Hi

Let's call X  the amount in the beginning.  

we  have X*1.03^6 = 1819.77

                X =  1819.77 /  1.03^6

                X ≈ 1524.03

The main show tank has a radius of 70 feet and forms a quarter sphere what is the volume of the quarter sphere shaped tank?
Usimov [2.4K]

Answer:

359333.33\textrm{ }ft^{3}

Step-by-step explanation:

Given:

Radius of spherical tank, r=70\textrm{ ft}

Volume of a quarter of a sphere is given as:

V=\frac{1}{3}\pi r^{3}

Plug in 70 ft for r, \frac{22}{7} for \pi and solve for the volume, V. This gives,

V=\frac{1}{3}\pi r^{3}\\\\ V=\frac{1}{3}\times \frac{22}{7}\times (70)^{3}\\\\ V=359333.33\textrm{ }ft^{3}

Therefore, the volume of the quarter sphere shaped tank is 359333.33\textrm{ }ft^{3}

If alvin sold 60% of his baseball cards, gave away 30% of those that were left, and still had 40 baseball cards in his possessio
kipiarov [429]

Answer:

The number of baseball card to begin with is 143

Step-by-step explanation:

Let The number of baseball cards = x

The number of sold baseball card = 60% of x

                                                         = 0.6 x

The number of left baseball card = x - 0.6 x = 0.4 x

The number of card gave away = 30 % of left cards

                                                     = 0.3 × 0.4 x = 0.12 x

The number of card left in his possession = 40

So, 0.6 x + 0.12 x + 40 = x

Or,  40 = x - 0.6 x - 0.12 x

Or,  40 = 0.28 x

∴   x = \frac{40}{0.28}  =  142.85 ≈ 143

Hence The number of baseball card to begin with is 143  Answer

  • Answer:

<em>= 26,(6)</em>

<em>≈ 26,7</em>

  • Step-by-step explanation:

<em>C = 5/9(F - 32)</em>

<em>= 5/9(80 - 32)</em>

<em>= 5/9(48)</em>

<em>= 5×48/9</em>

<em>= 240/9</em>

<em>= 26,(6)</em>
