Shalnov [3]

Answer:

65% of the beads were used to make the bracelet.

Step-by-step explanation:

40% of the beads were blue which means 60% of the beads were red. If all the blue beads were used that means 40% was used so you add the 25% of the red beads that were used which is why the answer is 65%.

If a student didn’t understand proportional relationships, how would you explain it to them?
kirill [66]

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!

ivolga24 [154]

Answer:

Step-by-step explanation:

Ordered pair (0, 0) & (0.5, 2.5)  will fall on the line of graph

Step-by-step explanation:

Megan expects to save an average of 5 dollars per week from her babysitting earnings.

=> Saving Per  week  = 5 $

Saving in 0.5 Week = 0.5 * 5 = 2.5 $

hence ordered pair (0.5, 2.5)  will fall on the line of graph

Saving in 3 Week = 3 * 5 = 15 $

Hence (3, 18) will not fall on  line

Saving in 0 Week = 0.5 * 0 = 0 $

hence ordered pair (0, 0)  will fall on the line of graph

Saving in 4.5 Week = 4.5 * 5 = 22.5 $

Hence (4.5, 30) will not fall on  line
