e=15.5m is the equation which represents the relationship between the number of lawns mowed m and his total earnings e.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We have to find the equation represents the relationship between the number of lawns mowed m and his total earnings e.
Winslow earns $15.50 for each lawn that he mows.
e=15.5m is the equation
Now let us find earnings for 0, 1, 2, and 3 lawns mowed.
Plug in 0, 1 , 2 and 3 in m
When m=0 then e=15.5(0)
e=0
When m=1 then e=15.5(1)
e=15.5
When m=2 then e=15.5(2)
e=31
When m=3 then e=15.5(3)
e=46.5
Hence, e=15.5m is the equation which represents the relationship between the number of lawns mowed m and his total earnings e.

-know the number of possible lunch options.
-P of having any meal with NO COOKIE.
(use sample space, tree diagram, and counting principle)
Answers
1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.
How to find the number of possible lunch options.1) Number of possible lunch options:
To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.
- Sandwich: There are 3 options (turkey, roast beef, or bologna).
- Fruit: There are 2 options (orange or apple).
- Dessert: There are 2 options (cookie or muffin).
Using the counting principle, we multiply the number of options for each component together:
Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.
Therefore, there are 12 possible lunch options.
2) Let's examine the favorable outcomes for each component:
- Sandwich: There are still 3 options (turkey, roast beef, or bologna).
- Fruit: There are 2 options (orange or apple).
- Dessert: There is 1 option (muffin, as we want to exclude cookies).
Using the counting principle, we multiply the number of options for each component together:
Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.
The total number of possible outcomes is still 12 (as calculated in the previous step).
Therefore, the probability of having any meal with no cookie is:
P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.
Hence, the probability of having any meal with no cookie is 1/2 or 0.5.

Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

How to calculate the mean of any data set?In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:
Mean, \bar{x} = ∑x/n
Where:
∑x represents the sum of all data values.n represents the total number of data items.Based on the information provided, we have:
Mean of Yard Works = (7+9+7+12+5)/5
Mean of Yard Works = 8.
Mean of Grow Station = (9+11+6+12+7)/5
Mean of Grow Station = 9.
Range is the difference between the maximum and minimum numbers;
Range of Yard Works = 12 - 5
Range of Yard Works = 7.
Range of Grow Station = 12 - 6
Range of Grow Station = 6.
Mean absolute deviation is given by;
MAD = 1/n ∑|x - μ|
Where:
n represents the number of data (observed values)μ represents the mean of the data set.x represents the individual data (values)Mean absolute deviation of Yard Works = 2

There are two glass pyramids at the Louvre Museum in Paris, France. The outdoor pyramid has a square base with side lengths of 35.4 meters and a height of 21.6 meters. The indoor pyramid has a square base with side lengths of 15.5 meters and a height of 7 meters. How many times as great is the volume of the outdoor pyramid than that of the indoor pyramid?
Answers
Volume = (1/3) x base area x height
To find the ratio of the volume of the outdoor pyramid to the indoor pyramid, we need to calculate the volumes of each pyramid and divide the volume of the outdoor pyramid by the volume of the indoor pyramid.
Volume of outdoor pyramid = (1/3) x (35.4 m)^2 x 21.6 m = 22,665.6 cubic meters
Volume of indoor pyramid = (1/3) x (15.5 m)^2 x 7 m = 840.58 cubic meters
Ratio of volume of outdoor pyramid to indoor pyramid = 22,665.6 cubic meters / 840.58 cubic meters
Ratio = 26.97
Therefore, the volume of the outdoor pyramid is approximately 27 times greater than that of the indoor pyramid.

In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.
