The ratio is 2:5 red beads to blue beads. If you have a TOTAL of 21 beads, how many are red, and how many are blue beads?

Answer:

Number of red beads = 6

Number of blue beads = 15

Step-by-step explanation:

Number of total beads = 21

Ratio of red beads to the blue beads = 2 : 5

Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]

                                                                  = [tex]\frac{2}{7}\times 21[/tex]

                                                                  = 6 beads

Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]

                                      = [tex]\frac{5}{7}\times 21[/tex]

                                      = 15 beads

Therefore, number of red beads = 6

And number of blue beads = 15

The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same number of slices, giving them a total of 24 slices.
The Wilson family also orders several large pizzas from the same pizza restaurant. They also cut the pizzas so that all their pizzas have the same number of slices. For the Wilson family, the equation y = 10x represents the relationship, where x represents the number of pizzas and y represents the number of total slices.
Which statements best describe the pizzas bought by the Hernandez and Wilson families? Select two options.
For the Hernandez family, the equation y = 3x represents the relationship between the number of slices and number of pizzas, where x represents the number of pizzas and y represents the number of total slices.
For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line.
The Hernandez family’s slices are smaller than the Wilson family’s slices.
If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices.
The constant of proportionality is 10 for the Wilson family, but cannot be determined for the Hernandez family.
