Answer:
225 chairs
Step-by-step explanation:
Let the number of chairs ordered that cost $20 each be x and the number of chairs that cost $40 each is y.
Total cost= 20x +40y
Given that the company bought $6000 worth of chairs,
20x +40y= 6000
Dividing both sides by 20:
x +2y= 300 ----- (1)
x= 2y -----(2)
Substitute (2) into (1):
2y +2y= 300
4y= 300
y= 300 ÷4
y= 75
Subst. y= 75 into (2):
x= 2(75)
x= 150
Total number of chairs ordered
= x +y
= 150 +75
= 225

In ΔJKL, j = 8.1 inches, ∠K=160° and ∠L=14°. Find the length of l, to the nearest 10th of an inch.
Answer:
18.7
Step-by-step explanation:
First find the degree of J which is 6 (found this by doing 180=160+14=6
so then you make the fraction J/sin14=8.1/sin6
cross multiply so its Jsin6=8.1sin14
to get J by itself you divide by sin 6 so
J=8.1sin14 divided by sin6 which equals 18.7
The length of [tex]l[/tex] is approximately 18.8 inches.
In this question we know the value of two angles, in sexagesimal degrees, and a length of the triangle, in inches, we must determine the length [tex]l[/tex] by the law of sine:
[tex]\frac{l}{\sin \angle L} = \frac{j}{\sin \angle J}[/tex] (1)
[tex]\angle J = 180^{\circ} - \angle K - \angle L[/tex] (2)
If we know that [tex]j = 8.1\,in[/tex], [tex]\angle K = 160^{\circ}[/tex] and [tex]\angle L = 14^{\circ}[/tex], then the length of [tex]l[/tex] is:
[tex]\angle J = 180^{\circ}-160^{\circ}-14^{\circ}[/tex]
[tex]\angle J = 6^{\circ}[/tex]
[tex]l = j\cdot \left( \frac{\sin \angle L}{\sin \angle J} \right)[/tex]
[tex]l = (8.1\,in)\cdot \left(\frac{\sin 14^{\circ}}{\sin 6^{\circ}} \right)[/tex]
[tex]l \approx 18.8\,in[/tex]
The length of [tex]l[/tex] is approximately 18.8 inches.

Which one is the right answer?
Answer:
the answer is C
Step-by-step explanation:
magazine = $4.99
book = $12.99
DVD = $17.99
total bill
= magazine + book + DVD
= $4.99 + $12.99 + 17.99
= $35.97
tax 6%
amount of tax
= 6% × total price
= 6/100 × $35.97
= $2.16
total bill including 6% tax
= total bill + amount of tax
= $35.97 + $2.16
= $38.13

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?
Answer:
A. The data set would have a linear association.
C. The data set would have a positive correlation.
E. Every student earns 16 more points for each additional hour they study.
F. Students that study more tend to earn better grades on the test.
Step-by-step explanation:
Since in the question it is mentioned that the teacher obtained data with regard to the number of hours that students spent for their test and on their results. She found that on an average for each 30 minutes studied, the graded would rise by 8 points
Now this kind of relationship represents the linear association, positive correlation and study more earn better
Therefore the above three statements are true
