lorasvet [3.4K]

The answer is, 4 + 8 + 12 + 16 ... rule is 4n.

one square has 4 toothpicks, then you added 4 picks (because you started with zero squares).

4 squares have 12 toothpicks, then you added 8 toothpicks to pass from one square to 4 squeres.

Chris mixes 4cups of cereal 3cups of pecans 2 cuos of raisins how can you use ratios to compare quantities of each ingredient an

andrew11 [14]

Answer:

cereal : pecans : raisins = 2 : 1.5 : 1

Step-by-step explanation:

Given:

The amount of cereal in snack mix = 4 cups

The amount of pecans in snack mix = 3 cups

The amount of raisins in snack mix = 2 cups

Therefore,

The total amount of snack = 4 cups + 3 cups + 2 cups = 9 cups

Now,

The ratio is given as:

= $\frac{\textup{Amount of a substance in a mix}}{\textup{Total amount of mix}}$

therefore,

Ratio of cereal in snack mix = $\frac{\textup{4 cups}}{\textup{9 cups}}$

and,

Ratio of pecans in snack mix = $\frac{\textup{3 cups}}{\textup{9 cups}}$

Ratio of raisins in snack mix = $\frac{\textup{2 cups}}{\textup{9 cups}}$

Now,

we have ratio as:

4 : 3 : 2

i.e cereal : pecans : raisins

taking 2 common

we get

2 : 1.5 : 1

therefore,

the maximum amount
