Draw a diagram to illustrate the problem as shown below.
When the smaller gear rotates through a revolution, it sweeps an arc length of
2π(4) = 8π inches.
Part 1
The same arc length is swept by the larger gear. The central angle of the larger gear, x, is
7x = 8π
x = (8π)/7 radians = (8π)/7 * (180/π) = 205.7°
Answer: 205.7° (nearest tenth)
Part 2
When the larger gear makes one rotation, it sweeps an arc length of
2π(7) = 14π inches.
If the central angle for the smaller gear is y radians, then
4y = 14π
y = 3.5π radians = (3.5π)/2π revolutions = 1.75 revolutions
Answer:
The smaller gear makes 1.75 rotations
Answer:
the answer would be 80 :)
•Using the formula the first term is a1 = −3
•Using the formula the second term is a2 = −1
•Using the formula the third term is a1 = 6
•Common difference formula:
a2 - a1 = (-1) - (-3) = 2
Answer:
The equation needed is


Step-by-step explanation:
<u><em>The correct question is</em></u>
Clancy has 423 cups of yogurt to share with his friends at a party. Each guest will receive 1 serving of yogurt which is 3/4 of a cup. Write a multiplication equation to determine the number of people, p, who can be invited to the party
we know that
Each guest will receive 3/4 of a cup of yogurt
so
using proportion
Find out the number of people, who can be invited to the party, if Clancy has 423 cups of yogurt to share with his friends
Let
p -----> the number of people

-----> equation needed
