To solve this, we are going to use the compound interest formula:
where
is the final amount after
years
is the initial investment
is the interest rate in decimal form
is the number of times the interest is compounded per year
For the first 4 years we know that:
,
,
, and since the problem is not specifying how often the interest is communed, we are going to assume it is compounded annually; therefore,
. Lest replace those values in our formula:
Now, for the next 6 years the intial investment will be the final amount from our previous step, so
. We also know that:
,
, and
. Lets replace those values in our formula one more time:
We can conclude that Collin will have <span>£3691.41 in his account after 10 years.</span>
Answer:
The answer is -4
Step-by-step explanation:
-2x-6<=1
-2(-4)-6<=1
8-6<=1
2<=1 which is False
-2x-6<=1
-2(-3)-6<=1
6-6<=1
0<=1 which is True
-2x-6<=1
-2(-2)-6<=1
4-6<=1
-2<=1 which is True
-2x-6<=1
-2(-1)-6<=1
2-6<=1
-4<=1 which is True
Answer:
I Kg = 1000 g
3 Kg = 3000 Kg
Step-by-step explanation:
Kg - Hg - Dag - g
1 Kg - 10 Hg - 100 Dag - 1000 g
So, 1 Kg = 1000 g
3 Kg = 3(1000)g = 3000 g
Answer:
Choice 4 (s - 3 = 12)
Step-by-step explanation:
I think you made a reading error on this question, as it said "for which equation is s = 9 <em>not</em> the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable <em>s</em> of each equation.
1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.
2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.
3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.
4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.
Choice 4/D is the correct choice.
Answer:<em> If that's 44 then your answer is going to be 132 but if it is just 4 is going to be 12 if it is 4.4 then it's going to be 13.2 </em>
Step-by-step explanation:
44x3=132
4x3=12
4.4x3=13.2
