HELP I REALLY NEED HELP

Answer: 72 inches squared

Step-by-step explanation:

So, the real floor of a classroom is 36 feet by 32 feet.

And the scale drawing, has length of the classroom equal to 9 inches.

What is the area in square inches of the floor in the scale drawing

1 foot = 12 inches

The length of the classroom, measured in feet, has been multiplied by 12, to get converted in inches. After that, it has been divided by a number, a proportion, to get to 9 inches.

36feet * 12 / x = 9 inches

432 inches / x = 9 inches

Now, to solve for x, we can cross-multiply

432 inches = 9x inches

Divide 9 inches on both sides.

x = 48

To solve the exercise, we need to calculate the floor's area in the scale drawing.

We have the length = 9 inches.

Now, let's calculate the width

Width = 32 feet * 12 / 48

Width = 384 inches / 48

Width = 8 inches

Area = Length * Width

Area = 9 inches * 8 inches

Area = 72 inches squared

What is the relationship between the values of the given digits 7's in 7'700

GaryK [48]

Step-by-step explanation:

The given number is 7700.

We need to find the relationship between the values of the digit 7s in it.

The digit in the extreme left is 7 and second no is again 7.

The place value of first 7 is 7000

The place value of second 7 is 700.

Taking ratio of place value of 7 in first 7 and for second 7 as follows :

$R=\dfrac{7000}{700}\\\\R=10$

So, value of first 7 is 10 times that of the value of second 7.
