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 would a car have been traveling if it left a skid mark that is 102.04 feet long?
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.

Fred spent half of his allowance going to the movies. He washed the family car and earned 9 dollars. What is his weekly allowance if he ended with 11 dollars?
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.

his scooter if he rides 3/5mile
each day
for 10 days.
Answer:
Step-by-step explanation:
30/5=6
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.

a sign says that the price marked on all music equipment is 30% off the original price you buy an electric guitar for sale price of $315 what is the original price
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

Which expression is equivalent to 6y - 12
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:
6y and 12. The GCF is 6.Factor out the GCF: 6(y - 2).Thus, the expression 6y - 12 is equivalent to 6(y - 2).

To make a soup, 2 cups of chicken broth are needed for each 1/4 cup of dried lentils. How many cups of chicken broth are needed if 2 1/4 cups of dried lentils are used?
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.
In order to get from 1/4 to 2, you multiply by 8. (1/4 * 8 = 2)Therefore, the common relationship is multiplying the lentil amount by 8So, 2 1/4 * 8 = 18Therefore, 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.
Explanation: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

During one waiter's shift, he delivered 13 appetizers, 17 entrees, and 10 desserts. what percentage of the dishes he delivered were
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.
Explanation: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.

Lauren's bedroom measures 18 feet by 12 feet, with a closet that measures 2 feet by 4 feet. If carpet costs $4.15 per square foot, how much will it cost to carpet Lauren's room and closet?
Answer:
$929.60
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.

Find the area of the circle if it has a circumference of 40
Answer:
127.39 square units
Step-by-step explanation:
We are given;
Circumference of the circle as 40 unitsWe are supposed to determine its area;
The circumference of a circle is given by;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
