Answer:
$90
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year,
then, solving our equation
I = 2000 × 0.09 × 0.5 = 90
I = $ 90.00
The simple interest accumulated
on a principal of $ 2,000.00
at a rate of 9% per year
for 0.5 years is $ 90.00.
Answer:
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
Try this:
rx - st = r
remove st from the rx side
rx = r + st
now divide by r
x = (r + st)/r
You now have your expression relating to x
Answer:
A = 53 degrees
B = 90 degrees
Step-by-step explanation:
Every Triangle has 180 degrees
B is 90 degrees because it has a 90 degrees symbol so we know that it is 90 degrees
C is already said as 37 degrees
90 + 37 = 127
So 180 - 127 = 53
Therefore A = 53

Answer:
51
Step-by-step explanation:
Let the middle number be x. Then the 3 numbers will be, x-1, x and x+1. Therefore x-1+x+x+1=51. Therefore: 16+17+18= 51.
