Answer:

4 rolls of blue ribbon,

5 rolls of silver ribbon,

3 rolls of yellow ribbon.

Step-by-step explanation:

We have been given that Mrs Grey is buying decorative ribbon of three different colors: blue, silver, and yellow. Blue ribbon is sold in rolls of 15 meters, silver is sold in rolls of 12 meters, and yellow comes in rolls of 20 meters.

As Mrs. Grey needs to have same length of each ribbon, so we will find the least common multiple of 15, 12 and 20.

Multiples of 15 are: 15, 30, 45, 60, 75, 90,...

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,...

Multiples of 20 are: 20, 40, 60, 80,100,...

We can see that 60 is the least common multiple of 15, 12 and 20.

$\text{The smallest number of rolls of blue ribbon}=\frac{60}{15}=4$

Therefore, Mrs. Grey should buy 4 rolls of blue ribbon.

$\text{The smallest number of rolls of silver ribbon}=\frac{60}{12}=5$

Therefore, Mrs. Grey should buy 5 rolls of silver ribbon.

$\text{The smallest number of rolls of yellow ribbon}=\frac{60}{20}=3$

Therefore, Mrs. Grey should buy 3 rolls of yellow ribbon.

Find the 6th term in this series: {1, 15, 45, 135, ...} *

Luden [163]

Alright, since after the second term, the pattern is consistent, we will be using the 3rd and 2nd terms in the formula, instead of the 2nd and 1st.
1. divide the 3rd term by the second term. 45/15=3
2. Check the pattern by applying this method to the 4th and 3rd terms. 135/45=3 This means is is in fact G.S.
3. Now we go back to the traditional formula, which would be 1st term*r^n-1
4. Work it out. The r in the formula represents the 3, which we worked out. The n in the formula represents the term your trying to find. 15*3^6-1=3645
Your answer for the 6th term should indeed be 3645, which may sound odd, but it's right.
~Hope this helps!

Lin rode her bike 2 miles in 8 minutes. How many miles did she go in 4 minutes?

Nuetrik [128]

Answer:

1 mile: 4 minutes

Step-by-step explanation:

This problem can be expressed with a simple ratio: 2:8

Now, thankfully the numbers are even so we just need to simplify the ratio to get our answer. Ratios work like fractions in that manner. So we just need to divide both sides by 2 to get the _:4 result.

This gives us a ratio of 1:4. Therefore, Lin travelled 1 mile in 4 minutes.
