There are 60 minutes in an hour. And 24 hours in a day. So logically if you have common math sense. Then you would multiply them together and get the total number of minutes in each day. Then you would divide 8640 (because it was minutes) by the number of minutes in the day and you would get you number which would be 6. Again I literally think that if you had common math sense you would just lowkey understand that. With all sarcasm involved

$8640min (\frac{1 hr}{60 min}) (\frac{1 day}{24 hr}) = 6 days$

1. answer the three questions below about the quadrilateral:

mars1129 [50]

Before we begin, note that we need to use the distanse formula for everything to reach our conclusion. With that being said, here we go:

$\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = d$

Using the ordered pairs $\displaystyle [3, -3]$ and $\displaystyle [4, -2]$ for instanse:

$\displaystyle \sqrt{[-3 + 4]^2 + [3 - 2]^2} = \sqrt{1^2 + 1^2} = \sqrt{2}$

Now, sinse the distanse between $\displaystyle [3, -3]$ and $\displaystyle [4, -2]$ is $\displaystyle \sqrt{2}$ units, then the distanse between $\displaystyle [1, 1]$ and $\displaystyle [0, 0]$ ALSO has to be $\displaystyle \sqrt{2}$ units. By definition, lettre c has already been answered for you because sinse it is a rectangle, if the two short sides are congruent, then the two long sides ALSO have to be congruent, but just in case you want to be sure [you do not trust your instincts], just simply re-use the distanse formula.

Using the ordered pairs $\displaystyle [1, 1]$ and $\displaystyle [4, -2]$ for instanse:

$\displaystyle \sqrt{[-1 + 4]^2 + [-1 - 2]^2} = \sqrt{3^2 + [-3]^2} = \sqrt{9 + 9} = \sqrt{18} = 3\sqrt{2}$

So there you have it. The length of both of the long sides is $\displaystyle 3\sqrt{2}$ units.

Now that we cleared all of that up, we can now find the perimetre and area of this rectangle:

$\displaystyle 2w + 2l = P$

$\displaystyle 2[\sqrt{2}] + 2[3\sqrt{2}] = 2\sqrt{2} + 6\sqrt{2} = 8\sqrt{2}$

The perimetre of this rectangle is $\displaystyle 8\sqrt{2}$ units.

$\displaystyle wl = A$

$\displaystyle [\sqrt{2}][3\sqrt{2}] = [3][2] = 6$

The area of this rectangle is $\displaystyle 6$ squared units.

You have now found what you were looking for.

** All rectangles are parallelograms because they both have two pairs of parallel and congruent sides, while vice versa is falce because a parallelogram does not have four congruent right angles, so it is safe to say that this is both a rectangle AND parallelogram, sinse the picture displayed is a rectangle.

I am joyous to assist you at any time. ☺️
