Answer~

The answer to this is about 8.424%. You could round it to 8.5% though.

Step-by-step explanation:

apologies if I'm wrong and sorry that I'm late have a nice day if they are both wrong try 8.42

well, from 273 to 250 is 23 bucks, so that's the difference.

we know 273 is the original price, or namely the 100%, so what's 23 bucks off of it in percentage?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 273&100\\ 23&x \end{array}\implies \cfrac{273}{23}=\cfrac{100}{x}\implies \implies 273x=2300 \\\\\\ x=\cfrac{2300}{273}\implies x\approx 8.42$

application. Line segment AB is a translation of line segment CD 6 units down. Drag line segment CD and try to move it onto line

Svetllana [295]

Solid transformation is a method that requires a change in the length of sides of a given shape or a change in its orientation. Thus the required answers are:

i. Yes, line segment AB is the same as line segment CD.

ii. This implies that translation does not affect the length of a given line, but there is a change in its location.

Solid transformation is a method that requires a change in the length of sides of a given shape or a change in its orientation. Some types of transformation are reflection, translation, dilation, and rotation.

Dilation is a method that requires either increasing or decreasing the size of a given shape.
Translation is a process that involves moving every point on the shape in the same direction, and the same unit.
Reflection is a method that requires flipping a given shape over a given reference point or line.
Rotation requires turning a given shape at an angle about a given reference point.

Thus in the given question, translation would not affect the length of line segment AB, thus line segment AB and CD are the same. Also, A translated line segment would have the same length as its object, but at another location.

Your chemistry textbook has 936 pages and weighs 4.2 pounds. your calculus textbook has 1368 pages and weighs 6.0 pounds. these

Zarrin [17]

Let the number of chemistry books be x and the number of calculus books be y
total number of books in each case is:
x+y=24
x=24-y.....i

Weight of each case:
2707.2/20
=135.36
thus
4.2x+6.0y=135.36..ii substituting i in ii
4.2(24-y)+6y=135.36
100.8-4.2y+6y=135.36
hence
1.8y=34.56
y=19.2
hence
x=24-19.2
x=4.8
thus the number of chemistry books was 4.8*20=96 number of calculus was
19.2*20
=384 books
