This is not much of a question, because it doesn't take into account the width of the wood trim.  

So you are asked to find the perimeter of the window, ignoring the width of the trim.

P = Perimeter = 2L + 2W.

Here, P= 2(9 1/3 feet) + 2(6 3/4 feet) = 2(28/3 feet) + 2(27/4 feet)

So P = 2[28/3 + 27/4] feet.  LCD is 3*4 = 12.

Thus, P = 2 [ 28/3 + 27/4 ] feet.  Can you finish?  Add together the fractions 28/3 and 27/4.

The bake star bakery uses 2 1/4 cups of raisins to make 4 servings of trail mix. How many cups of raisins are in each serving?
Dima020 [189]

let's firstly convert the mixed fraction to improper fraction, and then divide it by 4 to see what our quotient is.


\bf \stackrel{mixed}{2\frac{1}{4}}\implies \cfrac{2\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{9}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{9}{4}\div 4\implies \cfrac{9}{4}\div \cfrac{4}{1}\implies \cfrac{9}{4}\cdot \cfrac{1}{4}\implies \cfrac{9}{16}

If N is a 3-digit integer, and the result of reversing the digits of N is the number M, what is the maximum value of N-M? Please
Lena [83]

Answer:

The maximum value of N-M will be 792

Step-by-step explanation:

For N - M to be maximum

N must be very large and M must be very small

largest 3 numbers occur in 900's and smallest 3 digit numbers occur in 100's

so we need such an N which starts with 9 and ends with 1 so that on reversing it produces a number starting with 1.

If N = 901 , M will be 109

N - M = 792

This is the largest possible value of N - M

All other values of N-M will give a smaller value than 792.

What percent of the 2019 world population lives in Canada? Round the percentage to three decimal places.
dimaraw [331]

0.486 % of world population lives in canada

<em><u>Solution:</u></em>

From given,

World population = 7691 million

Canada population = 37.4 million

We have to find the percent of world population lives in canada

Let "x" be the percent of world population lives in canada

Therefore, from question,

x % of world population = canada population

x % of 7691 = 37.4

<em><u>Solve the above equation for "x"</u></em>

x \% \times 7691 = 37.4\\\\\frac{x}{100} \times 7691 = 37.4\\\\7691x = 3740\\\\Divide\ both\ sides\ by\ 7691\\\\x = \frac{3740}{7691}\\\\x = 0.486

Thus 0.486 % of world population lives in canada

WILL GIVE BRAINLIEST!!!!
Svetradugi [14.3K]

Answer: 8 feet, D

Step-by-step explanation:

To solve this, use the Pythagorean Theorem. It states:

a^{2} +b^{2} =c^{2}

where A and B are the sides of a triangle and C is the triangle's hypotenuse.

The 17 foot ladder in this situation is your hypotenuse, and you have one side of the triangle: 15.

15^2 + b^2 = 17^2

15 squared = 225

17 squared = 289

solving for b squared, we get b^2 = 64

taking the square root of 64, you get 8 feet, the distance between the house and the base of the ladder.
