PHYSICS As a ray of light meets a mirror, the light

<h3>Answer:  37 degrees</h3>

========================================================

Explanation:

The angle of incidence is equal to the angle of reflection. The angle of light coming in is the same as the angle of light bouncing out. Each angle is made with the dashed line as the diagram shows.

So angle RMI = 106 is bisected, i.e. divided in half, to get

  • Angle RMN = 53
  • Angle NMI = 53

since 106/2 = 53

Then notice that the horizontal dashed line is perpendicular to the vertical mirror. This means angle NMJ is a 90 degree angle and,

angle RMJ = (angle NMJ) - (angle RMN)

angle RMJ = 90 - 53

angle RMJ = 37 degrees

----------

In short: divide 106 in half to get 53, then subtract it from 90

The expresion 14.42d + 12.24c can be used to find the total cost of d punds of almonds and c pounds of cashews how much does it
madam [21]

Answer:

Therefore the total cost of 3\frac{1}{2} pound of almonds and 3\frac{1}{2} pound of cashews is

y=\frac{36.05}{d}+\frac{30.6}{c}

[Where y is in $]

Step-by-step explanation:

[The unit of price is not given, I assume the unit of cost as $]

Given expression is 14.42 d + 12.24 c .

Where the amount of almond is denoted by d pounds.

and  the amount of cashews is denoted by c pounds.

The cost price of d pound of almond is $14.42.

The cost price of 1 pound of almond is \$\frac{14.42}{d}

Then the cost of 3\frac{1}{2} pound of almond is =\$\frac{ 14.42 \times3 \frac{1}{2} }{d}

                                                                 =\$\frac{36.05}{d}

Again from the given expression we get that,

The cost price of c pound of cashews is $12.24

The cost price of 1 pound of cashews is =\$\frac{12.24}{c}

Then the cost of 3\frac{1}{2} pound of cashews is =\$\frac{ 12.24 \times3 \frac{1}{2} }{c}

                                                                    =\$\frac{30.6}{c}

Therefore the total cost of 3\frac{1}{2} pound of almonds and 3\frac{1}{2} pound of cashews is

y = =\frac{36.05}{d}+\frac{30.6}{c}

[Where y is in$]

√(x2-x1)^2+(y2-y1)^2

sqrt(8-7)^2+(41-4)^2

sqrt(1)^2+(37)^2

sqrt 1+1369

sqrt 1370

= about 37. 01
