An airplane leaves an airport and flies due west 170 miles and then 240 miles in the direction S 69.50°W. How far is the plane from the airport (round to the nearest mile)?.

Answers

We will use the Cosine Law:
c² = a² + b² - 2 a b cos C
∠ C = 90° + 69.50° = 159.50°
c² = 170² + 240² - 2 · 170 · 240 · cos ( 159.50° )
c² = 28,900 + 57,600 - 81,600 · ( -0.9366722 )
c² = 28,900 + 57,600 + 76,432.45
c = √ 162,932.45
c = 403.64  ≈ 404 miles
Answer:
The plane is 404 miles away from the airport. 

Answer:

C=403.6489

Step-by-step explanation:

A= 170, B= 240 angle C= 69.5+90=159.5

C= the distance from the plane to the airport.

Bailey and Jade both play basketball. The table and graph show the total number of games that each of their teams won over six weeks. A coordinate plane labeled Jade's Team. The x-axis is labeled Weeks and the y-axis is labeled Wins. Points plotted are (1, 0), (2, 1), (3, 3), (4, 5), (5, 6), and (6, 7). Bailey’s Team Number of weeks Wins 1 2 2 2 3 3 4 4 5 4 6 6 After which week had the two teams won the same number of games?

Answers

Answer:

week 3

Step-by-step explanation:

week 3 is correct, because both of their teams have 3 wins for week 3 as stated on Bailey's table and plotted on Jade's graph.

Write the equivalent fraction of 3 /5 having denominator 35

Answers

Answer:

(21)/(35)

Step-by-step explanation:

to obtain the equivalent fraction to (3)/(5) with a denominator of 35

note that 5 × 7 = 35

then multiplying the numerator and denominator by 7 will give the required fraction.

(3)/(5) = (3(7))/(5(7)) = (21)/(35)

Final answer:

To find the equivalent fraction of 3/5 with a denominator of 35. result is 21/35.

Explanation:

To find the equivalent fraction of 3/5 with a denominator of 35, you need to multiply both the numerator and denominator by the same number so that the denominator becomes 35. In this case, you need to multiply both 3 and 5 by 7.

So, 3/5 is equivalent to (3 * 7) / (5 * 7) = 21/35.
