A restaurant manager can spend at most $400 a day for operating costs and payroll. It costs $100 each day to operate the bank and $50 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most: 50x + 100 ≤ 600

Answer:

Your tip was $7.25 so you payed a total of $36.25 on your $29 bill.

Answer:

$36.25

Step-by-step explanation:

Multiply 29.00 by 0.25 to get 25% of 29.00. You would get 7.25. Then add the 25% tip to the dinner amount (29.00+7.25) and you would get 36.25.

Answer:

F, I’m not sure but i would go with F since you want the original cost or rather “c”, you want to divide that to get the $5.50 which it states that that’s the half price.

Answer:

Step-by-step explanation:

sale price = $5.50

(1/2) or 50% off the price.

let c = original price

c/2 = 5.50

c = $11

so the answer is F.

Answer:

a)  About 46.3 hours

b) About $1036.80

Step-by-step explanation:

a)

Break even means to make enough to cover her costs.

Given her cost is 1000, we need to find how many hours she will need to cover this up.

In 1 minute, she can type 90 words, that would pay her:

0.004 per word for 90 words = 0.004 * 90 = $0.36 per minute

Susan makes $0.36 per minute, so the amount of time (in minutes) it will take her to make $1000, is:

1000/0.36 = 2777.78 minutes

Converting that to hours, we divide by 60,

2777.78/60 = 46.3 hours

b)

4 hours per day for 3 days = 4 * 3 = 12 hours (per week)

Let there be 4 weeks in a month, so

12 hours per week * 4 = 48 hours per month

She will work 48 hours per month.

Given 90 words per minute, in 1 hour, she can type:

60 minutes * 90 = 5400 words per hour

In 48 hours, she can type:

5400 words per hour * 48 hours = 259,200 words

That would pay her:

0.004 per word for 259,200 words = 0.004 * 259,200 = $1036.80

Step-by-step explanation:

7×2=14

The two numbers are -20 and -82. By creating two equations x + y = -102 and x = y - 62, substitute for x in the first equation and solve for y, then substitute y back into the second equation to solve for x.

To solve the problem, you can create two equations using the given information.

You can now substitute the equation from step 2 into equation 1:

(y - 62) + y = -102.

Combine like terms:

2y - 62 = -102.

Then add 62 to both sides of the equation:

2y = -40.

Finally, divide both sides by 2:

y = -20.

Substitute y = -20 back into x = y - 62:

x = -20 - 62 = -82.

Step-by-step explanation:

The graph that best represents the described temperature change is Graph A.

The description provided suggests a graph of temperature change over time.

In the morning, the temperature starts around 50°F, so the initial point on the graph would be at (0, 50). As the day progresses, the temperature rises first slowly and then more quickly, indicating a steeper slope.

After reaching a peak, the temperature stays constant for an hour, suggesting a flat line parallel to the x-axis.

Finally, the temperature drops slowly, indicating a decreasing slope.

Based on this description, Graph A represents the temperature change over the day.

The only prime number that is a factor of 16 is 2, since 16 is a power of 2 (2⁴).

The student has asked to identify the only prime number that is a factor of 16. To find the factors of 16, we can break it down into its prime factors. The prime factorization of 16 is 2×4×4, which reduces further to 2×2×2×2 or 24. Since the prime factors of 16 are all 2s, the only prime number that is a factor of 16 is 2. It's important to note that a prime number is defined as a number that has exactly two distinct positive divisors: 1 and the number itself. In the case of 16, 2 is the only prime number that fits this definition and is a factor.

Answer:

106 slices left

Step-by-step explanation:

To solve this we need to multiply 19 and 6:

19 * 6 = 114

there was 114 slices of pizza

next subtract 114 and 8

114 - 8 = 106

there was 106 slices of pizza left after Miguel ate 8 slices of pizza

Final answer:

After calculating the total slices from 19 pizzas and subtracting the 8 slices consumed by Miguel, there are 106 pizza slices left for the rest of the French Club.

Explanation:

The student asked about the number of pizza slices left after Miguel ate some. To calculate this, we first need to find the total number of slices in 19 pizzas, each cut into 6 slices, and then subtract the 8 slices that Miguel ate.

Calculate the total number of slices: 19 pizzas × 6 slices/pizza = 114 slices.

Subtract the slices Miguel ate: 114 slices - 8 slices = 106 slices.

So, there are 106 pizza slices left for the rest of the French Club.

Answer:

  232 square feet

Step-by-step explanation:

The outside dimensions of the yard are 26 ft by 36 ft, so its total area is ...

  yard including walk = (26 ft)(36 ft) = 936 ft²

The dimensions of the yard inside the walkway are 22 ft by 32 ft, so that area is ...

  yard not including walk = (22 ft)(32 ft) = 704 ft²

The difference in these areas is the area of the walkway:

  walkway area = (yard including walk) - (yard not including walk)

  = (936 -704) ft² = 232 ft² . . . . area of the walk

_____

Another way to figure this is to consider the length of the centerline of the walkway. That is the perimeter of a rectangle that is 24 ft by 34 ft. The perimeter (centerline length) is 116 ft, and the width of the walk is 2 ft, so its area is ...

  (116 ft)(2 ft) = 232 ft²

Answer:

[tex]59.19 ft^2[/tex]

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=7.2\ ft[/tex]

[tex]\pi =3.14[/tex]

substitute

[tex]A=(3.14)(7.2)^{2}[/tex]

[tex]A=162.78\ ft^2[/tex]

step 2

we know that

The area of a circle subtends a central angle of 2π radians

so

using proportion

Find out the area of a sector with a central angle of 8 π/11 radians

[tex]\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2[/tex]

Final answer:

The area of a sector with a central angle of 8π/11 radians and a radius of 7.2 ft, using 3.14 for π, is approximately 78.60 ft² when rounded to the nearest hundredth.

Explanation:

To calculate the area of a sector of a circle, we use the formula ½ θr², where θ is the central angle in radians, and r is the radius of the circle. For a sector with a central angle of ₈π/₁₁ radians and a radius of 7.2 ft, substituting 3.14 for π, we can find the area as follows:

Use the formula: Area = (½)(θ)(r²).

Substitute the given values to get: Area = (½)(₈π/₁₁)(7.2 ft)².

Calculating using 3.14 for π we get: Area = (0.5)*(8*3.14/11)*(7.2 ft)².

Simplify and calculate the result which gives us: Area = 78.5952 ft².

Round the final answer to the nearest hundredth: Area = 78.60 ft².

Answer:

Step-by-step explanation:

The mean score on this test is 8.8, and the median score is 9.4.

In order to find the mean of the scores, we use the formula:

[tex]\[ \text{Mean} = \frac{\sum (X \cdot f)}{N} \][/tex]

where X is the score, f is the frequency, and N is the total number of scores. Applying this formula to the given data:

[tex]\[ \text{Mean} = \frac{(4 \cdot 1) + (5 \cdot 1) + (6 \cdot 1) + (7 \cdot 2) + (8 \cdot 1) + (9 \cdot 5) + (10 \cdot 5)}{1 + 1 + 1 + 2 + 1 + 5 + 5} \][/tex]

[tex]\[ \text{Mean} = \frac{4 + 5 + 6 + 14 + 8 + 45 + 50}{15} \][/tex]

Mean = [tex]\frac{132}{15}[/tex]

Mean = 8.8

So, the mean score is 8.8.

To find the median using the formula:

[tex]\[ \text{Median} = L + \frac{\frac{N}{2} - F}{f} \times w \][/tex]

where:

- L is the lower class boundary of the median group,

- N is the total number of observations,

- F is the cumulative frequency of the group before the median group,

- f is the frequency of the median group,

- w is the width of the median group.

First, arrange the data and calculate cumulative frequencies:

Test Score  Frequency     Cumulative Frequency

3                    0                      0

4                      1                      1

5                      1                     2

6                       1                     3

7                       2                     5

8                       1                      6

9                       5                     11

10                     5                     16

The median position is [tex]\( \frac{N}{2} = \frac{16}{2} = 8 \)[/tex]  with a score of 9. The cumulative frequency before the median group is 6, and the frequency of the median group is 5.

Now, using the formula:

Median= 9 + [tex]\frac{8 - 6}{5} \times 1[/tex]

Median= 9 + [tex]\frac{2}{5}[/tex]

Median = 9 + 0.4

Median = 9.4

Therefore, the median score is 9.4.

Final answer:

To find the equation of a line that is parallel to a given line and passes through a specific point, use the fact that parallel lines have the same slope. Find the slope of the given line, substitute the slope and the point into the slope-intercept form of a line to find the y-intercept, and write the equation with the new slope and y-intercept.

Explanation:

To find the equation of a line that is parallel to a given line and passes through a specific point, we need to use the fact that parallel lines have the same slope. The given line, y = -2x + 7, has a slope of -2. So, the parallel line we need to find will also have a slope of -2.

Now, we can use the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept. Since we know the slope is -2 and the point (4,1) lies on the line, we can substitute these values into the equation to find the y-intercept:

y = -2x + b

1 = -2(4) + b

1 = -8 + b

b = 9

Therefore, the equation of the line that passes through (4,1) and is parallel to y = -2x + 7 is y = -2x + 9.

Answer:

4 + x = 16

Step-by-step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."
