aln(c)=ln(c^a)
and
ln(a)-ln(b)=ln(a/b)

so

3ln3-ln9=
ln(3^3)-ln9=
ln27-ln9=
ln(27/9)=

Megan creates a scale drawing of a car. The ratio of her scale drawing length to actual car

Alika [10]

Answer:

Givens

The length of the car in her drawing is 6 cm.
The scale is 3 cm : 2 m.
Ivan draws with a relation 2 cm : 1 m.

First, we need to find the actual length of the car using Megan's ratio.

If 2 centimeters is equivalent to 1 actual meter of the car, 6 centimeters of drawing would be equal to

$M=6cm \times \frac{2m}{3cm} =4m$

Therefore, the car is 4 meters long.

Now, using this information, we can find the length of the scale drawing of Ivan.

$I=4m \times \frac{2cm}{1m}=8cm$

Therefore, Ivan's drawing is 8 centimeters long.

Dan invests £18790 into his bank account. He receives 4.9% per year simple interest. How much will Dan have after 3 years? Give

garri49 [273]

Answer:

£21552.

Step-by-step explanation:

Given information:

Principal amount = £18790

Rate of simple interest =4.9% = 0.049 per year

Time = 3 years

Formula for simple interest:

$I=P\times r\times t$

where, P is principal, r is rate of interest and t is time in years.

$I=18790\times 0.049\times 3$

$I=2762.13$

Total amount after 3 year is

$A=P+I$

$A=18790+2762.13$

$A=21552.13$

$A\approx 21552$

Therefore, Dan have £21552 after 3 years.
