Answer:

x ≈ 13.5

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan34° = \frac{opposite}{adjacent} = \frac{x}{20} ( multiply both sides by 20 )

20 × tan34° = x , then

x ≈ 13.5 ( to the nearest tenth )

Which equation represents a line which is parallel to the line y=1/5x -1
masha68 [24]

9514 1404 393

Answer:

  (c) 5y - x = -20

Step-by-step explanation:

When the x- and y-terms are on the same side of the equation, the slope of the line will be ...

  m = -(coefficient of x)/(coefficient of y)

So, the slopes of the offered choices are ...

  a) -5/1 = -5

  b) -1/5

 c) -(-1)/5 = 1/5 . . . . . parallel to given line

  d) -5/-1 = 5

The lines will be parallel when their slopes are the same. The slope of the given line is the coefficient of x, 1/5. Choice C has the same slope.

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday. If the coach's friend jogs twice as far as t
Bond [772]

Answer:

Coach's friend jog <u>8.6 miles</u>.

Step-by-step explanation:

Given:

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday.

If the coach's friend jogs twice as far as the coach.

Now, to find the miles the coach's friend jog.

<em>Coach jogs on Monday = 1.8 miles.</em>

<em>Coach jogs on Tuesday = 1.3 miles.</em>

<em>Coach jogs on Wednesday = 1.2 miles.</em>

Total miles coach jog <em>= </em>1.8+1.3+1.2=4.3\ miles.<em />

As, coach's friend jogs twice as coach.

So, to get the miles coach's friend jogs multiply total miles coach jog by 2 we get:

Total\ miles\ coach\ jog\times 2

 4.3\times 2\\\\=8.6\ miles.

Therefore, coach's friend jog 8.6 miles.
