Answer:

$m\angle STR=24^o$

Step-by-step explanation:

we know that

$m\angle STQ=m\angle STR+m\angle RTQ$ ---> by addition angle postulate

we have

$m\angle STQ=48^o$ ----> given problem

$m\angle STR=m\angle RTQ$ ----> given problem

substitute in the expression above

$48^o=2m\angle STR$

Divide by 2 both sides

$m\angle STR=24^o$

A state becomes good if its people are good justify this statement

nadezda [96]

Step-by-step explanation:

Yes, the statement is true "A state becomes good if its people are good". Government is one of the most important body for the good future of any country. The difference between a good and bad country occurs due to its government and governance. Similarly, citizens plays a vital role for the difference between good and bad state. The literacy rate of a state should be high for the sake of becoming good state. A state becomes good if its people are good, as they are representative of the state.

A cell phone company charges a $10 flat fee plus $0.05 per minute for minutes up to 600. For minutes over 600, the company

mash [69]

Answer:

In both the cases, the given total amount is given as:

T = 10 + 0.05 m (when minutes talked m < 600)

T = 40 + 0.15 k (when minutes talked k > 600)

Step-by-step explanation:

Here, the flat fee by the phone company = $10

The charge for each minute for first 600 minutes = $0.05

The per minute cost after 600 minutes = $0.15

Let us assume the number of minutes talked = m

Case 1: when the minutes talked is less than 600 minutes.

Total Charges = Flat Fee + 0.05 x ( the minutes talked)

or, T = $10 + m ($0.05)

or T = 10 + 0.05 m (when m < 600)

Case 2: when the minutes talked is more than 600 minutes.

Let us assume the minutes talked over 600 = k minutes

Total Charges = Flat Fee + Charges for 600 minutes + 0.15 x ( the minutes talked over 600)

or, T = $10 + 600 ($0.05) + k($0.15)

or T = 10 + $30 + 0.15 k (when k > 600)

⇒ T = 40 + 0.15 k (when k > 600)

Hence, in both the cases, the given total amount is given as:

T = 10 + 0.05 m (when m < 600)

T = T = 40 + 0.15 k (when k > 600)
