To send a letter to Country Q, the postal service charges: $0.79 for the first ounce and $0.55 for each additional ounce. How much would it cost to send a letter that weighs 8 ounces?

$4.64

Step-by-step explanation:

The first ounce is charged at $0.79 and then every additional ounce is $0.55.

There are 8 ounces to send.

The cost will therefore be:

= Cost of first ounce + Cost of 7 additional ounces

= 0.79 + (0.55 * 7)

= 0.79 + 3.85

= $4.64

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°
