Answer:

$3^2 \times 3^5 = 3^7$

3^2 * 3^5 = 3^7

Step-by-step explanation:

I assume you mean this:

$3^2 \times 3^5$

If so, then the rule is that when you multiply two numbers with the same base, you give the same base and add the exponents.

$3^2 \times 3^5 = 3^{2 + 5} = 3^7$

Multiply or divide as indicated (3x)^12/ (3x)^4

iVinArrow [24]

Answer:

$\frac{(3x)^{12} }{(3x)^{4} } =(3x)^{8}$

Step-by-step explanation:

As we are dividing by powers, we can just subtract the powers as they have the same base. As 12-4=8 the answer would be

$\frac{(3x)^{12} }{(3x)^{4} } =(3x)^{8}$

A mountain in boone county is eroding and losing elevation at a rate of 5% every millennium. if the current elevation is 1,710 m

aliina [53]

Answer: 1,393 meters tall

Step-by-step explanation:

Plug in 1710 meters for the initial amount, 0.05 for the rate of decrease, and 4 millennia for the time elapsed.

= a(1–r)t

= 1,710(1–0.05)4 Plug in values

= 1,710(0.95)4 Subtract

= 1,710(0.81450…) Simplify

= 1,392.80568… Multiply

Round to the nearest whole number.

1,392.80568… → 1,393

To the nearest whole number, the mountain will be 1,393 meters tall.

Printing machine A and printing machine B print the same newspaper printout, but machine B prints at half the rate of machine A.

klemol [59]

Answer:

The answer is below

Step-by-step explanation:

Let us assume the rate of printing in machine A is x per hour and the rate for machine B is y. Given that machine B prints at half the rate of machine A, therefore:

y = (1/2)x (1)

Also, both machine produces 200 newspaper printouts, and both operate at different times for a total of 4 hours. Therefore:

200/x + 200/y = 4 (2)

Put y = (1/2)x in equation:

$\frac{200}{x}+\frac{200}{(\frac{1}{2} )x}=4\\ \\ \frac{200}{x}+\frac{400}{x}=4\\\\Multiply\ through\ by\ x:\\\\200+400=4x\\\\4x=600\\\\x=150$

Put x = 150 in equation y:

y=(1/2)150 = 75

Therefore the rate of machine A is 150 newspapers per hour while that of machine B is 75 newspapers per hour
