107360 yards = 31 miles = 1 hour
1 second = 1789.3333333 yards
Answer:
1 = 128 degrees
2 = 52 degrees
3 = 47 degrees
4 = 133 degrees
5 = 81 degrees
Step-by-step explanation:
angle 2 and 52 degrees are corresponding angles so they are equal.
angle 3 and 47 degrees are corresponding angles so they are equal.
angles 1 and 2 are supplementary angles so their sum is 180 degrees.
angles 3 and 4 are supplementary angles so their sum is 180 degrees.
angle 5 = 180 - 52 - 47 = 81 degrees
Answer:
Step-by-step explanation:
<u>Ball dropped and we start count from that moment:</u>
- 160 ft down
- 80 ft up and down
- 40 ft up and down
- 20 ft up and down, end
<u>Total distance:</u>
- 160 + 80*2 + 40*2 + 20*2 = 440 ft
Answer:
n=35; q=33 coins.
Step-by-step explanation:
1) if number of nickles is 'n' and the quaters is 'q' then it is possible to write:
n+q=68 - 'she counted 68 coins...' - the 1st equation of system;
0.25q+0.05n=10 - '10$ in it' - the 2d equation of the system.
2) it is possible to make up and solve the next system of two equations:
