what is the absolute value of 2.3
The absolute value of any positive number is that number itself.
If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.
The absolute value is never negative. It represents distance from that value to 0 on the number line.
So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.
Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.
The required absolute number of 2.3 is also 2.3.
GIven that,
An absolute number of the value 2.3 is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The absolute number is defined as the outcome of the modulus function is called the absolute number or all natural numbers are examples of absolute numbers.
Here,
For the absolute value,
f(x) = |x|
f(2.3) = |2.3|
(since |x| = x or | -x | = x )
f( 2.3 ) = 2.3
Thus, the required absolute number of the value 2.3 is 2.3 itself.

Square root of 50 estimated to the nearest integer
Answer:
square root of 50 estimated to the nearest integer is, 7.1
Step-by-step explanation:
step 1. the square root of 50 is 7.07106781186548
step 2. reduce is 7.07
step 3. round 7.07 so you only have one digit after the decimal point to get the answer., 7.1
Answer:
7
Step-by-step explanation:
Consider perfect squares either side of 50, that is
49 < 50 < 64, thus
[tex]\sqrt{49}[/tex] < [tex]\sqrt{50}[/tex] < [tex]\sqrt{64}[/tex] , that is
7 < [tex]\sqrt{50}[/tex] < 8
Since 50 is nearer to 49 than it is to 64, then
[tex]\sqrt{50}[/tex] ≈ 7 ( to the nearest integer )
−8y−13=14y+11 what is the answer?
Answer:
y = -12/11
Step-by-step explanation:
-8y - 13 = 14y + 11
-8y - 14y = 11 + 13
-22y = 24
y = 24/-22
y = -12/11
Check:
-8*-12/11 - 13 = 14*-12/11 + 11
96/11 - 13 = -168/11 + 11
96/11 - 143/11 = -168/11 + 121/11 = -47/11
A store employee creates a display of sleds priced at $40 apiece. The store paid $32 for each sled. What is the mark-up percentage
Answer:
Mark-up percentage is 25%.
Step-by-step explanation:
From the question, the store bought each sled at $32 which is the cost price. The sled was display for sale at $40 apiece.
Mark-up percentage = [tex]\frac{selling price - cost price}{cost price}[/tex] x 100%
But,
selling price - cost price = $40 - $32
= $8
So that,
Mark-up percentage = [tex]\frac{8}{32}[/tex] x 100%
= 0.25 x 100%
= 25%
Therefore, the mark-up percentage is 25%.
Answer:
25%
Step-by-step explanation:
Your answer should be a polynomial in standard form.

Use distributive property
[tex]{ \sf{ {c}^{2} (2 {c}^{2} + 3c - 1) - 6(2 {c}^{2} + 3c - 1)}}[/tex]
[tex] \sf{2 {c}^{4} + 3 {c}^{3} - {c}^{2} - 12 {c}^{2} - 18c + 6}[/tex]
Collect like terms

Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Mia's test score (out of 50) if she got 3 questions wrong? What would be her score if she got x questions wrong?
Answer:
Mia's test score is 44 if she got 3 questions wrong.
Mia's test score is (50-2x) if she got x questions wrong.
Step-by-step explanation:
It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.
If she got 3 questions wrong, then
Deducted marks [tex]=2\times 3=6[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-6[/tex]
[tex]=44[/tex]
So, Mia's test score is 44 if she got 3 questions wrong.
If she got x questions wrong, then
Deducted marks [tex]=2\times x=2x[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-2x[/tex]
So, Mia's test score is (50-2x) if she got x questions wrong.

Use the law of conservation of momentum to determine the answer to the
flowing question: In this group, there are two hockey pucks, both with a mass of
0.25 kg. One is traveling at 2 m/s. The other is at rest. What is the momentum of
this group of objects?
Given :
Two hockey of same mass.
One is travelling at a speed of 2 m/s.
Other is in rest or 0 m/s.
To Find :
The momentum of this group of objects.
Solution :
Since , no external force is applied , so momentum will remains same :
Momentum of group of objects ,
[tex]M = mv_1^2+mv_2^2\\\\M = 0.25\times 2^2+0.25\times 0\\\\M=1 \ kg \ m/s[/tex]
Therefore , momentum of the system is 1 kg m/s.
Hence , this is the required solution.
Which equation does the graph below represent?
y = 1 x
y = 4x
y = _ 1x
y = -4x
Answer:
Y=-4x
Step-by-step explanation:
Whenever you solve for slope, and the slope is 1, never write 1 in the equation. Write either -x or x. Let's take two coordinates, one which is (0, 0), which is the origin, and (1, -4). To find the slope, we insert the first coordinate and second coordinate values into the equation (Y2-Y1)/(X2-X1). We can insert these coordinates to get (-4 - 0)/(1 - 0), which simplifies to (-4)/1, which further simplifies to -4. Since the Y-intercept is zero, there is no value of B in the equation, which leaves the equation as Y=-4x

Thanks
The equation for break even is 8P = 48
What is an Equation ?An equation is an expression that states the equality of two things expressed in different form.
In the given question
Conard spent $48 for art supplies
Canvas costs $2
He plans to sell his painting for $10
∴ Without the canvas his paintings costs $(10 - 2)
= $8
So, no. of paintings (P) to break even he needs to sell
8P = 48
P = 6
∴ Conard needs to sell 6 paintings to break even.
