Which figure has the same area as the parallelogram shown below? A. A triangle with a base of 4 mm and a height of 20 mm B. A tr

Arisa [49]

<h2>Answer: A trapezoid with bases of 6 mm and 14 mm and a height of 8 mm </h2>

The parallelogram in the figure has an area of $80mm^{2}$ , according to the following formula, which works for all rectangles and parallelograms:

$A_{parallelogram}=(b)(h)$ (1)

Where $b$ is the base and $h$ is the height

The<u> area of a triangle</u> is given by the following formula:

$A_{triangle}=\frac{1}{2}(b)(h)$ (2)

So, for option A:

$A_{triangle}=\frac{1}{2}(4mm)(20mm)=40mm^{2} \neq 80mm^{2}$

Now, the <u>area of a trapezoid </u>is:

$A_{trapezoid}=\frac{1}{2}(b_{1}+ b_{2})(h)$ (3)

For option B:

$A_{trapezoid}=\frac{1}{2}(15mm+25mm)(2 mm)=40mm^{2} \neq 80mm^{2}$

For option C:

$A_{trapezoid}=\frac{1}{2}(6mm+14mm)(8 mm)=80mm^{2}$ >>>>This is the correct option!

For option D:

$A_{rectangle}=(30mm)(8mm)=240mm^{2} \neq 80mm^{2}$

<h2>Therefore the correct option is C</h2>

(4,7) y=3x+6 write an equation passing through the point and parallel to the given line

Elis [28]

So, we will be using point-slope form to construct this equation.

Point-slope form's general formula is as follows:

$Y-Y_1=m(X-X_1)$

M is the slope,

Y₁ is the Y-coordinate of the point

X₁ is the X- coordinate of the point.

So, our slope is 3 (since the equation is given in slope-intercept form)

Our Y₁ is 7 and out X₁ is 4

So, now we just plug our numbers into the equation.

$Y-7 = 3(X-4)$

There's your equation.

Hope this helps!

Three out of evry 45 tickets sold in a food bank raffle will win a prize.If Eli bought 15 tickets, how many prizes would he expe

evablogger [386]

i would say you need to divide 45 and 3. then subtract 45 and 15. then with those two numbers you need to put the amount from 45 / 3 on the top and the 15-45 on the bottom. you will get the probability.

i think don't quote me
