ANSWER:
tan(30⁰)=√3/3
cos(30⁰)=√3/2
switch sides:sin(x) /√3/2 =√3/3
multiply both sides by 3:3·sin(x) /√3/2 =3·√3/3
simplify:2√3 sin (x) =√3
divide both sides by 2√3:2√3 sin (x) / 2√3 = √3 / 2√3
simplify:sin (x)= 1/2

The perimeter of a square is 80 - 64y units.Which expression can be used to show the side length of one side of the square.
A. 16(5-4y).Each side measures 5-4y units
B. 16y(5-4y) Each side measures 5-4 y units
C. 4(20-16y)Each side measures 20-16y units
D 4y(20-16)Each side measures 20-16 units
Answer A. 16(5-4y).Each side measures 5-4y units
Step-by-step explanation:
Answer:
Option C is correct
4(20-16y) each side measures 20-16y units
Step-by-step explanation:
The distributive property says that:
The perimeter(P) of a square is given by:
.....[1]
As per the statement:
The perimeter of a square is 80-64y units
we can write this as:
Apply the distributive property we have;
⇒P = 4(20-16y)
On comparing with [1] we have;
Each Side length = 20-16y units
Therefore, an expression can be used to show the side length of one side of the square is, 4(20-16y) each side measures 20-16y units

What is the increasing and decreasing
9514 1404 393
Answer:
decreasing: (-∞, -3)increasing: (-3, ∞)Step-by-step explanation:
The leading coefficient is positive, so you know the parabola opens upward.
The ratio -b/(2a) is -6/(2·1) = -3, so you know the axis of symmetry is x = -3. The function will be decreasing from negative infinity to the vertex at x = -3, and will be increasing from there to positive infinity. At the vertex (x=-3), the function is neither increasing nor decreasing.
decreasing: (-∞, -3)increasing: (-3, ∞)_____
Additional comment
For ax^2 +bx +c, the axis of symmetry is x=-b/(2a). The vertex (turning point) is on the axis of symmetry.

What are the variables in the expression 2w + 11t + 4y
A 2, 11, and 4
B w, t, and y
C 17
D 2w, 11t, and 4y
9514 1404 393
Answer:
B. w, t, and y
Step-by-step explanation:
Delete the numbers and the math operators and what you have left are variables. You will want to eliminate any duplicates from the list (there aren't any duplicate).
The variables are w, t, y.
Answer:
Option BStep-by-step explanation:
Definition of variables: Variables are terms that have no coefficients.
To look for variables in the expression 2w + 11t + 4y, simply look for the variables (letters) in the expression. We can see that the variables are w, t, and y, which matches Option B.
Hence, Option B is correct.
Andrew borrowed $700 from the bank to start a pressure washing business. The bank charged a simple interest rate of 7% per year. If it takes Andrew 3 years to pay back the loan, how much interest will he pay?
Answer:
$147Step-by-step explanation:
Given:
Loan amount = $700Interest rate = 7% simpleTime = 3 yearsInterest amount:
$700*3*0.07 = $147Answer:
Simple interest=(Principal×Rate×Time)/100
Principal=$700, Rate=7%, & Time=3 years
→S.I. = (700×7×3)/100 = 147
Andrew has to pay a interest of $147.

C. A different class is made up of 68% women and has 19 women in it. What is the total number of students in the class?
Answer:
a. 44.19%
b. 127
c. 28
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
The required answers are-
a. The percentage of male in the class is 44.18%.
b . There are 127 men in the class.
c. Total number of students in the class are 28.
What is percentage?A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.
a. The percentage of male in the class :
Now its given that,
Number of males = 19
Number of females = 24
Total students = 43
Percentage of males = Number of males/Total students *100%
⇒ Percentage of males = 19/43 *100%
⇒ Percentage of males = 44.18%
So,The percentage of male in the class is 44.18%
b . men in the class
It is given that,
Total students = 259
Percentage of males = 49%
Number of males in the class = 49% of 259
⇒ Number of males in the class = 49/100 *259
⇒ Number of males in the class = 126.91 ≈127
So,There are 127 men in the class.
c. Total number of students in the class
It is given that,
Percentage of women = 68%
Number of women = 19
Let x be the number of women in the class.
So,
68% of x = 19
⇒ 0.68x = 19
⇒ x = 19/0.68
⇒ x = 27.94
⇒ x ≈ 28
Hence,Total number of students in the class is 28
Thus, the required answers are-
a. The percentage of male in the class is 44.18%.
b . There are 127 men in the class.
c. Total number of students in the class are 28.

BA² = AC² - BC²BA = √AC² - BC²BA = √4.7² - 4.1² = √5.28 = 2.3 cm (rounded)Answer:
Let the required side (=BA) be x meter
According to the problem, (using the Pythagorus Theorem)
[tex] {x}^{2} + ({4.1)}^{2} = {(4.7)}^{2} \\ {x}^{2} = {(4.7)}^{2} - {(4.1)}^{2} \\ {x}^{2} = (4.7 + 4.1)(4.7 - 4.1) \\ {x}^{2} = 8.8 \times 0.6 \\ {x}^{2} = 5.28 \\ x = \sqrt{5.28} \\ \boxed{x = 2.3 \: meter}[/tex]
