Answer: 9
Step-by-step explanation: 4.5=.5xZ. 4.5/.5=9=z
Answer:
- abscissa <em>t</em> (or <em>x</em>) as the “time since beginning of journey”, with hours h as unit
- ordinate <em>d</em> (or <em>y</em>) as the “distance traveled”, with miles mi as unit
Step-by-step explanation:
The graph will look like a diagonal straight line from (0 h, 0 mi) to (2 h, 100 mi). The slope of this line is 50 mph.
In order to calculate this, you need to solve :

x 100 %
= 0.2 / 9.87 x 100 %
= 2.02 %
Hope this helps
<h3>
Answer: 7.4 hours</h3>
==========================================================
Explanation:
Add up the percentage values:
25+20+6+6+6 = 63
This means 63% of the trip was driven by anyone but Dan. That must mean 100-63 = 37% of the trip is how much Dan drove.
Apply this percentage to the 20 hour duration
37% of 20 = 0.37*20 = 7.4 hours represents how long Dan drove.
extra notes:
- 7.4 hours = 7 hours, 24 minutes because 0.4 hours = 0.4*60 = 24 minutes
- 7.4 hours = 7 hrs + 24 min = 7*60+24 = 444 minutes
36 walls can be painted in 8 hours. 4 1/2 times 8 = 36
