Some native american tribe made jewelry with dentalia shells. each denalia shell is 2 inches long how much longer would a necklace made with 25 shells be than a necklace made with 20 shells?

10 inches

Step-by-step explanation:

We know that each single Denalia shell is 2 inches. So let's calculate how many inches a 25 shell necklace would be

25(number of shells)×2(inches per 1 shell) = 50in

Next let's find the second necklace with 20 shells

20(number of shells) × 2(inches per 1 shell) = 40in

Finally we take the difference between the two

50in - 40in = 10 inches

Thus, the difference between a 25 shell necklace and a 20 shell necklace is 10 inches.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
