Answer:

55 paper plates for $4.40 is your best buy because the price for unit is $0.08

Step-by-step explanation:

First find the price for unit of each option

we have :

85 paper plates for $8.08

55 paper plates for $4.40

To find the price per unit we divide  8.08 ÷85 = .09 rounded to the nearest cent  is .10

and 4.40 ÷ 55 = .08

Therefore, the best buy is $.08  or 55 paper plates for $4.40

mars1129 [50]

Answer:

  t=5.0days

Step-by-step explanation:

Using the formula for the exponential decay that is N=N_{0}e^{-kt}, we have N=\frac{1}{2}{\times}46=23, N_{0}=46 and k=0.1374.

Thus, N=N_{0}e^{-kt} becomes

23=46{\times}e^{-0.1374t}

\frac{23}{46}=e^{-0.1374t}

\frac{1}{2}=e^{-0.1374t}

Taking log on both sides, we get

ln(\frac{1}{2})={-0.1374t}

t=\frac{ln\frac{1}{2}}{-0.1}

t=\frac{-0.6931}{-0.1374}

t=5.0days

Question 1 (1 point)
Natalija [7]

Answer: OPTION B.

Step-by-step explanation:

Given the equation 48=-8(\frac{3b}{4}+2) you can find an equivalent equation by simplifying it.

You need to remember the multiplication of signs:

(-)(-)=+\\(+)(+)=+\\(+)(-)=-

Now you can apply the Distributive property:

48=\frac{(-8)(3b)}{4}+(-8)(2)\\\\48=\frac{-24b}{4}-16

Simplifying the equation, you get:

48=-6b-16

You can observe that this equivalent equation matches with the equation provided in option B.
