/0.3

d = 253.33 liters

Substitute d = 253.33 into (1)

c + d = 400

c + 253.33 = 400

c = 400 - 253.33

c = 146.67 liters

Answer:

x=17

Step-by-step explanation:

So first we know that vertical angles are equal

And for the first part we have a 73 and x

So 73+x=90 Becuase in this situation if you add them up its gonna give you a right angle

you’ll get 17

SO 17 is X

Answer: 73%

Step-by-step explanation:

The plant is capable of producing 10 tons of product in one day.

Currently however, it is only able to produce 7.3 tons per day.

Utilization is therefore:

= Actual production/ Potential production * 100

= 7.3/10 * 100

= 73%

Answer:

21.25

Step-by-step explanation:

The sum of all angles in a triangle equals 180°

Since it's an isosceles triangle, the base angles are congruent.

180 = 75 + (2x + 10) + (2x + 10)

180 = 95 + 4x

-95    -95

85 = 4x

x = 21.25

Step-by-step explanation:

y=3x-5

6x+3y=15

6x+3(3x-5)=15

6x+9x-15=15

15x-15=15

+15 +15

15x=30

/15. /15

x=2

6(2)+3y=15

12+3y=15

-12. -12

3y=3

/3 /3

y=1

(2,1)

The answer is (2,1)

Step-by-step explanation:

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x - 15 = 15

+15 +15

15x = 30

/15 /15

x = 2

6(2) + 3y = 15

Answer:

The length of one of the spoke is 7 m

Option C is correct answer.

Step-by-step explanation:

Area of Ferris Wheel = 154 square meters.

We need to find  the length of one of the spokes.

We are given: Assume  the spokes go from the centre to the edge of the Ferris wheel.

So, We are given area of circle and we need to find radius of circle.

The formula used is: [tex]Area\:of\:circle=\pi \:r^2[/tex]

Putting values and finding radius

[tex]Area\:of\:circle=\pi \:r^2\\154=3.14\:r^2\\r^2=\frac{154}{3.14}\\r^2=49\\Taking\:square\;root\\\sqrt{r^2}=\sqrt{49}\\r=7\:m[/tex]

So, Radius of circle = 7 m

The length of one of the spoke is 7 m

Option C is correct answer.

Answer:

The interest is: $2550.00

Step-by-step explanation:

I = P x r x t

    P is the principal amount, $12000.00.

   r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.

   t is the time involved, 5....year(s) time periods.

   So, t is 5....year time periods.

To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:

The interest is: $2550.00
