Gwar [14]3 years ago

Answer:

120 different slates of candidates are possible.

Step-by-step explanation:

The order is important.

For example, a slate of John, Rose and Elisa means that John is the chairperson, Rose is the secretary and Elisa is the treasurer. If two of them are exchanged, their roles will also be changed. So we use the permutations formula to solve this question.

Permutations formula:

The number of permutations of x elements from a set of n elements is given by:

P_{n,x} = \frac{n!}{(n-x)!}

In this problem, we have that:

6 members will be chosen for 3 roles. So

P_{6,3} = \frac{6!}{(6-3)!} = 120

120 different slates of candidates are possible.

A bicycle tire has a diameter of 62 \text{ cm}62 cm62, start text, space, c, m, end text. What is the distance the bicycle tire
navik [9.2K]

Answer:

The distance bicycle tire travels is <u>1946.8 cm</u>.

Step-by-step explanation:

Given:

Diameter of bicycle tire = 62 cm.

The bicycle tire travels in 10 revolutions.

Now, to find the distance the bicycle tire travels in 10 revolutions.

Diameter = 62 cm.

Radius (r) = \frac{Diameter}{2}=\frac{62}{2}=31\ cm.

So, we get the circumference first by putting formula:

Circumference =2\pi r

Circumference =2\times 3.14\times 31\\\\Circumference =194.68\ cm.

Thus, we get the <u><em>circumference of tire 194.68 cm.</em></u>

<u><em>Number of revolutions the tire travels = 10.</em></u>

Now, to get the distance the bicycle tire travels we multiply circumference of tire by number of revolutions the tire travels:

194.68\ cm\times 10\\\\=1946.8\ cm.

Therefore, the distance bicycle tire travels is 1946.8 cm.

Sidana [21]

Answer:

Step-by-step explanation:

A shopper paid $2.52 for 4.5 pounds of potatoes. This means that the unit price for each potato would be

2.52/4.5 = 0.55556

Approximately $0.6 per pound.

The shopper paid $7.75 for 2.5 pounds of broccoli. This means that the unit price for each broccoli would be

7.75/2.5 = $3.1 per pound.

The shopper paid $2.45 for 2.5 pounds of pears. This means that the unit price for each pear would be

2.45/2.5 = $0.98 per pound

The least common multiple of two numbers is 60, and one of the numbers is 7 less than the other number. What are the numbers?
storchak [24]
Step One - List the factors of 60.
Step Two - Locate the factors that are seven apart from each other.

Factors of 60:
1 × 60
2 × 30
3 × 20
4 × 15
5 × 12
6 × 10

60 - 1 = 59
30 - 2 = 28
20 - 3 = 17
15 - 4 = 11
12 - 5 = 7
10 - 6 = 4

5 is 7 less than 12, and 60 is their least common multiple.
