Answer:
12. 6.4
13. 20
Step-by-step explanation:
This is the Pythagorean theorem, which says a^2+b^2=c^2. So for problem 12 we have 4^2+5^2=c^2. Since, 16+25=41, c=sqrt41 which is about 6.4. For problem 13 we have 15^2+b^2=25^2. Since 25^2-15^2=400, b=sqrt400 which is 20. Hope this helps!
8÷(2/5)=x
x=20

Step-by-step explanation:
Velocity ratios are calculated by dividing the driver gear by the driven gear. The driver gear or pulley is the one connected to the power - e.g. the pedals on a bicycle or the motor. To calculate the speed of the driven gear - multiply the speed of the driver gear by the velocity ratio.
HU is the hypotenuse!
- IU is the opposite side of angle H
- and i'm pretty sure HI is the adjacent side to angle H!
-the hypotenuse is always the longest side and will be the opposite side of the right triangle. so angle i is the 90 degree angle, so the opposite side is HU which is also the longest!
- angle H is marked and you can see the opposite side of it is IU which is one of the legs of this triangle.
- adjacent just means like next to or beside so the side HI is next to the angle H which is also a leg of this triangle.
i hope this helps!!
