A phone company offers two monthly plans. Plan A costs 8 plus an additional 0.16 for each minute of calls. Plan B costs 20 plus an additional 0.14 for each minute of calls.

Total time when cost are equal = 600 minutes

Total cost = 104

Step-by-step explanation:

Given:

Plan A = costs 8 plus an additional 0.16 for each minute

Plan B = costs 20 plus an additional 0.14 for each minute

Find:

Total time when cost are equal

Computation:

Assume total time = x minutes

Plan A = 8 + 0.16x

Plan B = 20 + 0.14x

Plan A = Plan B

8 + 0.16x =  20 + 0.14x

0.02x = 12

x = 600 minutes

Total time when cost are equal = 600 minutes

Total cost = 8 + 0.16x

Total cost = 8 + 0.16(600)

Total cost = 104

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
