slava [35]

Answer:

8 years

Step-by-step explanation:

Compound interest formula

$A(t)= A_0(1+\frac{r}{n})^{nt}$

A(t) is the final amount 55000

A_0= 40000, r= 4% = 0.04, for quarterly n=4

$55000=40000(1+\frac{0.04}{4})^{4t}$

divide both sides by 40000

$1375=(1+\frac{0.04}{4})^{4t}$

$1375=(1.01)^{4t}$

Take ln on both sides

$ln(1375)=4tln(1.01)$

divide both sides by ln(1.01)

$\frac{ln 1375}{ln 1.01}=4t$

Divide both sides by 4

t=8.00108

So it takes 8 years

2 + 3 × 16 − 2 × 21 − 3 = <br> 5<br> 14<br> 35<br> 40

Ganezh [65]

Answer: 5

Step-by-step explanation:

Since, According to the BODMAS, when we solve an expression,

We follow the following sequence,

1. Bracket/ parenthesis

2. Of

3. Division

4.Multiplication

5. Addition

6. Subtraction

Here, the given expression is,

$2 + 3\times 16 - 2\times 21 - 3$

Thus, solving the given expression by following the BODMAS,

We get,

Step 1. $2 + 48 - 42 - 3$

Step 2. $50 - 42 - 3$

Step 3. $8-3$

Step 4. 5
