Answer:

Area of a regular polygon formulas

Step-by-step explanation:

area = n * a * ri / 2 , having ri - incircle radius (it's also an apothem - a line segment from the center to the midpoint of one of its sides)

area = perimeter * ri / 2 , given ri and polygon perimeter.

area = n * (ri)² * tan(π/n) , given ri.

In how many years will Rs.1200 at the rate of 15% interest amount to Rs. 1740

Anvisha [2.4K]

Find the interest amount.

$I=1740-1200=540$

Use the formula for simple interest.

$I=prt/100$

Solve for t.

$540=1200 \times 15\% \times t$

$540=1200 \times \frac{15}{100} \times t$

$540=180t$

$t=\frac{540}{180}$

$t=3$

13.48x - 200 < 256.12

podryga [215]

Answer:

x < 33.84

Step-by-step explanation:

we have

13.48x-200 < 256.12

Solve for x

Adds 200 both sides

13.48x-200 +200 < 256.12+200

13.48x < 456.12

Divide by 13.48 both sides

13.48x/13.48 < 456.12/13.48

x < 33.84

The solution is the interval ----> (-∞, 33.84)

All real numbers less than 33.84
