Answer:
Step-by-step explanation:
I think both are the same because you have equations in the formula and what ever you do on one side you do to the other.
Answer:
see the attachments below
Step-by-step explanation:
When the calculations are repetitive using the same formula, it is convenient to put the formula into a spreadsheet and let it do the calculations.
That is what was done for the spreadsheet below. The formula used is the one given in the problem statement.
__
For doubling time, the formula used is the one shown in the formula bar in the attachment. (For problem 11, the quarterly value was used instead of the monthly value.) It makes use of the growth factor for the period used for the rest of the problem.
The doubling time is in years.
__
The doubling time can also be found using a graphing calculator. In the second attachment, we have written a function that shows the multiplier for a given interest rate r and compounding n. The x-intercept in each case is the solution for t that makes the multiplier be 2. The steeper curve is associated with the higher interest rate.
Answer:
- 4 1/2 + 3 1/4
-9/2 + 13/4
the lcm is 4
-18/4 + 13/4
=-5/4
= -1 1/4
Step-by-step explanation:
Answer:
9.3
Step-by-step explanation:
if both travel at same speed they will take equal distance and time to reach the middle and collide.
hence, 27/2 =13.5km
speed=distance/time
time = distance/speed
time= 13.5/87 = 0.15517mm hr
0.15517×60 = 9.31minutes
Your original answer is correct.If you set up a ratio table, it works. For example:
So, they amount of money she's taxed on is $55. We get this by doing 175-20.
$55 is equal to 106% because 6% is tax
Now, you want to find just 100% which is the same as no tax. To get from 106 to 11, you divide by 1.06. So, you also divide 55 by 1.06 to get $51.89
She can't go over this because she won't have enough money.
So, the answer is x≤$51.89
Hope this helps!
