Increase £14187.13 by 4.5%
Give your answer rounded to 2 DP.

The new value is $14,825.55

Step-by-step explanation:

In this question, we are intending to increase a certain value by a certain percentage.

To do this, we find the direct percentage on that value and add to that value.

Finding the percentage, we have;

4.5% of 14187.13 = 4.5/100 * 14187.13 = 638.42

we now proceed to add this vale to the value we have found the percentage of

That would be 638.42 + 14187.13 = £14,825.55

The new amount is £14825.55

Step-by-step explanation:

To increase the ammount given by 4.5 % we can make a rule of three in a way that 14187.13 is related to 100% in the same proportion that "x" is related by 4.5%, then we sum the original value by "x". We have:

£14187.13 -> 100%

£x -> 4.5%

14187.13/x = 100/4.5

100*x = 14187.13*4.5

x = 14,187.13*4.5/100

x = 63,842.085/100

x = 638.421

The new amount is given by:

new amount = 14,187.13 + 638.421 = £14,825.55

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
