Question

During one waiters shift he delivered 13 appetizers, 17 entrées, and 10 desserts what percentage of the dishes he delivered were: A. Desserts B. Appetizers  C. entrees

Answer:

A)Desserts = 25 %

B)Appetizers = 32.5 %

C)Entrées =  32.5 %

Step-by-step explanation:

Given:

Number of appetisers = 13

Number of entrees =   17

Number of  desserts = 10

Solution:

Total number  of dishes = 13 + 17 + 10 = 40

percentage of the dishes he delivered were Desserts is   =  [tex]\frac{10}{40} \times 100 = 0.25 \times 100 = 25%[/tex]

percentage of the dishes he delivered were Appetizers is  =[tex]\frac{13}{40}\times 100 = 0.325 \times 100[/tex]  = 32.5%

percentage of the dishes he delivered were Entrées is = [tex]\frac{17}{40} \times 100 = 0.425 \times 100[/tex]=  42.5 %

To find the percentage of each type of dish a waiter has delivered, add up the total number of dishes, then divide the number of each type of dish by this total and multiply by 100.

The subject question requires us to determine what the percentage is of the various types of dishes a waiter delivers during his shift. We're given that the waiter delivered 13 appetizers, 17 entrees, and 10 desserts. We can solve this by doing some basic calculations:

First, we need to figure out the total number of dishes the waiter delivered. We do this by adding together the appetizers, entrees, and desserts he delivered: 13 appetizers + 17 entrees + 10 desserts = 40 dishes in total.

Next, to find the percentage of each type of dish, we divide the number of that type of dish by the total number of dishes, and then multiply the result by 100. For example, for appetizers: (13 appetizers / 40 total dishes) * 100 = 32.5%.

You can do the same calculations for entrees and desserts to find their percentages. These basic calculations are useful not only in a restaurant setting, but also in allocation of tasks in modern businesses and in many other real-world scenarios.

Answer:

C i think..

Step-by-step explanation:

When there's no number in front of a variable, that means it has a coefficient of 1.

So the coefficient is 1. Hope that makes sense.

The coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d is -1.

It is defined as the combination of constants and variables with mathematical operators.

We have an algebraic expression:

= 14a - 72r - c - 34d

From the above equation, the coefficient of the c term is:

= -1

Thus, the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d is -1.

Answer: The other answer is wrong. The answer would be about 50 miles per hour or 49.99 mph.

Step-by-step explanation:

The required approximate speed of the car when the skid mark is 10204 feet long is 49.99 miles per hour.

Given that,
The function S(D) =(7/2) √2D can be used to approximate the speed S, in miles per hour, of a car that has left skid marks of length D, in feet, how fast would a car have been traveling if it left a skid mark that is 102.04 feet long is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Given the function of speed,
S(D) =(7/2) √(2D)
Substitute the value of D = 102.04
S(102.04) = (7/2)√(2*102.04)
S(102.04) = 49.99

Thus, the required approximate speed of the car when the skid mark is 10204 feet long is 49.99 miles per hour.

Answer:

127.39 square units

Step-by-step explanation:

We are given;

We are supposed to determine its area;

Circumference = πD or 2πr , where D is the diameter and r is the radius

Thus;

40 = 2πr

πr = 20

 r = 20/π

Area of a circle is given by;

A = πr²

but, r = 20/π

Hence;

Area = π × (20/π)²

        = π × 400/π²

         = 400/π

Taking π to be 3.14

   Area = 400 ÷ 3.14

            = 127.39 square units

Thus, the area of the circle is 127.39 square units

Answer:

You'll need 18 cups of chicken broth!

Step-by-step explanation:

You are using a ratio of 1/4 cup (lentils) to 2 cup (broth). Therefore, you need to find the relationship between lentil and broth.

Therefore, 18 cups are needed :D

To make a soup with 2 1/4 cups of dried lentils, you would need 9 cups of chicken broth.

To find the number of cups of chicken broth needed, we need to multiply the given number of cups of dried lentils (2 1/4 cups) by the ratio of chicken broth to dried lentils. The ratio is 2 cups of chicken broth per 1/4 cup of dried lentils. So, for 2 1/4 cups of dried lentils, we would need:

2 1/4 cups × (2 cups/1/4 cup) = 9 cups of chicken broth

Answer:

Weekly allowance $4

Step-by-step explanation:

Fred ended with $11. So, subtract $9 from washing the car.

$11 - $9 = $2

$2 Is the amount of weekly allowance Fred hasn't spent yet. However, at the beginning of the week, Fred used half his allowance. This means $2 was what was left. So,

$2 × 2 = $4

meaning Fred had $4 in allowance at the beginning of the week.

The original price is $450.

Step-by-step explanation:

Step 1:

Given details, Discount%, D% = 30 and Selling Price, SP = $315

Step 2:

Write down formula for calculating the Original Price

Selling Price (SP) = Original Price (OP) - Discount (D)

Discount (D) = Original Price (OP) * (D%/100)

Step 3:

Substitute given values in the formula

315 = OP - D

D = [tex]OP \times30/100[/tex]

D = 0.3 OP

Step 4:

Substitute value of D in the first formula

315 = OP - 0.3 OP

315 = OP (1 - 0.3) = 0.7 OP

Original Price, OP = 315/0.7 = $450

Final answer:

Benjamin rides his scooter for a total of 6 miles over a period of 10 days, by multiplying the daily distance of 3/5 mile by 10 days.

Explanation:

To calculate the distance Benjamin rides his scooter over 10 days, we multiply the daily distance by the number of days. Benjamin rides 3/5 of a mile each day.

Distance per day = 3/5 mile
Number of days = 10 days

The total distance is:

3/5 mile/day × 10 days = 6 miles

Therefore, the correct answer is  Benjamin will have traveled a total of 6 miles over the course of 10 days.

Step-by-step explanation:

step 1

Find the area of Lauren's bedroom

Remember that the area of a rectangle is equal to

[tex]A=LW[/tex]

so

[tex]A=(18)(12)=216\ ft^2[/tex]

step 2

Find the area of closet

Remember that the area of a rectangle is equal to

[tex]A=LW[/tex]

so

[tex]A=(2)(4)=8\ ft^2[/tex]

step 3

Find the total area

Adds the areas

[tex]216+8=224\ ft^2[/tex]

step 4

Find the cost

Multiply the total area by the cost per square feet

so

[tex]224(4.15)=\$929.60[/tex]

Final answer:

The cost to carpet Lauren's bedroom including her closet is found by calculating the total area and then multiplying by the carpet's cost per square foot. The total area is 224 square feet and with a carpet cost of $4.15 per square foot, the total cost is $930.40.

Explanation:

To calculate the cost to carpet Lauren's room and closet, we must first determine the total area that needs to be carpeted. We already know that the room measures 18 feet by 12 feet. Taking the square footage of the room, we perform a multiplication: 18 ft  imes 12 ft = 216 square feet.

Next, we calculate the area of the closet separately, which measures 2 feet by 4 feet. The calculation would be 2 ft  imes 4 ft = 8 square feet. Now, we add the area of the room and the closet to get the combined area: 216 sq ft + 8 sq ft = 224 square feet.

Lastly, we find the cost to carpet this combined area. The carpet costs $4.15 per square foot, therefore, we multiply the total area by the cost per square foot: 224 sq ft  imes $4.15/sq ft = $930.40. So, the total cost to carpet Lauren's room and closet will be $930.40.

Answer:-12+6y

Step-by-step explanation:

Since the 12 is a negative and the 6y is a positive you can switch it around.

The expression 6y - 12 is equivalent to 6(y - 2). This can be verified by expanding the factored form, which results in the original expression.

This expression  can be factored to find an equivalent expression. Factoring out the greatest common factor (GCF) from both terms, we get:

Thus, the expression 6y - 12 is equivalent to 6(y - 2).
