Arestaurant has 18 tables and 54 chairs. the
ratio of tables to chairs in the restaurant is
1: 3
1: 4
3: 1
54: 1

The ratio is 1:3

Step-by-step explanation:

Let

x -----> the number of tables in the restaurant

y ----> the number of chairs in the restaurant

we know that

To find out the ratio of tables to chairs in the restaurant, divide the number of tables by the number of chairs

we have

so

The ratio is equal to

Simplify

Divide by 18 both numerator and denominator

therefore

The ratio is 1:3

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

part a: 1.08

part b: 27.59
