74 are the two significant figures after rounding
This is a geometric progression
- Common ratio=1/16÷1/4 =1/4
- first term =a=1/4
So
The general formUla is
Answer:
B
Step-by-step explanation:
Part A:
3(m+54) = 381 shows that 54 is being added to m, the initial sum. Then it shows the sum of 54 + m being multiplied by 3 to get to the new balance of $381. This equation most accurately matches with the question.
Part B:
3(m-54) = 381.
You would first divide both sides by 3.
m - 54 = 127
You would now add 54 to both sides.
You now know m = 181.

Answer: G) -2</h3>
=======================================================
Explanation:
I'm assuming you meant to say (a+y)^2 + 2y
Replace each copy of 'a' with 5. Replace each copy of 'y' with -3. Use PEMDAS to simplify.
(a+y)^2 + 2y
(5 + (-3))^2 + 2(-3)
(5-3)^2 + 2(-3)
(2)^2 + 2(-3)
4 + 2(-3)
4 - 6
-2
So (a+y)^2 + 2y = -2 when a = 5 and y = -3.
Answer:
( the third choice)
Step-by-step explanation:
Let 
be the radius of cylinder A and let 
be the radius of cylinder B. We assume the heights of both cylinders are the same
Base circumference of cylinder A = 
Base area of cylinder B = 
In order to have (2) have the same value as (3) we must multiply by a factor of
