Atoms have Negatively charged particles called electrons and positively charged particle calls called protons if an atom loses an electron it has a positive electric charge if it gains an electron it has a negative electric charge which integer would represent the electric charge of an atom that has an equal number of electrons and protons?
Answer:
0
Step-by-step explanation:
This is because since the charge on the electron is negative while that on the proton is positive, also, the number of electrons equals the number of protons, this implies that the number of charges of electrons is equal and opposite to the number of charges of protons. This implies that their numbers are the inverse of each other. We know that the sum of a number and its inverse is zero, therefore, the electric charge on an atom with equal number of electrons and protons is thus zero.
So the integer that would represent this charge is zero, "0".

Explanation:
The two parallel lines form a parallelogram.
For any parallelogram, the opposite angles are congruent.
So the angle adjacent to P is also 106 degrees.
The adjacent angles add to 180
P+106 = 180
P = 180-106
P = 74

A consumer spends all of his money on two goods: apples and oranges. The consumer will pay $10 for apples, but only $1 for oranges. Why does the consumer pay more for apples?
Answer:
Step-by-step explanation:
Since no further information is given in this question the only reason a consumer would spend more on one item than the other is purely because of preference. The consumer in this scenario seems to enjoy eating or needs apples much more than he enjoys eating or needs Oranges. Therefore, he is ok with spending more money and getting a larger quantity of Apples than Oranges. This all depends on the demand that the individual has for a specific item over another item.

Complete question :
Leah loves chicken wings and is comparing the deals at three different restaurants. Buffalo Bills has 888 wings for \$7$7dollar sign, 7. Buffalo Mild Wings has 121212 wings for \$10$10dollar sign, 10. Wingers has 202020 wings for \$17$17dollar sign, 17. Which restaurant offers the lowest price per wing?
Answer:
Wingers ($0.85 per wing)
Step-by-step explanation:
Given the following :
Buffalo:
Price of 8 wings = $7
Price per wing :
Price sold / Number of wings :
$7/8 = $0.875
Buffalo Mild wings :
Price of 12 wings =$12
Price sold / Number of wings :
$12/12 = $1 per wing
Wingers :
Price of 20 wings = $17
Price sold / Number of wings :
$17/ 20 = $0.85
The lowest price per wing is offered by:
Wingers : $0.85 per wing
What is the measure , in degrees of the angle marked B?
Answer:
B = 142
Step-by-step explanation:
First, you need to find the angle of the third angle of the triangle. The three angles of a triangle always add up to 180, so it will be:
n + 77 + 65 = 180
= n + 142 = 180
= n = 38
Now, you need to find the angle supplementary to 38, as 38 and B are linear angles. Two supplementary angles add up to 180, so:
B + 38 = 180
= B = 142
The measure of the angle marked as B that is ABD in the given figure is equal to 142°.
Let us consider the vertices of the triangle are A, B , C
Where
measure of angle A = 77 degree
measure of angle C = 65 degree
Ray CB extends to Point D such that C-B - D.
Sum of all the interior angles in a triangle is equal to 180 degree.
Let measure of angle ABC be x degree.
m∠ABC + m∠BAC + m∠BCA = 180°
⇒ x° + 77° + 65° = 180°
⇒ x° + 142°= 180°
⇒ x° = 38°
Now angle ABC and angle ABD are linear pair.
m∠ABC + m∠ABD = 180°
⇒ 38° + m∠ABD = 180°
⇒ m∠ABD = 180° - 38°
⇒ m∠ABD = 142°
Therefore, measure of the angle marked as B is equal to 142°.

A car dealership manager has determined that the profit, in thousands of dollars, of the dealership can be determined by the expression LaTeX: x^2-4xL a T e X : x 2 − 4 x, where LaTeX: xL a T e X : x is the number of cars sold. A different manager states that the profit of the dealership can be determined by the function LaTeX: 5xL a T e X : 5 x. What number of cars sold makes the equation LaTeX: x^2-4x=5xL a T e X : x 2 − 4 x = 5 x true? Select all that apply.
Answer:
x = 0 ; x = 9
Step-by-step explanation:
Given that:
Manager 1 's profit function:
x² - 4x ; x = number of cars sold
Manager 2's profit function:
5x ; x = number of cars sold
Nunbers That makes the equation:
x² - 4x = 5x true
x² - 4x = 5x
Subtract 5x from both sides to make right hand side =. 0
X² - 4x - 5x = 5x - 5x
x² - 9x = 0
Using factorization to equate separate the x values.
x(x - 9) = 0
x = 0 or (x - 9) = 0
Hence,
x = 0 ; or
x - 9 = 0 ; x = 9
x = 0 OR x = 9
Number of cars sold which makes both managers have the same profit from the functions are either 0 or 9
In 2012, Grossfeld Company has net credit sales of $1,600,000 for the year.It had a beginning accounts receivable (net) balance of $108,000 and an ending accountsreceivable (net) balance of $120,000. Compute Grossfeld Company's (a) receivablesturnover and (b) average collection period in days.
Answer: a. 14.04; b. 26 days
Step-by-step explanation:
Net credit sales = $1,600,000
Beginning account receivable = $108,000.
Ending account receivable = $120,000
The Amaverage accounts receivables will be:
= ($108000 + $120000)/2
= $228000/2
= $114,000
Accounts Receivable turnover will then be calculated as:
= Net sales/Average accounts receivables
= $1600000/$114000
= 14.04
b) Average collection period will be calculated as:
= Number of days in a year/Accounts receivable turnover
= 365/14.04
= 25.997
= 26 days approximately

describe a real life multiplication situation for wich an estimate makes sense
Answer and step-by-step explanation:
Let's say for example that you want the circumference of a car tire to be a certain size, but the company only sells the measurements in the tire's radius. The formula for circumference is 2 * pi * r. We know that pi is not a rational number, so an estimate is required. The car tire you want is 6.5 inches in it's radius, and you want to see what the circumference is. Firstly, let's substitute the r in our equation. Then the equation becomes 2 * pi * 6.5. Then let's solve. Let's change our equation to 2 * 6.5 * pi to save the irrational part for last. Then our equation is 13 * pi. Lastly, let's round pi to 3.14, since we can only estimate its irrationalness. We get 40.82 inches. This is an example that you might use in real life while multiplying and estimating. I hope this helps, I hope it's not wrong, but I do not think it is.

What is the image of P(-8,4)?
What inequality represents this graph?
Answer:
x ≥ -8
General Formulas and Concepts:
If it is a closed dot, we use the inequality and equal sign: ≥ or ≤
If it is a open dot, we use the inequality only: > or <
Step-by-step explanation:
We can label the solutions as x.
We see starting from -8 that are solutions get larger.
Since the dot is closed, we use the greater than or equal to sign: ≥
Therefore, x has to be greater than -8 and increasing towards ∞.
x ≥ -8

The box below is 15 centimeters long, 4 centimeters wide, and 3 centimeters tall. What is the length of the diagonal s of the bottom side to the nearest tenth if necessary?
Answer:
The diagonal of the bottom side is 17.5 cm.
Step-by-step explanation:
The diagonal of a rectangle is a straight line that joins any two of its edges.
Given that: length = 15 cm, width = 4 cm, and h = 3 cm.
The bottom side is the flat rectangular surface (base) of length 15 cm and width 4 cm which excludes the height.
So that the diagonal, s, can be determined by Pythagoras theorem.
[tex]s^{2}[/tex] = [tex]17^{2}[/tex] + [tex]4^{2}[/tex]
= 289 + 16
= 305
s = [tex]\sqrt{305}[/tex]
= 17.46425
The diagonal of the bottom side is 17.5 cm.
