If Loretta accidentally recorded a deposit of $47.88 as a debit in her register, by how much will her register differ from the bank statement?
If Loretta accidentally recorded a deposit of $47.88 as a debit in her register, her check register will differ from the bank statement by $0.
How is a deposit recorded in the check registered?A deposit amount is debited to the check register as an asset, increasing the amount the account holder has in the bank.
It is the bank's responsibility to credit the deposit since it is a liability to them, not an asset.
Under accounting principles, assets are debited while liabilities are credited. Loretta's debit entry in her register does not constitute an accounting error under the generally-accepted accounting principles.
Thus, Loretta has not committed an accounting error by recording a deposit of $47.88 as a debit in her register, and her register will not differ from the bank statement for this reason.

Sketch a polygon that will map to itself after a rotation of 60°.
A polygon will map to itself after a rotation of a 60° would be a regular hexagon.
What is a polygon?
A polygon is a closed, two-dimensional geometric shape that is defined by a set of straight lines, called its sides, that are connected end-to-end. The number of sides in a polygon is referred to as its "order" or "degree"
A polygon that maps to itself after a rotation of 60 degrees is called a regular hexagon. A regular hexagon is a polygon with six sides of equal length and six angles of equal measure (120 degrees each).
To sketch a regular hexagon, you can start by drawing a dot in the middle of a piece of paper. From there, use a compass or a straightedge to draw a circle around the dot. Then, use the compass to draw six lines from the center of the circle to the edge of the circle, each line being 60 degrees apart from the other. Finally, connect the endpoints of each line to form a six-sided polygon.
Hence, a polygon will map to itself after a rotation of a 60° would be a regular hexagon.

Rewrite the following equation in slope-intercept form
10x - 12y = 1
Answer:
y = 5/6x - 1/12
Step-by-step explanation:
The slope-intercept form is y = mx + b
10x - 12y = 1
We subtracted 10x from both sides
-12y = -10x + 1
Divided by -12 both sides
y = -10/-12x - 1/12
To simplify we can get
y = 5/6x - 1/12

Answer:
[tex]A = 125 \textrm{ yd}^2[/tex]
Step-by-step explanation:
The area of a triangle can be solved for using the formula:
[tex]A_\triangle = \dfrac{1}{2}b h[/tex]
where [tex]b[/tex] is the length of the triangle's base and [tex]h[/tex] is the length of its height (altitude).
Both [tex]b[/tex] and [tex]h[/tex] are given to us for the shown triangle, so all we have to do is plug the given values into the triangle area formula above.
[tex]A = \dfrac{1}{2} \cdot 10 \cdot 25[/tex]
[tex]A = 5 \cdot 25[/tex]
[tex]A = 125 \textrm{ yd}^2[/tex]
Note that the height of the triangle is given on the outline of an auxiliary (dotted) right triangle. This is just to show that the height is in fact an altitude, meaning it is perpendicular to the base, not at the angle of the triangle's other sides.

Find the value of tan T rounded to the nearest hundredth, if...
The measure of the tan of the angle T is 3.4286
How to determine the measure of the tan of the angle TFrom the question, we have the following parameters that can be used in our computation:
Opposite = RS
Hypotenuse = 50
Adjacent = 14
The opposite of the angle T can be calculated as
Hypotenuse² = Opposite² + Adjacent²
Substitute the known values in the above equation, so, we have the following representation
50² = RS² + 14²
Evaluate the like terms
RS² = 2304
Take the square root of both sides
RS² = 48
The measure of the tan of the angle T is then calculated as
tan(T) = RS/Adjacent
Substitute the known values in the above equation, so, we have the following representation
tan(T) = 48/14
Evaluate
tan(T) = 3.4286
Hence, the value is 3.4286

The value of a is 3√3/2 and value of b is 3/2. The solution has obtained using the trigonometry formulas.
What is trigonometry?
The study of the right-angle triangle's sides, angles, and connection is the main focus of the field of mathematics known as "trigonometry." Therefore, it helps to find the unknown or missing angles or sides of a right triangle using the trigonometric formulas, functions, or trigonometric identities. The angles in trigonometry can either be expressed in degrees or radians. The most used trigonometric angles for computations include 0, 30, 45, 60, and 90 degrees.
In the figure, we are given that one angle measures 30° and the other measures 90° and the hypotenuse is 3.
So, using trigonometry, we know that
Cos theta = adjacent side/hypotenuse
And, Cos 30° is √3/2
So,
⇒√3/2 = a/3
⇒a= 3√3/2
Sin theta = opposite side/hypotenuse
And, Sin 30° is 1/2
So,
⇒1/2 = b/3
⇒b= 3/2
Hence, the value of a is 3√3/2 and value of b is 3/2.

Answer: Roger should pick Printer B because it prints 2 more pages per minute.
Step-by-step explanation: We are given that printer A prints 33 pages per minute. We have to figure out how many pages printer B prints in a minute.
As shown in the table, in 2 minutes, printer B prints 70 pages, and in 3 minutes it prints 105 pages. We can create a function to model the rate at which printer A prints pages. This is a linear function since for each increase in x, there is a proportional increase in y. This means that if we were to back one minute the printer would print 35 pages since the common difference per minute is 35 pages. The function would therefore be p=35m where m=minutes and p=pages. This means that printer B produces 2 more pages than printer A per minute since 33+2=35.

find the equation of the lines on the graph
The equation of the line in slope intercept form is y = 1 / 2 x - 3 / 2.
How to find the equation of a line?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptLet's find the slope of the line using the coordinates.
Therefore, using (-1, -2) and (-5, -4)
Hence, the slope of a line is the change in the dependent variable with respect to the change in the independent variable.
Therefore,
m = -4 + 2 / -5 + 1
m = - 2 / -4
m = 1 / 2
Therefore, let's find the y-intercept using (-1, -2)
y = 1 / 2 x + b
-2 = 1 / 2 (-1) + b
-2 + 1 / 2 = b
- 3 / 2 = b
Therefore, the equation of the line is y = 1 / 2 x - 3 / 2.
