Answer:

John read for 3 hours

Step-by-step explanation:

Mike read 6 hours. Sasha doubled the reading time so 3*2=12. Tom read half of that time, so it is the same as Mike which is 3. John read half of Tom's time, so 6 divided by 2 is 3.

What is the factorization of 216x12 – 64?
GalinKa [24]

9514 1404 393

Answer:

  (c)  (6x^4 – 4)(36x^8 + 24x^4 + 16)

Step-by-step explanation:

The correct factoring can be found by looking at the first exponent in the second set of parentheses.

The factorization of ...

  (a^3 -b^3)

is ...

  (a -b)(a^2 +ab +b^2)

__

Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...

  a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

If 100 pencils can be sold for $90, then how many pencils are needed to earn $8500?
ira [324]

Step-by-step explanation:

You can set up a proportion.

Let x be the number of pencils needed.

\frac{100}{90} = \frac{x}{8500}

Solve for x.

x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)
