<h2>Answer:</h2><h2>The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle = bh .. (2)
substitute (1)in (2), we get
Area = (2h-3) h
10 = (2h-3) h
20 =
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
keeping in mind that
x = percent rate for the 17000 investment.
y = percent rate for the 11000 investment.
so the amount for the 17000 interest will just be (x/100) * 17000, or namely 170x.
and the amount of interest earned for the 11000 is (y/100) * 11000, or just 110y.
now, regardless of what "x" and "y" are, we know that the interest from the 17000 is higher by 308 bucks, therefore 170x = 110y + 308.
we also know that the rate of <u>x</u> is higher as well than <u>y</u> by 0.4%, so then x = y + 0.4.
