In a tea shop there are 30 different types of green tea. how many ways can i
select 15 different types of green tea to take home?

155117520

Step-by-step explanation:

The number of combinations of r things selected from a group of n things at a time is given by :-

Given : The total number of different types of green tea = 30

The number of different types of green tea you wish to select =  15

Then , the number of combinations of selecting 15 different types of green tea from 30 at a time is given by :-

Hence, there are 15511752 ways you can select 15 different types of green tea to take home.

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
