Two planes travel at a constant speed. Plane A travels 2,800 miles in 5 hours. Plane B travels 3,885 miles in 7 hours.

1. Which plane is faster?

Answers

Answer 1

Answer: First.

Step-by-step explanation:

Let's find the speed of the first airplane:

2800 ÷ 5 = 560 (miles per hour)

Let's find the speed of the second plane:

3885 ÷ 7 = 555 (miles per hour)

Thus, the first plane flies faster than the second.

Answer 2
The first plane is faster.


The first plane travels at 560 miles per hour. The comparisons are 2 hours apart. Add 560 2 times to 2800 and you get 3,920 which is greater than 3,885, the original number of MPH for the second plane.


Meaning the first plane is faster.

3x+4=9x-8= ????????????

Answers

3x+4=9x-8=2 the answer would be 2
Answer:

Simplifying
3x + 4 = 9x + -8

Reorder the terms:
4 + 3x = 9x + -8

Reorder the terms:
4 + 3x = -8 + 9x

Solving
4 + 3x = -8 + 9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9x' to each side of the equation.
4 + 3x + -9x = -8 + 9x + -9x

Combine like terms: 3x + -9x = -6x
4 + -6x = -8 + 9x + -9x

Combine like terms: 9x + -9x = 0
4 + -6x = -8 + 0
4 + -6x = -8

Add '-4' to each side of the equation.
4 + -4 + -6x = -8 + -4

Combine like terms: 4 + -4 = 0
0 + -6x = -8 + -4
-6x = -8 + -4

Combine like terms: -8 + -4 = -12
-6x = -12

Divide each side by '-6'.
x = 2

Simplifying
x = 2

What is the measure of angle N?

Answers

Answer:  A) 61 degrees

=========================================================

Work Shown:

Apply the law of sines

sin(N)/MO = sin(O)/MN

sin(N)/18 = sin(17)/6

sin(N) = 18*sin(17)/6

sin(N) = 0.87711511416821 ................. which is approximate

N = arcsin(0.87711511416821)

N = 61.296295678111

N = 61 degrees approximately

----------------------

Notes:

Arcsine is the same as inverse sine. Your calculator is likely to have a button labeled [tex]\sin^{-1}[/tex] to indicate inverse sine.There are two solutions to sin(N) = 0.877; however, the other solution for N is larger than 90. This triangle your teacher is showing appears to be an acute triangle where every angle is less than 90 degrees. Technically two triangles are possible with these current given sides and angle.
