Aaron tracks the time it takes him to mow lawns by writing coordinate points relating x, the time in hours it takes to mow a lawn, and y, the area of land mowed in acres. Two of his points are (3, 1.5) and (5, 2.5). Which statement describes the slope of the line through these two points? It takes Aaron about 1 hour to mow 2 acres. Aaron’s rate for mowing lawns is 0.5 acres per hour. The ratio of acres to time is 5 acres to 3 hours. The rate to mow a lawn is 0.6 hours per acre.
Answers
Answer: Aaron’s rate for mowing lawns is 0.5 acres per hour
Step-by-step explanation:
Hope this helps!!
The statement "The rate to mow a lawn is 0.5 acres per hour" correctly describes the slope of the line passing through the given points.
We have,
To determine the slope of the line passing through the points (3, 1.5) and (5, 2.5), we can use the slope formula:
Slope = (change in y) / (change in x)
Given the two points, we can calculate the change in y and the change in x:
Change in y = 2.5 - 1.5 = 1
Change in x = 5 - 3 = 2
Plugging these values into the slope formula:
Slope = 1 / 2 = 0.5
The slope represents the rate of change of the y-coordinate (area) with respect to the x-coordinate (time).
In this case, a slope of 0.5 means that for every hour it takes Aaron to mow a lawn (change in x), the area mowed (change in y) increases by 0.5 acres.
Therefore,
The statement "The rate to mow a lawn is 0.5 acres per hour" correctly describes the slope of the line passing through the given points.

• How many hours each moose spends in the water each day.

The 13 moose are the individuals. There are four categorical variables and one quantitative variable.

Answers
The correct answer is C. The 13 moose are the individuals. There is one categorical variable and four quantitative variables.
Explanation:
In research, the individuals refer to the participants or population that is being analyzed. For example, if the purpose of the research is to know how many hours highschool students sleep, the individuals are high school students. In this context, the individual or population of this study ae the 13 moose.
Moreover, this research focuses on different variables such as gender, height, the number of hours each moose spends in the water, the weigh of the food eaten on average by each moose, and the average weight of food eaten every day. From these variables, the last four variables are quantitative because they can be measured using numbers, for example, the height is measured in inches. On the other hand, the first variable is categorical because each moose can be classified in only two categories: male or female.

the sum of the internal angles of a triangle are equal to 180 degrees.
once i remembered that the problem became a lot easier.
let a, b, and c be the angles of the triangle.
-----
let a = 2*b
-----
let c = a+b-12
-----
the above two statements are given.
since the sum of the internal angles of a triangle are equal to 180, then we have a third equation to work with which is
-----
a + b + c = 180
-----
we now have 3 equations for 3 unknowns and we should be able to solve for each of the unknowns.
-----
it looks like the easiest thing is to solve for b. once we find b, the rest should fall into place very nicely.
-----
since a = 2*b, we can substitute 2*b for a in the equation a + b + c = 180.
that equation then becomes 2*b + b + c = 180 which becomes 3*b + c = 180.
looking at the equation c = a + b - 12, we solve for b as follows:
since we know that a = 2 * b, we can substitute 2*b for a and the equation becomes c = 2*b + b - 12 which becomes c = 3*b - 12.
-----
the equation we are working with is 3*b + c = 180 which originally started as a + b + c = 180.
we can substitute 3*b - 12 for c and the equation becomes
3*b + 3*b - 12 = 180 which becomes 6*b = 192 after adding 12 to both sides and combining like terms.
dividing both sides of the equation by 6 and we get b = 32 degrees.
-----
we have b = 32 degrees.
we have a = 2 * b so a = 64 degrees.
we have c = a + b - 12 which becomes c = 32 + 64 - 12 which becomes c = 96 - 12 which becomes c = 84 degrees.
-----
substituting in the equation a + b + c = 180, we get 32 + 64 + 84 = 180 which becomes 96 + 84 = 180 which becomes 180 = 180.

Answers
Answer:
When we have a function y = f(x)
The set of the possible values of x is called the domain, and the set of the possible values of y is called the range.
In this case, we have:
x = age, and y = price.
x y
< 5 $0
5 - 17 $25
18 - 64 $40
≥ 65 $35
Then the range is the possible age of the customer, and it goes for all the possible ages (as whole numbers)
So the domain will be the set of all the positive integers:
D = {1, 2, 3, 4, 5, ...}
(of course, we can not have an age equal to 1300 or infinity, but we really can not cap the domain)
The range is the possible values of y, in this case is discrete, because we have only 4 possible prices, so the range is:
R = {$0, $25, $40, $35}

Using an exponential equation, it is found that the account will enable the person to purchase the computer after 153 months.
An exponential equation of increase is modeled by:
[tex]A(n) = A(0)(1 + r)^n[/tex]
In which
A(0) is the initial value.r is the rate of increase, as a decimal.In this problem:
$200 put into the account, thus [tex]A(0) = 200[/tex].Increases 0.6% each month, thus [tex]r = 0.006[/tex].Then:
[tex]A(n) = A(0)(1 + r)^n[/tex]
[tex]A(n) = 200(1 + 0.006)^n[/tex]
[tex]A(n) = 200(1.006)^n[/tex]
You need $500 to purchase the computer, then:
[tex]A(n) = 200(1.006)^n[/tex]
[tex]500 = 200(1.006)^n[/tex]
[tex](1.006)^n = \frac{500}{200}[/tex]
[tex](1.006)^n = 2.5[/tex]
[tex]\log{(1.006)^n} = \log{2.5}[/tex]
[tex]n\log{1.006} = \log{2.5}[/tex]
[tex]n = \frac{\log{2.5}}{\log{1.006}}[/tex]
[tex]n = 153[/tex]
The account will enable you to purchase a computer after 153 months.

Answers
Answer:
First problem: 1088 [tex]m^{3}[/tex]
Second problem: 554.3 [tex]m^{3}[/tex]
Step-by-step explanation: Please see the images below!
The volumes of both the pyramids are 1088 m³ and 554.3 in³.
What is volume?The volume of a shape or solid is the space occupied by it, which also includes its height or depth.
a) To find the volume of the pyramid, first calculate the area of the base.
B = lw
Substitute 16 for l and 12 for w.
B = 16 ⋅ 12
Simplify.
B = 192 m²
To find the volume of the pyramid, use the formula for the volume of a pyramid.
V = 1/3 Bh
Substitute 192 for B and 17 for h.
V = 1/3 ⋅ 192 ⋅ 17
Simplify.
V = 1088 m³
Therefore, the volume of the rectangular pyramid is 1088 m³.
b) Similarly for the volume of a regular hexagonal pyramid with base edge length 8 in. and height 10 in.
Base area = 96√3 in²
Volume = 1/3 × 96√3 in² × 10 in
= 554.3 in³
Hence, the volumes of both the pyramids are 1088 m³ and 554.3 in³.
