Answer:

400

Step-by-step explanation:

In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.

48÷0.12 or 48/0.12 = 400

What expression is equivalent to? Screenshots attached. Please help!
Galina-37 [17]

Answer:

the correct option is C i.e. 8x^4yz^4\sqrt{2yz}

Step-by-step explanation:

We need to solve the expression :

\sqrt{128x^8y^3z^9}

Factors of 128 are: 2x2x2x2x2x2x2

and we know √ = 1/2

and √a.b = √a.√b

Solving:

=\sqrt{128x^8y^3z^9}\\\\=\sqrt{128} \sqrt{x^8} \sqrt{y^3} \sqrt{z^9}\\=\sqrt{2x2x2x2x2x2x2}\sqrt{x^8} \sqrt{y^2.y} \sqrt{z^8.z}\\=\sqrt{2^2x2^2x2^2x2}\sqrt{x^8} \sqrt{y^2.y} \sqrt{z^8.z}\\=(2^2)^{1/2} (2^2)^{1/2}(2^2)^{1/2} (2)^{1/2} (x^8)^{1/2} (y^2)^{1/2} (y)^{1/2} (z^8)^{1/2} z^{1/2}\\=2.2.2.(2)^{1/2}x^4y(y)^{1/2}z^4(z)^{1/2}\\=8x^4yz^4\sqrt{2yz}

So, the correct option is C i.e. 8x^4yz^4\sqrt{2yz}

Answer:

  4 : 3

Step-by-step explanation:

The ratio of numbers of students is ...

  hot dog : hamburger = 16 : 12 = 4 : 3

__

To reduce the ratio to lowest terms, remove the common factor of 4 from each number. 16 = 4·4; 12 = 4·3.
