Answer:
1 / 20
Step-by-step explanation:
Brian = 11.74 seconds
Luis = 11.69 seconds
Difference between their times :
11.74 - 11.69 = 0.05
Expressed as a fraction of a second :
0.05 / 1 = (0.05 * 100) / (1 * 100) = 5 /100 = 1/20
Answer:
Step-by-step explanation:
The interior is a parallelogram when adjacent angles are supplementary. This requires ...
(x -30)° + (x +50)° = 180°
2x + 20 = 180 . . . . . . . . . . . collect terms, divide by °
2x = 160 . . . . . . . . . . . . . . . subtract 20
x = 80 . . . . . . . . . . . . . . . . . divide by 2
Then the angle x+50 is ...
(x +50)° = (80 +50)° = 130°
This is also the measure of the angle marked y.
For the lines to be parallel, x = 80, y = 130°.
1 hour = 60 minutes
2 3/4 hours = 165 minutes
The area of the composite figure can be calculate
120 pi x 5.1 1922.6547
1922.6547 divided by 7.4 =259.8182
259.8182 + 3.2 = 263.0182
