Use the Law of Sines to solve for the variable. Round your answer to the
nearest whole number. Write the value only. *
Answer:
y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
[tex]\frac{y}{sin117}[/tex] = [tex]\frac{21}{sin18}[/tex] ( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )
y = [tex]\frac{21sin117}{sin18}[/tex] ≈ 61 ( to the nearest whole number )

What is the equation of the circle with a diameter whose endpoints are (-3,-9) and (-7,1)?
Answer:
12
Step-by-step explanation:
Answer:
( x + 5 )² + ( y + 4 )² = 29
Step-by-step explanation:
Equation of the circle is
( x - h )² + ( y - k )² = r²
( h, k ) are coordinates of the center
~~~~~~~~~~~~~~~~~~~~~
Coordinates of the center of the circle are
( [tex]\frac{-3-7}{2}[/tex] , [tex]\frac{-9+1}{2}[/tex] ) = ( - 5 , - 4 )

Sandy mixed together 9 gallons of one brand of juice and 8 gallons of a second brand of juice, which contains 48 percent real fruit juice. Find the percent of real fruit juice in the first brand if the mixture contained 30 percent real fruit juice. Which of the following equations could be used to solve this?
Group of answer choices
a(9)+48(8)17=0.30100
a(9)+0.48(8)17=30100
a(9)+0.48(8)a+0.48=30100
a(9)+0.48(8)17=30
Answer:
14 % pure juice comes from first brand
Step-by-step explanation:
Mixture:
17 gal 30% contains: 17x 30% = 5.10 gal pure juice
Second brand:
8 gal 48% contains: 8x40% = 3.84 gal pure juice
5.10 − 3.84 = 1.26 gal
1.26 gal is coming from 9 gal of first brand
The percentage of first brand is:
(1.26/9) x100 = 14 % pure juice.

How many factors of 10 are in 1000, only answer are three, two, four
Answer:
Step-by-step explanation:
The number 1000 has prime factors: 2, 2, 2, 5, 5, 5.
The factors of 1000 include 1 and combinations of these numbers multiplied together (in any arrangement):
1, 2*2*2*5*5*5 or 1, 1000
1*2, 2*2*5*5*5 or 2, 500
1*2*2, 2*5*5*5 or 4, 250
. . . (You already did these)
But, a “factor” is “a number or quantity that when multiplied with another produces a given number or expression,” so you should consider the following:
How many 1's? How many 5's? How Many 2's? [and any others ...]
1 = 1 0 0
2 = 1 0 1
4 = 1 0 2
8 = 1 0 3
5 = 1 1 0
10 = 1 1 1
20 = 1 1 2
40 = 1 1 3
25 = 1 2 0
50 = 1 2 1
100 = 1 2 2
200 = 1 2 3
125 = 1 3 0
250 = 1 3 1
500 = 1 3 2
1000 = 1 3 3

Match each expression on the left with an equivalent expression on the right.
The expression on the left matched with an equivalent expression on the right are;
3x + 0 = 3x
5/3 - x + 1/3 = -3/2x + 2 + 1/2x
2x - 3 = x - 3 + x
2x - 6 = -6 + 2x
3/5 - 13/5 = -6.9 + 4.9
How to solve equivalent expression?3x + 0 = 3x
5/3 - x + 1/3
combine like terms
= 5/3 + 1/3 - x
= (5+1)/3 - x
= 6/3 - x
= 2 - x
-3/2x + 2 + 1/2x
combine like terms
-3/2x + 1/2x + 2
= (-3+1)x / 2 + 2
= -2/2x + 2
= -x + 2
2x - 3 = x - 3 + x
2x - 6 = -6 + 2x
3/5 - 13/5
= (3-13)/5
= -10/5
= -2
-6.9 + 4.9
= -2

At a high school the average grade for the first semester for all subjects was 79.3. Based on this mean , the principal concludes that half of the grades were 79.3. Higher is her conclusion justified? Why or why not?
Answer:
That is incorrect. It would be appropriate if the median were 79.3, since the median is the value in the middle (when placing the data in order).
Conclusion of principal about mean is not justified. Mean represents the average of the data. For such conclusion mode is the correct option.
What is mean?
" Mean is defined as the ratio of the sum of all the given numbers in the data to the total numbers of numbers in the data. It is also known as average of the data."
What is mode?" Mode represents the value which occurs maximum numbers of times in the set of data."
According to the question,
Average grade for the first semester for all subjects = 79.3
Based on this mean
Principal concludes that half of the grades scored 79.3.
For example:
There are 5 students 3students score 100 , one student score 48 and another one got 50.
Mean of the class = [tex]\frac{398}{5}[/tex]
= 79.6
Here no student score 79.6.
Principal conclusion is not justified.
Mean is not the correct option to justify maximum number of students marks it is represented by mode.
Hence, conclusion of principal about mean is not justified. Mean represents the average of the data. For such conclusion mode is the correct option.

A report states that the mean household income last year for a certain rural county was $46,200 and the median was $54,500. If a histogram were constructed for the incomes of all households in the county, would you expect it to be skewed to the right, to the left, or approximately symmetric
Answer:
skewed to the left
Step-by-step explanation:
A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.
If the mean is greater than the median, the histogram would be skewed to the right
If the mean is less than the median, the histogram would be skewed to the left.
The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left

If using the method of completing the square to solve the quadratic equation x^2+5x+10=0x 2 +5x+10=0, which number would have to be added to "complete the square"?
Answer:
(5/2)² must be added to the equation to complete the square.
Step-by-step explanation:
The given equation is
x^2+5x+10=0
writing it in in square form
(x)² + 2(x) (5/2) + (5/2)²-(5/2)² + 10= 0
We multiply (5/2) to the mid term because we have to make 2x equal to 5x.
As the square formula tells that square of first element plus 2 into first element multiplied by second element plus square of second element.
Making 2x equal to 5x gives (5/2) as the second element.
Therefore add square of the second element but also subtract square of second element to make it equal to the given original equation.
Now we can solve it.
(x)² + 2(x) (5/2) + (5/2)²-(5/2)² + 10= 0
(x + 5/2)²-(5/2)² + 10= 0
(x + 5/2)²- 25/4+ 10= 0
(x + 5/2)²- 25*5 +10*5/4*5= 0
(x + 5/2)²- 125+50/20= 0
(x + 5/2)²- 175/20= 0
(x + 5/2)²= 175/20
