What does 5/15 equal

harina [27]

Because 5/15 is not a simplified fraction, seeing that its numerator and denominator both have a common factor, you can simplify it to find an equivalent fraction. To do this, divide 5 from the numerator and denominator and then you would get a result of 1/3.

The Greek method for finding the equation of the tangent line to a circle uses the fact that at any point on the circle the line

Alina [70]

Answer:

Step-by-step explanation:

Given circle has equation as

$x^2+y^2 =49$

Center = P(0,0)

The point of contact of tangent = $(1,4\sqrt{3} )$ Q

Since tangent is perpendicular to the radius at the point of contact, we have

Slope = $\frac{4\sqrt{3} }{1}$ as slope of perpendicular to tangent

So tangent slope would be

-1/slope of this line

= $\frac{-1}{4\sqrt{3} }$

We have point on this line as given point

So using point slope form equation of tangent is

$y-4\sqrt{3} =\frac{-1}{4\sqrt{3} } (x-1)\\4\sqrt{3} y -48 =-x+1\\x+4\sqrt{3} y= 49$

How do you do this with decimals

ICE Princess25 [194]

Answer: x=102

Steps:

This is an isosceles triangle which mean 2 angles and 2 sides are congruent. In this case, the 3.3 sides corresponds to the 39 degree angle. This means that the other angle next to x angle is also 39 degrees.

39+39= 78

All the angles in the triangle needs to equal 180.

So subtract 78 from 180 to find the degree of x angle.

180-78= 102

What is 60% of 250?????

Ray Of Light [21]

Well, what you would do is 60% of 150, you'd change the if to a multiplication sign. 60/100x150/1. then follow the photo. I THINK!!
