Find the missing side lengths.
Step-by-step explanation:
let x be the missing side length.We know that hypotenuse is 2x because x is opposite the 30 angle.
Using pythagorean theorem we have that x^2+9^2=(2x)^2
81=4x^2-x^2
81=3x^2
x^2=81/3=27
x=√27
so the missing side is √27

HAIR BUNDLES: B'UNIQUE Hair Salon owner buys seven hundred bags of a brand of synthetic hair bundles and four hundred bags of a brand of natural hair bundles for her Forestville and Largo locations to get ready to welcome back their clients for her reopening this weekend. The Forestville location receives three hundred bags of synthetic hair bundles and two hundred and fifty bags of natural hair bundles for a total retail value of twenty-three thousand, six hundred dollars. The Largo location receives four hundred bags of a brand of synthetic hair bundles and one hundred and fifty bags of a brand of natural hair bundles for a total retail value of twenty-four thousand, five hundred dollars. What is the retail value of one bag of a synthetic hair bundle and one bag of a natural hair bundle. In your answer, write a system of equations of how you would determine your answer. Provide evidence of your calculations and answer your result in a complete sentence.
Answer:
The retail value of one bag of one bag of a synthetic hair bundle is $47 and the retail value of a bag of natural hair bundle is $38
Step-by-step explanation:
The given information are;
The number of bags of synthetic hair bundles the owner buys = 700
The number of bags of natural hair bundles the owner buys = 400
The number of synthetic hair bundles the Forestville location receives = 300
The number of natural hair bundles the Forestville location receives = 250
The total retail value of the hair bundles the Forestville location receives = $23,600
The number of synthetic hair bundles the Largo location receives = 400
The number of natural hair bundles the Forestville location receives = 150
The total retail value of the hair bundles the Largo location receives = $24,500
Let the price of a bag of synthetic hair bundle = x
Let the price of a bag of natural hair bundle = y
∴ 300·x + 250·y = $23,600...(1)
400·x + 150·y = $24,500...(2)
Making y the subject of the formula in both equations gives;
For equation (1)
y = 23,600/250 - 300/250·x = 94.4 - 1.2·x
y = 94.4 - 1.2·x
For equation (2)
400·x + 150·y = 24,500
y = 24,500/150 - 400/150·x = 490/3 - 8/3·x
y = 490/3 - 8/3·x
Finding the common solution gives;
490/3 - 8/3·x = 94.4 - 1.2·x
490/3 - 94.4 = 8/3·x - 1.2·x
1034/15 = 22/15·x
x = 1034/15/(22/15) = 47
x = 47
∴ The price of a bag of synthetic hair bundle = x = $47
The price of a bag of synthetic hair bundle = $47
y = 490/3 - 8/3·x = 490/3 - 8/3 × 47 = 38
y = 38
The price of a bag of natural hair bundle = y = $38
The price of a bag of natural hair bundle = $38.
Therefore, the retail value of one bag of one bag of a synthetic hair bundle is $47 and the retail value of a bag of natural hair bundle is $38.

A teacher gathered data about the number of hours her students spent studying for a test and their resulting test grades. She found that on average, for every 30 minutes studied, the grade increased by 8 points. Which statements about this relationship are true? Check all that apply.
The data set would have a linear association.
The data set would have a nonlinear association.
The data set would have a positive correlation.
The data set would have a negative correlation.
Every student earns 16 more points for each additional hour they study.
Students that study more tend to earn better grades on the test.
The scenario described exhibits a linear relationship between the number of study hours and test grade as seen in the constant rate of change in grade per increase in study hours. Hence, the following statements are true ;
The data set would have a linear association.The data set would have a positive correlation.Students that study more tend to earn better grades on the test.Since test grade tends to increase as the number of study hours increases, these shows that there is a positive relationship between the variables. Hence, students who take in more hours of study tend to have better test grade.
