Answer:
- $9,000 at 15%
- $4,000 at 10%
Step-by-step explanation:
Let x represent the amount borrowed at 15%. Then the amount borrowed at 10% is (13000-x). The interest at the end of the year is ...
0.15(x) + 0.10(13000 -x) = 1750
0.05x = 1750 -1300 . . . . . . . . . . . . simplify, subtract 1300
x = 450(20) = 9000 . . . . . . . . . . multiply by 20
$9,000 was borrowed at 15%; $4,000 was borrowed at 10%.

Answer:
72.14 units
Step-by-step explanation:
Let A(8,13), B(5,-18),C(-6,-6) and D(-2,-5)
Apply the distance formula as;
Finding the lengths of the segments
For AB
For BC
For CD
For DA
Finding the perimeter will be;
31.14+16.28+4.12+20.6=72.14 units
By the power of Trigonometry!
We know the angle is 22*. The height of the ramp is on the OPPOSITE side of the angle. The known length of 32 ft is the ADJACENT side of the angle.
Q: Which trig function relates OPP and ADJ?
A: It's tangent!
tan(angle) = opposite / adjacent
So, we can say that
tan(22*) = opposite / 32
32*tan(22*) = opposite
With a calculator (make sure it is in degree mode!):
32*0.404 = opposite
12.928 ft = opposite
The height is 13 ft.
