To find the value of a variance add and subtract the variance from the original number.
The original number is 32 hot dogs.
The variance is 5 hot dogs.
32-5 = 27
32 + 5 = 37
This means he needs to eat between 27 and 37 hot dogs.
he inequality with variance is written as: 27 < h < 37
The price in dollars per gallon is 4.02 dollars per gallons.
<h3>How to find the price of gasoline in dollars per gallon?</h3>
Gasoline costs 1.05 euro per litre in France.
The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.
Then, equate it the quantity of litres to gallons.
Hence,
1 euro = 1.01 dollars
1.05 euro = ?
cross multiply
price = 1.05 × 1.01
price = 1.0605 dollars
1 litres = 0.264172 gallons
Therefore,
cost = 1.0605 / 0.264172
cost = 4.01552442257 dollars per gallons
cost = 4.02 dollars per gallons
Therefore, the price in dollars per gallon is 4.02 dollars per gallons.

Step-by-step explanation:
let the angle be x
20+4x+x=180
20+5x=180
5x=160
x=32
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.
