A bank advertises an interest rate of 4% per year, compounded monthly

Darina [25.2K]

Given :

Interest rate , r = 4 %.

To Find :

The APY .

Solution :

APY is given by :

$APY=(1+\dfrac{r}{n})^n-1$

Here , r is compound interest and n is number of time compounded .

So ,

$APY=(1+\dfrac{r}{n})^n-1\\\\APY=(1+\dfrac{4}{12})^{12}-1\\\\APY=30.57\%$

Therefore , APY is 30.57 % .

Hence , this is the required solution .

Equation 1: m = 8 + 2n

slava [35]

Answer:

1:×4

m×4=(8+2n)×4

4m=32+8n

now,

1:×4 - 2:

4m-4m = 32+8n -4+4n

0=(32-4) +(8n-4n)

0=28+4n

28=-4n

n= -7

n=-7. 1:,

m=8+2n

m=8+2×(-7)

m=8-14

m=-6

If x and x+ 10 are a pair of adjacent angle find them

ikadub [295]

Answer:

85° and 95°

Step-by-step explanation:

Given that , x and x + 10 are a pair of angles .

If they will be pair of angles on the same line , then their sum will be 180° .

=> x + x + 10° = 180°

=> 2x = 180° -10°

=> 2x = 170°

=> x = 170°/2

=> x = 85° .

<h3>Hence the two angles are 85° and 95° .</h3>
