Leah has a flower vase in the shape of a rectangular prism with a square base. The vase has a height of 12 inches.
There are flowers and some water in the vase. The water is
getting low, so Leah takes the vase to the sink and begins to
add water.
• After 5 seconds, the height of the water in the vase is 3.85
inches.
After 10 seconds, the height of the water in the vase is 5.7
inches.
Write a linear function that models the relationship between the number of seconds the water has been running and the height of the water in the vase

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

coins of silver or gold

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
