9. Find the dimensions of the<br>4 triangular faces of the pyramid.<br>(Height is 55.5 ft)<br>

Minchanka [31]

Answer:

$Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\$

Step-by-step explanation:

We have a 4-sided triangular pyramid , where

$Q=\frac{\pi}{2}*H\\P=Q*\sqrt{\frac{1}{2}+\frac{4}{\pi ^{2}}}\\Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\$

Answer:

0.3 galloons of water.

Step-by-step explanation:

We know that 1/5 galloons of water fills 2/3 of the bin.

So, we can write the following fraction:

$\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}$

We want to find how many galloons will fill the entire bin or 1 whole bin. So, we can write the following proportion:

$\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}=\frac{x\text{ galloons}}{1\text{ bin}}$

To find our answer, we need to solve for x.

So, let's cross-multiply. This yields:

$\frac{2}{3}x=\frac{1}{5}$

Multiply both sides by 3:

$3(\frac{2}{3}x)=3(\frac{1}{5})$

The left side simplifies. Multiply on the right:

$2x=\frac{3}{5}$

Now, multiply both sides by 1/2:

$\frac{1}{2}(2x)=\frac{1}{2}(\frac{3}{5})$

Simplify the left. Multiply on the right:

$x=\frac{3}{10}$

So, 3/10 of 0.3 of a gallon of water will fill the entire bin.

And we're done!

You are standing at point C, 45 feet from the Point State Park fountain in Pittsburgh, PA. The distance from you to a point of t

bearhunter [10]

The tangent line DC is perpendicular to the radius of the park

The length of AC is 245 feet

<h3>How to determine the distance AC?</h3>

To calculate the distance AC, we start by calculating the length of AB using:

DC^2 = (BC + AB) * BC

So, we have:

105^2 = (45 + AB) * 45

Evaluate the exponent

11025 = (45 + AB) * 45

Divide both sides by 45

245 = 45 + AB

Rewrite as:

AB + 45 = 245

From the figure, we have:

AC = AB + 45

Substitute AB + 45 = 245

AC = 245

Hence, the length of AC is 245 feet
