Judi Imhoff's previous balance was $717.52. She received $4.36 in interest and had $125.00 and $276.95 in deposits and $90.00 in withdrawals. What is her new balance?
After checking Judi Imhoff's account statement her new balance is $1003.83
What is an account statement?
A statement of accounts is a document that lists all the transactions you have with a certain client during a specific time period. In order to inform their clients of the amount they owe for purchases made during that time period on credit, company owners typically issue statements of accounts to their clients. The manual explains the statement of accounts' contents and demonstrates how to file it for clients.
Your bank may send you a monthly or annual statement if you have a savings account.
account statement for the quarter. All deposits are reflected on the account statement,
withdrawals, as well as interest that is added to your account.
The new balance = Previous Balance + Interest + Deposits - Withdrawals
The new balance = $717.52 + $4.36 + ($125.00 + $276.95) - $90.00
So, the new balance of Judi Imhoff is $1003.83

our school's girls volleyball team has $14$ players, including a set of $3$ triplets: alicia, amanda, and anna. in how many ways can we choose $6$ starters with no restrictions? (the triplets are treated as distinguishable.)
There are 990 ways to select 6 starters from a possible 14 using precisely two of the three triplets.
= C(3,2) = 3! / ( 2! x 1! ) = 3
To select the final 4 starters out of the 11 players ,
= C(11,4) = 11! / (4!7!)
= 330
There are a total of 6 ways to select starters.
= 3*330 = 990
Contrary to permutations, the order of selection is irrelevant when choosing elements from a collection using the combination method.
The number of combinations can be counted in simpler situations. Combination is the taking together of n items, k at a time, without repetition.
The terms k-selection or k-combination with repetition are frequently used to describe combinations where repetition is permitted.

im not sure I'm very very bad at math
Answer:
Step-by-step explanation:
for the first car 374/17 = 22 m per second
for bus 414/23 = 18 m per second
so the car is moving faster
car is moving faster than (22-18)=4 m per second from the bus
Answer: Car: 22 meters per second, Bus: 18 meters per second. The bus travels faster at 4 meters per second.
Step-by-step explanation: First, you should write a proportional relationship for meters per second so the car would be 374/17 and the bus would be written as 414/23. This is so you can know that you divide 374 by 17 to get 18, and 374 by 17 to get 22. So, you had it backward, the bus is faster by 4 meters per second, I hope this helped, for me (a 7th grader) this was review math, so I hoped this helped you.
Consider the line y = 9x - 3.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Zero is the slope of a line parallel to this line.
-1/9 is the slope of a line perpendicular to this line.
What is slope?According to linguists, the Middle English adverb aslope, which meaning "at an angle," is where the term slope is said to have originated. A steep hill or the ramp in a parking garage are examples of things that are at an angle or on a slope and may be described using the word's noun form.
The ratio of the vertical change between two places is referred to as the slope. A line's slope is another indicator of how steep it is. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).
The line becomes: y = 9x - 3
line is in the Slope-Intercept form : y = mx + c
Now comparing this two and we get slope, (m) = 9
So, The line perpendicular will have slope (m') = -1/m
or, m' = -1/9
The line parallel to this line will have slope (m'') = 0
because here the two lines are parallel, so they have no slope.

You are considering taking some courses at your local community college on a part-time basis for the upcoming school year. For a student who carries fewer than twelve credits (the full-time minimum), the tuition is $155 for each credit hour taken. All students, part-time or full-time, must pay a $20 parking fee for the semester. This fixed fee is added directly to your tuition and is included in your total bill. Write an equation to determine the total bill , t, for a student carrying fewer than twelve credit hours. Use n to represent the number of hours taken for the semester. Then, determine the total bill if you take nine credit hours. A. T + 20 = 155 n; $1395 b. T = 155 n + 20; $1395 c. T = 155 n + 20; $1415 d. T + 20 = 155 n; $1415.
The total bill if the student takes nine credit hours at the community college is T = $1415.
What are linear equations?One or more variables can be present in a linear equation, but their maximal possible power is only one. The graph of a linear equation will thus always be a straight line. Y = mx + b, where m denotes the line's slope and b its y-intercept, or point of intersection with the y-axis, is how linear equations are expressed. Many real-world situations, such as the connection between two variables or the distance travelled at a constant pace, may be modelled using linear equations. In order to obtain the value of the variable(s) necessary to make the equation true, one must use algebraic methods.
How to solve?
The total bill, t, for a student carrying fewer than twelve credit hours is given by,
T = 155 n + 20, where n represents the hours taken for semester.
The total bill if the student takes nine credit hours is T = 155(9) + 20 = $1415.

What are ratio and proportion?
An equation known as proportion shows that the two ratios presented are equal to one another. A ratio is the comparative or condensed form of two quantities of the same type. The majority of the explanations for ratios and proportions use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers.
Given, the teacher-to-student ratio is equivalent for all schools.
For school A, ratio of teacher-to-student = 15/330 = 1:22
Then, for school B, the number of students = 23*22 = 506
For school C, the number of teachers = 550/22 = 25
For school D, the number of students = 36*22 = 792

Since this is a right triangle we can use the Pythagorean theorem to solve for side b.
Pythagorean theorem: a²+b²=c²
Since the side length opposite the right angle is the hypotenuse we plug 11.2 in for C

The linear model representing the information is y = 600x + 1500.
To produce 12 solar heaters it cost $8,700.
The domain of the linear model is [1, 80].
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
10 solar heaters = $7500
20 solar heaters = $13,500
The linear model can be in the form of y = mx + c
m = (13,500 - 7500)/(20 - 10)
m = 6000/10
m = 600
Now,
(10, 7500) = (x, y)
7500 = 600 x 10 + c
c = 7500 - 6000
c = 1500
Now,
The linear model is y = 600x + 1500.
Where y is the cost of x solar heaters.
Now,
x = 12,
y = 600 x 12 + 1500
y = 7200 + 1500
y = 8700
Now,
y ≤ 50,000
We see that,
x = 81
y = 600 x 81 + 1500 = 48600 + 1500 = 50,100
x = 80
y = 600 x 80 + 1500 = 48000 + 1500 = 49,500
The domain is from x = 1 to x = 80.
Thus,
The linear model is y = 600x + 1500.
$8,700 is the cost to produce 12 solar heaters.
The domain is [1, 80].
