P=26=2*(l+L)
⇒ l+L=26:2=13 feet
l=3, L=10

A=l*L=30=10*3

⇒ l=3 feet
L=10 feet

How to convert 3.248 repeating decimal with 48 repeating into a simplified fraction

Sonja [21]

Answer:

$x=\frac{536}{165}$

Step-by-step explanation:

Let X be the value of 3.2484848.... infinite times

Multiply by 100

$x=3.24848....\\100x = 324.8484.....$

Subtract to get

$100x-x = 324.8484...-3.248484....\\99x = 321.60\\x=\frac{321.6}{99} \\x=\frac{1072}{330} \\x=\frac{536}{165}$

Thus the number 3.248 repeating decimal with 48 repeating in fraction form is

$\frac{536}{165}$

Estimate 80,767 - 37,291 by first rounding each number to the nearest thousand.

N76 [4]

Answer:

$44000$

Step-by-step explanation:

Given the following question:

$80767-37291$

To estimate by the nearest thousand, we have to look at the thousand's place value and then look at the number next to it, to see if it's greater than five.

$80767-37291$

$80767$

$7 > 5$

$81000$

$37291$

$2 < 5$

$37000$

$81000-3700=44000$

$=44000$

Hope this helps.
