Answer:

30.6

Step-by-step explanation:

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The length of the side j is 30.6 cm.

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]

where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,

Sin B is the angle and β is the length of the side of the triangle opposite to angle B,

Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.

Given the length of i is 53 cm, while the measure of the ∠I is 120°. Also, the measure of ∠J is 30°. Therefore, the length of the side j is,

[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}\\\\\dfrac{Sin\ I}{i} =\dfrac{Sin\ J}{j} \\\\\dfrac{Sin\ 120^o}{53} =\dfrac{Sin\ 30^o}{j} \\\\j = \dfrac{Sin\ 30^o \times 53}{Sin\ 120^o}\\\\j = 30.5995 \approx 30.6\rm\ cm[/tex]

Hence, the length of the side j is 30.6 cm.

Answer:

There are 12 pentapods and 8 Tripods, which in total add up to 84 feet.

Step-by-step explanation:

Given that both the Tripods and the Pentapods have, at least, 3 feet (the Pentapods have 5), and that in total between both groups they add 20 heads and 84 feet, the following logical reasoning can be made:

If there are 20 heads, there are 20 Martians in all. Each of them has, at least, 3 feet, with which in principle the 20 Martians would add up to a total of 60 feet (20 x 3). Therefore, there is a surplus of 24 feet (84 - 60).

If the Pentapods have 2 feet more than the Tripods, the number of Pentapods in the total Martians is determined by that difference. Thus, if there are 24 feet left, there are 12 Pentapods (24/2).

Therefore, in the group of Martians there are 12 pentapods (12 x 5 = 60) and 8 Tripods (8 x 3 = 24), which in total add up to 84 feet (60 + 24).

Slope = - 2

Step-by-step explanation:

Step 1:

y = mx + b          Slope Intercept

Step 2:

2x + y = 10        Equation

Step 3:

y = - 2x + 10       Subtract 2x on both sides

Step 4:

m = Slope

Answer:

Slope = - 2

Answer:

[tex]a_{n}[/tex] = 5n - 22

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₂ = - 12 , then

a₁ + d = - 12 , that is

a₁ + 5 = - 12 ( subtract 5 from both sides )

a₁ = - 17

Thus

[tex]a_{n}[/tex] = - 17 + 5(n - 1)

    = - 17 + 5n - 5

     = 5n - 22

Second from top...

The average rate of change is $0.07, meaning that for each minute of talk time, the monthly bill increases by $0.07.

Step-by-step explanation:

Pick any two points and calculate the slope which will represent the rate of change:

  (Minutes, Cost)

  (0, 9.95)

  (10, 10.65)

Rate of change:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (10.65 - 9.95) / (10 - 0)

             = 0.7 / 10

             = 0.07

y is cost

m is rate of change

x is minute(s) use

b is fixed monthly cost regardless if any minutes is used

  y = mx + b

  y = .07x + 9.95
