For 2/5 cup, vanilla needed = 8 teaspoons
so, for 1 cup, it would be: 8 / 2/5
⇒8 × 5/2
⇒40/2
⇒20

In short, Your Answer would be 20 teaspoons

Hope this helps!

8 teaspoons would be needed for 2/5 cup.

Ratio of teaspoons to cup = 8 teaspoons / (2/5) cups

= 8 * 5/2 teaspoons/cup

= 20 teaspoons/cup

So the unit rate is 20 teaspoons per cup.

Hope this explains it.

Answer:

h(4) = –12

Step-by-step explanation:

⇒ What the question is asking is that when the function h(n) = –2n(2) + 4 is h(4), what will the function repond to when solving for h(4)? So, solve for the function h(4):

h(4) = –2n(2) + 4

⇒ Since n was replaced with 4 in the function h(4), substitute any n for 4 into the function:

h(4) = –2(4)(2) + 4

⇒ Simplify:

h(4) = –16 + 4

⇒ Solve:

h(4) = –12

Answer: h(4) = –12

I hope you understand and that this helps with your question! :)
