The system of inequalities to determine the number of hamburger and hotdog buns Mr. Wu should purchase is x \\geq 2y for the quantity requirement, and 0.45x + 0.40y \\leq 60 for the budget constraint.
To determine how many hamburger buns (x) and hotdog buns (y) Mr. Wu can purchase for the concession stand, we need to set up a system of inequalities based on the given conditions. Since he needs at least twice as many hamburger buns as hotdog buns, we can express this requirement as an inequality: x \\geq 2y. Additionally, considering the cost of hamburger buns is $0.45 each and hotdog buns are $0.40 each, the total spending should not exceed $60. This gives us a budget constraint inequality: 0.45x + 0.40y \\leq 60. Therefore, the system of inequalities that can be used to determine the number of each kind of bun Mr. Wu should purchase is:
x \\geq 2y0.45x + 0.40y \\leq 60Which is equivalent to “12 chairs for every 3 tables”?
Answer:
A 12 chairs per 3 table
Step-by-step explanation:
4/1 is equivalent to 12 chairs for every 3 tables.
What is fraction?Fractions are used to represent smaller pieces (or parts) of a whole.
Given a statement, 12 chairs for every 3 tables.
The statement represents 12 chairs per 3 tables, which means 12/3 = 4/1
Therefore, there are 4 chairs for every table.
Hence, 4/1 is equivalent to 12 chairs for every 3 tables.

What is the next number in the series? 83 79 75 71 67 ?
Answer:
Given the series : 83 , 79 , 75 , 71 , 67, ?
Difference of two consecutive terms;
79 -83 = -4
75 -79 = -4
71-75 = -4
67-71= -4
Since, you can see that the number is decreases by 4 every time.
Let unknown term be x
then;
x - 67 = -4
x = 67-4
x = 63.
Therefore, the next term in the series is 63.
The next number in the series is 63.
In the given series, each number is decreasing by 4.
We can observe that the first number, 83, is decreased by 4 to get the next number, 79.
Similarly, each subsequent number is obtained by subtracting 4 from the previous number.
Following this pattern, the next number would be obtained by subtracting 4 from the last number in the series, which is 67.
67 - 4 = 63
Therefore, the next number in the series is 63.

"apply quickselect to find the median of the list of numbers 9, 12, 5, 17, 20, 30, 8."
Final answer:
To find the median using quickselect, choose a pivot value, partition the list, and repeat the process with the appropriate partition until the pivot index matches the desired median index.
Explanation:
The median of a list of numbers is the middle value when the numbers are arranged in ascending order. To apply quickselect to find the median, start by choosing a pivot value from the list. Partition the list and move all values smaller than the pivot to the left and all values larger than the pivot to the right. If the pivot index is equal to the desired median index, then the pivot value is the median. Otherwise, if the pivot index is smaller, repeat the process with the right partition; if the pivot index is larger, repeat with the left partition.
In the given example, let's apply quickselect to find the median:
Choose a pivot value, let's say 17.
Partition the list: 5, 8, 9, 12, 17, 20, 30
The pivot index is 4, which is less than the desired median index.
Repeat the process with the right partition: 17, 20, 30
Choose a new pivot value, let's say 20.
Partition the list: 17, 20, 30
The pivot index is 1, which is equal to the desired median index.
Therefore, the median of the list of numbers 9, 12, 5, 17, 20, 30, 8 is 17.

On a resent business trip it took 7 hours 30 minutes to drive 375 miles how many miles per hour was the average
Answer:
50 miles / hours.
Step-by-step explanation:
Speed may be defined as the distance covered by the object per unit time.
Speed = [tex]\frac{distance}{time}[/tex]
the distance of the business trip = 375 miles.
the time taken by the business trip = 7 hours 30 minutes = 7.5 hrs.
Speed = [tex]\frac{375}{7.5}[/tex]
Speed = 50 miles / hours.
Here, the average of miler per hour is 50 miles / hours.

a) Find the depreciation equation.
b.) Value
Value
Depreciation is defined as the reduction in value of an asset over time. In this case, value reduction is due to wear and tear of an equipment (bicycle).
a. The depreciation value would simply be the difference in initial and salvage value divided by time in years.
Depreciation = (Initial value – Salvage value) / Number of years
b. Substituting the given values into the equation where:
Initial value = $1200
Salvage value = $940
Number of years = 10 months = 10/12 years
Calculating:
Depreciation = ($1200 - $940) / (10/12 years)
Depreciation = $312 / year
or
Depreciation = $26 / month

The scores on an exam are normally distributed, with a mean of 74 and a standard deviation of 7. What percent of the scores are less than 81?The scores on an exam are normally distributed, with a mean of 74 and a standard deviation of 7. What percent of the scores are less than 81?
We are given the following variables:
Normal distribution
u = sample mean = 74
s = standard deviation of the samples = 7
x = sample value = 81
Since we are asked to find percent of the scores less than 81, this means we have to find the proportion using the z-score. The formula for z score is:
z = (x – u) / s
Substituting the given values:
z = (81 – 74) / 7
z = 1
Using the standard normal distribution tables for z, we find that:
P = 0.8413 at z = 1
Therefore this means that 84.13% of scores are less than 81.

A businessman has 10 employees. His salary is equal to 6 times the average of employees salaries. If the 11 of them receive a total of $64,000 in one year, what was the business mans salary that year ??
x = business man's salary
y = employee's salary
x + 10y = 64000
x = 6y
6y + 10y = 64000
16y = 64000
y = 64000/16 = 4000
x = 6*4000
x = 24000
business man's salary was $24,000

In △ABC, m∠A=72°, c=61, and m∠B=16°. Find a to the nearest tenth.
Using the law of sines, the length of side a to the nearest tenth is 58.1 units.
What is law of sines?Law of sines states that When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C.
In ΔABC,
∠A=72°
∠B=16°
∠A + ∠B + ∠C = 180° (angle sum property)
72° + 16° + ∠C = 180°
∠C = 180° - (72° + 16°) = 92°
Using sine law, (refer to the figure attached)
[tex]\frac{sin\ A}{a} = \frac{sin\ B}{b} =\frac{sin\ C}{c} \\\\\frac{sin72}{a} = \frac{sin16}{b} = \frac{sin92}{61} \\\\\frac{sin72}{a} =\frac{sin92}{61} \\\\a = sin72 * \frac{61}{sin92} \\\\= 0.9511 * \frac{61}{0.9994} \\\\=58.05193116\\\\= 58.1[/tex]
