Area of a trapizium is 84m².its pararrell sides are 12m and 9m. find its hiegh

Maksim231197 [3]

<em>Answer:</em>

<em>8m</em>

<em>Step-by-step explanation:</em>

<em>We can convert the trapezium into a rectangle to make finding the area easier.</em>

<em>Say that the top side is 9m, and that the bottom side is 12m.</em>

<em>12 - 9 = 3</em>

<em>3/2* = 1.5</em>

<em>*Note that we are dividing by two to get the "overhang" of the bottom side.</em>

<em>Now that we have our overhang, we can find the length of the "t-rect"**.</em>

<em>**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.</em>

<em>12 - 1.5 = 10.5</em>

<em>9 + 1.5 = 10.5</em>

<em>The length of the t-rect is 10.5.</em>

<em>84/10.5 = 8</em>

<em>The height of the t-rect is 8m.</em>

<em>Since the height of the original trapezium is equal to the height of the t-rect***, </em>

<em>***Since we have only adjusted the length</em>

<em>this also means that 8m would also be the height of the original trapezium.</em>

<em>Now, there is a second way of doing this.</em>

<em>Find the median of 12 and 9.</em>

<em>9, 10, 11, 12</em>

<em>10, 11</em>

<em>The median is 10.5.</em>

<em>84/10.5 = 8</em>

<em>You get the same answer. These methods could be used as a solve-then-check method to another problem like these.</em>

<em>Hope this helps. Have a nice day.</em>

The area of a rectangle is 1,357 square feet. The length is 59 feet. What is the width?

dangina [55]

Answer:

w = 23

Step-by-step explanation:

a = l × w

The area and length are given, so you can substitute them in.

1357 = 59 × w

Solve for w:

w = $\frac{1357}{59}$

w = 23

writing an equation of a line given its slope and y-intercept. write an equation in slope-intercept form for the line with slope

Gre4nikov [31]

Answer:

y = -5(x-1)

Step-by-step explanation:

A y-intercept of 1 means that the point (0,1) falls on the line.

Slope-intercept form is $y-y_{1} =m(x-x_{1} )$ where m is the slope...

Therefore, the slope-intercept equation is y-1=-5(x-0) or y-1=-5x

Please help it’s the last question

Mrac [35]

Answer:

$y=$ $-\frac{5}{6}x - 1$ is the answer

Step-by-step explanation:

Equation of the line: y = 6/5x + 1

= 5y = 6x + 5

= 6x - 5y + 5

Equation of the perpendicular line: bx - ay + k = 0

= -5x -6y + k = 0

Equation passes through (6,-6),

-5(6) -6(-6) + k = 0

-30 + 36 + k = 0

6 + k = 0

k = -6

Substituting,

-5x -6y + k = 0

-5x -6y -6 = 0

-6y = 5x + 6

$y=$ $-\frac{5}{6}x - 1$ (Slope-Intercept form)
