The correct option is "d".
Given that L = 0.8T²
length of pendulum = 30ft

L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
<span>So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.</span>

A recipe for ricotta cheese calls for 3/4 cup of whole milk for every 1/8 teaspoon of salt how much whole milk should be used fo
Luba_88 [7]

Answer:

<u>6 cups</u> of whole milk is used for every teaspoon of salt.

Step-by-step explanation:

Given:

A recipe for ricotta cheese calls for 3/4 cup of whole milk for every 1/8 teaspoon of salt.

Now, to find the cup of whole milk should be used for every teaspoon of salt.

So, to get the cup of whole milk used we use unitary method:

For every 1/8 teaspoon of salt cup of whole milk used = 3/4 cup.

Thus for every teaspoon of salt cup of whole milk used = 3/4 ÷ 1/8.

=\frac{3}{4}\times \frac{8}{1}  (changing the division to multiplication the fraction reciprocals.)

=\frac{24}{4}

=6\ cups.

Therefore, 6 cups of whole milk is used for every teaspoon of salt.
