loris [4]

Answer:

$(B) \dfrac12H (B+D)$

Step-by-step explanation:

$\text{Area of a trapezoid }= \dfrac12 ($Sum of the parallel sides) \times $Height\\Parallel Sides = B and D\\Height =H\\Therefore:\\\text{Area of the trapezoid }= \dfrac12 (B+D) H$

The correct option is B.

What is the equation of this line in slope-intercept form?

12345 [234]

Answer:

y = -2x + 5

Step-by-step explanation:

Slope-intercept form: y = mx + b

The slope of the line, m, is -2 because the line shows a negative trend and moves right 1 unit every time a point moves down 2 units.

The y-intercept, b, is 5 because the line crosses that number once on the y-axis.

Explain the relationship between the number of painters and sculptors enrolled in the art schools?

nasty-shy [4]

The relationship between the number of painters and sculptors enrolled in the art school can be considered a direct variation.

<h3>Direct variation</h3>

A direct variation as implied above means, the linear relationship between the number of painters and sculptors enrolled in the art school are directly proportional.

In essence, as the number of sculptors in the art schools increase, the number of painters increases too. This is because, more painters are needed to paint increasing work volume of the sculptors.
