Hello,
We may suppose that abscisse of C is 21 or 22
As √484=22
Answer D:
<h3>
Answer: 10</h3>
====================================================
Explanation:
The two smaller triangles are proportional, which lets us set up this equation
5/n = n/15
Cross multiplying leads to
5*15 = n*n
n^2 = 75
----------
Apply the pythagorean theorem on the smaller triangle on top, or on the right.
a^2+b^2 = c^2
5^2+n^2 = m^2
25+75 = m^2
100 = m^2
m^2 = 100
m = sqrt(100)
m = 10
Answer:
The correct answer is A.
To find the y-intercept, substitute in 0 for x and solve for y
.
To find 15% of 23000,
23000 x (15/100) = 23000 x 0.15 = 3450
So her salary for the month would be $3450.
