Step-by-step explanation:

you would multiply the radius times pi (you would get 6.42 ft) and then divide that by 1.35 (simplifying it to 642 divided by 135 and you would then get 4.706...)which rounds to the answer

Show that a^12 can be written as a perfect square and a perfect cube

Elden [556K]

Answer:

Step-by-step explanation:

Doing this the long way, write a^12 as a product of "a"s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

Now group them into groups of 4

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube

Now do the same thing with groups of 6s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

a^12 = (a^6)^2

So the two answers are

Perfect cube: [(a^4)]^3

Perfect square: (a^6)^2

patriot [66]

Given:

There are between 24 and 40 students in a class.

The ratio of boys to girls is 4:7

To find:

The number of students in the class.

Solution:

Let the number of boys are girls are 4x and 7x respectively, where, x must be a positive integer because number of boys and girls is always a positive integer. Then, the total number of students is

$\text{Total students}=4x+7x$

$\text{Total students}=11x$

It means total number of students is multiply of 11.

Multiples of 11 are 11, 22, 33, 44, ... . So, multiples of 11 between 24 and 40 is 33.

Therefore, the total number of students in the class is 33.
