if the cost of goods sold was $42,000 the income from sales was $86,000 and the expenses were $12,000 find gross profit and net profit
Gross profit is $44,000 and Net profit is $32,000
Step-by-step explanation:
Given :
cost of goods sold = $42,000The income or revenue = $86,000expenses = $12,000Gross profit :
Gross Profit = Total income - Cost of goods sold
⇒ $86,000 - $42,000
⇒ $44,000
⇒ Gross profit is $44,000
Net profit :
Net profit = Gross profit – Total Expenses
⇒ $44,000 - $12,000
⇒ $32,000
⇒ Net profit is $32,000
a card is randomly chosen from a standard deck of cards. Find each probability.
Answer: The probability is 1/52 or .0192.
Step-by-step explanation:
A standard deck of cards has 52 so the probability of picking 1 card would be 1/52.
(a) The probability of drawing a spade is 1/4.
(b) The probability of drawing a face card (jack, queen, or king) is 3/13.
(c) The probability of drawing a red card is 1/2.
(d) The probability of drawing a card that is not an ace is 12/13.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
(a) The probability of drawing a spade.
There are 13 spades in a standard deck of 52 cards, so the probability of drawing a spade is:
P(spade) = 13/52 = 1/4
(b) The probability of drawing a face card (jack, queen, or king).
There are 12 face cards (4 jacks, 4 queens, and 4 kings) in a standard deck of 52 cards, so the probability of drawing a face card is:
P(face card) = 12/52 = 3/13
(c) The probability of drawing a red card.
There are 26 red cards (13 hearts and 13 diamonds) in a standard deck of 52 cards, so the probability of drawing a red card is:
P(red card) = 26/52 = 1/2
(d) The probability of drawing a card that is not an ace.
There are 48 cards that are not aces in a standard deck of 52 cards (there are 4 aces), so the probability of drawing a card that is not an ace is:
P(not ace) = 48/52 = 12/13
Thus,
(a) The probability of drawing a spade is 1/4.
(b) The probability of drawing a face card (jack, queen, or king) is 3/13.
(c) The probability of drawing a red card is 1/2.
(d) The probability of drawing a card that is not an ace is 12/13.

Which choices are equivalent to the quotient below? Check all that apply. √12/√6
The expression (√12) / (√6) simplifies to √2 by combining square roots and simplifying the fraction. The final simplified form is √2. Here option A is correct.
Given Expression:
(√12) / (√6)
Step 1: Write as Quotient of Square Roots
(√12) / (√6) can be expressed as √(12/6)
We express the division of square roots as the square root of the division of the radicands.
Step 2: Simplify the Quotient Under the Radical
√(12/6)
To simplify the fraction under the square root, divide the numerator by the denominator:
√(12/6) = √2
Step 3: Write the Answer in Simplified Form
√2
Therefore, the given expression (√12) / (√6) simplifies to √2.
We simplified the expression by combining the two square roots into one using the rule for dividing square roots and then simplified the fraction under the square root to arrive at the final answer, which is √2. Here option A is correct.
The correct option is A and C.
The equivalent choices to the given quotient [tex]\(\frac{\sqrt{12}}{\sqrt{6}}\)[/tex] are A [tex](\(\sqrt{2}\))[/tex] and C [tex](\(\frac{\sqrt{4}}{\sqrt{2}}\))[/tex].
The question shows a math problem asking which choices are equivalent to the given quotient:
[tex]\[ \frac{\sqrt{12}}{\sqrt{6}} \][/tex]
We'll solve this step by step:
1. Simplify the square roots by factoring out squares:
[tex]\[ \sqrt{12} = \sqrt{4 \cdot 3} = \sqrt{4} \cdot \sqrt{3} = 2\sqrt{3} \][/tex]
[tex]\[ \sqrt{6} = \sqrt{2 \cdot 3} = \sqrt{2} \cdot \sqrt{3} \][/tex]
2. Write the original quotient with the simplified square roots:
[tex]\[ \frac{\sqrt{12}}{\sqrt{6}} = \frac{2\sqrt{3}}{\sqrt{2} \cdot \sqrt{3}} \][/tex]
3. Cancel out the common terms:
[tex]\[ \frac{2\sqrt{3}}{\sqrt{2} \cdot \sqrt{3}} = \frac{2}{\sqrt{2}} \][/tex]
4. Rationalize the denominator by multiplying the numerator and denominator by [tex]\(\sqrt{2}\)[/tex]:
[tex]\[ \frac{2}{\sqrt{2}} \cdot \frac{\sqrt{2}}{\sqrt{2}} = \frac{2\sqrt{2}}{2} \][/tex]
5. Simplify the fraction:
[tex]\[ \frac{2\sqrt{2}}{2} = \sqrt{2} \][/tex]
So the simplified quotient is [tex]\(\sqrt{2}\)[/tex]. Now let's check the options in the image to see which ones are equivalent to [tex]\(\sqrt{2}\)[/tex]:
A. [tex]\(\sqrt{2}\)[/tex] - This is the correct simplified form of the given quotient.
B. [tex]\(2\)[/tex] - This is incorrect because it is not the square root of 2.
C. [tex]\(\frac{\sqrt{4}}{\sqrt{2}}\)[/tex] - Since [tex]\(\sqrt{4} = 2\)[/tex], this simplifies to [tex]\(\frac{2}{\sqrt{2}}\)[/tex], which after rationalization becomes [tex]\(\sqrt{2}\)[/tex], so this is also correct.
D. [tex]\(\frac{2}{\sqrt{3}}\)[/tex] - This is incorrect because it does not simplify to [tex]\(\sqrt{2}\)[/tex].
E. [tex]\(\frac{\sqrt{6}}{\sqrt{2}}\)[/tex] - Since [tex]\(\sqrt{6} = \sqrt{2 \cdot 3}\)[/tex], this simplifies to [tex]\(\sqrt{3}\)[/tex], which is incorrect.
F. [tex]\(\frac{\sqrt{6}}{2}\)[/tex] - This does not simplify to [tex]\(\sqrt{2}\)[/tex] and is therefore incorrect.
The correct answer choices are A and C, which are both equivalent to [tex]\(\sqrt{2}\)[/tex].

Which number line represents all of the values of x for the equation x2 = 25?
Answer:
x = 5 and x = -5
Step-by-step explanation:
Given x^2 = 25, we take the square root of both sides. The two solutions are x = 5 and x = -5
The values for x in the equation x2 = 25 are 5 and -5. These solutions are represented on a number line at points 5 and -5.
Explanation:The equation x2 = 25 can be solved by taking the square root of both sides of the equation. When we take the square root of a number, we get two possibilities: a positive and a negative value, since squaring a number always results in a positive number. Therefore, the values for x in the given equation would be x = 5 and x = -5.
On a number line, these points would be represented at the 5 and -5 positions. Therefore the number line that represents all the values of x for the equation x2 = 25 is the one that includes both -5 and 5. Keep in mind that no other numbers would satisfy the equation x2 = 25.

The quotient of d minus 16 and 3 is 4 . Which equation shows this ?
Answer: d-16/3=4
Step-by-step explanation: thats the equation!
hope it helps please mark brainliest
Final answer:
The equation representing the statement "The quotient of d minus 16 and 3 is 4" is (d - 16) / 3 = 4. By solving the equation, we find that d = 28.
Explanation:
The question asks to find the equation that represents the statement: "The quotient of d minus 16 and 3 is 4." This translates to a mathematical equation by dividing the difference of d and 16 by 3, which equals 4. The equation that shows this relationship is (d - 16) / 3 = 4.
To solve this equation for d, you can follow these steps:
Multiply both sides of the equation by 3 to eliminate the denominator: (d - 16) = 12.
Add 16 to both sides of the equation to solve for d: d = 12 + 16.
This gives you d = 28 as the solution.
Therefore, the equation that accurately represents the given statement is (d - 16) / 3 = 4, and the value of d that satisfies this equation is 28.

Ariana and two friends decide to split a pizza and garlic bread. If the total cost for the food is $15.33, how much should each person pay?
Answer: $7.665 each, approximately $7.67 each
Step-by-step explanation:
If cost is $15.33
To be sharedby two friends will be the cost/2
15.33/2= $7.665 each
Each person should pay $5.11 to equally split the total cost of the pizza and garlic bread, which is $15.33.
The student is asking how to divide the total cost of a pizza and garlic bread, which is $15.33, evenly among three people. To calculate this, we can use simple division.
Here is the step-by-step calculation:
First, identify the total cost of the food: $15.33.
Next, determine the number of people sharing the cost, which is three.
Divide the total cost by the number of people: $15.33 ÷ 3 = $5.11.
Therefore, each person should pay $5.11 to equally split the cost of the pizza and garlic bread.
Find a linear function that models the data in the table.
f(x)= *blank* x + *blank*
The linear function that models the data in the table is [tex]\( f(x) = 2x + 3 \)[/tex].
Explanation:To find the linear function, we need two key pieces of information: the slope mn and the y-intercept b. In the given function f(x) = 2x + 3, the coefficient of x (2) represents the slope, and the constant term (3) represents the y-intercept.
The slope m indicates the rate at which the function is changing, and in this case, it is 2. This means that for every unit increase in x, y increases by 2 units. The y-intercept b is the value of y when x is zero, which is 3 in this case. Therefore, the linear function f(x) = 2x + 3 accurately models the relationship between x and y in the given dat x in a linear manner.
In summary, the general form of a linear function is [tex]\(f(x) = mx + b\)[/tex], where m is the slope and b is the y-intercept. The values of m and b can be determined from the data or information provided.
The linear function that models the data in the table is [tex]\(f(x) = \frac{13}{7}x + 1\)[/tex], where x represents the input and f(x) the output.
To find a linear function that models the data in the table, we can use the slope-intercept form of a linear equation: f(x) = mx + b, where m is the slope and b is the y-intercept.
Let's find the slope (m) first using the given data points (-4, -6) and (3, 7):
[tex]\[m = \frac{\text{change in } y}{\text{change in } x} = \frac{7 - (-6)}{3 - (-4)} = \frac{13}{7}.\][/tex]
Now that we have the slope, we can use any point from the table to find the y-intercept (b). Let's use the point (0, 1):
[tex]\[1 = m(0) + b \implies b = 1.\][/tex]
Now, we can write the linear function:
[tex]\[f(x) = \frac{13}{7}x + 1.\][/tex]
So, the linear function that models the data in the table is [tex]\(f(x) = \frac{13}{7}x + 1\)[/tex].

?
The range of the data set is 67 pounds.
Explanation:The range of a data set is the difference between the maximum and minimum values. In this case, the weights of the 7 dogs are 66, 8, 12, 74, 36, 66, and 7 pounds. To find the range, we subtract the smallest value (7) from the largest value (74):
Range = 74 - 7 = 67
So, the range of the data set is 67 pounds.

2(v+1)>0⋅(3)
and again Simplify the left side.
Apply the distributive property.
2v+2⋅1>0⋅(3)
Multiply 2 by 1
2v+2>0⋅(3)
Multiply 0 by 3
2v+2>0
Subtract 2 from both sides of the inequality.
2v>−2
Divide each term by 2 and simplify.
Getting the conclusion where V is greater than 1
v>−1

Ben goes to the grocery store at a rate of 7 times a week. To find out how many times he goes in 17 weeks, you multiply 7 by 17, which equals 119. Therefore, Ben is expected to go to the grocery store 119 times in 17 weeks.
Explanation:
To calculate how many times Ben goes to the grocery store in 17 weeks, given that he goes at a rate of 7 times a week, we need to multiply the number of weeks by the frequency of his visits per week. The calculation is as follows:
Multiply the number of visits per week by the number of weeks: 7 visits/week imes 17 weeks. Perform the multiplication: 7 imes 17 = 119. Therefore, Ben is expected to go to the grocery store 119 times in 17 weeks.
