Answer:

x = 105

y = 64

Step-by-step explanation:

Inside the four sided figure, the angles must add to 360. So 121+70+x+y = 360. You also know that a straight line is 180. This means 116 + y = 180. Using them together you can solve for the variables. Begin by substituting the equation 116 + y = 180 into the other equation.

116 + y = 180 converts to y = 180-116 = 64.

Substitute y = 64 into 121 + 70 + x + y = 360.

191 + x + 64 = 360

255 + x = 360

x = 105

A car valued at £18000 at the start of 2017, depreciated in value by 5% each year for 3 years. How much did it lose in value ove

Anna11 [10]

<u>Answer:</u>

The amount lost over the 3 years s 2567.25£

<u>Explanation:</u>

$\mathrm{F}=\mathrm{I} \times\left(1-\left(\frac{r}{100}\right)\right)^{\mathrm{n}}$

where F = final value after n years

I = initial value of the car in 2017 = £18000 (given)

Since the value is depreciated 5% every year for 3 years,

r = percentage rate of depreciation = 5% (given)

n = 3 years

Substituting these values in formula, we get

$\mathrm{F}=18000 \times\left(1-\frac{5}{100}\right)^{3}$

= $18000 \times\left(\frac{95}{100}\right)^{3}$

= 15432.75£ which is the value of the car after 3 years

Finally 18000-15432.75 = 2567.25£ is the amount lost over this period.

svetoff [14.1K]

Given:

No of users in February is 45,000 and in october its 60,000.

$P=45000(\frac{4}{3})^{(\frac{3}{2})^t}$

t=2

$P=45000(\frac{4}{3})^3$ $P=45000(\frac{64}{27})$ $P=5000(\frac{64}{3})$ $P=106666.6667$

Therefore, approximate no of users after 2 years is 106667.
