Answer:
16 feet.
Step-by-step explanation:
Given:
Ben’s living room is a rectangle measuring 10 yards x 168.
Question asked:
How many feet does the legs of the room exceed the width ?
Solution:
By applying unitary method:
Length of rectangle = 10 yards = 30 feet (1 yard = 3 feet)
(10 yard = [tex]3\times10 = 30)[/tex]
Breadth of rectangle = 168 inch = 14 feet (12 inch = 1 feet)
(1 inch = [tex]\frac{1}{12}[/tex])
( 168 inch = [tex]\frac{1}{12}[/tex][tex]\times168 = 14 feet)[/tex]
By subtracting the breadth from the length of rectangle,
30 feet - 14 feet = 16 feet
Therefore, by 16 feet, length of the room exceed the width.

How is the Distributive Property used to simplify operations with scientific notation
Answer:
See explanation
Step-by-step explanation:
Let a,b, and c be real numbers.
The distributive property says that:
[tex]a(b + c) = ab + ac[/tex]
Assuming we want to simplify:
[tex]10(5*10^{-1}+150*10^{-3})[/tex]
We apply the distributive property to get:
[tex]10(5*10^{-1}+150*10^{-3}) = 5*10^{-1} \times 10+150*10^{-3} \times 10[/tex]
We can now use rules of exponents to simplify further:
[tex]10(5*10^{-1}+150*10^{-3}) = 5*10^{-1} \times 10^{1} +150*10^{-3} \times 10^{1} [/tex]
[tex]10(5*10^{-1}+150*10^{-3}) = 5*10^{-1 + 1} +150*10^{-3 + 1}[/tex]
[tex]10(5*10^{-1}+150*10^{-3}) = 5*10^{0} +150*10^{-2}[/tex]
[tex]10(5*10^{-1}+150*10^{-3}) = 5*1+1.50*10^{-2}x {10}^{2} [/tex]
[tex]10(5*10^{-1}+150*10^{-3}) = 5*1+1.50*10^{-2 + 2}[/tex]
[tex]10(5*10^{-1}+150*10^{-3}) = 5+1.50*10^{0} = 6.5 \times {10}^{0} [/tex]
Each pair of polygons is similar. Find the values of x and y
x = 14 and y = 10
Explanation:Two shapes are similar if they have the same form but not necessarily the same size. In other words, when shapes are similar they are in proportion. Since you haven't provided any diagram, I'll choose two irregular polygon that are similar as indicated in the figure below. So we can calculate both x and y with proportions as follows:
[tex]For \ x: \\ \\ \frac{x}{7}=\frac{16}{8} \\ \\ x=\frac{7\times 16}{8} \\ \\ x=14 \\ \\ \\ For \ y: \\ \\ \frac{y}{20}=\frac{8}{16} \\ \\ y=\frac{8\times 20}{16} \\ \\ y=10[/tex]

21. Higher Order Thinking Amil and Abe
rode in a bike-a-thon. Abe rode for 77 minutes
at a faster rate per mile than Amil. Find Amil's
unit rate. Then explain how you could use it to
find a possible unit rate for Abe.
Amil rode 15 miles
in 55 minutes.
Amil's unit rate is calculated by dividing the distance traveled (15 miles) by the time in hours (0.917 hours), resulting in approximately 16.36 mph. Abe's unit rate is faster but cannot be precisely determined without more information about his distance or time.
Explanation:Amil rode 15 miles in 55 minutes. To find Amil's unit rate, we divide the total distance by the total time. The unit rate is a measure of speed, indicating how many miles are traveled in one minute. To find this unit rate, we perform the following calculation:
Convert the time from minutes to hours to find the unit rate in miles per hour (mph), since speed is often expressed this way: 55 minutes × (1 hour/60 minutes) = 0.917 hours
Divide the distance by the time: 15 miles ÷ 0.917 hours = 16.36 mph (rounded to two decimal places).
Amil's unit rate is approximately 16.36 mph. This information can be used to estimate Abe's unit rate, knowing that Abe rode at a faster rate. If we knew how far Abe rode or his unit rate in miles per minute, we could compare the two directly. Without additional information about Abe's distance or time, we can only say that Abe's unit rate exceeds 16.36 mph.

World: 7,691
Canada: 37.4
What percent of the 2019 world population lives in Canada? Round the percentage to three decimal places.
Answer:
0.486% of world population lives in Canada.
Step-by-step explanation:
Given: World Population= 7691 million.
Canada Population= 37.4 million.
Now, finding the percentage of world population lives in Canada.
[tex]Population\ percentage= \frac{Canada\ population}{World\ population} \times 100[/tex]
⇒ [tex]Population\ percentage= \frac{37.4}{7691} \times 100[/tex]
⇒ [tex]Population\ percentage= 0.00486\times 100[/tex]
∴ [tex]Population\ percentage= 0.486\%[/tex]
Hence, 0.486% of world population lives in Canada.

Whats the answer to. 4r + 8 + 5 = -15 - 3r
To solve the equation 4r + 8 + 5 = -15 - 3r, combine like terms and isolate the variable r leading to the solution r = -4.
Explanation:The student is asking how to solve the algebraic equation 4r + 8 + 5 = -15 - 3r. To solve for r, we must first simplify and combine like terms. This means we need to get all the terms with r on one side of the equation and the constant numbers on the other side.
Therefore, the solution to the equation is r = -4.
Final answer:
The solution to the equation 4r + 8 + 5 = -15 - 3r is r = -4.
Explanation:
The algebraic equation provided by the student is 4r + 8 + 5 = -15 - 3r.
To solve for r, we must first simplify and rearrange the equation by combining like terms and moving the variables to one side and the constants to the other.
By subtracting 3r from both sides and also subtracting 8 + 5 from both sides, we end up with 4r + 3r = -15 - 8 - 5. Simplifying further, we get 7r = -28.
Finally, dividing both sides by 7 yields r = -4.

Marco buys a certain brand of shampoo from a supplier at 7.25 dollars per bottle .He sells it at a markup of 25 percent. What is the markup .
Final answer:
Marco buys shampoo at $7.25 per bottle and sells it with a 25% markup, making the markup $1.81 per bottle. The selling price, therefore, is $9.06 per bottle.
Explanation:
The question is about calculating the markup applied by Marco on a bottle of shampoo. Marco buys the shampoo at $7.25 per bottle and sells it at a markup of 25 percent. The markup is calculated based on the cost price of the product. In this case, to find the markup amount, we use the formula: Markup = Cost Price * Markup Percentage. So, the markup on each bottle of shampoo is $7.25 * 0.25 = $1.81. Therefore, Marco applies a $1.81 markup on each bottle of shampoo.
To determine the selling price, one can add the markup to the cost price, which would be $7.25 + $1.81 = $9.06. This is Marco's selling price per bottle after applying the 25 percent markup.

what is the vertex of the quadratic function below y=3x^2-12x+17
Answer:
(2, 5 )
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 3x² - 12x + 17 ← is in standard form
with a = 3 and b = - 12, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-12}{6}[/tex] = 2
Substitute x = 2 into the function for corresponding value of y
y = 3(2)² - 12(2) + 17 = 12 - 24 + 17 = 5

On a scale drawing the scale is 1/2 inch=1 foot what are the dimensions on the scale drawing for a room that is 22 feet by 17 feet
Hey there! I'm happy to help!
We have a room that is 22 by 17 feet. We know that for every foot, we draw a 1/2 inch. This means that we need multiply our dimensions by 1/2 to find the dimensions of the drawing.
22×1/2=11
17×1/2=8.5
Therefore, the dimensions of the room are 11 feet by 8.5 inches. These are the dimensions of a normal white paper!
Have a wonderful day! :D
To convert the actual room dimensions of 22 feet by 17 feet to a scale drawing with a scale of 1/2 inch equals 1 foot, the length becomes 11 inches, and the width becomes 8.5 inches in the drawing.
When creating a scale drawing, the dimensions of the actual room need to be converted into scale dimensions. According to the scale given, which is 1/2 inch equals 1 foot, the actual room dimensions of 22 feet by 17 feet should be converted using this scale ratio.
To do this conversion, each actual dimension must be divided by the scale factor. The scale factor is determined by the number of feet that are represented by 1/2 inch. Since 1/2 inch is equivalent to 1 foot, the scale factor is 1 foot per 1/2 inch. Therefore, we calculate the dimensions as follows:
Length: 22 feet / 1 foot per 1/2 inch = 22 x 1/2 inches = 11 inches
Width: 17 feet / 1 foot per 1/2 inch = 17 x 1/2 inches = 8.5 inches
Thus, the dimensions on the scale drawing for a room that is 22 feet by 17 feet would be 11 inches by 8.5 inches.
The age of Noelle’s dad is 6 less than 3 times Noelle’s age. The sum of their ages is 74 . Find their ages.
Answer: Noelle's age is 20 years
Noelle's father is 54 years
Step-by-step explanation: First of all, let Noelle's age be represented by x. Given that her father's age is 6 less than three times her age, her father's age would be expressed as
3n - 6
Note also that their ages sum up to 74.
Therefore,
n + (3n - 6) = 74
n + 3n - 6 = 74
4n - 6 = 74
Add 6 to both sides of the equation
4n = 80
Divide both sides of the equation by 4
n = 20
Hence, Noelle's father's age is 54 (that is 3n - 6)
While Noelle's age is 20
Noelle’s age is 20
her dads age is 54
