Eliza Savage received a statement from her bank showing a checking account balance of $324.18 as of January 18. Her own checkbook shows a balance of $487.38 as of January 29. The bank returned all of the cancelled checks but three. The amounts of these three checks are $15.00, $77.49, and $124.28. How much did Eliza deposit in her account between January 18 and January 29?
Answers
3 checks total : 15.00 + 77.49 + 124.28 = 216.77
that amount will still need to be deducted from the bank
so 324.18- 216.77=107.41
her checkbook has a total of 487.38
487.38-107.41 = 379.97 is the amount she deposited into her account
Answer:
The amount she deposited in her account between January 18 and January 29 is $379.97
Step-by-step explanation:
Given :
Eliza showing a checking account balance of $324.18 as of January 18.
Her own checkbook shows a balance of $487.38 as of January 29.
The bank returned all of the cancelled checks but three. The amounts of these three checks are $15.00, $77.49, and $124.28.
To Find : Eliza deposit in her account between January 18 and January 29.
Solution :
Eliza showing a checking account balance of $324.18 as of January 18.
Total amount of three checks = $15.00 + $77.49+ $124.28 =$216.77
The account balance after the deduction of three checks amount
= $324.18 -$216.77 = $107.41
So, the new balance is $107.41.
Her own checkbook shows a balance of $487.38 as of January 29.
So, the amount she deposited between January 18 and January 29
= $487.38-$107.41 = $379.97
Hence , The amount she deposited in her account between January 18 and January 29 is $379.97
Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
Answers
Final answer:
The circumference of a circle with a given area is 75.40 meters
Explanation:
To find the circumference of a circle, we can use the formula C = 2πr, where C is the circumference and r is the radius. First, we need to find the radius from the given area.
The formula for the area of a circle is [tex]A = \pi r^2[/tex]
Rearranging the formula, we get [tex]r = \sqrt{(A/\pi \p).[/tex]
Now, substitute the given area (452.16 square meters) into the formula and solve for r:
[tex]r = \sqrt{(452.16/3.1416)[/tex]
= 12.00 meters
Finally, plug the value of r into the circumference formula:
[tex]C = 2\pi (12.00)[/tex]
= 75.40 meters

Step-by-step explanation:
We are given a graph and to find the equation of graph.
It is a graph of greatest integer function or floor function.
Parent function of greatest integer function:
[tex]f(x)=[x][/tex]
For x = 0 to x= 1 , f(x)=0
For x =1 to x=2 , f(x)=1
We are given a function,
For x = 0 to x= 1 , f(x)=-6
For x = 1 to x= 2, f(x) = -5
If we shift 6 unit down the parent function. We will get original function.

What is the rate of change between the interval x = π and x = three pi over two?
Answers
The rate of change between x = π and x = three pi over two is 6/π.
Explanation:The rate of change between the interval x = π and x = three pi over two can be found by calculating the slope of the line connecting these two points on the graph. In this case, we can calculate the slope by finding the difference in y-values and dividing it by the difference in x-values:
Slope = (y₂ - y₁) / (x₂ - x₁) = (2 - (-1)) / (π - 3π/2) = (2 + 1) / (3π/2 - π) = 3 / (π/2) = 6 / π
Therefore, the rate of change between the interval x = π and x = three pi over two is 6/π.
The rate of change between x = π and x = three pi over two is 6/pi.
Explanation:The rate of change between the interval x = π and x = three pi over two can be found by determining the slope of the line connecting the two points on the graph corresponding to these x-values.
Using the coordinates (pi, -1) and (3 pi over 2, 2), we can calculate the slope as follows:
Slope = (change in y)/(change in x) = (2 - (-1))/(3 pi over 2 - pi) = 3/(pi/2) = 6/pi
So, the rate of change between x = π and x = three pi over two is 6/pi.

The Cool Company determines that the supply function for its basic air conditioning unit is S(p) = 40 + 0.008p^3 and that its demand function is D(p) = 200 - 0.16p^2, where p is the price. Determine the price for which the supply equals the demand.
Answers
S(p) = D(p)
40 + 0.008p³ = 200 - 0.16p²
We transpose all the terms to left side of the equation.
0.008p³ + 0.16p² - 160 = 0
Then, we factor out the given function. This can either be done through long division or synthetic division. Divide the equation by 0.008.
p³ + 20p² - 20000 = 0
One of the roots of the equation is 21.86. This is the only real root of the equation and the rest are imaginary.
Hence, the price should be approximately $21.86 before the demand and supply is breakeven.

72 80 83 85 88 90 91 92 93 94
From the arrangement, we can see that the minimum is 72 and the maximum is 94. Next, the median is the middle number of the data. Since there are 10 data points, we take the average of the middle 2 numbers. The median is (88+90)/2 = 89.
When you talk about the quartiles, you draw divisions in your set. Q₁ is the middle data between the smallest and the median; Q₂ is the median; and Q₃ is the middle data between the largest and the median.
72 80 83 85 88 | 89 | 90 91 92 93 94
Q₁ is 83
Q₂ is 89
Q₃ is 92
Therefore, in summary, the answer is: Minimum = 72, Q1 = 83, median = 89, Q3 = 92, maximum = 94

Three painters can paint three walls in three minutes. how many painters are needed to paint 27 walls in nine minutes?
Answers
To paint 27 walls in 9 minutes, you would need 9 painters working at the same speed. This is based on the proportional relationship that each painter can paint 1 wall in 3 minutes.
Explanation:This problem can be solved with a clear understanding of proportions. Given that 3 painters can paint 3 walls in 3 minutes, it implies that each painter can paint 1 wall in 3 minutes.
Thus, in 9 minutes, a single painter can paint 3 walls.
Therefore, to paint 27 walls in 9 minutes, we would need 27/3 equals 9 painters.
It is important to note that this implies all painters are working at the same speed. This is a simple and practical example of proportions in mathematics

The points in a coordinate plane are reflected in the y-axis. In general, every point (x, y) is mapped onto what point? (___,___)
Answers
In a Cartesian coordinate system, a point (x, y) reflected over the y-axis is mapped to the point (-x, y), as the x-component changes direction in the reflection while the y-component remains the same.
Explanation:When a point is reflected across the y-axis in a Cartesian xy-coordinate system, which has orthogonal directions defined by the unit vectors i and j for the x and y axis respectively, the coordinates of the point change in a specific way. For every point whose coordinates are initially (x, y), after being reflected over the y-axis, the resultant point will have coordinates (-x, y).
This happens because the reflection over the y-axis effectively reverses the direction of the x-component of the point's position vector, changing its sign from positive to negative or vice-versa, while leaving the y-component unaffected. Therefore, after reflection, a point (x, y) is mapped onto the point (-x, y).
