The numbers are 18 and 12
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
Answer:
A
Step-by-step explanation:
a tennis ball has a diameter of about 2.5 inches
so volume of a tennis ball is: 4/3 x pi x r^3 = 8.2 cubic inches ( estimating you could say 8 cubic inches
1 cubic foot = 1728 cubic inches
so you could fit 1728/8 = 216 tennis balls in a cubic foot.( estimated)
you would then need to calculate the volume of the room
lets say a small room is 9 foo by 9 foot by 8 feet high
9 x 9 x 8 = 648 square feet
now multiply the 216 by the square feet of the room
216 * 648 = 139,968tennis balls
now because they are round, there will be empty space around them
so you could estimate about 139,000 tennis balls would fit I a 9 x 9 room that is 8 feet high.
You didn't give the dimensions of the room, but this gives you the idea of how to estimate
For an exponential function the y-intercept is the "initial value" (not the common ratio).

will always be 2. if that's what you need
note that

because anything to the power of zero equals 0 (mathematically it's deciding something by itself)
