Answer:
c. x > 6
d. λ = 3/100
Step-by-step explanation:
c. You have the idea for the necessary equation:
speed = wavelength·frequency
The inequality is x > 6.
__
d. If λ represents the wavelength in nanometers, the range restriction can be written ...
2/100 < λ < 5/100
A possible value of λ is 3/100.

Answer:
Costco has the better deal.
Step-by-step explanation:
Find the unit rate for Costco:
<em>Remember, the unit rate is when one of the numbers in a ratio is 1.</em>
<em />
Toilet paper : Price
6 : 4.99
(divide both sides by 6)
1 : .83
<em>Remember to round to the nearest hundredth place because money only goes two places after the decimal point.</em>
<em />
Therefore, 1 roll of toilet paper at Costco costs 83 cents.
Find the unit rate for Target:
Toilet paper : Price
8 : 6.99
(divide both sides by 8)
1 : .87
Therefore, 1 roll of toilet paper at Target costs 87 cents.
Conclusion:
.83 < .87
In conclusion, Costco has a better deal because toilet paper is cheaper per roll.
