Find the area of the trapezoid

Alexandra [31]

Answer:

$\sf area \ of \ trapezoid \ =375 \ mm^2$

Explanation:

$\sf area \ of \ trapezoid \ = \dfrac{1}{2} * ( base \ 1 + base \ 2 ) * height$

using the formula:

$\sf area \ of \ trapezoid \ = \dfrac{1}{2} * ( 14+ 36 ) * 15$

$\sf area \ of \ trapezoid \ = \dfrac{1}{2} * ( 50 ) * 15$

$\sf area \ of \ trapezoid \ =25 * 15$

$\sf area \ of \ trapezoid \ =375 \ mm^2$

Explain what defines direct variation. Then, check which of the following tables include directly proportional quantities x and

just olya [345]

Direct variation in mathematics is when two numbers are written in an equation where one of the numbers multiplied by a constant term to equal the other.

In the table in the equation, we see direct variation.

X Y
1 7
2 14
3 21
4 28

We can find the constant of the variation by dividing y by x. This constant should remain the same for all terms of x in the table with their corresponding y values.

y/x
7/1=7
14/2=7
21/3=7
28/4=7

As we can see, the values in the table all share a direct variation between x and y with the value 7.

This can be expressed in an equation: y = 7x.
