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

Answer:

Cost of car including VAT = $17,700

Step-by-step explanation:

Given:

Cost of car without VAT = $15,000

Rate of VAT = 18%

Find:

Cost of car including VAT

Computation:

Cost of VAT = Cost of car without VAT x Rate of VAT

Cost of VAT = 15,000 x 18%

Cost of VAT = 15,000 x 18

Cost of VAT = $2,700

Cost of car including VAT = Cost of car without VAT + Cost of VAT

Cost of car including VAT = 15.000 + 2700

Cost of car including VAT = $17,700

(1/27)^x-6=27 Could I please have a step by step as well? Much appreciated!

Answer:

$x = 7$

Step-by-step explanation:

1) Use Division Distributive Property: (x/y)^a = x^a/y^a.

$\frac{1}{ {27}^{x - 8} } = 27$

2) Multiply both sides by 27^x - 8.

$1 = {27} \times 27^{1 + x - 8}$

3) Use the product rule: x^a x^b = x^a+b.

$1 = {27}^{1 + x - 8}$

4) Simplify 1 + x - 8 to x - 7.

$1 = {27}^{x - 7}$

5) Use Definition of Common Logarithm: b^a = x if and only if logb (x) = a.

$log_{27}1 = x - 7$

6) Use Change of Base Rule.

$\frac{ log_1 }{ log{27} } = x - 7$

7) Use rule of 1: log 1 = 0.

$\frac{0}{ log_{27}} = x - 7$

8) Simplify 0/log_27 to 0.

$0 = x - 7$

9) Add 7 to both sides.

$7 = x$

10) Switch sides.

$x = 7$

Therefor, the answer is x = 7.
