<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
Answer:
nnether do i
Step-by-step explanatiyes
36 and 100 are both perfect squares
the factorization of x^2-y^2 is (x+y)(x-y)
substitute x^2 with 36x^2 and y^2 with 100y^2:
<span>36x^2-100y^2=
(6x+10y)(6x-10y) or
4(3x+5y)(3x-5y)</span>
So,
We know that a * 1 = a.
Obviously, a times any quantity greater than 1 will result in a larger (or smaller, in the case of integers) number.
So 0.4 * 1.8 > 0.4.
