74 3/5 + 19 2/3 = Please Explain
Answers
So 19
= 373/5 + 59/3
= ((373 × 3) + (59 × 5)) / (5 × 3)
= (1119 + 295) / 15
= 1414/15
= 1414/15
= 94 4/15
74+19= 93
for 3/5+2/3 we need a common denominator which in this case would be 15 (the product of the two already existing denominators)
3x3=9 (the 3s are first numerator and the second denominator) so the first fraction is 9/15
5x2=10 (the first denominator and the second numerator) so the second fraction would be 10/15
9+10=19 (the numerators in both fractions) so it's 19/15 which we convert to a mixed numeral which is 1 4/15
93+1 4/15=94 4/15
hope this helps :)

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.

Answer:
2
Step-by-step explanation:
Since the 12 + 6 are parenthesis, we do these first
12 + 6 = 18
Then will solve the rest, 20 - 18
20 - 18 = 2, therefore leaving us with the answer of 2

So, about 18 inches.
Or 17.93in with significant digits.
To break it down, you can set up your information as a fraction (which I did for the first fraction.) Then you want your units to cancel out, so I put the 7.489 minutes on the top of the next fraction and multiplied them. The min canceled out and left me with in, so I know I had the correct answer.
