RUR
Answer:
70.4 meters
Step-by-step explanation:
A to B: 40²+10²=c² = 1600+100=c² = 1700=c² = c=√1700 = 41.23
B to C: 25²+15²=c² = 625+225=c² = 850=c² = c=√850 = 29.15
41.23+29.15=70.38
25 is the greatest common factor of 75 and 25. 3 x 25 = 75.
Rewrite the right side of the equation
in the following way:
.
Then the equation is
and
.
So,
and
The equation has two solutions:
and
.
Answer:
10 teeth must go on the driven gear
Step-by-step explanation:
Let the number of teeth be x
In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that
17:5 = 34:x
∴ 10 teeth must go on the driven gear
hence ratio = 34:10
