Answer:

None of the above ? （the equation should be y=12）

Step-by-step explanation:

the line parallel to line y=40-1=39 means it's a horizontal line. Which means it's y coordinate is also a constant. Since it pass through （2,12）,it means the constant of y is 12.

Answer:

(i) x° = 70°, y° = 20°

(ii) ∠BAC ≈ 50.2°

(iii) 120

(iv) 300

Step-by-step explanation:

(i) Angle x° is congruent with the one marked 70°, as they are "alternate interior angles" with respect to the parallel north-south lines and transversal AB.

x = 70

The angle marked y° is the supplement to the one marked 160°.

y = 20

(ii) The triangle interior angle at B is x° +y° = 70° +20° = 90°, so triangle ABC is a right triangle. With respect to angle BAC, side BA is adjacent, and side BC is opposite. Then ...

tan(∠BAC) = BC/BA = 120/100 = 1.2

∠BAC = arctan(1.2) ≈ 50.2°

(iii) The bearing of C from A is the sum of the bearing of B from A and angle BAC.

bearing of C = 70° +50.2° = 120.2°

The three-digit bearing of C from A is 120.

(iv) The bearing of A from C is 180 added to the bearing of C from A:

120 +180 = 300

The three-digit bearing of A from C is 300.

Are the fractions 1/5 , 5/5 , and 5/1 equivalent?Explain.

NeX [460]

Answer:
They are not equal

Explanation:
Let's take a look at each one of them separately:
 $\frac{1}{5}$ : This fraction is in the simplest form. It is equivalent to 0.2
The fraction is formed by dividing one part over five

 $\frac{5}{5}$ : This fraction is not in the simplest form. We can divide 5 by 5 and the answer would be 1. Therefore, $\frac{5}{5}$ is equivalent to 1

 $\frac{5}{1}$ : This fraction is not in the simplest form. We can divide 5 by 1 and the answer would be 5. Therefore, $\frac{5}{1}$ is equivalent to 5.

Based on the above, we can cnfirm that 0.2 , 1 and 5 are not equivalent.
Therefore, the given fractions are not equivalent

Hope this helps :)
