Answer:

The correct option is;

CGB

Whereby, we have;

Triangle RKB ~ Triangle CGB

Step-by-step explanation:

The given triangles have the following congruent angles;

Angle ∠RKB on triangle ΔRKB is congruent to angle ∠CGB on triangle ΔCGB

We are given angle ∠KBR on triangle ΔRKB is congruent to angle ∠GBC on triangle ΔCGB

Therefore, ΔRKB is similar to ΔCGB by the Angle-Angle (AA) rule for similarity.

Customers of a satellite dish company must pay for installation of the dish, and a monthly fee for service. After 6 months, Ryan

FromTheMoon [43]

Cost of installation fee is $120.

Step-by-step explanation:

Let,

Monthly fee = x

Installation fee = y

According to given statement;

6x+y=594 Eqn 1

11x+y=989 Eqn 2

Subtracting Eqn 1 from Eqn 2

$(11x+y)-(6x+y)=989-594\\11x+y-6x-y=395\\5x=395\\Dividing\ both\ sides\ by\ 5\\\frac{5x}{5}=\frac{395}{5}\\x=79\\$

Putting x=79 in Eqn 1

$6(79)+y=594\\474+y=594\\y=594-474\\y=120$

Cost of installation fee is $120.

URGENT, PLEASE HELP! (1/5) -50 POINTS- !please no wrong answers for the points.! A) <img src="https://tex.z-dn.net/?f=y%20%3D%20

Stells [14]

Answer:

C y = 3/2x - 1/8

Step-by-step explanation:

We know that the line has a positive slope, because it goes up from the lower left to upper right

We can eliminate B and D

For y = 6x - 11/8

A slope of 6 is very steep

Putting in 6

y = 6*6 -approximately 1 = 35 so the value at 3 would be 35

This is too big

Checking C

y = 3/2(6) - 0 = 9 or 9 This would be about right

3. Consider the following diagram.

yawa3891 [41]

Answer:

m = 3, n = 6

Step-by-step explanation:

The hypotenuse leg (HL) theorem states that two triangles are said to be similar if one leg and the hypotenuse of the triangles are congruent.

From the diagram, comparing the hypotenuse of the triangles;

4m + 1 = 13

4m = 13 - 1

= 12

m = $\frac{12}{4}$

= 3

m = 3

Also, comparing the sides;

2m + n = 8m - 2n

substitute the value of m to have,

6 + n = 24 - 2n

collect like terms,

n + 2n = 24 - 6

3n = 18

n = $\frac{18}{3}$

= 6

n = 6

m = 3, n = 6
