Answer:

k = 5

Step-by-step explanation:

When a certain number n is multiplied by a scale factor k, the  final number is given by

n'=kn

and the final number will be:

- Larger than the original number if |n'|>|n|

- Smaller than the original number if |n'|

In this problem, the number n represents the size of the decoration.

If we apply the 4 scale factors given, we have:

- If k=5, then n'=5n: this means that the final decoration is larger than the original decoration --> this is the correct option

- If k=1, then n'=n: so the final decoration has same size as the original decoration

- If k=1/5, then n'=\frac{1}{5}n: so the final decoration is smaller than the original decoration

- If k=-1/5, then n'=-\frac{1}{5}n, so the final decoration is smaller and inverted

Answer:

100

Step-by-step explanation:

Mixed candy question... Skittles jar... to be filled with Jelly beans.

Let's first calculate the volume of the jar.  We'll assume it's a regular cylindrical prism jar, unlike the one on the photo which is narrower on top.

V = π * r² * h = π * (3.5)² * 11.5 = 140.875 π = 442.6 cubic cm

Now, we don't have the precise measurement of a jelly bean, but we know it's roughly 2-3 cubic cm.  The precision isn't needed to answer this question, just to have a rough idea... it's no 300 cu cm per jelly bean.

So, let's assume a 3 cu cm per jelly bean (2 cu cm wouldn't the final answer)....

442.6 / 3 = 147.5 jelly beans, approximately.

So, can they fit 100,000?  No

Can we fit 10,000 in there?  No

Can we fit 100?  Yes.

Can we fit 1?  Certainly

The most reasonable lower-limit would then be 100.

How can I solve 4x^2 + 12x > -x -3
Damm [24]

He have the following:

4x^2+12x>-x-3​

solving:

\begin{gathered} 4x^2+12x+x+3>-x-3+x+3​ \\ 4x^2+13x+3>0 \\ \text{factoring} \\ (4x+1)(x+3)>0 \\ (4x+1)>0\rightarrow4x+1-1>-1\rightarrow\frac{4x}{4}>-\frac{1}{4}\rightarrow x>-\frac{1}{4} \\ (x+3)
