100 POINTS PLZ HELPPP Drag each tile to the correct box. Arrange the expressions in increasing order of their estimated values.
andrew11 [14]

Answer:

<h3>\frac{\sqrt{24}- \sqrt{54} }{\sqrt{6}} = -1   </h3><h3>\sqrt{\frac{9}{20}*\frac{10\sqrt{2} }{3\sqrt{5} } = 1.4142</h3><h3>\frac{10\pi\sqrt{2}-8\pi\sqrt{2}}{2\sqrt{2}}  = π =3.14159</h3><h3>\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}} = π² = 9.8696</h3>

Explanation:

1.) Rewrite √24 = \sqrt{4*6} = 2\sqrt{6}   Rewrite √54 =\sqrt{9*6}= 3\sqrt{6}

Divide both terms by the denominator; √6 cancels. 2-3 = -1

2.) Rewrite as \frac{3}{2\sqrt{5}} ×\frac{10\sqrt{2}}{3\sqrt{5}}  The 3's cancel.  10/2 = 5√2 in the numerator.

√5 × √5 = 5 in the denominator.  The 5's cancel.

That leaves √2 ≈1.4142

3.) Divide the terms in the numerator by the term in the denominator.

√2's cancel.  10π/2 = 5π   8π/2 = 4π  

Subtract and we are left with π = 3.14159

4.) \pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}  The square roots are reciprocals. They multiply to 1

We are left with π × π = π² ≈  9.8696

What is the distance between the penguins and the fish tanks?
astraxan [27]

Answer:

the distance between the penguins and the fish tanks is 81 ft

Step-by-step explanation:

Let A is the point of whales

Let B is the point of Sharks

Let D is the point of Dophines

Let P is the point of penguins

Let F is the point of Fish tank

From a look at the photo, we can find some special properties that:

AB//PF

In triangle ABD and DPF we have

  • ∠BAD=∠PFD(Alternate angles)
  • ∠ADB=∠PDF(Vertically opposite angles)

By AA rule, ABD and DPF are similar to each other

Therefore, using the similarity property, we have:

\frac{AD}{DF} = \frac{AB}{PF}

\frac{30}{45}=\frac{54}{x}\\x=\frac{54{\times}45}{30}\\x=81feet

So the distance between the penguins and the fish tanks is 81 ft
