Answer:

21.5secs

Step-by-step explanation:

Given the function that models the height of an object as

h(t) = -16t^2+ 344t

The object hit the ground at h(t) = 0

Substitute

0 = -16t^2+ 344t

16t^2 = 344t

16t = 344

t = 344/16

t = 21.5

Hence it takes 21.5secs for the object to hit the ground

Yuki888 [10]

Answer: 6 cups of ketchup per cup of mustard

Step-by-step explanation:

Given : The recipe calls for 3 cups of ketchup for every $\dfrac12$ cup of mustard.

That means , for $\dfrac12$ cup of mustard. we need 3 cups of ketchup.

By using proportions, if we multiply 2 on both sides ,we get

for $\dfrac12\times 2$ cup of mustard. we need $3\times 2$ cups of ketchup.

⇒ for $1$ cup of mustard. we need $6$ cups of ketchup.

Hence, the required rate = 6 cups of ketchup per cup of mustard
