Answer:
r = 0.046212737
Step-by-step explanation:
A = 14,400 (what your investment originally is)
P = 7,200 (what you want your investment to be)
n = 365 (interest is compounded daily)
t = 15 (15 years)
Plug all of these numbers into the equation, then solve for r
14,400 = 7,200(1 + r/365)^365 · 15
Divide 7,200 on both sides --> 2 = (1 + r/365)^365 · 15
365 · 15 = 5475 --> 2 = (1 + r/365)^5475
5475√(2) = 1 + r/365 (root 5475 both sides to cancel out the exponent)
(5475√(2)) - 1 = r/365 (subtract one from both sides)
((5475√(2)) - 1) · 365 = r (multiply both sides by 365 to isolate r)
Type the left side into the calculator to get r --> 0.046212737.
Hope this helps!
Answer:
there cannot be any solution of the given linear equation.
Step-by-step explanation:
i) the linear equation of 18x +
= 6(3x + 25)
ii) transforming the equation to a simpler form we get
18x +
= 18x + 150 which implies that
= 150 which is not true.
iii) therefore there cannot be any solution of the given linear equation.
Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15
The ratios are not equivalent because when they are reduced, they do not equal the same thing.
Answer:
Eudora spent 0.5 hours in running and 1.5 hours flying using her jet-pack.
Step-by-step explanation:
Let x represent time spent in running.
We have been given that the entire trip took 2 hours, so time spent in flying the jet-packs would be
.
We know that distance is equal to speed times time.

Eudora ran from her home to a secret laboratory at an average speed of 12 km, so distance traveled by running would be
.
Eudora took one of her jet-packs and flew to her school at an average speed of 76 km, so distance covered by jet-packs would be
.
We are told that Eudora traveled a total distance of 120 km. We can represent this information in an equation as:


Combine like terms:



Divide both sides by
:


Therefore, Eudora spent 0.5 hours in running.
Upon substituting
in expression for time spent in flying jet-packs, we will get:

Therefore, Eudora spent 1.5 hours flying using her jet-pack.
