I've seen this question before and it's word for word
They will make a triangle
Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed =
For Abby,
8 =
distance = 8(x + 30) ................. 1
for Melissa,
9 =
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.

<h2>
Answer:</h2>
Account B will yield more.
<h2>
Step-by-step explanation:</h2>
Savings account A and savings account B both offer APRs of 5%
But savings account A compounds interest annually, while savings account B compounds interest monthly.
Lets check which account will yield more :
<h2>
Account A.</h2>
Lets take p = 10,000
r = 5% or 0.05
n = 1
t = 1
Compound interest formula is :
Substituting values in formula;
= $10500
<h2>
Account B:</h2>
Lets take p = 10,000
r = 5% or 0.05
n = 12
t = 1
Compound interest formula is :
Substituting values in formula;
= $10510
We can see that account B gives more yield as compared to account A. When an account is compounded monthly, we earn interest on interest. This is why we yield more.
Therefore, account B will yield more.
