Answer:
Mean age = 1271.27
Step-by-step explanation:
No of children = 77
The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
= 77 × 16.51
= 1271.27
Mean age = 1271.27
Hello,
You have 7 balloons and in total, they cost 9.1. dollars. To find the unit price per balloon simply divide 9.1. by 7.
You'll get 1.3, OR 1.30.
To check your answer simply use inverse operations. Multiply 7 by 1.3 or 1.30 (it doesn't matter); you'll end up with the starting value 9.1.
Thus, the unit price per balloon is $1.30.

Answer:

Step-by-step explanation:
All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:
60° = [8x - 44]°
+ 44° + 44°
