Andy invests £12 000 in a variable rate compound interest account.
The interest is
2% for the first year
3.5% for the second year
5% for the third year
Work out the value of Andy's investment at the end of 3 years.
One year later :
[tex]12000 + 12 000 \times \frac{2}{100} = \\ [/tex]
[tex]12000 + 120 \times 2 = [/tex]
[tex]12000 + 240 = 12240[/tex]
That's for first year.
_________________________________
One year later :
[tex]12240 + 12240 \times \frac{3.5}{100} = \\ [/tex]
[tex]12240 + 122.4 \times 3.5 = [/tex]
[tex]12240 + 428.40 = [/tex]
[tex]12668.4[/tex]
That's for second year.
_________________________________
[tex]12668.4 + 12668.4 \times \frac{5}{100} = \\ [/tex]

brainlllyy i need an answer what’s the slope of this line
Answer:
4/5
Step-by-step explanation:
The slope of the line is 4/5.
To find out the slope of a line, you must remember rise over run. Using that, you count up from whenever the line meets an actual whole number, which in this case it is -2, and then count up 4, and then you start counting right to meet the point (3, 4). The number of spaces you go to the right is 5, making the slope 4/5.
Hope this isn't too confusing and that it helps :)

The measure of the angles is 108degrees
Lines and anglesFrom the given diagram, the given measures are alternate exterior angles and they are equal.
Given the following parameters
<A =6x +18
<B = x + 93
Equate
6x + 18 = x + 93
6x - x = 93 -18
5x = 75
x = 15
Determine the measure of the angles
<A = <B = 6x + 18
<A = <B = 6(15) + 18
<A = <B = 108 degrees
Hence the measure of the angles is 108degrees

27·243
Answer:
27 · 243 = 3
=
Answer:
3^8 and 6,561
Step-by-step explanation:
1) Calculate, 3 to the power of what is 27?
Make a table of all of 3's powers until 10. i.e. 3^1 = 3, 3^2 = 9 ......
You will find that 3^3 = 27 and 3^5 is 243
3) Use the formula x^m * x^n = x^m+n and substitue our value.
It should look like this: 3^3 * 3^5 = 3^3+5 = 3^8
4) Make a table as described in step 2 and calculate all of 3's powers up to 10. Look at your table and you will find that 3^8 is equal to 6,561
5) The expression written as a power is
3^8 and
the value: 6,561

Answer:
x=15
Step-by-step explanation:
4 I x-5 I +20 = 60 Distribute the 4
4x - 20 + 20 = 60 Combine like terms :
4x - 0 = 60
4x = 60 Divide:
x = 15
Check : 4 I 15 - 5 I + 20 = 60
4 I10I +20 = 60
40 + 20 = 60
60 = 60 ✔
Hope this helps :)
Answer:
x = 15Step-by-step explanation:
so simplify the first half of the equation
4x-20+20 = 60
combine like terms
4x = 60
divide both sides by 4
x = 15

Answer:
A.
Step-by-step explanation:
It's literally the same equation written in reverse, which according to the commutative property, can be done.
Answer: A
Step-by-step explanation:
For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.
We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.
We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].
We can eliminate D because (-1×-7) given you 7, not -7.
Therefore, A is the right answer.
