Answer:
60% = 48
Step-by-step explanation:
30% is half of 60% which means we can basically just multiply the mass for 30% by 2 to get the mass for 60%.
↓
30% = 24
↓
24 * 2 = 48
↓
60% = 48

Answer:
81
Step-by-step explanation:
Assuming the ramp is against a wall or building at a 90 degree angle, then the 3 angles formed by the triangle within the ramp and wall are 9 +90 + x = 180 so 99 + x = 180 so x=81
17 tens is 170
So the unit form is 1 hundred, 7 tens, 0 ones
1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700.
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.
