Fine the area of the trapezoid
Answer: The area of the trapezoid can be found using the formula:
Area = (a + b)h/2
where a and b are the lengths of the parallel sides and h is the height (perpendicular distance between the parallel sides).
In this case, the parallel sides are 13ft and 15ft, and the height is 5ft.
Therefore, the area of the trapezoid is:
(13 + 15) * 5 / 2 = (28) * 5 / 2 = 140 / 2 = 70 ft^2
Step-by-step explanation: The area of the trapezoid is calculated by taking the sum of the parallel sides, multiplying by the height and then dividing by 2. The parallel sides are given as 13ft and 15ft, and the height is given as 5ft.
By substituting the given values in the formula we get (13+15)5/2 = 285/2 = 140/2 = 70 ft^2.
So, the area of the trapezoid is 70 ft^2.
joe schmo buys a house for 800,000 dollars. if homes appreciate 7 percent per year, how much will it be in 8 years
The final value would be 1,534,947.20
Joe Schmo:
Joe Shmoe (also spelled Joe Schmoe and Joe Schmo), meaning "Joe Anybody", or no one in particular, is a commonly used fictional name in American English. Adding an "Shm" to the beginning of a word is meant to diminish, negate, or dismiss an argument (for instance, "Rain, shmain, we've got a game to play"). It can also indicate that the speaker is being ironic or sarcastic. This process was adapted in English from the use of the "schm" prefix in Yiddish to dismiss something; as in, "Fancy, schmancy" (thus denying the claim that something is fancy). While "schmo" ("schmoo", "schmoe") is thought by some linguists to be a clipping of Yiddish.
If the home appreciates 7% per year, it will be worth approximately 1,534,947 dollars in 8 years. This can be calculated by multiplying the initial value of the home (800,000) by (1 + 0.07)^8.
You can also use the following formula:

Find the equation of the line passing through the given point and parallel to the given line.
Answer in standard form: 2x+y = 3
Answer in slope intercept form: y = -2x+3
Both equations describe the same line. Select one of those formats to write to your teacher.
=======================================================
Reason:
The equation 2x+y = 9 solves to y = -2x+9; it is of the form y = mx+b
m = -2 = slopeb = 9 = y interceptThe parallel line will also have a slope of -2. Parallel lines have equal slopes, but different y intercepts.
The slope-intercept answer is of the form y = -2x+b
Plug in (x,y) = (-1,5) and solve for b.
y = -2x+b
5 = -2*(-1)+b
5 = 2+b
3 = b
b = 3
We go from y = -2x+b to y = -2x+3 which is in slope intercept form.
Adding 2x to both sides gets us 2x+y = 3 which is in standard form.

A math club ha 30 member. The number of girl i 2 le than 3 time the number of boy. How many member are boy? How many member are girl?
The total number of boys is 8 and that of girls is 22.
Let x be the number of boy members in the math club. According to the problem, the number of girl members is 2 less than 3 times the number of boy members, so we can write the equation:
G = 3*B - 2
We also know that the total number of club members is 30, so we can write the equation:
B + G = 30
We can substitute the first equation into the second equation to eliminate "G":
B + (3*B - 2) = 30
Combining like terms:
4*B - 2 = 30
⇒ 4*B = 30 + 2
⇒ 4B = 32
Dividing by 4:
∴ B = 34/4
⇒ B = 8
So there are 8 boy members in the math club. To find the number of girl members, we can substitute this value back into the first equation:
G = 3*8 - 2 = 22
So there are 22 girl members in the math club.
Therefore,
The number of boys = B = 8
The number of girls = G = 22

Step-by-step explanation:
Solve the following system of Linear Equations:
Answer:
1.) x=1; y=1
2.) x=1; y=5
3.) No solution
Step-by-step explanation:
1.) To start off with number one, we see that in both equations the x and y are positive, and the sums aren't equal to each other, this means we have to do something to make them equivalent. For example, we can multiply the top equation by 8 and the bottom equation by 7, so we get the equations 32x + 24y = 56 and the bottom equation to be 21x+35y=56. From here we can just make the equations equal each other to get 32x+ 24y = 21x +35y. From here we can just get a certain amount of x to equal certain amount of y by taking away the smaller amount of each and bringing it to the other side by subtracting. From that we get 11x = 11y. We can simplify this to be x=y. Now we can substitute either x or y in either equation to get 4x + 3(x) = 7. Then you solve algebraically and you get x=1. Now since we established that x was already equal to y, both x AND y are equal to 1.
2.) For this problem, we have an x that is negative in one equation and positive in the other. This means we can use the method of multiplying the bottom equation by 3 to get 3x +3y = 18. Now we are able to add both equations to each other crossing out the x's because they cancel out. From this we get 4y=20, Which means y=5. We can now plug this back into the equation to get x+(5) = 6. Which means y=5 and x=1.
3.) For this problem, we have both equations equal to y. However the x's are also equal to each other. Meaning if we were to solve them like in problem one, we would get the issue of cancelling the x's out and just getting 13/2=9/2 which is a problem because they do not equal each other. But, we can notice that both of the given systems are linear lines, meaning we could plot them off a graph. But to save time, we can notice that both equations have the exact same slope but different starting positions. Meaning that both lines would be parallel to each other. Since both lines are parallel to each other, There will never be an intersection, or answer between them. Making x and y null (no answer)

What does the number 1,000 represent?Amount of trash originally in the landfillAmount of trash added to the landfill everyday Rate at which the total trash increases everydayRate at which the new trash increases everyday
1000 is the amount of garbage that was initially dumped in the landfill before any additional garbage was added. i.e: It is the quantity of garbage on Day 0.
The initial function given in the problem is n = 2000x + 1000.
The definition of a function's initial value is its starting value, which is unaffected by any variables used in the function.
The given function is:
n = 2000x + 1000
where the amount of trash is n, and the number of days is x. We'll set the variable (x) equal to zero to obtain the starting value.
Therefore, initially:
n = 2000(0) + 1000 = 1000
This indicates that the trash had a value of 1000 at day zero.
Therefore 1000 represents the amount of trash that was originally present in the landfill before dumping any extra trash.

The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.
If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional. If equivalent elements in two sequences have a constant product, also known as the coefficient of proportionality, then the two sequences are inversely proportional.

why is randomization important in an experimental design
Randomization is a crucial step in experimental design that helps to increase the validity and generalizability of the results, by controlling the extraneous variables that might influence the outcome.
Randomization is important in an experimental design because it helps to reduce the effects of confounding variables. Confounding variables are factors that can affect the outcome of an experiment but are not part of the experimental manipulation. By randomly assigning subjects to different groups, the effects of confounding variables will be distributed equally among the groups, making it more likely that any differences observed between the groups are due to the experimental manipulation and not to the confounding variables.
Randomization also helps to ensure that the groups being compared are representative of the population being studied. This is important because if the groups are not representative, the results of the experiment may not be generalizable to the population as a whole.
Additionally, randomization helps to ensure that the groups being compared are not systematically different in ways that could affect the outcome of the experiment. This is important because if the groups are systematically different, it could be difficult to determine whether any differences observed between the groups are due to experimental manipulation or systematic differences.
Therefore, Overall, randomization is a crucial step in experimental design that helps to increase the validity and generalizability of the results, by controlling the extraneous variables that might influence the outcome.

What is a 1 to 1 function graph?
A one-to-one function is a function that assigns a unique output for each input in its domain, and the graph of a one-to-one function will have no vertical asymptotes, cusps, or self-intersections, and will pass the horizontal line test.
A function is said to be one-to-one (or injective) if no two distinct inputs in the domain of the function produce the same output. In other words, a function is one-to-one if it assigns a unique output to each input in its domain.
A graph of a one-to-one function will have the following properties:
The graph will pass the horizontal line test; no horizontal line will intersect the graph more than once.
The graph will have no vertical asymptotes, which would indicate that the function is not defined for certain inputs.
The graph will have no cusps or self-intersections, which would indicate that the function assigns multiple outputs to the same input.
A one-to-one function has a inverse function, which is also a function and satisfies the same properties as the original function.
