Answer:

A triangle with angles:

"45°, 45°, 90°"

Is a triangle rectangle, with two catheti of equal length.

Now, there is a lot of problems that you can solve with this:

"Suppose that you want to find the height at which you need to attach a wire in a tree, such that the distance between the tree and the ground is 18ft, and the distance between the base of the tree and the two points where the wire is fixed is exactly the same"

Well, here we have a triangle rectangle with a hypotenuse of 18 ft, with cathetus of equal length (the catheti are the tree and the distance between the base of the tree and the point where the wire is attached at the ground)

And because the catheti are equal, then the angles are 45°, 45° and 90°.

What is the first step in the constitution of a line perpendicular to AB and passing through an external point M?
NikAS [45]

take your compass on a point on your line. then draw a circle. take the 2 points in which the circle hit the line and draw 2 circles larger than half the distance between he 2 points. take the point that they intersect and and connect it to the line and you point M and it is purpendicular. does that make sense?

If f(x) =3/2x +14 then find the value of f(0)
Neko [114]

Answer:

14

Step-by-step explanation:

Replace each instance of x with 0 to find f(0):

f(0) = (3/2)(0) + 14 = 14

Johanna, Elizabeth, and Dan are preparing a chemical solution for a research project. When
Bond [772]

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given by:

  • Johanna's: 1/6.
  • Elizabeth's: 1/6.
  • Dan's: 1/4.

Hence the together rate is given by:

\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}

\frac{1}{x} = \frac{1}{3} + \frac{1}{4}

\frac{1}{x} = \frac{4 + 3}{12}

7x = 12

x = 12/7

x = 1.71.

They would prepare the solution in 1.71 minutes working together.
