Answer:
The replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2 respectively.
Step-by-step explanation:
Given that a pyramid art installation has a surface area of 24 m2, and an artist creates replicas with scale factors of 1/8, 1/10, and 1/12, to determine what is the surface area of each replica, the following calculation has to be done:
24 x 1/8 = 3
24 x 1/10 = 2.4
24 x 1/12 = 2
Therefore, the replicas will have a surface area of 3 m2, 2.4 m2 and 2 m2 respectively.
Answer: The number 0
x^2 + 8x - 4 = x^2 + 8
8x - 4 = 8 ... subtract x^2 from both sides
8x = 12 .... add 4 to both sides
x = 12/8 .... divide both sides by 8
x = 3/2 ... reduce
x = 1.5 .... convert to decimal form
Now plug x = 1.5 into the expression 2x-3 and simplify
2x-3 = 2*1.5-3 = 3-3 = 0 which is the answer
Umm, I don't feel like typing (too lazy and tired to do that lol) so I will attach a written file.
BTW-
Radius is HALF the Diameter.
Diameter is that straight line that goes across the center of the circle.
Radius is basically a line from the center of the circle to any of the side of the circle.
Circumference is basically the perimeter of the circle, or the border or it. It is the Diameter times pi (it said to use 3.14 for pi). It can also be 2 times the Radius times pi (3.14) (since Radius is half the Diameter).
Area is the region inside the circle. Area is the Radius squared (to the power of 2, whatever) times pi (simplified as 3.14).
Okie, now the answers.
^^^Too lazy to put the unit lol.

Answer:
FYAB gives a better deal.
Step-by-step explanation:
Compound interest:

Continuously compounded interest:

For the quarterly compounded interest, r = 0.25%, and n = 4.






For the continuously compounded interest, r =0.23%







The quarterly compounded doubles in 277 years.
The continuously compounded doubles in 301 years.
