All you have to do is divide the 120 by 4 because you will be splitting it up into a individual hour. So 120 divided by 4 = 30.
The plumber charges $30/hour.
This question is asking us to add the numbers together to create the sum of drinks.
210 + 195 = 405
Why tho?
1 : 0 + 5 = 5
2 : 1 + 9 = 10 Carry the one.
3 : 2 + 1 = 3 + 1 = 4
=405
Hope helps!-Aparri
Answer:

Add all of the integers together then divide by 4 bc thats how many integers there are in order to get the mean.
Answer:
482 scones.
Step-by-step explanation:
Given:
Cost of each scones = $1.50
Their current profits are $578.40 which is 80% of his total sales.
Question asked:
How many scones have they sold ?
Solution:
Let total number of scones sold = 
Cost of 1 scone = $1.50
Cost of scones = $1.50 
(Unitary method)
80% of his total sales = $578.40 (given)
Dividing both sides by 1.2
Thus, they have sold 482 scones.
Use the Pythagorean theorem since you are working with a right triangle:
a^2+b^2=c^2a2+b2=c2
The legs are a and b and the hypotenuse is c. The hypotenuse is always opposite the 90° angle. Insert the appropriate values:
0.8^2+0.6^2=c^20.82+0.62=c2
Solve for c. Simplify the exponents (x^2=x*xx2=x∗x ):
0.64+0.36=c^20.64+0.36=c2
Add:
1=c^21=c2
Isolate c. Find the square root of both sides:
\begin{gathered}\sqrt{1}=\sqrt{c^2}\\\\\sqrt{1}=c\end{gathered}1=c21=c
Simplify \sqrt{1}1 . Any root of 1 is 1:
c=c= ±11 *
c=1,-1c=1,−1
