Let’s find the scale factor (the number each number on the left has been multiplied by)
14/10 = 1.4
The scale factor is 1.4 so 10 has been multiplied by 1.4 to get 14

so you are now going to do 1.4 * 4 = 5.6

5.6 is your answer!!

In the video Mouse Count, Miss Ashley read a book about a snake that captured mice and placed them one-by- one in a jar for his
spin [16.1K]

Based on the fact that the snake was placing the mice one - by - one into a jar, this is A. Combining sets.

<h3>What does combining sets entail?</h3>

When sets are combined, it means that numbers from a certain set of variables are combined with those from another set.

The snake had captured the mice separately which means they were in different sets. Putting them into one jar means they are being combined so this is combining sets.

The wildflowers at a national park have been decreasing in numbers. There were 1200 wildflowers in the first year that the park
bonufazy [111]

Year      New flowers

1                 1200

2                 300

3                   75

There were 1200 wildflowers in the first year that the park started tracking them. Since then, there have been one fourth as many new flowers each year

Initially there are 1200 flowers and start decreasing by \frac{1}{4}

So first term is 1200 and common ratio is \frac{1}{4}.

Its a geometric sequence so summation becomes

i =1∑ ∞ 1200(\frac{1}{4})^{i-1}

Now we find the sum

We use sum formula

Sum = \frac{a}{1-r}

Where a is the first term , a= 1200

r is the common ratio , r= 1/4

Sum = \frac{1200}{1-(\frac{1}{4})}

Sum = \frac{1200}{\frac{3}{4}}

Sum = 1600 wildflowers
