Answer:

Angles IJG and KJL are vertical angles

Step-by-step explanation:

Vertical angles are formed when two lines intersect. It's a terrible name for them, because the name has nothing to do with the common word "vertica" (up-and-down).

The attached image shows an example of a pair of vertical angles. Another pair is angles AED and CEB.

saveliy_v [14]

Answer:

19.2 centimeters

Step-by-step explanation:

Tia cut a 4 meter and 8 centimeter wire, converting this measure to centimeters

$4m + 8 cm = 400cm + 8cm =408 cm$

and she cut it into 10 equal pieces, thus each piece measures:

$\frac{408cm}{10}=40.8cm$ .

Martha has a wire of 540 centimeter wich she cutted into 9 equal pieces, so each piece measures:

$\frac{540cm}{9} =60cm$

The difference between the two wires is:

$60cm - 40.8cm=19.2cm$

Jonathan can throw a baseball 10 1/3 yards. His brother Joey can throw a baseball 13 1/2 yards. How much father can Joey throw t

butalik [34]

let's firstly convert the mixed fractions to improper fractions, and then subtract.

$\bf \stackrel{mixed}{10\frac{1}{3}}\implies \cfrac{10\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{31}{3}}~\hfill \stackrel{mixed}{13\frac{1}{2}}\implies \cfrac{13\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{27}{2}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{27}{2}-\cfrac{31}{3}\implies \stackrel{\textit{using the LCD of 6}}{\cfrac{(3)27~~-~~(2)31}{6}}\implies \cfrac{81~~-~~62}{6}\implies \cfrac{19}{6}\implies 3\frac{1}{6}$

a dart board has 10 equally sized slices numbered from 1-10. some are grey and some are white. the slices numbered 1,2,3,4,5,6,8

mr_godi [17]

Answer:

We have 10 sections, we can assume that the probability of hitting each of one of them is the same.

we have 9 grey slices and 1 white slice, then the probability of landing in a grey slice is equal to the number of grey slices divided by the total number of slices:

P(X) = 9/10 = 0.90

The probability of not landing in a grey slice is equal to the probability of landing in the white slice, this is:

P(not X) = 1/10 = 0.10

Also, when you have only two events, you can calculate this as:

P(not X) = 1 - P(X) = 1 - 0.90 = 0.10
