Answer:

Area = 38.1 ft² (nearest tenth)

Step-by-step explanation:

Use sine rule for area of a triangle:

Area = (1/2)ab sin(C)

        = (1/2)bc sin(A)

        = (1/2) x 11 x 8 x sin(60)

        = 22√3

        = 38.1 ft² (nearest tenth)

dalvyx [7]

18 workers

Answer:

4 workers can assemble 12 computers in 9 hours.

Since the number of hours is directly proportional to the number of computers:

4⋅12=48 computers could be assembled by 4 workers in 4⋅9=36 hours.

Since the number of hours is inversely proportional to the number of workers:

48 computers could be assembled by 92⋅4=18 workers in 29⋅36=8 hours.

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 6) and (2, 0). a. Negative one-third c. 3 b.
statuscvo [17]

The slope of the line that passes through between (0, -6) and (2, 0) is: C. 3.

<h3>What is the Slope of a Line?</h3>

The slope of a line can be defined as the measure of the ratio of the vertical distance to the horizontal distance that exists between two points on a coordinate plane.

<h3>How to Find the Slope of a Line?</h3>

If we are given two points on a line, (x1, y1) and (x2, y2), the slope (m) is the rise/run = change in y / change in x = (y2 - y1)/(x2 - x1).

Given the following coordinates of two points as follows, (0, -6) and (2, 0), let:

(0, -6) = (x1, y1)

(2, 0) = (x2, y2)

Plug in the values into the slope formula to find the slope:

Slope (m) = (0 - (-6)) / (2 - 0)

Slope (m) = (0 + 6) / (2 - 0) [minus multiplied by minus is plus]

Slope (m) = (6) / (2)

Slope (m) = 3

Thus, the slope of the line that passes through between (0, negative 6) and (2, 0) is calculated as: C. 3.
