Answer:
40 mm
Step-by-step explanation:
It's 40 mm because the Pythagorean Theorem explains a^2 + b^2 = c^2.
This means the unknown number plus 30^2 = 50^2
What you want to do is 50^2 - 30^2= 20^2; which would be 2500-900=1600.
You got 1600 but that isn't your final answer. You want to find the square root 1600. So 1600 square rooted is 40.
40 mm is your final answer.
Step 1: Write down the decimal<span> divided by 1, like this: </span>decimal<span> 1. Step 2: Multiply both top and bottom by 10 for every number after the </span>decimal<span> point. (For example, if there are two numbers after the </span>decimal<span> point, then use 100, if there are three then use 1000, etc.) Step 3: Simplify (or reduce) the </span>fraction<span>.</span>
Answer:
The range stays the same.
The domain stays the same.
Step-by-step explanation:
The function 
is an exponential function, where <em>a</em> is the coefficient, <em>b</em> is the base and <em>x</em> is the exponent.
The domain for this kind of functions is: All real numbers.
And the range is: (0,∞); this happen because the exponential functions are always positive when <em>a</em>>0.
Therefore, if the value of <em>a</em> is increased by 2, the domains will stay the same and the range will stay the same: (0,∞). The coefficient does not change the domain or the range if it keeps the same sign.

The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.
