To solve this, we need to figure out how many times 9% goes into 100%.

100% / 9% = 11.111

Since <u>9% of the pizzas equaled 27 pizzas</u>, we can <u>multiply 27 by the amount 11.111</u> to get the total number of pizzas (100%).

27 * 11.11 = 299.997, rounded to the nearest whole number is 300 Pizzas

vodka [1.7K]

Answer:

9\frac{1}{3}hours

Step-by-step explanation:

Let third cook take x hours to prepare the same number of  pies y alone

Let y be the number of pies

In 1 hour ,third cook prepare pies=\frac{y}{x}

One experienced cook takes time to prepare enough pies  =4 hours

In 1 hour , cook prepare pies=\frac{y}{4}

Another cook takes time to prepare same number of pies =7 hours

In 1 hour , another cook prepare pies=\frac{y}{7}

All three cooks take time to  prepare the same number of pies=2 hours

In 1 hour,all three cooks  prepare  pies=\frac{y}{2}

According to question

\frac{y}{4}+\frac{y}{7}+\frac{y}{x}=\frac{y}{2}

y(\frac{1}{4}+\frac{1}{7}+\frac{1}{x})=\frac{y}{2}

\frac{1}{4}+\frac{1}{7}+\frac{1}{x}=\frac{1}{2}

\frac{1}{x}=\frac{1}{2}-\frac{1}{4}-\frac{1}{7}

\frac{1}{x}=\frac{14-7-4}{28}=\frac{3}{28}

x=\frac{28}{3}=9\frac{1}{3} hours

Hence, the third cook takes time to prepare the same number of pies alone=9\frac{1}{3}hours

A museum has a 1/2 ounce piece of a precious metal. When the museum first received the piece, it had a value of $90. Its value h
Alex777 [14]
The current value of the precious metal is $144/oz

-First, you'd want to determine the original value per ounce since that's what the final unit being asked for is.

- Since the original value of the half ounce piece is given, this first step is fairly simple. You just double ninety.

- We now know that the metal was worth $180/oz when the museum first received it.

- We need to determine the current price of the metal now that is has had a twenty percent loss of value.

- My favorite way to factor in 20% is simply to divide by five since it's a lot more simple than finding the ratio of x$/1%

- $180/5=$36

- Thirty-six dollars is the price drop over the course of the museum possessing the precious metal.

- You now take $180-$36=$144

Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their ages is 92. Which equations co
Wewaii [24]

Answer:

h = Hannah's age

h - 2 = Anthony's age

Hannah is 47, Anthony is 45

Step-by-step explanation:

Using one variable and an expression with the same variable, you can find the sum of the siblings ages:

h = Hannah's age

h - 2 = Anthony's age

h + (h - 2) = 92

Combine like terms: 2h - 2 = 92

Add '2' to both sides: 2h - 2 + 2 = 92 + 2 or 2h = 94

Divide by 2: 2h/2 = 94/2

Solve for h:  h = 47 years old (Hannah)

h - 2 = 45 years old (Anthony)
