A 3 L bottle of oil costs $36 and contains 12 cups. Dinesh puts 1 cup of oil, 10 garlic gloves and 1 cup of lemon juice in each
lys-0071 [83]

Answer:

$15

Step-by-step explanation:

Let's start by figuring out how much 1 cup of oil costs.

12 cups of oil is 36$

Let's set up a proportion.

12/36=1/x

Cross Multiply

12x=36

Divide both sides by 12.

x=3

1 cup of oil is $3.

Dinesh makes 5 batches of hummus, and each batch requires 1 cup of oil.

5*1=5

This means he needs 5 cups of oil.

5*3=15

He used $15 worth of oil in the 5 batches of his recipe.

However, since it is impossible to buy 5/12 bottles of oil, he would have needed to spend $36.

Which value of x is in the domain of f(t) = squared x - 7
zloy xaker [14]

Given:

The given function is:

f(x)=\sqrt{x-7}

To find:

The value of x that is in the domain.

Solution:

Domain is the set of input values.

We have,

f(x)=\sqrt{x-7}

We know that the square root is defined for non negative values. So,

x-7\geq 0

x\geq 0+7

x\geq 7

Thus, the domain of the given function is all real number that are greater than or equal to 7.

In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, x=8 is in the domain of the given function.

Therefore, the correct option is A.
