Answer:
She should invest 6976.74 $ principal on daughter's 12th birthday.
Explanation:
We have I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.
Here p + I = 12,000 $
So, I = 12000-p
Interest rate r = 12% =0.12
Number of years = 18 - 12 = 6 years.
Substituting
12000-p = p x 0.12 x 6
p + 0.72 p = 12000
1.72 p = 12000
p = 6976.74 $
So, she should invest 6976.74 $ principal on daughter's 12th birthday.
Answer:
f(3) = 3
Step-by-step explanation:
f(x) = (1/7)(7x)
f(3) = (1/7)(7×3)
f(3) = (1/7)(21)
f(3) = 3
Answer:
Step-by-step explanation:
Graph both equations
The solutions are the coordinates of the intetsection point between the lines.
The coordinates of the intersection point are approximatively (-0.23,-5.12)
So:
● x = -0.23
● y = -5.12
Answer: 20
Explanation:
1/6 of 120
(1/6)(120) or 120/6 = 20
There would be four sides, three around and the bottom base <span />
