Answer:

12 songs

Step-by-step explanation:

Brenda's band plays songs in sets of 4

Melissa's band plays songs in sets of 6.

After performing together, both bands realize that they have played the same number of songs.

What is the smallest number of songs each band could have performed?

The smallest number of songs each band could have performed can be calculated by finding the lowest common multiple of 4 and 6

4 = 8, 12, 16, 20, 24, 28, 32, 36, 40

6 = 12, 18, 24, 30, 36, 42

The lowest common multiple of 4 and 6 is 12

The smallest number of songs each band could have performed is 12 dongs

Answer:

a. k = 24 b. y = [tex]Ae^{4t} + Be^{6t}[/tex]

Step-by-step explanation:

a. Find the value of the constant k

Since  [tex]y = e^{4t}[/tex] is a solution of d²y/dt² -10dy/dt + ky = 0, then  [tex]y = e^{4t}[/tex] must satisfy the equation.

So, d²y/dt² =  [tex]16e^{4t}[/tex] and dy/dt =  [tex]4e^{4t}[/tex]

So, d²y/dt² -10dy/dt + ky = 0

[tex]16e^{4t}[/tex] - 10([tex]4e^{4t}[/tex]) + k([tex]e^{4t}[/tex]) = 0

[tex]16e^{4t}[/tex] - [tex]40e^{4t}[/tex] + [tex]ke^{4t}[/tex] = 0

 - [tex]24e^{4t}[/tex] + [tex]ke^{4t}[/tex] = 0

- [tex]24e^{4t}[/tex] =  -[tex]ke^{4t}[/tex]

So, k = 24

b. Find the general solution to this equation.

Since k = 24, our equation is

d²y/dt² -10dy/dt + 24y = 0

The characteristic equation is thus

m² - 10m + 24 = 0

Factorizing this we have

m² - 6m - 4m + 24 = 0

m(m - 6) - 4(m - 6) = 0

(m - 6)(m - 4) = 0

m - 6 = 0 or m - 4 = 0

m = 6 or m = 4

Since we have real roots for the characteristic equation, then, the general solution is

y = [tex]Ae^{4t} + Be^{6t}[/tex]

Answer:

Perimeter = 6x + 5.

Step-by-step explanation:

The perimeter is the sum of the three sides.

Perimeter = 3x - 2 + (-5x) + 8x + 7

= 3x - 2 - 5x + 8x + 7

= 3x - 5x + 8x - 2 + 7

= 6x + 5.

Step-by-step explanation:

Required:

Write an equation to represent this  situation

Let x represents the number of weeks and y represents the growth.

When he planted it:

[tex](x_1,y_1) = (0,2)[/tex]

Two weeks later:

[tex](x_2,y_2) = (2,5)[/tex]

At 6 weeks:

[tex](x_3,y_3) = (6,11)[/tex]

Start by calculating the slope (m)

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

[tex]m = \frac{5-2}{2-0}[/tex]

[tex]m = \frac{3}{2}[/tex]

Then calculate the equation using:

[tex]y - y_3 = m(x - x_3)[/tex]

[tex]y - 11 = \frac{3}{2}(x - 6)[/tex]

[tex]y - 11 = \frac{3}{2}x - 9[/tex]

Solve for y

[tex]y = \frac{3}{2}x - 9+11[/tex]

[tex]y = \frac{3}{2}x +2[/tex]

Answer:

4800 ft²

Step-by-step explanation:

Given that :

Area of cabin = 800 ft²

Width of cabin = 20 feets

Side yard setback of building = 20 feets

Depth of lot = 80 feets

The cabin is a rectangle :

Area of rectangle = Length * Width

800 = length * 20

Length = 800 / 20 = 40 feets

Hence,

Width of lot = side yard + Width of cabin = (20 + 20) = 40 feets

Length of lot = depth +. Length of cabin = (80 + 40) = 120 feets

Area of lot = Length of lot * width of lot

Area of lot = 120 ft * 40 ft = 4800 ft²

Answer:

Adult ticket = $4,5

Student ticket = $3

.

Step-by-step explanation:

Let say adult ticket is x and student ticket is y. so we get:

→ 8x + 13y = 75 (×5) 40x + 65y = 375

→ 10x + 9y = 72 (×4) 40x + 36y = 288

.

Eliminate both equations

40x + 65y = 375

40x + 36y = 288    

29y = 87

[tex]y = \frac{87}{29}[/tex]

[tex]y = 3[/tex]

.

Substitute the value of y to one of equations

[tex]10x + 9(3) = 72[/tex]

[tex]10x + 27 = 72[/tex]

[tex]10x = 72 - 27[/tex]

[tex]10x = 45[/tex]

[tex]x = \frac{45}{10}[/tex]

[tex]x = 4,5[/tex]

.

Answer:

11/12

Step-by-step explanation:

find the lcm of 12 and 3 which is 12.

find a common factor in 12 and 3 and use those factors to multiply with their numerators.

7 * 1 and 1*4 =11

while the denominator or the lcm is 12

thus 11/12

Answer:

4 different sums

Step-by-step explanation:

There are two ways to form a sum: either by leaving out one coin or by not leaving out any. There are three options if we want to leave out one coin, and obviously only one way to not leave out any, so that gives us our answer of [tex]$3+1=\boxed{4}$[/tex] .

Hope this helped! :)

Answer:

The perimeter or circumference of a half mirror = 37.68 cm

Step-by-step explanation:

We know that the perimeter of a circular shape is called the 'circumference', with the formula

When the mirror is cut into half, the diameter gets half as well.

We know that radius = r = diameter / 2 = 12/2 = 6 cm

Thus, the perimeter of half of the mirror  = C = 2πr

                                                                           = 2(3.14)6

                                                                            = 37.68 cm

Therefore, the perimeter or circumference of a half mirror = 37.68 cm

Answer:

Slope: 3/2

y intercept (0,-6)

Step-by-step explanation:

3x-2y=12

First, solve for y

2y=12-3x

divide each term by -2 and simplify

y=-6+[tex]\frac{3x}{2}[/tex] or y=[tex]\frac{3}{2}[/tex]x-6

Slope intercept form: y=mx+b

therefor m =[tex]\frac{3}{2}[/tex] and y (0,-6)

Answer:

11 dollars

Step-by-step explanation:

82-16=66

You subtract the money she has left over and then divide that number by the amount of books that were bought

66 Divided by 6 = 11

Note: Consider all the numeric values are in the fraction form. Like [tex]14\to \dfrac{1}{4}[/tex], [tex]23\to \dfrac{2}{3}[/tex] etc.

Given:

A recipe calls for [tex]\dfrac{1}{4}[/tex] cup of brown sugar for every [tex]\dfrac{2}{3}[/tex] cup of white sugar.

To find:

The number of cups of brown sugar that are required for every cup of white sugar.

Solution:

We know that,

Required brown sugar for [tex]\dfrac{2}{3}[/tex] cup of white sugar =  [tex]\dfrac{1}{4}[/tex] cup

Using this, we get

Required brown sugar for 1 cup of white sugar =  [tex]\dfrac{\dfrac{1}{4}}{\dfrac{2}{3}}[/tex] cup

                                                                              [tex]=\dfrac{1}{4}\times \dfrac{3}{2}[/tex] cup

                                                                              [tex]=\dfrac{3}{8}[/tex] cup

So, [tex]\dfrac{3}{8}[/tex] cup of brown sugar is required for every cup of white sugar.

Therefore, the correct option is B.

Answer:

  both C and D are correct

Step-by-step explanation:

The diagram shows that x is the total of $40 and 20% of $40.

Description A would be represented by the difference of $40 and 20% of $40, not the sum.

Description B would be represented by 20% of $40, not the sum of that and $40.

Both descriptions C and D are properly represented in the diagram.
