If y varies inversely with x and y=2 when x=5, what is the value of x when y=3?
Nostrana [21]

Answer:

Step-by-step explanation:

Method

Inversely in this sentence means

y = k/x    

So you first step is to find the value of k. You do that by setting up an inverse relationship with y = 2 , x = 5

2 = k/5                     Multiply both sides by 5

2*5 = 5*k/5

10 = k

Now you are able to answer the question.

  • k = 10
  • y = 3
  • x = ?

y = 10/x

3= 10/x                      Multiply both sides by x

3*x = x * 10/x

3x = 10                      Divide both sides by 3

3x/3 = 10/3

x = 3.33 or x = 3 1/3

Answer

x = 3.33 or x = 3  1/3

Covert 12/20 to a decimal
oksano4ka [1.4K]

Answer:

.60

Step-by-step explanation:

Two points a and b are on opposite sides of a building. a surveyor selects a third point c to place transit. point c is 62 feet
lorasvet [3.4K]
Okay, so basically you are going to use the Pythagorean Theorem which states: If a right triangle has sides a and b and hypotenuse c then a2+b2=c2.
You already have the distance between AC and BC so you want to figure out the distance between AB. All you have to do is plug in the information. If you draw out a picture, it will help you to visualize it. 
I believe the answer is 26...
