Answer:
0,00027 grams!
Step-by-step explanation:
This is a scientific notation problem.
When a number is followed by a
, it means that said number has one zero at the beginning.
In this case, the number is followed by
, so that means that 2.7 has four zeros at the beginning. So, 2.7x

Answer:
C.540 square cm
Step-by-step explanation:
The object is 6 times as big as the scale drawing. The area of the scaled object , to find the area of the object.. you have to multiply the area of the scaled object by the scale factor squared
15×6^2=15×36=540
The area of the object ia 540 square centimeters
R/9 = -21
Multiply by 9
r = -189
Answer:The formula for a combination of choosing r unique ways from n possibilities is:
nCr = n!
r!(n - r)!
where n is the number of items and r is the unique arrangements.
Plugging in our numbers of n = 10 and r = 0, we get
10C0 = 10!
0!(10 - 0)!
10C0 = 3,628,800
3,628,800
