79
Step-by-step explanation:
The difference between 79 and 22 is 57. 79 is THE number. All you have to do is add 22 and 57 because the answer you get would ALWAYS have one of the numbers added as the difference.
Answer:
The number of hamburgers is 109.
Step-by-step explanation:
Let h = number of hamburgers
Let c = number of cheeseburgers
The total number sold gives us the equation below.
h + c = 327
"The number of cheeseburgers sold was two times the number of hamburgers sold.
This gives us the equation
c = 2h
Now we substitute c with 2h in the first equation and solve for h.
h + 2h = 327
3h = 327
h = 109
The number of hamburgers is 109.
Ending Amount = Beginning Amount / 2^n
where "n" is the number of half-lives
n = 139 / 27.8 = 5 half-lives
Ending Amount = 7.6 oz / 2^5
Ending Amount = 7.6 oz / 32
Ending Amount = .2375 ounces

Answer:
V = 277.088 m³
Step-by-step explanation:
Volume of Cylinder Formula: V = πr²h
We are given <em>r</em> = 4.2 and <em>h</em> = 5, so simply plug it into the formula and solve:
V = π(4.2)²(5)
V = 17.64π(5)
V = 88.2π
V = 277.088
First, take 2.2 and subtract it from 8.5. You get 6.3. Split that by three parts, and it's 2.1. Now add that to the 2.2. You get 4.3
So, the answer: 4.3
God bless!
