Answer:

With probability you can multiply your chances in this case.

Getting an odd number: 1/2

Getting a number greater than 4: 1/6

Therefore it is a 1/12 chance to be both odd and greater than 4

The length of ZX is 2 units. What is the perimeter of triangle XYZ?

dezoksy [38]

Keywords

triangle,perimeter,distance, length, side, points

we know that

The perimeter of a triangle is the sum of the three length side

To find the length side calculate the distance between two points

The formula to calculate the distance between to points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

Step 1

Find the distance ZY

$Z(1,0)\\Y(3,1)$

substitute the values

$d=\sqrt{(1-0)^{2}+(3-1)^{2}}$

$dZY=\sqrt{5}\ units$

Step 2

Find the distance XY

$X(-1,4)\\Y(3,1)$

substitute the values

$d=\sqrt{(1-4)^{2}+(3+1)^{2}}$

$dXY=\sqrt{25}=5\ units$

Step 3

Find the perimeter of the triangle

$P=ZX+ZY+XY$

we have

$dZX=2\sqrt{5}\ units$

$dZY=\sqrt{5}\ units$

$dXY=5\ units$

Substitute

$P=(2\sqrt{5}+\sqrt{5}+5)\ units$

therefore

the answer is

$P=(3\sqrt{5}+5)\ units$

What are different solutions of 1x +2y = 12

miv72 [106K]

Answer:

x=12, y=6

Step-by-step explanation:

Very simple!

Just substitute 0 for y and solve for x!

$x+2(0)=12$ (anything times 0 equals 0!)

$x=12$

Now you can do the same thing but substitute 0 for x!

$0+2y=12$

$y=6$

Hope this helps!

it takes 21 minutes for 5 people to paint 7 walls. how many minutes does it take 3 people to paint 10 walls

tensa zangetsu [6.8K]

21/7=3mins per wall with 5 people.
Because we assume that all of the people paint at the same rate, 3 X 5=15 mins for one person working alone.
15/3=5 mins per wall with 3 people X 10 people= 50 mins for 3 people to paint 10 walls.

The answer is 50 mins.
