marta [7]

Answer:

The answer would be 8.

Step-by-step explanation:

This is a percentage question, and I have struggled with these before but this is the easiest way to solve it given these certain criteria.

Alright, so it's given that:

A) 90%= an A grade

and

B) This is an 80-question test.

Given these, we can do the following:

90% times 80, which equals 72.

Just to check, we know that to convert percentages to fractions, we move the decimal two spots to the left, therefore 90%= 0.90, or 0.9. We take 72 and divide it by 80, and we get 0.9, thus showing that it is correct.

Then, we do 80-72 and using simple math we get 8.

A Chef prepares and evenly divides s ounces of beef stock into 3 smaller pans. The chef uses 8 ounces of beef stock form one of

saw5 [17]

Answer:

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

The total number of ounces of beef stock = 126

Step-by-step explanation:

Given:

Total ounces of beef stock = $s$

The chef divided the beef stock evenly into 3 smaller pans.

The chef then uses 8 ounces from one of the smaller pans.

Ounces of beef stock left in the smaller pan = 34

Solution:

Total ounces of beef stock = $s$

Ounces of beef stock in each smaller pan = $\frac{s}{3}$

Ounces of beef stock used by the chef from the smaller pan = 8.

The ounces of beef stock left in the smaller pan will be given as:

⇒ $\frac{s}{3}-8$

Ounces of beef stock remaining in smaller pan = 34

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

Solving for $s$ .

Adding 8 both sides.

⇒ $\frac{s}{3}-8+8=34+8$

⇒ $\frac{s}{3}=42$

Multiplying both sides by 3.

⇒ $3\times \frac{s}{3}=42(3)$

∴ $s=126$

Thus, total number of ounces of beef stock = 126
