She spent 19.82 in all
Step-by-step explanation:
I added them
It is given in the question that
For th first inequality, we divide both sides by 2, and for second, we subtract 3 to both sides, that is
So the required inequality is
![(- \infty, -9] U (2, \infty)](https://tex.z-dn.net/?f=%28-%20%5Cinfty%2C%20-9%5D%20U%20%282%2C%20%5Cinfty%29)
Correct option is B
Dimensions of the room------------------- >16*13
1 in---------------- >0.0833333 foot
3 in----------------- >x
x=3*.0833333=0.25 ft
Let
<span>C-------------- > dimensions of the piece of carpet that Charlotte must purchase
C-------------- > (16+2*0.25)*(13+2*0.25)---------- > (16.50)*(13.50)=222.75 ft</span>²
<span>
The answer a the question 1) is 16.50 feet X 13.50 feet</span>
The answer a the question 2) is 222.75 ft²
<span>3. How many hours should it take for the four-person crew to lay the flooring in Charlotte's bedroom?
if </span><span>two-person carpet crew can lay 50 square feet of carpet---------- > 1 hour</span><span>
four person </span>carpet crew can lay 100 square feet of carpet---------- > 1 hour
therefore
if 100 ft² carpet----------------------- > 1 hour
222.75 ft² carpet--------------------- > x
x=222.75/100=2.2275 hours=2.23 hours
The answer is 2.23 hours
The area of the circle is 0.5.
