6 0

Answer:

12 months in a year

6 is half a month so we're going off of 6 months.

So:

821*0.15= 123.15

821- 123.15= 697.85

697.85*0.15= 104.6775

697.85-104.6775= 593.1725

593.1725*0.15= 88.975875

593.1725-88.975875= 504.196625

504.196625 *0.15= 75.62949375

504.196625- 75.62949375= 428.56713125

428.56713125*0.15= 64.2850696875

428.56713125-64.2850696875 = 364.282061562

364.282061562*0.15= 54.6423092344

364.282061562-54.6423092344 = 309.639752328

So its 310 fish.

A right rectangular prism has base dimensions of 3 inches by 12 inches and a height of 5 inches. An oblique rectangular prism ha
KonstantinChe [14]
Yes they are. Given that a volume of a rectangular prism is V=l•w•h, we can plug them into an equation and compare them. I'll call the Right rectangular prism figure R and the oblique rectangular prism O


For Figure R, We know all the basic needs to find the volume. This means we can plug it in.

V=l•w•h
V=12•3•5
Now We can solve for V
V=12•15
V=180

The volume of the right rectangular prism is 180in^3


Now, For figure O.
V=9•4•5
V=9•20
V= 180.


With this in mind, We now can say that the volumes of both the rectangular prisms are the same.

A ladder is placed 10 feet away from a tree. The length of the ladder is 25 feet. Find the height of the tree?
Dimas [21]

Answer:

23ft approx

Step-by-step explanation:

Given data

Distance from tree= 10ft

Length of ladder= 25ft

We can find the height of the tree by applying the Pythagoras theorem

z^2= x^2+y^2

z= The height of the ladder

x= The distance from the tree

y= The height of the tree

25^2= 10^2+ y^2

625=100+y^2

625-100=y^2

525=y^2

y= √525

y= 22.91

Hence the height of the tree is 23ft approx
