Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

\frac{AB}{DE} = \frac{BC}{EF} , substitute values

\frac{AB}{17.64} = \frac{6.3}{13.23} ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

\frac{DF}{AC} = \frac{EF}{BC}, substitute values

\frac{DF}{4.1} = \frac{13.23}{6.3} ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61

For each ordered pair in the table, how does the second number compare to the first number... can yall tell me I need to turn it
spayn [35]

Answer:

The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.

9.92749, √101, 0.99853, 10π greatest to least
Fudgin [204]

Using a calculator, determine the value of √101 to four or five decimal places.  Do the same with 10π.  We get { 9.92749, 10.0500, 0.99853, 31.4159}.

Arranging these in descending order, we get {10π, √101, 9.92749, 0.99853}.

Steam and leaf plot help!!!! picture down below
Diano4ka-milaya [45]
I would say that the correct answer is C because if you look up on the chart thing, it tells you how you would see the graph. For example, when you have:

1| 03145
2| 4 6 3 7

Which one has the most value to it? It would be the 2| 4 6 3 7, because when you put them together, it makes 24, 26, 23, 27. Hope this helps.
