Emma has a spool of ribbon that has 5 meters on it. she cut a length of ribbon that was 0.9 meters long. then she cut another length that was 1.5 meters long. how much of the ribbon is left on the spool?

2.6 meters.

Step-by-step explanation:

5-0.9 is 4.1, minus 1.5 is 2.1.

2.6 meters left

Step-by-step explanation:

One way you can solve this problem is by putting it into an equation and finding the difference.

The equation would be 5 - 0.9 - 1.5 = ?

5 - .9 = 4.1

4.1 - 1.5 = 2.6

therefore, 2.6 meters of ribbon will be left on the spool.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
