Since we know sin^2 θ = (sin θ)^2
In our problem,
sinθ = 2/sqrt(3)
Let's plug this value into our expression above.
(2/sqrt(3))^2
Let's square both terms individually.
2^2 = 4
(sqrt(3))^2 = 3
The final answer = 4/3

Single-tickets sell for $20 each and a couple-tickets for $35 each. A total of 160 tickets are
sold, and the total value of the ticket is $4100. How many of each kind of ticket were sold?
Answers
Answer:
100 of the 20$ tickets, and 60 of the 35$ tickets
Step-by-step explanation:
20*x + 35*y = 4100
x + y = 160
That means x = 160 - y, put this into the first equation
20(160 - y) + 35y = 4100
3200 - 20y + 35y = 4100
15y + 3200 = 4100
15y = 900
y = 60
Put y = 60 into the second equation and
x + 60 = 160
x = 100
y = 60, x = 100
Double check that this works for both equations to make sure its right
20 * 100 + 35 * 60= 4100
2000 + 2100 = 4100 /Correct
100 + 60 = 160 /Correct

Line p passes through (8,-6) and is perpendicular to the line 2x+y=-7.
The slope of line p is?
A- -2
B- -1/2
C- 1/2
D- 2
(How do I solve to find slope)
Answers
Answer:
C) 1/2
Step-by-step explanation:
The slope of a perpendicular line is the negative inverse.
First, convert the given line to slope-intercept form.
2x + y = -7
y = -2x − 7
The slope of this line is -2. So the slope of the perpendicular line is:
m = -1 / (-2)
m = 1/2
The bill from your plumber was $134. The cost for labor was $32 per hour. The cost for materials
was $46. How many hours did the plumber work.
Answers
Answer:
2.75 hours, or 2 hours and 45 minutes
Step-by-step explanation:
Subtract the cost of materials from the bill, 134-46=88.
Then, for every hour, he charges 32, so divide the difference by 32, 88/32.

Angle XYZ = 2X° and angle PQR = (8X -20)°. If angle XYZ and angle PQR are supplementary, find the measure of each angle. Angle PQR = ?
Answers
Answer:
[tex]PQR = 140[/tex]
Step-by-step explanation:
Given
[tex]XYZ = 2X[/tex]
[tex]PQR = 8X - 20[/tex]
Required
Find PQR
Since both angles are supplementary, we have:
[tex]XYZ + PQR = 180[/tex]
This gives:
[tex]2X + 8X - 20 = 180[/tex]
[tex]10X - 20 = 180[/tex]
Collect Like Terms
[tex]10X = 20 + 180[/tex]
[tex]10X = 200[/tex]
Divide through by 10
[tex]X = 20[/tex]
Substitute 20 for X in [tex]PQR = 8X - 20[/tex]
[tex]PQR = 8 * 20 -20[/tex]
[tex]PQR = 140[/tex]

Jaiden's pen pal from Mexico said that he lives 3.3 kilometers from school. Jaiden knows
that 1 kilometer is approximately 0.62 miles. Which is the closest distance (in miles) that
Jaiden's pen pal lives from school?
Answers
Answer:
2 miles
Step-by-step explanation:
3.3 kilometers to miles is 2.0505. I'm not sure if this question want you to round, but if it does, the answer would be 2 miles.
To get your approximate answer, multiply 3.3 (kilometers) by 0.62 (miles).
You get 2.046 if you multiply it by 0.62 like the question says to do.
If the statement is rewritten as a conditional statement in if-then form, which best describes the hypothesis?

If the statement is rewritten as a conditional statement in if-then form.
As we know,
From the definition of the hypothesis.
The null and alternative hypotheses are two generalizations about a population that are strictly contradictory
The hypothesis is best described as two lines intersecting at a point if the original sentence is restated as a conditional statement in the if-then format.
Thus, the statement "Two lines intersect at a point" is the correct option (B) that would be the best choice.

Which statement best describes how Charlemagne expanded his territory in Europe? He led the Catholic Church as the Holy Roman emperor. He became king of the Franks and then conquered other lands. He created schools in the kingdom and then became emperor of Saxony. He created new laws that allowed him to become king of the Lombards and Saxons.
Answers
Answer:
He became king of the Franks and then conquered other lands.
Step-by-step explanation:
Charlemagne became king of the Franks after the death of his father, Pepin the Short.
He inherited a sizeable portion of land that included what is now France, the Low Countries, and parts of Germany.
Charlemange launched several military campaigns throughout his long reign (he ruled for 46 years), and was highly successful in most of them. He conquered Northern and Central Italy, what is now Switzerland and Austria, and the majority of modern day Germany.
He was crowned Holy Roman Emperor in the year 800 by Pope Leo III. In exchange for this, Charlemange ceded a section of Central Italy to the Pople: the Papal States, which would be under direct control of the Roman Catholic Church until the Napoleonic Era.

A gumball machine contains 100 gumballs of 5 different colors: 36 red, 15 blue, 24 orange, 12 green, and the rest are white. The machine dispenser randomly selects one gumball. What is the probability that the gumball dispensed is white?
Answers
Answer:
13
Brainliest?
Step-by-step explanation:
The probability that the gumball dispensed white would be 87%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
It can be express the probability in either fraction form or in percentage. The numerator would be number of all possibilities, while the denominator is the number of all events.
Here the numerator is the number of white gumballs, while the denominator is the number of all gumballs available.
To solve for the number of white gumballs, subtract all the other balls to the total.
Number of white balls = 100 - 36 red - 15 blue - 24 orange - 12 green
Number of white balls = 13
Thus,
Probability of white ball = 87/100= 87%

PLZ HELP, GIVING BRAINLIEST!! A swimmer dives straight into the ocean.

How long does it take the swimmer to reach the lowest depth? a. 9 feet, 16 seconds b. 16 feet, 3 seconds c. 3 feet, 16 seconds d. 16 feet, 9 seconds
Answers
The time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a swimmer dives straight into the ocean. His depth, d, in meters after t seconds, can be modeled using the equation d = (t - 3)² - 16.
The time will be calculated as below;-
d = ( t - 3 )² - 16.
16 = ( t - 3 )² - 16
32 = ( t - 3 )²
√32 = t - 3
5.67 = t - 3
t = 5.67 + 3 = 8.67 ≅ 9 seconds
Therefore, the time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.
