Question 7;
20 mg iodine is given. Since the half life of it 8 days,
It will reduce to 10mg after 8 days. ( 20/2 =10mg)
It will reduce to 5mg after another 8 days. (10/2 =5mg)
It will reduce to 2.5mg after another 8 days.(5/2 =2.5mg)
And it will reduce to 1.25mg after another 8 days.
So after 32 days which is 4 * 8 days, it will be only 1.25mg left.
Question 8a ;
Growth factor is 3 because you multiply every number to get next one. 3*3 =9 , 9*3=27 , 27*3=81
Growth rate is %300 because it is 3 times of the actual number. %100 of number 3 is 3, %200 of number 3 is 6 and %300 of number 3 is 9.
Question 8b;
Model is the first one, y=3^x
Because sequence is orders of 3. 3 order of 1 is 3, 3 order of 2 is 9 , 3 order of 3 is 27.

Answer: $11046.22</h3>
====================================================
Work Shown:
P = amount deposited = 10000
r = interest rate in decimal form = 0.01
n = compounding frequency = 1 (annual compounding)
t = number of years = 10
--------
A = P*(1+r/n)^(n*t) ... compound interest formula
A = 10000*(1+0.01/1)^(1*10)
A = 11046.221254112
A = 11046.22 rounding to the nearest cent
3/4 of 6/7. The of means multiplication.
= 3/4 * 6/7. 2 into 4 is 2 and 2 into 6 is 3.
= 3/2 * 3/7 No other number can divide, so we multiply out.
=9/14
That's the answer.
Answer: 14.8
Step-by-step explanation: If the number in the hundredths place is less than 5, you must round down. On the contrary, if that number is 5 or greater, you must round up. This applies for rounding to any place not just the tenths place. For example, if you were to round it to the ones place, the answer would be 15.
Answer: $550
Step-by-step explanation:
How much is the profit for 1 burrito?: $8 - ($1.50+$1) = $5.5
So, profit for 100 burritos is $5.5 x 100 = $550.
Hope this helps.
