Answer:
up 12 over 1
Step-by-step explanation:
Trina borrowed $460 from a friend. Her friend charged her 5% simple annual interest.Let's solve how much will Trina owe her friend in total after 3 years? Use the simple interest formula to solve.
I = prt
I = (460)(0.05)(3)
I = 460 * 0.05 = 23
I = 23 * 3 years = 69 dollars is the interest.
Trina must pay her friend a total of $460 + 69 = 529.
The equation to find a spheres surface area is 4 pi R ^2
and this works in any order
4 * 12 is 48 (4 * R)
48^2 is 2304 ((4 * R)^2)
the exact answer is 2304

the full answer is 7234.56 (((4 * R)^2)

)

Step-by-step explanation:
La question précise que:
36% de 25km
La signification de "OF" mathématiquement = x (multiplication)
Par conséquent:
