Find the values of x and y. Write your answers in the simplest form.
Answer: [tex]x=18[/tex] ; [tex]y=6\sqrt{3}[/tex]
Step-by-step explanation:
You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.
Pythagorean's Theorem:
The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.
[tex]a^2+b^2=c^2[/tex]
[tex]x^2+y^2=(12\sqrt{3} )^2[/tex]
[tex]x^2+y^2=12^2*\sqrt{3} ^2=432[/tex]
Sine of the Angle:
Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:
[tex]sin(\alpha )=opposite/hypotenuse[/tex]
[tex]sin(30)=y/12\sqrt{3}[/tex]
[tex]\frac{1}{2} =y/12\sqrt{3}[/tex]
[tex]y=6\sqrt{3}[/tex]
Plug this value of 'y' into the first expression derived from Pythagorean's theorem:
[tex]x^2+y^2=432[/tex]
[tex]x^2+(6\sqrt{3} )^2=432[/tex]
[tex]x^2+108=432[/tex]
[tex]x^2=432-108=324[/tex]
[tex]x=\sqrt{324}[/tex]
[tex]x=18[/tex]
Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:
[tex](\sqrt{324})^2+y^2=432[/tex]
[tex]324+y^2=432[/tex]
[tex]y^2=432-324=108[/tex]
[tex]y=\sqrt{108}[/tex]
[tex]y=\sqrt{36*3}[/tex]
[tex]y=6\sqrt{3}[/tex]

In the sample, there are 4 more students with brown hair and blue eyes than blond hair and blue eyes.
How many total students have black hair?
=======================================================
Explanation:
x = total number of students surveyed
According to the table, 0.075 of the students (aka 7.5%) have blond hair and blue eyes. This means 0.075x is the number of blond hair blue eye people.
Also, 0.125x is the number of brown hair blue eye people for similar reasoning as the previous paragraph.
We're told that "There are 4 more students with brown hair and blue eyes than blond hair and blue eyes"
So,
(BrownHair_BlueEyes) = (BlondHair_BlueEyes) + 4
0.125x = (0.075x) + 4
0.125x-0.075x = 4
0.05x = 4
x = 4/0.05
x = 80
There are 80 students surveyed.
Of those eighty students, 0.075x = 0.075*80 = 6 have blond hair and blue eyes; while 0.125x = 0.125*80 = 10 have brown hair and blue eyes. Notice how this is four more than the blond person count with blue eyes. This confirms we have the correct sample size.
The last step is to calculate how many of the students have black hair based on the sample size we just found.
The table shows 25% = 0.250 of the students have black hair, so 0.25x = 0.25*80 = 20 students have black hair

Tristan is comparing two number patterns based on the information below.
Both patterns start with the number 1.
Pattern A follows the rule “add 3”.
Pattern B follows the rule “add 4”.
How does each of the first 5 terms in Pattern A compare to the first 5 terms in Pattern B?
As part of your answer, list the first 5 terms of each pattern.
Explain your answer.
Pattern A = 1, 4, 7, 10, 13
Pattern B = 1, 5, 9, 13, 17
Each term is increases at a faster rate in pattern B; the difference between terms increases by one per step. In pattern A, 1 jumps to 4, while in pattern B, 1 jumps to 5. There is a difference of one. But when in pattern A, 4 jumps to 7, in pattern B, 5 jumps to 9. The is a difference of two between these two terms even though they are on the same "jump." This difference increases by one per "jump." (Jump is not the official word for this but I'm assuming this isn't a sequence problem.)

Miguel cut 1/4 from a round pie. Mariah cut a piece from the same pie with an angle measure of 60 degrees who cut the larger piece? Explain.
Answer: Since the pie is round it is a circle, and all circles have 360 degrees in total. Miguel cut 1/4 of the pie and 1/4 x 360 = 90. 90 is greater than 60.
Step-by-step explanation:
Answer:
Miguel has the larger piece. 1/4 is equal to 90, because 360/4 = 90.
So Miguel has the larger piece

A total of 590 tickets were sold for the school play. They were either adult tickets or student tickets. There were 60 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
325 adult tickets
Step-by-step explanation:
This "sum and difference" problem can be solved by assigning a single variable to the quantity you want to know. Let 'a' represent the number of adult tickets sold. Then (a-60) is the number of student tickets sold, and the total number sold is ...
a +(a -60) = 590
2a = 590 +60
a = 650/2 = 325
There were 325 adult tickets sold.
__
Check
325-60 = 265 student tickets were sold, for a total of 325+265 = 590.
_____
Additional comment
You may have noticed that the larger number of tickets (number of adult tickets) was found to be the average of the two numbers given in the problem statement. That will generally be the case for a "sum and difference" problem.

Answer:
y=-x2 - 8x – 18 is shown by graph D.
y=x2 - 4x + 7 is shown by graph A.
y=X+5 is shown by graph C.
y=-3x - 6 is shown by graph B.
Step-by-step explanation:
In y=-x2 - 8x – 18, the coefficient of x2 is less than 0.So the graph only has a maximum value.Thefore , the graph is point upward.
In y=x2 - 4x + 7, coefficient of x2 is greater than 0.
So the graph has a minimum point and is pointed downward.
for y =x + 5, the gradient is positive.so it is graph C.There is another way to find out too but this is quicker for now.
for y = -3x - 6, the gradient is negative ,-3.So it is the graph B.

Answer:
1. 83 square inches
2. 7.065 square centimeters
Step-by-step explanation:
Hey there!
In order to find the area of the shaded region of the rectangle, you need to first find the area of the whole shape
The dimensions are 10 and 16 and if you multiply them together, you get 160
This means that the area of the whole shape is 160
Now they are asking for the area of the shaded shape, so we need to find the area of the white rectangle, and then subtract that area from 160
The dimensions for the white rectangle is 11 and 7
This means that the area of the white rectangle is 77
Now what we need to do is subtract 77 from 160
160-77=83
So the area of the shaded region is 83 square inches
Now to get to the second question
We need to find the area of the quarter circle
In order to find this, we need to first find the area of the whole circle, then divide that by 2
They gave us the radius already which makes it a lot easier (the radiues is 3)
All we need to do is input 3 into the formula for the area of a circle
[tex]\pi r^2[/tex]
In this case, since they are telling us to use 3.14 as pi, the equation would look like this:
[tex]3.14*3^2[/tex]
This can be simplified to [tex]3.14*9[/tex] which is equal to 28.26
So this is the area of the whole circle
But the question is asking for the area of a quarter of that circle
So what we need to do is divide 28.26 by 4 which is 7.065
So the area of the quarter circle is 7.065 square centimeters
1. Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
weekly raise= $145
solution:let's assume the first paycheck as x.
she got a weekly raise of $145.
So, after concluding the first week she'll get $ (x+145).
likewise, after completing the second week she'll get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
therefore, this is how her salary will get increased by $145 at the end of every week.

If we try: 4) x = 16 y = 116...
[tex]\sqrt{116^2 - 16^2} = 20\sqrt{3} \neq 10[/tex]
If we try: 2) x = 16 y = 29...
[tex]\sqrt{29^2 - 16^2} = 3\sqrt{65} \neq 10[/tex]
If we try: 1) x = 4 y = [tex]2\sqrt{29}[/tex]...

the sum of the digits of a two - digit number is 14 . if the digits are reversed, the number increases by 36 . find the number .
Let the tens digit of the number be x .
ones digit = ( 14 - x ) ( since the sum of the 2 digits is 14 )
Two - Digit number = 10 ( tens digit ) + ones digit
Required number ,
10x + ( 14 - x ) 10x - x + 14 9x + 14Reversed number ,
10 ( 14 - x ) + x 140 - 10x + x 140 - 9xGiven ,
Reversed number - Required number = 36
✯ 140 - 9x - ( 9x + 14 ) = 36
✯ 140 - 9x - 9x - 14 = 36
✯ 126 - 18x = 36
✯ 126 - 36 = 18x
✯ 18x = 90
✯ x = 5
Ten digits , x = 5 Ones digits = ( 14 - x ) = 14 - 5 = 9♧ Thus , Required number is 10 × 5 + 9 = 59
Given -
the sum of the digits of a two - digit number is 14.i.e, if two numbers are x and y then, x + y = 14
if the digits are reversed, the number increases by 36i.e, if 10y + x then 10y + x = 10x + y + 36.
To find -
the numberConcept -
If a, b and c are real number (and if a and b both are not equal to 0) then ax+by=c is called a linear equation in two variables (The two variables are x and y)
The numbers a and b are called the coefficient of the equation ax+by=c. The number r is called the constant of the equation ax+by = c
PS - first we will construct two linear equations and then we'll find the number.
Solution -
Let, x + y = 14
➜ y = 14 - x ----(i)
and we'll solve 10y + x = 10x + y + 36 further,
➜ 10y + x = 10x + y + 36
➜ 10y - y = 10x - x + 36
➜ 9y = 9x + 36
➜ 9x - 9y = -36
➜ 9(x - y) = -36
➜ x - y = -4 ----(ii)
Substituting the value of y (in equation (i)) in equation (ii),
➜ x - (14 - x) = -4
➜ x - 14 + x = -4
➜ 2x = -4 + 14
➜ 2x = 10
➜ x = 10/2
➜ x = 5
Now to find the value of y we will substitute the value of x in equation (i),
➜ y = 14 - 5
➜ y = 9
Therefore, the number is {10(5)+9,i.e,} 59.
