Let,

The unknown angle measure be x°.

We know that,

Sum of all angles of a Quadrilateral measures 360°.

So,

⇒∠QPR + ∠PSR + ∠SRQ + ∠RQP = 360°

⇒ 120° + 60° + 70° + x° = 360°

⇒ 180° + 70° + x° = 360°

⇒ 250° + x° = 360°

⇒ x° = 360° - 250°

⇒ x° = 110°

Therefore, the names of the angles & their values will be,

⇒∠QPR = 120°

⇒∠PSR = 60°

⇒∠SRQ = 70°

⇒∠RQP = 110°

A train leaves at 14.54 and arrives at its destination at 15.47. If the train travelled 66 km, what was it's average speed in km
JulijaS [17]

Answer: average speed of the train = 4,483.0 km/h

Step-by-step explanation:

Speed = Distance / Time

Distance = 66 km

Time = 15.47  cancelling 15, we have 60 sec added to 47 sec

         <u> - 14.54</u>

=         14.   107    60 + 47

         <u> - 14.  54</u>

<u>                     53secs</u>

53secs to hours becomes =

60 secs = 1 min

60 min= i hour

therefore 53seconds =53/3600=0.0147222hours

Speed= 66/ 0.0147222= 4,483.025

Rounding to 1 dp becomes= 4,483.0 km/h

Item 11 Identify the independent and dependent variables. The equation c=0.09s gives the amount c (in dollars) of commission a s
diamong [38]

Answer:

C is dependent variable

S is independent variable

Step-by-step explanation:

Here, give the equation, we are told to identify the independent and the dependent variable

When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation

While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable

now looking at the question, the equation we have is as follows;

c = 0.09s

To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received

Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales

Hence, while commission represents the dependent variable, the values of the sales are the independent variables

Given the function f(x) = log3 (x + 1), determine f^−1(2).
zavuch27 [327]
Given:  <span>f(x) = log3 (x + 1), look for f^-1 (2)

We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:

</span><span>f^-1 (2) = 8</span>
