<em>The app's estimate was 38.4 minutes.</em>
Step-by-step explanation:
Suppose, the app's estimated time was 
minutes.
Given that, it took 48 minutes to drive downtown. So, <u>the error in estimated time by the app</u> 
minutes.
It is also given that the error was 20%. So, <u>the amount of error</u> 
minutes.
Thus, the equation will be......
So, the app's estimate was 38.4 minutes.

Step-by-step explanation:
1. 2.0 x 10^-2
2. 2.2 x10^6
3. 2.0 x 10^4
Just covert each until you reach the end, like you know that there are 356 days in a year and 100 years in a century.

I'm pretty sure that it would be 1,000...
Answer:
Option (D). 110°
Step-by-step explanation:
Since EB and AD are diameter,
= 
= 180°
= 180° -------(1)
And 
180° = 40° + 
= 140°
Since, 
= 140° [Given 
]
= 70°
From equation (1),
= 180° -
= 180°- 70°
Therefore, measure of arc(EDC) = 110°
Option (D) will be the answer.
