-5/8
.....................
Answer:
<em>C. -4.01</em>
<em>H. -7</em>
Step-by-step explanation:
<u>Solving inequalities:</u>
We have a set of numbers to verify which ones of them make the below inequality true
Rearrange
Operating
Flipping
The set of solutions contains every number less than -4
There are only two numbers less than -4 in the set of options:
C. -4.01
H. -7
The answer is C (^‿^✿)
All you have to do is subtract 154.50 by 65.50 and add that answer to 275.25
Your answer is the second option, she should choose the rectangular tiles because the total cost will be $8 less.
To find this answer we need to first find the total cost for using square tiles, and the cost for using rectangular tiles, and compare them. We can do this by finding the area of each tile individually, calculating how many tiles we would need, and multiplying this by the cost for one tile:
Square tiles:
The area of one square tile is 1/2 × 1/2 = 1/4 ft. Therefore we need 40 ÷ 1/4 = 160 tiles. If each tile costs $0.45, this means the total cost will be $0.45 × 160 = $72
Rectangular tiles:
The area of one rectangular tile is 2 × 1/4 = 2/4 = 1/2 ft. Thus we need 40 ÷ 1/2 = 80 tiles. Each tile costs $0.80, so the total cost will be 80 × $0.80 = $64.
This shows us that the rectangular tiles will be cheaper by $8.
I hope this helps! Let me know if you have any questions :)
