Answer:

Step-by-step explanation:
Dario purchased a party size sub, and he decides to share it with 3 of his friends. So, he cuts the sub into 4 equal pieces. However, another one of his friends also showed up, and there are now 5 people in total
Part A
Now that the sub will be shared equally among 5 people, will each person get more or less sub? Briefly state why you think so.
The amount that each person would get after the sub is divided in 5 people equally is lesser than the amount of sub that they were getting when there were 4 people.
How to interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b = a[/tex] divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )
Firstly the sub was divided in 4 parts,
and when 5 people came, so it was decided to share the sub in 5 equal parts.
The more we increase the number in which the considered thing (here sub) is to be divided, the lesser each part would be.
Let the sub is measured as 'a' units.
Case 1: Previously when 4 people were there:Each person would get: [tex]\dfrac{a}{4}[/tex]
Case 2: When there got 5 people:Each person would get: [tex]\dfrac{a}{5}[/tex]
We know that:
[tex]4 < 5[/tex]
Multiply both the sides by 'a', assuming 'a' is positive, we get:
[tex]4a < 5a[/tex]
Divide both the sides by 20:
[tex]\dfrac{4a}{20} < \dfrac{5a}{20}\\\\\dfrac{a}{5} < \dfrac{a}{4}[/tex]
Thus, the amount that each person would get after the sub is divided in 5 people equally is lesser than the amount of sub that they were getting when there were 4 people.

Now, how to solve fraction problems using reciprocals?
We use reciprocals when dividing fractions.What is a Reciprocal?
It's simply a number flopped over (like 1/4 is the reciprocal of 4 (4/1)How to Divide Fractions?
Simply multiply the first fraction times the reciprocal of the second one.Basically, dividing by 1/2 is the same as multiplying times 2 (or 2/1, which is the exact same thing)

what is the radius of the cone
Answer:
Step-by-step explanation:
You can use calculus to derive the equation for the volume of a cone.
if we take an circle at the tip of the cone the radius is 0 but what we want to do is integrate along the x axis from 0 up to the height of the cone H.
So, the equation becomes
[tex]\int\limits^H_0 {\pi r^{2} } \, dx[/tex]
r is related to x by the formula for a line; r = m*x+b
m is the rise over the run which is given by the maximum height H divided by the maximum radius R. So m = H/R and the intercept b = 0
now we have a formula for r in terms of x and with a little variable manipulation we can get a formula for x in terms of r
r = (R/H)*x
If we replace r by this formula in our integral we get:
[tex]\int\limits^H_0 {\pi ((R/H)*x)^{2} } \, dx[/tex]
since [tex]\pi[/tex], R, and H are constants we can move them outside the integral:
[tex]\pi (R^{2} /H^{2} )*\int\limits^H_0 {x^{2} } \, dx[/tex]
the integral is easy. It is [tex]\frac{x^{3}}{3}\left \{{{x=H}\atop{x=0}} \right.[/tex] which is equal to [tex]H^{3} /3[/tex]
substituting back into the original formula we get the equation for the volume of a cone.
V = [tex](\pi R^{2}H)/3[/tex]
Use this formula with the values given in the question to solve for R.
183.17 = [tex]\pi[/tex][tex]R^{2}[/tex]*7/3
rearranging we get
[tex]\sqrt{183.17*3/(7\pi ) }[/tex] = R
R ≅ 5

At a restaurant, Trevor decides to tip the server 16% of the bill. If he leaves a $4.00 tip, which proportion could be used to find how much the bill was for?
16/100 = x/4
16/100 = 4/x
4/100 = x/16
4/100 = 16/x
The answer is: 16/100 =4/x
16 divided by 100 is 0.16
And 4x4 is 16
x is the varible of how much so it goes 4/x
So your answer is 16/100 =4/x
