A local computer store sold 82 laptops this past month. Since the store first opened, it has sold 76 times that number. How many laptops has the store sold since it opened?
a. 5,412
b. 6,232
c. 6,192
d. 5,952
The store has sold 6,232 laptops since it opened.
Option B is the correct answer.
We have,
Step 1:
Identify the number of laptops sold last month.
The problem states that the store sold 82 laptops in the past month.
Step 2:
Determine the total number of times the store has sold laptops since it opened.
The problem says that the store has sold 76 times the number of laptops sold last month.
So, we need to multiply 82 by 76.
82 laptops * 76
= 6,232 laptops
Thus,
The store has sold 6,232 laptops since it opened which is option B.

Answer: 1/6
Step-by-step explanation:
First, you have a 1/3 chance of picking 1. Second, you have only 2 and 3 left, which means you have a 1/2 chance of picking a number less than 3. Since you have to multiply these two probabilities, and 1/3x1/2=1/6, the answer is 1/6. Hope this helps!

Need answer asap, will give brainly if its right
Answer: 36 inches (in.)
Step-by-step explanation:
The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).
We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.
We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.
Input the given values into the formula and you get the following:
\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)
\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)
\(36 +x =39\)
\(x=3\)
Therefore, the length from the ball to the hole is 3 feet (ft.).
BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.
Therefore, the distance from the ball to the hole is 36 inches (in.).

Step-by-step explanation:
Chuin has 18 coins in his pocket. He has nickels and dimes that total $1.45. How many nickels and how many dimes does he have? Write and solve a system of equations to find the answer.
A. 10 Nickles, 8 dimes
B. 9 nickles, 9 dimes
C. 8 nickles, 10 dimes
D. 7 nickles, 11 dimes
Answer:
D
Step-by-step explanation:
Let n represent the number of nickels and d represent the number of dimes Chuin has.
Since Chuin has a total of 18 coins in his pocket, the sum of the number of nickels and dimes must total 18. So:
\(n+d=18\)
The total worth of the coins is $1.45. Since each nickel is worth $0.05 and each dime is worth $0.10:
\(0.05n+0.1d=1.45\)
Solve the system. We can use elimination (you can use substitution if you prefer, it works just as perfect!). First, multiply both sides of the second equation by 10:
\(0.5n+d=14.5\)
Next, we can multiply the first equation by negative one:
\(-n-d=-18\)
Add the two equations together:
\((0.5n+d)+(-n-d)=(14.5)+(-18)\)
Simplify:
\(-0.5n=-3.5\)
Divide both sides by -0.5. So:
\(n=7\)
Chuin has seven nickels.
Using the first equation again, substitute n for 7 and solve for d:
\((7)+d=18\Rightarrow d=11\)
Therefore, Chuin has seven nickels and 11 dimes.
Our answer is D.

By matching the statistical measures with their corresponding values, we have:
Median: 23.5
Mean: 22.5
Mode: 20, 24, 25, 26
Lower Quartile: 21.5
Upper Quartile: 24.5
To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:
Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.
Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.
Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.
Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.
Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

Use the figure to find the measures of the numbered angles. For 95 and explain how?
Answer:
Angle 3 is 95 degrees because it is in a corresponding position to the 95 degrees, and lines A and B are parallel. Angle 4 is 85 degrees because it has to be supplementary to angle 3.
95+85=180
Answer:
Angle 4 is 85°
Step-by-step explanation:
Because the lines are parallel the angles are congruent, you can find the supplementery angles when one angle is given by subtracting 180° by the angle given unless they are alternate interior angles. If they are alternate interior angles to the angle given then the angle willbe congruent to the original.

Answer: You would swap the ineqaulity
Step-by-step explanation:
Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.
