Answer:

let ratio be 5x,7x and 13x

we have

5x+7x+13x=180 sum of interior angle of the triangle is 180°

25x=180

x=180/25=36/5

Step-by-step explanation:

<em><u>m</u></em><em><u>i</u></em><em><u>s</u></em><em><u>s</u></em><em><u>i</u></em><em><u>n</u></em><em><u>g</u></em><em><u> </u></em><em><u>Angle</u></em><em><u> </u></em><em><u>a</u></em><em><u>r</u></em><em><u>e</u></em>

5x=5×36/5=<em><u>3</u></em><em><u>6</u></em><em><u>°</u></em>

7x=7×36/5=<em><u>5</u></em><em><u>0</u></em><em><u>.</u></em><em><u>4</u></em><em><u>°</u></em>

13x=13×36/5=<em><u>9</u></em><em><u>3</u></em><em><u>.</u></em><em><u>6</u></em><em><u>°</u></em>

What is/are the solution(s) of the system of equations? Why you say that is the solution? Write your answer in complete sentence
Alexus [3.1K]
Answer: The answer to a system of equations is the point(s) of intersection of the equation involved. 

When you have more than one equation with more than one variable, you have a system of equation. The solution(s) is the set of values for each variable that satisfy the equations. This means that the inputting values make the equations true.

A book sold 31,700 copies in its first month of release. Suppose this represents 8.8% of the number of copies sold to date. How
elena-14-01-66 [18.8K]

For this case we propose a rule of three:

31700 ------------> 8.8%

x ----------------------> 100%

Where "x" represents the number of copies sold to date.

x = \frac {100 * 31700} {8.8}\\x = \frac {3170000} {8.8}\\x = 360,227.273

Thus, to date 360,227 copies of the book have been sold.

ANswer:

To date, 360,227 copies of the book have been sold.

The volume of a right rectangular prism is given by:

Volume = (length)*(width)*(height)

Volume = (x)*(x)*((1/2)x)

Volume = (1/2)x^{3}

HELP!! hOW DO YOU FIND FREQUENCY FROM CLASS LIMITS AND CLASS BOUNDARY???? I AM SO CONFUSED.
GaryK [48]
<h3>Answer: See the image attached below for the filled out table</h3>

The third column is optional/extra. It's to show which data values fit in what specific class limit interval.

===================================================

Explanation:

Imagine we had a bunch of cards. Each card will have a number that is from the data set {70, 88, 103, 64, ... etc}

The goal is to sort the cards into 7 boxes. The first box is labeled "60 through 66", the next is "67 through 73", etc.

The first box has 4 cards placed inside it because we have the values {64,65,60,60 } which fit the interval from 60 through 66. Therefore the frequency here is 4.

The next box has the cards labeled {70,69,71,72,70 } inside it. We have 5 cards here, so the frequency is 5.

This pattern is kept up until all of the cards have been sorted into the proper boxes.

What you'll end up with is what you see in the image below. It shows the table of class limits with their corresponding frequencies. I have added a third column to show which values go where, which is optional and likely something you wont put as your answer to the teacher. This third column is just something for you to help keep track of everything.
