Activity A pom-pom manufacturer makes each of its pom-poms with 35% white strands (w), 25% blue strands (b), and 40% red strands
Reika [66]

Answer:

To make a pair of pom-poms, we will need 56 white strands, 40 blue strands and 64 red strands

Step-by-step explanation:

Here in this question, we are interested in knowing the number of strands of each color needed to make a pair of pom-poms.

Since we are making a pair of pompoms and each pom-pom has 80 strands, the total number of strands for a pair will be 2 * 80 = 160 strands

Now, we want to use 35% white strands

So the number of white strands will be;

35/100 * 160 = 56 white strands

25% blue strands will be ;

25/100 * 160 = 40 blue strands

40% red strands will be;

40/100 * 160 = 64 red strands

Slope between two points:

Slope=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

(x_{1},y_{1} )=(-8,-3), (x_{2},y_{2} )=(-3,4)

m=\frac{4-(-3)}{-3-(-8)}

Refine.

m=\frac{7}{5}
