You need to calculate miles per gallon.

Number of miles is just the difference in the odometer:
----> 23,927 - 23,672 = 255

Number of gallons = 16.5

MPG = 255/16.5 = 15.5

A circle is inscribed in an equilateral triangle with a side length measuring 10 mm.
Tamiku [17]
For side length s the area of the triangle is
.. A = (√3)/4*s^2
The radius of the circle will be
.. r = s/(2√3)
so the area of the circle is
.. A = π*r^2 = π*s^2/12

The fraction of the triangle that is not in the circle is
.. 1 - (π/12)/((√3)/4)
.. = 1 -π/(3√3)
.. ≈ 39.54%

Cavalieri’s principle states that if two solids of equal height have equal cross-sectional areas at every level parallel to the
Musya8 [376]

Therefore, the formula for the volume of the sphere can be derived by writing an expression that represents the volume of C. The solid between the two cones and the cylinder

<h3>What is the Volume of a Sphere?</h3>

This refers to the capacity of a sphere, which is the maximum that can be contained in the sphere. This is denoted as V=4/3πr3

Hence, we can see that based on Cavalieri’s principle that states that if two solids of equal height have equal cross-sectional areas, then the two solids have equal volume.

Therefore, the two shaded solids both have a height of 2r units, and thus, to derive the function, we would have to write an expression that represents the volume of the solids between the  two cones and the cylinder

Turn over into vertex form

  • y=-30t²+450t-790
  • y=-30(t²-15x+79/3)

Solving

  • y=-30[(t-15/2)²-359/12]

Open brackets

  • y=-30(t-15/2)²+1795/2

Accurating

  • y=-30(t-7.5)²+897..5

Compare to Vertex form y=a(x-h)²+k

Vertex

  • (h,k)=7.5,897.5

Max profit is $897.5

  • ticket price should be $7.5
