So in similar triangles the angles are the same, only the side lengths change so you have to use ratios to find this:
18:22
This is the ratio but it needs to be simplified.
Divide each side by 18 so that the right side is one:
1:1 2/9
now we use this ratio with 12cm where 12 is on the right. You multiply both sides by 12 and it becomes:
12:14 24/9
or
12:16 6/9
or 
12:16 2/3
Therefore the base of the second triangle is 16 2/3 cm

Hope this helps :)

Order the numbers from least to greatest. 0.3, 9/25, 33%, 0.35
Finger [1]

Answer:

0.3(least)

0.33

0.35

0.36(greatest)

Step-by-step explanation:

Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.

To do that, we must divide 9 by 25 to get our answer of 0.36.

Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33

We now have our list, which should be ordered as:

0.3

0.33

0.35

0.36

PLEASE HELP!!!
AfilCa [17]

Answer:

h=\dfrac{10\sqrt{3}}{2}=5\sqrt{3}\ cm.

JP=5\sqrt{3}\ cm

Step-by-step explanation:

Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.

Since EP⊥IJ, then segment JP is the height of the triangle EOJ.

The height of the equilateral triangle can be found using formula

h=\dfrac{a\sqrt{3}}{2},

where a is the side length.

So,

h=\dfrac{10\sqrt{3}}{2}=5\sqrt{3}\ cm.

Therefore JP is 5√3 cm
