Deborah spends $1821 to buy the computer.
What is the percentage?One of the various ways to express a number, ratio, or fraction is as a percentage. In daily life, it is often used to describe probability, grades, and much more. The symbol used to represent it is %. Assume that 10% corresponds to 0.01, 10%, 10/100, or ten hundredths.
Given that, Deborah gets the 25% off on the computer that she purchased.
the final value of computer =(1- 25%) * 2428
the final value of computer = (3/4) * 2428
the final value of the computer = 1821
Therefore, Deborah total spends 1821$ o the computer after the off.

Answer:
42.5 if rounding 43 for B
Step-by-step explanation:
P is the variable so put 100 under it
Then on the first empty fraction put 17/40
Cross multiply
You will get 40p=17x100
So then you multiply 17 by 100
1700
divided both sides by 40
Get the variable alone
Divide 1700 by 40
get 42.5
If your teacher is as annoying as mine round to 43

Answer:

Step-by-step explanation:
The structure is shaped as a right triangle.
Use the Pythagorean theorem to solve for 'c' or the hypotenuse.
[tex]a^2+b^2=c^2\\\\8^2+15^2=c^2\\\\64+225=c^2\\\\289=c^2\\\\\sqrt{289} =\sqrt{c^2}\\\\17, -17 = c\\\\\text{Disregard negative value.}\\\\\boxed{17=c}[/tex]
The hypotenuse should be 17 feet.
Hope this helps!
Answer: 17 ft.
Step-by-step explanation: By using the pythagorean theorem (a^2 + b^2 = c^2) for right triangles, you should be left with the given equation after plugging in the values of the legs:
8^2 + 15^2 = c^2
Now simplify the squares
64 + 225 = 289 (c^2)
Now to find the exact value of the hypotenuse (c), square root the value of c^2.
√289 = 17
The hypotenuse of the triangles is 17 ft.

The perimeter of a square is represented by the expression (32x – 12) feet.
Find the perimeter of the square if x = 2.
Answer:
52
Step-by-step explanation:
I think it would probably just be 52 because if you replace (x) with (2) and simplify the equation, you get 52.
32x-12
*replace x with 2*
32(2)-12
*multiply 32 by 2*
64-12
*solve 64-12*

how many angles must be supplementary with angle 14? 4 lines intersect to form 16 angles. The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16; 9, 10, 11, 12.

There are two angles m∠14 and m∠13 which are supplementary to angle 14.
AngleAngle is formed by the intersection of two lines. Two angles are said to be supplementary if both of the angles add up to 180 degrees.
From the diagram:
m∠13 + m∠14 = 180° (sum of angles in a straight line )
Also:
m∠15 + m∠14 = 180° (sum of angles in a straight line )
There are two angles m∠14 and m∠13 which are supplementary to angle 14.

In the figure, a∥e, m∥n, and m∠3 = 112°. What is the m∠1? Enter your answer in the box. ° Lines n and m (reading from top to bottom) are parallel to each other, and lines a and e are parallel to each other. The two pairs of lines intersect each other. Lines m and n start at top left and drop to the bottom right. Lines a and e rise from left to right. Only six of the sixteen angles created are labelled. Angle one is the top angle made by lines n and a. Angle two is the bottom angle. Angle three is the bottom angle made by lines m and a. Angle four is the top angle made by lines n and e. Angle five is the left angle. Angle six is the bottom angle made by lines m and e.
<1 = <2
vertical angles (congruent)
<3 = <2
corresponding angles (congruent)

Answer: w = -3/2u + 2
Step-by-step explanation: The independent variable, normally x, is not impacted by other variables. The problem is asking you to put the equation in w= form. W is the dependent variable while u is the independent variable (we’re used to seeing y= form, where x is independent and y is dependent. This is the same thing with different letters).
-12u + 13 = 8w - 3
-12u + 16 = 8w (add 3 to both sides)
(-12u + 16)/8 = w (divide both sides by 8)
-12/8u + 16/8 = w
-3/2u + 2 = w (simplify)
Answer: w = -3/2u + 2

A rectangular prism has a volume of 60 cubic centimeters. The height of the prism is 3 centimeters. What is the area of the base?
(Answer numerically only. Type fractions with / such as 1/2. Units have been provided)
_______Square Units
(This is all the problem gave me... so If you can pls help :D)
Answer: 20 cm ^2 (20 cm squared)
Step-by-step explanation:
This is a rectangular prism so Volume = Length(Width)(Height)
You only know the height and Volume so you do :
60 = L(W)(3) :then bring the 3 over:
60/3 = L(W)
20 = L(W)
Since area = L(W)
20 is your answer.
In science class, Jada uses a graduated cylinder with water in it to measure the volume of some marbles. After dropping in 4 marbles so they are all underwater, the water in the cylinder is at a height of 10 milliliters. After dropping in 6 marbles so they are all underwater, the water in the cylinder is at a height of 11 milliliters.
What is the volume of 1 marble?
How much water was in the cylinder before any marbles were dropped in?
What should be the height of the water after 13 marbles are dropped in?
Is the volume of water a linear relationship with the number of marbles dropped in the graduated cylinder? If so, what does the slope of the line mean? If not, explain your reasoning.
