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

san4es73 [151]

Answer:they would meet at 1 pm

Step-by-step explanation:

The distance between Quebec City and New York City is 520 miles.

At the point where Kate and Will meet, they would have travelled 520 miles.

Let t represent the time it takes Kate to travel a certain distance before they met.

Distance = speed × time

If Kate drives at 55mph, the distance covered would be

55 × t = 55t.will drives at 75 mph

Since Will left same that that Kate left, distance travelled by Will in t hours would be

75 × t = 75t

Since the total distance covered is 520 miles, it means that

55t +75t = 520

130t = 520

t = 520/130 = 4

9 am + 4 hours = 1 pm
