10-x=C=2πr

(10-x)/(2π)=r

A=π(100-20x+x^2)/(4π^2)

A=(x^2-20x+100)/(4π)

...

x/4=s, x=4s  using this in the area of a circle we get:

A=(16s^2-80s+100)/(4π)

A=(4s^2-20s+25)/π

And of course the area of a square is s^2

A=(4s^2+πs^2-20s+25)/π

Together, two apples have 175 gram of fat. How many apples have a total of 4 grams of fat?
inysia [295]

I'm pretty sure if the answer accepts decimals, if two apples = 175 grams, then one apple equals 87.5 grams, and if we want an apple that equals four grams, it would be less than one apple so we would divide the grams of one apple till it equals 4, therefore 87.5/4 = 21.875

P.S. im not entirely sure this is right im just trying to help :)

Leilani is a member of her schools for person 1600 Meter relay team in each really Lelani runs 1/4 of the 1600 meter relay team
taurus [48]

Answer:

She ran a total distance of 8,800m or 8.8km

Step-by-step explanation:

In this question, we are asked to calculate the total distance ran by Leilani if at each meet she runs a distance that is exactly equal to a quarter of the total and she competed 22 times during the year.

Firstly, we proceed to calculate the the distance she runs at each relay for her team. We were told she runs a distance equivalent to a quarter.

Mathematically, the distance she runs will be ; 1/4 * 1,600 = a distance of 400 meters

Now, we are told that she ran at 22 different track meets last year. So the total distance she ran will be 22 * 400 = 8,800m or 8.8km

DedPeter [7]

Answer: 32/24

Step-by-step explanation:

On a field trip, there are 8 adults and 24 students. What is the ratio of students to the total number of people on the field trip?

32 is the total amount of people on the field trip, 24 students

32/24 would be the correct ratio.

mr. bob is very good friends with Mr. jeff and likes to rearrange Mr. jeff's classroom desks around. The coefficient of kinetic
Brrunno [24]

The net force in the forward direction will be 9 Newton.

<h3>What is a expression? What is a mathematical equation? What is friction? What is coefficient of kinetic and static friction?</h3>
  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
  • Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
  • The opposing force between two objects in contact that are moving against each other is called kinetic friction. The force that has to be overcome in order to get something to move is called static friction.
  • F(Kinetic) = μ[k]N and F(static) = μ[S]N

We have the coefficient of kinetic friction between the plastic legs of the desks and the tile is 0.3. The desks have a mass of 17 kg each. Mr. bob applies of a force of 60 N to the desk

We can write the equation for the net forward motion as -

F{net} = F{applied} - F{friction}

F{net} = F{applied}  - μ[k]N

F{net} = F{applied} - μ[k]mg

F{net} = 60 - 0.3 x 17 x 10

F{net} = 60 - 51

F{net} = 9 Newton

Therefore, the net force in the forward direction will be 9 Newton.
