<h2>Explanation</h2>First, we are going to use the law of fractional exponents:
We can infer form our expression that and
, so let's replace the values:
Notice that we can also decompose 16 into prime factors to get , so we can rewrite our expression as follows:
Finally, we can use the rule of radicals: , so:
Answer:
Step-by-step explanation:
The can in this problem has a cylindrical shape. The volume of a cylinder can be calculated with the following formula:
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem we have:
h = 96 mm is the height of the can
d = 66 mm is the diameter of the can
So the radius of its base is
And therefore, the volume of the can is:
Answer:
Step-by-step explanation:
c + a = 342 ..................... <em>(1)</em>
5c + 12a = 2550 ........... <em>(2)</em>
- 5 × <em>(1)</em> + <em>(2)</em>
7a = 840
<em>a = 120</em>
<em>c</em> = 342 - 120 <em>= 222</em>
