Answer:

A;H;D;G

Step-by-step explanation:

Altitude is a line from a vertex that intersects a side at a 90 degree angle. DE is the only altitude shown

Perpendicular bisectors divide a side into 2 congruent pieces, at a 90 degree angle. GB is the only perpendicular bisector shown.

An angle bisector is a line that divides an angle into 2 angles with the same measure. CF is the only angle bisector shown.

A median is a line that goes through a vertex and divides a side into 2 congruent lengths. AB is the only such example.

At the movie theatre, child admission is $5.40 and adult admission is $8.70 . on friday, 159 tickets were sold for a total sales
blondinia [14]
Alright this is gonna be a long one

Lets called child tickets x and adult tickets y 

so x + y should be equal to 159 since they said that the total sum of the tickets is 159 
so thats your first equation : x + y = 159

next form an equation using the prices, 
5.40x + 8.70y = 1079.70

now that you have your two equations, just substitute the first into the second (you could either substitute for x or y by saying x = 159-y or that y=159-x)

Hope this helps.

Claire said that 10/15 of her CDs are country music. Which statement could be true based upon this relationship?
never [62]

Answer:

C. Claire has 10 country CDs and 5 Jazz CDs

Step-by-step explanation:

\dfrac{10}{15} means that 10 out of 15. So we can assume that in total she has 15 CDs and 10 of them are Country and the other is Jazz.

This would rule out choice D.

If we reduce this fraction then we would have:

\dfrac{10}{15} = \dfrac{2}{3}

This means that two-thirds of her CDs are country music. So this would rule out A and B choices.

Now C is correct because 10 country plus 5 Jazz is equal to 15 CDs. So we have the correct total.

The answer is C.
