A number to the 12th power divided by the same number to the 9th power equals 125 what is the number

nadezda [96]

If x to the 12th power is divided by x to the 9th power:

Since they share same bases, and are being divided, it would be the same as x^{12 - 9), or x^{3}

Now, simply find the cube root of 125, which is 5.

Therefore, the number (x) must be equal to 5.

Hope this helps! :)

emmainna [20.7K]

Answer:

1 adult cat

Step-by-step explanation:

Thursday:

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

$3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16$

There were 16 adult cats

Tuesday:

17 adult cats were at the pet care center.

Difference:

$17-16=1$ adult cat
