Answer:
hence rate interest r = 41.176%
Step-by-step explanation:
The amount borrowed= $680
amount payed back = $750
therefore, interest incurred = 750-680= $70
time, t= 3 months = 3/12= 0.25 years
rate%, r
we know that SI= 
70= 
r=
hence rate interest r = 41.176%

Step-by-step explanation:
Hope this helps :)
Δ=88
1) Using the Quadratic Equation to Solve
3x²-8x+1=3
3x²-8x+1-3=3-3
3x² -8x -2=0
2)Let's find the discriminant
Δ= (-8)²-4(3)(-2)
Δ=64 -4(3)(-2)
Δ=88
The formula for a triangl is one-half base time height ( 1/2 bh).
So for this triangle, input the base and height.
1/2 (10 x10)
The solve
1/2 (100)

The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²
<h3 /><h3>How to find the surface area of a cylinder?</h3>
Surface area of a cylinder = 2πr(r + h)
Therefore,
radius is tripled = 3(7) = 21 inches
height is shrunk half its size = 17 / 2 = 8.5 inches
Therefore,
surface area = 2 × 3.14 × 21 (21 + 8.5)
surface area = 131.88(29.5)
surface area = 3890.46 inches²
