X is 3
y is 2
you have to replace x with a zero and divide 12 by it and then you do the same for y
56/90
" / " means divide
56 divided by 90 = 0.62 with a line over the 2 because it is repeating
There are two triangles: a small one to the left and a big one, which includes the small one. They both have a common angle (the leftmost angle) and since (we can assume) the two columns meet the floor at right angles, they both have two equal angles. This means they are similar (AAA).
Let the distance of the base of the stairs to the tallest column be d.
Because matching sides of similar triangles are in the same ratio,
4 / 6 = d / (6 + 12)
4 / 6 = d / 18
(4 * 18) / 6 = d
d = 12
The answer is C
I attached a picture of how I worked out the answer
Hello there, and thank you for asking your question here on brainly.
<em><u>Short answer: B. 0.71
</u></em>
<em>Why?
</em>
To find probability, you have to divide both the total number of possibilities, (7) and divide that by the greatest number of possibilities. (5). <em>5/7 </em>≈ <em>0.71
Hope this helped you! ♥</em>
