<span>idk if this exactly correct but i tried

1 Find and add the lengths of all the polygon's sides
2.Multiply the lengths of equal sides by the number of equal sides.
3 Multiply a regular polygon's side length by the number of sides.
4 Alternatively, use the area and apothegm of the polygon.

Nico wants to use a horizontal number line to compare 1 3/4

e-lub [12.9K]

Answer:

1 3/4 is greater than 1.5.

Step-by-step explanation:

1. To make a line that measures 1 3/4, make 2 regular lines.

2. Divide one of the lines into 4 equal sections and erase the one section and leaving you with 1 3/4.

To make the 1.5:

1. Make a line and make another line but that is half of the length of the previous line.

Answer:

Look at your answers for the last question in all four sets. Locate these four elements on the periodic table. Enter the name of the group that all four elements belong to. Watch your spelling! [Hint: If all four answers for the last question are not in the same group on the periodic table, redo your sets or contact your instructor.]

A screen reader friendly version of the periodic table (opens in a new window) is available, as well as a printable, black and white version (opens in a new window).

A pet store donated a percent of every sale to hospitals. The total sales were $8,750 so the store

Salsk061 [2.6K]

Divide the amount donated by total sales then multiply by 100.

350 / 8750 = 0.04

0.04 x 100 = 4%

What is the perimeter of the trapezoid with vertices Q(8, 8), R(14, 16), S(20, 16), and T(22, 8)? Round to the nearest hundredth

EleoNora [17]

Check the picture below.

so... you can pretty much see how long RS and QT are, you can just count the units off the grid.

now, let's find QR's length

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&Q&(~ 8 &,& 8~) 
% (c,d)
&R&(~ 14 &,& 16~)
\end{array}~~ 
% distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
QR=\sqrt{(14-8)^2+(16-8)^2}\implies QR=\sqrt{6^2+8^2}
\\\\\\
QR=\sqrt{36+64}\implies QR=\sqrt{100}\implies QR=10$

and let's also find the length for ST

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&S&(~ 20 &,& 16~) 
% (c,d)
&T&(~ 22 &,& 8~)
\end{array}~ 
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
ST=\sqrt{(22-20)^2+(8-16)^2}\implies ST=\sqrt{2^2+(-8)^2}
\\\\\\
ST=\sqrt{4+64}\implies ST=\sqrt{68}\implies ST=\sqrt{4\cdot 17}
\\\\\\
ST=\sqrt{2^2\cdot 17}\implies ST=2\sqrt{17}$

so, add the lengths of all sides, and that's the perimeter of the trapezoid.
