The cost of the family rug with dimensions 10-ft-by-11-ft given a proportional relationship is $159.50
<h3>How to solve using ratio?</h3>
Cost = $348.00
Area of rug = length × width
= 15 ft × 16 ft
= 240 square feet
Cost of a new rug = x
Area = length × width
= 10 ft × 11 ft
= 110 square feet
- Equate the ratio of cost to area of both rugs
348 : 240 = x : 110
348/240 = x/110
cross product
348 × 110 = 240 × x
38,280 = 240x
x = 38,280 / 240
x = $159.50

Answer:
10.5 square units
Step-by-step explanation:
3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put
0.6
x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]
I'm sorry if it was confusing, I hope it helped!
Nicky's plan can be made into this equation y=25+0.15x
Mickey's plan can be made into this equation y=40+0.10x
to make y equal you have to solve out 25+0.15x=40+0.10x you can solve this further into .05x=15 and then into x=300.
Answer:
True
Step-by-step explanation:
on a number line -10 is further right than -65.
