The mean number of radioactive atoms that decay per day is 81.485.
Answer:
B. 5
Step-by-step explanation:
-15 / -3
Both are negative so they cancel each other out.
15 / 3 equals 5
Answer:
Subtraction.
Step-by-step explanation:
As the question has said, 7/8 ft shorter than table which means you must substract it from the table's height.
For example :
if a stool is 7/8 ft longer than table which means you must add up the table's height
0.2+ 0.05 My response is to short..sooooo hope u like my answer
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
