exercising 30 minutes before lunch or 30 minutes after lunch will help improve heart health more. They will be split into two groups that do not necessarily need to be the same size. One group will exercise and then eat, and the other group will do the same exercises after eating instead. After a month, each person's heart health improvement will be assessed by the same doctor, and the groups will be compared. The participants' names will be on a numbered list based on the order in which they agreed to join the experiment.

divide each term by -2 and simplify
y=-6+[tex]\frac{3x}{2}[/tex] or y=[tex]\frac{3}{2}[/tex]x-6

Ed wants to build a small 800 square foot cabin on a lot that is 80 feet deep. If the building sideyard setbacks are 20 feet and the cabin is 20 feet wide, what is the square footage of the lot
Answers
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
A circular mirror measures 24 cm in diameter.
The cake is cut in half. Work out the perimeter of half of the mirror.
Answers
Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
The diameter of circular measure = 24 cmWe know that the perimeter of a circular shape is called the 'circumference', with the formula
Circumference of a circle = C = 2πrWhen the mirror is cut into half, the diameter gets half as well.
Thus, the diameter of a half mirror = 24/2 = 12 cmWe 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

Brenda and Melissa each have a band. Brenda's band plays songs in sets of 4 and 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?
Answers
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

Answers
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.

On the first day, 8 adult tickets were sold and 13 student tickets were sold for a total of $75. On day two, 10 adult tickets were sold and 9 student tickets were sold for a total of $72. What is the cost of an adult ticket? What is the cost of a student ticket?
Answers
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]
.

Henry's potato vine is growing like crazy! When he planted it, it was 2 inches long. Two weeks later it was 5 inches long. At 6 weeks, it was 11 inches long.
Answers
Answer:
[tex]y = \frac{3}{2}x +2[/tex]
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]

Answers
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]
