These equations calculate kinetic energy and gravitation potential energy.

Kinetic energy (KE) is the energy an object has because of its motion. That’s why it’s calculated using its mass and speed.

Gravitational potential energy (CPE) is the energy an object has due to its position in the gravitational field. This is the energy that can be converted by dropping it or letting it fall which is why the gravitational constant and height as well as mass are needed.

If you have any equations needed to be calculated, I’d be happy to help.

A company making backpacks charges $29.99 for each backpack. It costs $6.45 to make each backpack. The company can make backpack
Ne4ueva [31]

A minimum of 220 backpacks must be produced to obtain the desired benefits.

Since a company making backpacks charges $ 29.99 for each backpack, and it costs $ 6.45 to make each backpack, and the company can make backpacks in multiples of 10 and there is $ 1,000 in fixed costs, and the company wants to make at least $ 4,000 profit each week, to determine how many backpacks should be produced, the following calculation must be performed:

  • 29.99 - 6.45 = 23.54
  • 500 x 23.54 - 1000 = 10,770
  • 250 x 23.54 - 1000 = 4.885
  • 220 x 23.54 - 1000 = 4,178.80
  • 210 x 23.54 - 1000 = 3,943.40

Therefore, a minimum of 220 backpacks must be produced to obtain the desired benefits.

In a regular triangle ABC with side 1, two squares MNKL, RKPT are drawn such that points M, L, R are on the side AC (the order o
Orlov [11]

Answer:

  • MN = (21 -6√3)/37 ≈ 0.286694
  • RK = (14√3 -12)/37 ≈ 0.331046

Step-by-step explanation:

In the attached figure, we have defined LM to be length x. Then the other lengths on side AC are ...

  AM = LR = x/√3

  RC = (2/√3)RK = (2/√3)(2/√3)x = 4/3x

Then the sum of lengths along AC is ...

  AC = AM +ML +LR +RC

  1 = x(1/√3 +1 +1/√3 +4/3) = x(7/3 +2/√3) = x(7√3 +6)/(3√3)

Then the value of x is ...

  x=\dfrac{3\sqrt{3}}{7\sqrt{3}+6}=\dfrac{3\sqrt{3}(7\sqrt{3}-6)}{(7\sqrt{3})^2-6^2}=\dfrac{3(21-6\sqrt{3})}{3(49-12)}\\\\\boxed{MN=\dfrac{21-6\sqrt{3}}{37}}\\\\RK=\dfrac{2\sqrt{3}}{3}MN\\\\\boxed{RK=\dfrac{14\sqrt{3}-12}{37}}

Which expression is equivalent to 9x - 4 + 4x + 5x + 19
dexar [7]

Answer:

18x + 15

Step-by-step explanation:

Combine like terms & simplify the given expression:

9x - 4 + 4x + 5x + 19

(9x + 4x + 5x) - 4 + 19

(13x + 5x) + (19 - 4)

(18x) + 15

18x + 15 is your answer.

Volume=<br> A) 91 2/3 pie cubic units <br> B) 275 pie cubic units <br> C) 36 2/3 pie cubic units
MrMuchimi

the volume is 1/3 * height *area of the base (the circle) in cubic units

the area of the circle is pi*r²

wich gives us

1/3 * 11 * pi * 5²

rearrange

= 5² * 11 * 1/3 * pi

= 25*11*1/3*pi

= 275*1/3*pi

= 275/3 *pi

= (91 2/3)*pi

in cubic units

so your answer is the first option
