Nady [450]

Answer:

  • Option A. $140.00

Explanation:

<u>1. Using the minimun number of sheets  of paper in the interval [300, 400]</u>

a) Cost: $ 2.00 / 100 sheets

b) 300 sheets / day × $ 2.00 / 100 sheets = $ 6.00 / day

c) Approimately 20 school days per month:

  • $ 6.00 / day × 20 day = $ 120.00

<u>2. Using the maximum number of sheets of paper in the interval [300, 400]</u>

a) Cost: $ 2.00 / 100 sheets

b) 400 sheets / day × $ 2.00 / 100 sheets = $ 8.00 / day

c) Approimately 20 school days per month:

  • $8.00 / day × 20 day = $ 160.00

<u>3. Middle value:</u>

Calculate the middle value between $160.00 and $120.00

  • [$120.00 + $160.00] / 2 = $140.00

Thus, the answer is the option A.

Which expression is equal to 5^4 x 5^8 ? <br><br> A: 5^12<br> B: 5^4<br> C: 5^2<br> D: 5^−4
galben [10]

Something to remember is how to multiply terms with same bases, but different exponents:

a^b \cdot a^c = a^{(b+c)}


Essentially, we add the exponents.


Using the information above, we can find our answer:

5^4 \cdot 5^8 = 5^{(4+8)} = \boxed{5^{12}}


Our answer is \boxed{5^{12}}, or A.
