Answer:
Step-by-step explanation:
Question 1
- x = 180° - 2*72° = 180° - 144° = 36°
Question 2
- x + 2(x/2) = 180°
- 2x = 180°
- x = 90°
Answer:
x=4
Step-by-step explanation:
1. 2x+4=12
2. 2x+4-4=12-4
3. 2x=8
4. 2x/2=8/2
5. x=4
Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
Answer:
The correct answer is 17/4, from 8 and 9 from the top PLUS 3 and 1 from the bottom.
Step-by-step explanation:
If we have a mathematical problem, it's important to follow all of the steps. In this instance, we have to reduce our fractions as well as pay attention to how they are grouped together before dividing out what remains. This means that if we break it into three groups - 8 and 9 11/2 groups - 3 and 1 17/4, then divide everything by 4 with a remainder of 2/4....we get a total of 17/4 remaining which is equal to 5 1/8 = 62%.
