The prime factorization of 45 is: 3 x 3 x 5.
The prime factors and multiplicities 18 and 45 have in common are: 3 x 3.
3 x 3 is the gcf of 18 and 45.
gcf(18,45) = 9.

A bowling alley charges $15 per game. Customers are not charged to rent bowling shoes.
Dimas [21]

The description shows a linear relationship and a proportional relationship.

<h3>How to describe the given relationship?</h3>

The given parameters are:

Charger = $15 per game

Customers are not charged to rent bowling shoes.

The statement "Customers are not charged to rent bowling shoes" means that the linear function has no y-intercept

So, the linear function can be represented as

y = Charges * x

This gives

y = 15x

Linear functions that are proportional functions are represented as y = mx

In this case, y = mx represents y = 15x

Hence, the description shows a linear relationship and a proportional relationship.

Plz help I have a geometry exam soon!!!!! :(
Pachacha [2.7K]

Answer:

a = 93°, b = 120°, c = 150°

Step-by-step explanation:

b + 36 = 78 × 2 => b + 36 = 156 => b = 120°

87 × 2 - b = the minor arc between a and 78

=> 174 - 120 = 54

54 + b + 36 + c = 360

=> 54 + 120 + 36 + c = 360

=> c = 150°

(c + 36) ÷ 2 = a

=> (150 + 36) ÷ 2 = a

=> a = 93°
