Answer:
Step-by-step explanation:
I'm guessing you have to simplify the expression so...
first, on the top of the fraction there is a 5^2 which is just 25. 25*25 = 625, so the top of the fraction bar changes to 625 * t^8
The denominator is 10^3 = 1000. this changes it to 1000 * t^4
The hard part now is to simplify this. t^8 is just t*t*t*t*t*t*t*t. similarly t^4 is just t*t*t*t
Since there are 4 t's in both the numerator and denominator, this cancels it out and changes this to
which simplifies to 
.
To get rid of the denominator, we multiply 8/8 to the fraction to get:
, which if we distribute the 8 we get: . Which is our answer!
Hope this helps!
Answer:
603.2 meters
Step-by-step explanation:
circle - the outside of the walk in this case. This circle has a
diameter of 22 + 8 m, therefore a radius of 15m. The inner circle
has a diameter of 22m - as given - a radius of 11m.
You subtract the area of the inner circle from that of the larger circle.
I believe the correct answer is 42.25%
Answer:
I believe the second is wrong
To determine the remaining balance, you have to subtract the monthly payment times the number of payments from the purchase price. Speaking mathematically, the equation would be
r = $1350 - $75m
Thus, the answer is letter C.
