Two similar triangles have have areas of 75 m2 and 12 m2. find the ratio of the perimeters
soldi70 [24.7K]

we know that having similar triangles so the ratio of sides,area and volume are same.

s/s=s^2/s^2

we know that s^2 will be the area of triangle.

s^2/s^2=75/12

so s/s=\sqrt{75/12}

so the ratio of the perimeter of two triangles will be

(s+s+s)/(s+s+s)=(\sqrt{75} +\sqrt{75} +\sqrt{75} )/(\sqrt{12}+\sqrt{12} +\sqrt{12} )

ratio of the perimeter=\sqrt{225} /\sqrt{36}

Find the slope (3,6)<br> (3,-3) need in 5 minutes
avanturin [10]

Answer: The slope is undefined.

Step-by-step explanation:

Using the formula given, find the difference in the y coordinates of the points and divide it by the x coordinates.

(3,6)

(3,-3)  

y coordinates:  6 - (-3) =  9

x coordinates:   3- 3 = 0  

9/0 =  undefined.

Any number being divided by 0  is undefined because you can't divide something by anything.  

Also remember that if a line is vertical through any of the x coordinate, the slope will always be undefined and the equation of line is x = 3

There are 15 people on a basketball team, and the coach needs to choose 5 to put into
snow_lady [41]

Answer:

The coach can do this in 3,003 ways

Step-by-step explanation:

Here, the coach needs to select a team of 5 from a total of 15 players

Mathematically, the number of ways this can be done is simply 15 C5 ways

Generally, if we are to select a number of r items from n items, this can be done in nCr ways = n!/(n-r)!r!

Applying this to the situation on ground, we have;

15C5 = 15!/(15-5)!5! = 15!/10!5! = 3,003 ways
