After 7 years, an initial investment of $600 earned $84. Find the interest rate

2%

Step-by-step explanation:

Solving our equation

r = 84 / ( 600 × 7 ) = 0.02

r = 0.02

converting r decimal to a percentage

R = 0.02 * 100 = 2%/year

The interest rate required to

accumulate simple interest of $ 84.00

from a principal of $ 600.00

over 7 years is 2% per year.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
