of a hour. Compute the unit rate by setting up a complex fraction and simplifying.
A)
1 yards per hour
B)
2 yards per hour
C)
5 yards per hour
D)
10 yards per hour
Answers
Answer:
Choice B: 2 yards per hour.
Step-by-step explanation:
In order to compute the unit rate we have to divide the number of yards watered by the amount of hours taken:
Take the reciprocal of the denominator of the expression and we get:
Which simplifies to
Thus Unit rate = which is choice B.

Answer: A solid ring
Step-by-step explanation:
From the given diagram, if the circle revolves about the vertical dashed line.
We can see that there is some distance between the circle and the vertical line, which is represented by horizontal dashed line.
So, when it revolves about the vertical dashed line, it will form a torus (donut shape).
A torus is nothing but the solid ring .
- A torus is a surface of revolution generated by revolving a circle in three-dimensional space about an axis with the circle such that the axis of revolution does not touch the circle.
If a solid ring is a TOR (tore in french , a room air )

Answer:
- 1 necklace: 24 blue, 30 green
- 2 necklaces: 12 blue, 15 green (each)
- 3 necklaces: 8 blue, 10 green (each)
- 6 necklaces: 4 blue, 5 green (each)
Step-by-step explanation:
The greatest common factor of 24 and 30 is 6. The divisors of 6 are 1, 2, 3, and 6. Those are the numbers of identical necklaces that might be made from the beads. The number of beads of each color is found by dividing the total number of beads by the number of necklaces being made.
The possible numbers of necklaces are 1, 2, 3 or 6.
The numbers of (blue, green) beads on each will be (24, 30), (12, 15), (8, 10), or (4, 5), respectively.
_____
The greatest common factor (GCF) is the product of the common prime factors.
24 = 2^3×3
30 = 2×3×5
The prime factors in common are 2 and 3, so the GCF is 2×3 = 6.
