total distance travelled=72+69=141

time taken in hours for journey= (48/60)h + (69/60)= 1.95 h

average speed=141km/1.95h= 72.3km/h (3 sf)

think about the journey as two parts and the total journey.

<u>first</u><u> </u><u>part</u><u>:</u>

first you need to find the speed of the first part but you need to convert 48mins to hours which is 0.8 hours.

speed = 72 ÷ 0.8 = 90km/h.

<u>second</u><u> </u><u>part</u><u>:</u>

then you need to find the time it took to complete the second part of the journey.

time = distance/speed = 69 ÷ 60 = 1.15hours

<u>total</u><u>:</u>

then you can find the total distance for both parts of the journey by doing <em>7</em><em>2</em><em>km</em><em> </em><em>+</em><em> </em><em>6</em><em>9</em><em>k</em><em>m</em><em> </em>which is 141km.

the total time would be <em>0</em><em>.</em><em>8</em><em> </em><em>h</em><em>o</em><em>u</em><em>r</em><em>s</em><em> </em><em>+</em><em> </em><em>1</em><em>.</em><em>1</em><em>5</em><em> </em><em>h</em><em>o</em><em>u</em><em>r</em><em>s</em><em> </em>which is 1.95 hours.

now you have the total distance and time so you can find the average speed for the whole journey.

speed = distance ÷ time

= 141 ÷ 1.95

= 72.307692307.... km/h

<em>(</em><em>y</em><em>o</em><em>u</em><em> </em><em>c</em><em>a</em><em>n</em><em> </em><em>r</em><em>o</em><em>u</em><em>n</em><em>d</em><em> </em><em>y</em><em>o</em><em>u</em><em>r</em><em> </em><em>a</em><em>n</em><em>s</em><em>w</em><em>e</em><em>r</em><em> </em><em>t</em><em>o</em><em> </em><em>7</em><em>2</em><em>.</em><em>3</em><em>k</em><em>m</em><em>/</em><em>h</em><em>)</em>

Rashon has a dimes and y nickels. He has no less than 12 coins worth at most $0.95
Soloha48 [4]

A possible solution of the system of inequalities is 5 dimes and, 8 nickels

<h3>How to determine a possible solution?</h3>

From the question, the given parameters are:

Number of coins = Not less than 12

Worth = At most $0.95

Represent dime with x and nickels with y

So, we have the following inequalities

x + y >= 12

0.1x +0.05y <= 0.95

Next, we plot the graph of the inequalities (see attachment)

From the graph, we have a possible solution to be (5, 8)

This is so because this point is in the shaded region

In the figure, . Find x and y.
zloy xaker [14]

Answer:

The answer to your question is x = 52° and y = 137°

Step-by-step explanation:

Process

1.- Find the value of x using the large right triangle, remember that the sum of the internal angles in a triangle equals 180°.

   x  + 38 + 90 = 180

  x = 180 - 90 - 38

  x = 52°

2.- To find y, we notice that x and y -9 are supplementary angles so their sum gives 180°.

           x + y - 9 = 180

Substitution

          52 + y - 9 = 180

          y = 180 + 9 - 52

          y = 137°
