Answer:
1%
Step-by-step explanation:
We use the simple interest equation of A=P(1+rt).
A-the total amount with interest earned
P-the initial amount or principal
r-rate
t-time in years
We substitute the values P=6900, A=6923, and t=0.33 since 4 months divided by 12 months is 0.333 years. We then solve for r.

Our final step is to divide both sides by 0.33.

This is the decimal of the rate. We convert to a percentage by multiplying by 100. 0.01(100)=1%.
The formula for the circumference of a circle = 2 x radius x pi
The radius is given as 21 cm and pi = 3.142
Circumference = 2 x 21 x 3.142 = 131.964 cm
Y= -2x+3
-2 is the slope which is given, and 3 is the y intercept which is also given, so plug those numbers in y=Mx+b to make your equation
