faltersainse [42]

Complete Question:

A restaurant uses 4.375 pounds of cheese every 8 and 3/4 pizzas. At this rate how many pounds of cheese are used per pizza?

Answer:

0.5 pounds of cheese are used per pizza

Solution:

Given that,

A restaurant uses 4.375 pounds of cheese every 8 and 3/4 pizzas

Therefore,

$4.375\ pounds = 8\frac{3}{4}\ pizza \\\\4.375\ pounds = \frac{35}{4}\ pizza$

We have to find pounds used per pizza

Let "x" be the pounds used per pizza

Then,

$4.375\ pounds = \frac{35}{4}\ pizza \\\\x\ pounds = 1\ pizza$

By cross multiplying,

$4.375 \times 1 = x \times \frac{35}{4} \\\\x = 0.5$

Thus, 0.5 pounds of cheese are used per pizza

Write 17,390,000 in expanded form

scoray [572]

Answer:

The expanded form is:

17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

Step-by-step explanation:

Expanded form is a way of writing numbers with the mathematics value of digits.

Ex: 7,327 in expanded form is 7,000 + 300 + 20 + 7 = 7,327

So you can write any number in expanded form by adding the values of its digits places

Let us solve the question

The number is 17,390,000

∵ The first digit 1 is in ten-millions place

∴ Its value = 10,000,000

∵ The second digit 7 is in the millions place

∴ Its value = 7,000,000

∵ The third digit 3 is in the hundred-thousands place

∴ Its value = 300,000

∵ The fourth digit 9 is in the ten-thousands

∴ Its value = 90,000

Add all of them

∴ 17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000

The expanded form is

17,390,000 = 10,000,000 + 7,000,000 + 300,000 + 90,000
