Answer:
A) Divide 20 by 2 and then add 8 to the result
Step-by-step explanation:
Answer:
( cos40° + isin40°)
Step-by-step explanation:
To divide
= 
[ cos(x₁ - x₂) + isin(x₁ - x₂)
Given
= 
( cos(90 - 50)° + isin(90 - 50)°
= ( cos40° + isin40° )
Ex.
f + g = y
-----------
3
3(f+g) = (y) 3
--------
3
f + g =3y
f - f + g = 3y - f
g = y - f
Answer:
Lana can put 24 drops of bubble bath for her sister
Step-by-step explanation:
If package says to put in a drop of bubble bath for every half gallon of water in the bath tub.
If the bathtub can hold 12 gallons of water
There are 12÷1/2 gallon
=12×2/1
=24
It means there are 24 half gallons in the bathtub
If every half gallon of water requires a drop of the bubble bath
Then,
24 half gallons of water requires 24 drops of the bubble bath
