Law Incorporation [45]3 years ago

Answer: 346.4

Step-by-step explanation:

The whole triangle ABD is a 30-60-90 right triangle. In 30-60-90 triangles, the smallest side is x, the middle side is x\sqrt{3}, and the largest side/hypotenuse is 2x.

Side AB is the smallest side and therefore x=300. Side BD is the middle side and so we can use x\sqrt{3} and we get BD=300\sqrt{3}=519.615

The question is asking for CD, and we know that CD can be equal to BD minus BC since that would isolate CD

Triangle ABC is also a 30-60-90 triangle but the 300 feet is the middle side in this triangle. So we can do 300=x\sqrt{3} and divide 300 by radical 3 and get that x=173.205

Side BC is the smallest side of this triangle so it would be x and x is 173.205.

Now that we have the whole side BD and the part of it BC. We can subtract BD by BC (519.615-173.205) and we get that CD=346.4

a raised rectangular garden is two feet more than three times as long as it is wide. the depth of the pool is half the width. if
stepladder [879]

Answer:

49.5ft³

Step-by-step explanation:

If it is 2 ft more than 3 times as long as it is wide then:

l = 3w + 2

which means:

w = (l-2)/3

and:

d = 1/2((l-2)/3)

Now just substitute in 11 for l

w = (11 - 2)/3

w = 9/3

w = 3

d = 1/2((11-2)/3)

d = 1/2(9/3)

d = 1/2(3)

d = 1.5

So the total volume is:

11 * 3 * 1.5

49.5

Vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his
liberstina [14]

Step-by-step explanation:

<em>Vamsi is X years old</em>

Vamsi = X

<em>his brother is 3 years elder to him</em>

Brother = X + 3

<em>his uncle is 4 times his age</em>

Uncle = 4X

<em>his aunt is 5 years younger than his uncle</em>

Aunt = Uncle - 5

<em>what will be the age of his uncle 6 years from now</em>

= 4X + 6

<em>what are the ages of vamis brother, uncle and aunt?</em>

Assume Vamis = 15 years

Brother = X + 3 = 15 +  3 = 18

Uncle = 4X = 4 * 15 = 60

Aunt = Uncle - 5 = 60 - 5 = 55

<em>what will be the age of his uncle 6 years from now</em>

Uncle = 4X + 6 = 60 + 6 = 66
