Answer:</h2>
<u><em>As a percent, the odds of having an allergic reaction would be 2%.</em></u>
This is because 1 in 50 of a chance, is equal to 1/50, and to make this a percent out of 100, just multiply both parts of the fraction by 2.
None of the choices equal 1/50, so let's just make it a percentage anyway.
1/50 ---> 0.02
0.02 ---> 2%
<em>The answer is 2%, or 1/50 as a fraction.</em>

Answer:
5 units
Step-by-step explanation;
We can use the formula for finding the length or magnitude of line joining two points.
Length = √((x2-x1)² + (y2-y1)²)
The points joining the line are C (-1,4) and D (2,0)
Length = √((2+1)² + (0-4)²)
= √((3²) + (-4)²)
= √ (9+16)
= √25
= 5 units
we know that
The volume of a cylinder is equal to
where
r is the radius of the base
h is the height of the cylinder
In this problem
For 
<u>Find the value of h</u>
<u>Find the volume of the cylinder</u>
therefore
<u>the answer is</u>
The volume of a cylinder is equal to 
Step-by-step explanation:
a = age of Alex
l = age of Lucy
m = age of Megan
a + l + m = 126
l = 3a
l = m + 7
=>
a = l/3
m = l - 7
we are using that in the first equation :
l/3 + l + l - 7 = 126
l + 3l + 3l - 21 = 378
7l = 357
l = 357/7 = 51
a = l/3 = 51/3 = 17
m = l - 7 = 51 - 7 = 44
the ratio of the age of Lucy to Alex to Megan is
51 : 17 : 44
