there are five bells which ring at interval of 4,5,12 and 15 minutes respectively at what minute those bells ring at the same ti

Rus_ich [418]

<h3>Answer: 60 minutes</h3>

=====================================================

Explanation:

Let's find the LCM of 4 and 5, which are the first two items of the list.

multiples of 4 are: 4,8,12,16,20,24,...
multiples of 5 are: 5,10,15,20,25,...

The smallest item in each list is 20, so the LCM of 4 and 5 is 20.

We can replace the "4,5" in the list "4,5,12,15" with "20". So our new list would be "20,12,15".

We then repeat the process of finding the LCM of the first two items

multiples of 20 are: 20,40,60,80,...
multiples of 12 are: 12,24,36,48,60,72,...

LCM of 20 and 12 is 60.

The list "20,12,15" condenses to "60,15".

Repeat this process of finding the LCM once more and you'll find the overall LCM is 60.

Therefore, the LCM of the entire set {4,5,12,15} is 60. This is the smallest multiple shared by all four values. Interestingly enough, the outer values pair up to multiply to 60, and so do the inner values.

4*15 = 60

5*12 = 60

The bells ring together every <u>60 minutes</u>

In other words, all of the bells ring together at the same time every hour (perhaps at the top of every hour; eg at 7:00 pm and at 8:00 pm, etc).

Mimi needs eleven 18-inch pieces of rhinestone ribbonShe purchased 5 yards of the ribbon shown at the rightWhat is the total amo

GalinKa [24]

Answer:

5.5 yards.

Step-by-step explanation:

We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.

First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:

$\text{Amount of total ribbon in inches}=11\times 18\text{ inches}$

$\text{Amount of total ribbon in inches}=198\text{ inches}$

We know that 1 yard equal to 36 inches. To convert 198 inches into yards, we will divide 198 by 36 as:

$\text{Amount of total ribbon in yards}=198\text{ inches}\times \frac{1\text{ Yard}}{\text{36 inches}}$

$\text{Amount of total ribbon in yards}=\frac{1\text{19 Yard}}{36}$

$\text{Amount of total ribbon in yards}=5.5\text{ Yards}$

Therefore, the total amount of ribbon that Mimi needs is 5.5 yards.

Terminating Decimal between .5 and .6

iragen [17]

A terminating decimal is a number with a finite number of decimals that does not continue endlessly. We'd like to know whether the decimal value obtained by dividing the fraction 5/6 (5 6) is terminating or non-terminating.
