4sinθ + 3√3 = √3
First subtract 3√3 from both sides:
4sinθ = -2√3
Now, divide by 4:
sinθ = (-2√3)/4
sinθ = -√3/2
Using the unit circle we know that sin of -√3/2 is 240° or 4/3π and 300° or 5/3π

a jet takes 5 3/4 hours to fly 2,475 mi from new york city to los angeles. about how many hours will a jet flying at the same average rate take to fly 5,452 mi from los angeles to tokyo? Please explain using ratios.
Answers
Time = 5³/₄ hours
Distance = 2475 miles
Speed = Distance ÷ Time
= 2475 ÷ 5³/₄
= ⁹⁹⁰⁰/₂₃ = 430.43 miles/hour
Distance LA - Tokyo = 5452
Speed = 430.43 miles/hour
Time = Distance ÷ Speed
= 5452 ÷ 430.43
= 12.7 hours
Using ratios:
2475 miles ⇒ 5³/₄ hours
5452 miles ⇒ x hours
Find the multiplier ⇒ 5452 ÷ 2475 = 2.203
Then multiply 2.203 by 5³/₄ to get 12.7 hours

Si S es el 150% de T, qué tanto por ciento de T es (S + T)?
Answers
If S is 150% of T, then to find what percentage (S + T) is of T, we calculate (S + T) / T * 100. By substituting S = 1.5T into the equation, we determine that (S + T) equals 250% of T.
Explanation:If S is the 150% of T, this implies that S is 1.5 times T (since 150% can be expressed as 1.5 in decimal form). To express S as a percentage of T, we can set up the equation S = 1.5T.
Now, we are asked to find what percentage of T is (S + T). To find this, we simply add S and T together: S + T = 1.5T + T = 2.5T. Now, to express this sum as a percentage of T, we divide the sum by T and then multiply by 100.
So, ((S + T) / T) * 100 = (2.5T / T) * 100 = 2.5 * 100 = 250%. Therefore, (S + T) is 250% of T.
To find the percentage that (S + T) is of T, we first need to find the value of S and T. The given information states that S is 150% of T. This means that S = 1.5T. To find (S + T), we substitute the value of S in terms of T: (1.5T + T) = 2.5T.
Now, to find the percentage that (S + T) is of T, we divide (S + T) by T and multiply by 100: ((2.5T / T) imes 100) = 250%.
Therefore, (S + T) is 250% of T.
The perimeter of a geometric figure is the sum of the lengths of its sides. If the perimeter of the pentagon to the right (five-sided figure) is 96 meters, find the length of each side. 2 of the sides= 2.5x
Answers
The length of each side of the pentagon is 19.2 meters.
Explanation:To find the length of each side of the pentagon, we need to divide the perimeter of the pentagon by 5, since a pentagon has 5 sides. If the perimeter is 96 meters, each side would have a length of 96/5 = 19.2 meters.

You have to convert 1.56x10^4 into a normal number so that is : 15600
Then you convert 15600 into hours and seconds:
15600/60=260
260/60=4.3recurring
4 hours and 3recurring seconds
So that means Miguel ran the race in a shorter amount of time.

If there are a number of different sounds being produced simultaneously, the resulting intensity is the sum of the individual intensities. How many decibels louder is the sound of quintuplets crying than the sound of one baby crying?
Answers
Δ L = level difference.
n = number of equal loud sound sources.
n = 5
10 × log10 5 = +6.9897 dB compared to the case that only one source is available.
The sound of quintuplets crying is 7 dB louder than the sound of one baby crying because a factor of five in intensity corresponds to a 7 dB increase in sound intensity level.
Explanation:The question asks how many decibels louder the sound of quintuplets crying would be compared to the sound of one baby crying. To calculate this, we need to understand that intercity levels in decibels (dB) are measured logarithmically. This means that for every ten-fold increase in intensity, the sound level goes up by 10 dB. We also know that a factor of five in intensity corresponds to an increase of 7 dB.
If one baby crying produces a certain sound intensity, then five babies (quintuplets) crying simultaneously would increase the intensity by a factor of five. Hence, the sound of quintuplets crying would be 7 dB louder than the sound of one baby crying, based on the given references.
If a and b are any two real numbers, explain how you calculate the difference a - b. Be sure to include the following in your explanation.

(B) how you can use a number line to help with the calculation

Answers
- The number line allows us to interpret subtraction (or addition of a negative) geometrically; we can view it as a movement to the left on the number line with a distance equal to the number being subtracted.
- Lastly, the value of any expression a - b (where a and b are real numbers) is determined by the relative sizes of the numbers. If a > b, then a - b > 0 (a positive result). If b > a, then a - b < 0 (a negative result.

Josh walked a total of 5 miles today. First he walked 1 mile from his house to the park then he walked laps around the 3/4 mile loop trail at the park. Finally he walked back home. Howany laps did Josh walk around the trail?
Answers
Josh walked 4 laps around the trail.
To find out how many laps Josh walked around the trail, we first need to calculate the distance he walked from his house to the park and back, and then subtract that from the total distance.
Distance from home to park: Josh walked 1 mile from his house to the park.
Distance from park to home: He also walked 1 mile back home.
Now, let's calculate the total distance Josh walked around the trail:
Total distance walked = Total distance - (Distance from home to park + Distance from park to home)
Total distance walked = 5 miles - (1 mile + 1 mile)
= 5 miles - 2 miles
= 3 miles
Now, we know that Josh walked laps around a 3/4 mile loop trail, and he walked a total of 3 miles. To find out how many laps he walked, we divide the total distance by the distance of each lap:
Number of laps = Total distance / Distance per lap
= 3 miles / (3/4 mile)
= 3 miles * (4/3)
= 4 laps
So, Josh walked 4 laps around the trail.
