Step-by-step explanation:</h2>
Interest, is an additional money paid for borrowing money. it could be simple or compound interest.
simple interest= p×T×R/100
when interest is compounded annually
F= p(1+r)^t
F= future value
p= principal
r= rate
t= time
compound interest is calculated based on the initial and accumulated interest.
<h2>interest Linda earns</h2><h3>fist year</h3>
F= p(n+r)^n
F= 10000(1+0.02)^1
F= 10000×1.02= $10200
interest= 10200-10000
interest = $200
second year
F = 10200(1+0.02)^1
F=10200×1.02= $10404
Interest= 10404-10200
interest= $204
third year
F= 10404(1+0.02)^1
F= 10404(1.02)
F = $10612.08
interest= 10612.08-10404
interest= $208.08
<h2>Bob's interest</h2><h2>I= p×t×R/100</h2>
first year
I=10000×1×0.02/100
interest= $2
second year
I= 10000×2×0.02/100
interest= $4
for the third year
I =10000×3 × 0.02/100
interest= $6
<h2>check answer above for final computation</h2>
"c" is the hypotenuse of the largest triangle, and "a" is that triangle's shortest side. Thus the ratio is
... (longest side)/(shortest side)
Since all the triangles in the figure are similar, to complete the proportion, you need to recognize the triangle that "a" is the longest side of, then find the shortest side of that triangle.
"a" is the longest side (hypotenuse) of the smallest triangle. The shortest side of that triangle is "r". So, your proportion is ...
... c/a = a/r
The appropriate choice is the 2nd one, ...
... r
Use a=

r^2 (r represents your radius of 4 feet)

(4^2)
Answer = 16

29). The 'six' is the same as (6 x 5) = 30 fifths.
So six and three fifths = (30 + 3) fifths = thirty-three fifths.
30). The 'eight' is the same as (8 x 6) = 48 sixths.
So eight and five sixths = (48 + 5) fifths= fifty-three sixths.
31). Twenty-seven of the thirds are the same as (27/9) = 3 .
That leaves a remainder of 2 thirds.
So twenty-nine thirds are the same as 3 and 2/3 .
32). Thirty-two of the fourths are the same as (32/4) = 8 .
That leaves a remainder of one fourth.
So thirty-three fourths are the same as 4 and 1/4 .
