There are 5 candy canes for every 9 presents. How many candy canes are there if there are 108 presents? (PLEASE SHOW YOUR WORK TOO! its for a grade:( )

Answers

Answer:

60 candy canes

Step-by-step explanation:

To find how many candy canes we have to remember that there are 5 candy canes for every 9 presents.

108 is divisible by 9 so we do the equation:

108 ÷ 9 = 12

Now we multiply 12 by 5 since theres 5 candy canes per 9 presents

12 × 5 = 60

To check our work we can divide-

9 ÷ 5 = 1.8

108 ÷ 60 = 1.8

Answer:

The measure of angle a is 45 degrees.

Step-by-step explanation:

Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:

90 + a + a = 180

2a = 180 - 90 = 90

a = 90/2 = 45

a = 45
