1 answer:
Lerok [7]3 years ago
3 0

Answer:

A2 = 120

A3 = 60

A5 = 60

A6 = 120

Step-by-step explanation:

Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.

Angle 1 and 3 are vertical angles, which are always the same measure.

Angle 5 is alternate interior angles with 3, which means it is also 60.

Angle 6 is alternate interior angles with 4, which means it is 120.

15. True or False: Is x = 4 a solution to X + 51 = -9<br> True<br> False
Ivenika [448]

Answer:

False, also the typed version of this problem does not actually use the expression in the accompanying screenshot. That clearly reads as x + 5

Step-by-step explanation:

The problem, assuming x = 4 can be read as 4 + 5. Simple math dictates this would equal nine and as there is no negative to either number nor a negative outside of the lines surrounding the problem itself the solution is simple and leads to a false answer.

A hiker walks 9.4 miles at an angle of 60° south of west. Find the west and south components of the walk. Round your answers to
schepotkina [342]

Answer: The west components of the walk = 4.7 miles

The south components of the walk = 8.1 miles (Approx)

Step-by-step explanation:

Since, the A hiker walks 9.4 miles at an angle of 60° south of west.

Thus,by the below diagram,

The west components of the walk  = 9.4 × cos 60° = 9.4 × 0.5 = 4.7 miles

And, the south components of the walk = 9.4 × sin 60° = 9.4 × √3/2 = 9.4 × 0.866025404 = 8.1406388 ≈ 8.1 miles

Teresa needs
Zina [86]

Answer:

3 5/6 cups of flour

Step-by-step explanation:

You want the total amount so we add both fractions together.

1 1/2 + 2 1/3

I prefer to convert both to an improper fraction and then convert back to a mixed number, so;

1 1/2 = whole number (1) x denominator (2), add numerator (1), = 3, put this over the old denominator (2) = 3/2

2 1/3 = whole number (2) x denominator (3), add numerator (1), = 7, put this over the old denominator (3) = 7/3

Now we add the 2 improper fractions, so we have to convert them both to a common denominator. The LCM of 2 and 3 is 6, so it will be over 6.

3/2 = to get from 2 to 6, you multiply by 3, numerator (3) x 3 = 9, over 6 = 9/6.

7/3 = to get from 3 to 6, you multiply by 2, numerator (7) x 2 = 14, over 6 = 14/6.

9/6 + 14/6 = 23/6

Now we change back into a mixed number, how many times do 6 go into 23? 3 (6x3=18), as 4 would be 24.

So our whole number is 3

What is left goes over our denominator (6): 23 - 18 = 5.

So your answer is 3 5/6 cups of flour.
