11a.
12a-1a=11a is same thing as 12a-a
A=30^2+ 2 x 30 x 26
A= 900 + 1560
A= 2460
so the surface area is 2460
v=1/3 x 30^2 x 26
v=1/3 x 900 x 26
v= 300 x 26
v=7800
so the volume is 7800
and the way the order of operations helped you is that you had to remember to always do the exponents before any of the other multiplication
Answer: Option 'b' is correct.
Step-by-step explanation:
Descriptive adjectives are those adjectives that can be defined as the type of person, shape of a person, color of any thing , that is generally to describe a person, place, animal or thing.

The<u> old </u>man asked the <u>pretty </u>girl for food.
here, old is a descriptive adjective to describe a man.
And pretty is a descriptive adjective to describe a girl.
Hence, Option 'b' is correct.
Since there are 13 diamonds, there are 39 non diamonds (52-13)
To write a probability, you put the part over the whole
So you get 39/52 which is simplified to 3/4 so C
