Stefanie is painting her bedroom. She can paint 12 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one

aalyn [17]

Answer:

$31\frac{2}{3}$

Step-by-step explanation:

since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3

$12\frac{2}{3}$ ÷2= $6\frac{1}{3}$

$12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}$

$12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}$

Write two equivalent expressions to represent the area of the rectangle below.

Goshia [24]

Answer:

$A=(n-3)2\ units^2$

$A=(2n-6)\ units^2$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length of rectangle

W is the width of rectangle

In this problem we have

$L=(n-3)\ units\\W=2\ units$

substitute

$A=(n-3)2\ units^2$

Apply distributive property

$A=2(n)-2(3)$

$A=(2n-6)\ units^2$

When a decimal is written in word form, what indicates whether the number can be written as a mixed number or as a fraction less

vekshin1

9514 1404 393

Answer:

"and"

Step-by-step explanation:

Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.

Examples:

one and three tenths = 1 3/10

thirty-one thousandths = 31/1000
