Step-by-step explanation:
Answer:
Yes a 1:3 ratio
Step-by-step explanation:
Yes triangle A is 3 times bigger than triangle B. So it takes 3 B triangles to make one A triangle.
The correct answer is B. Supplementary
That is the basic definition of what supplementary angles are and can be found in any textbook.
Answer:
15 different swing sets
Step-by-step explanation:
The swing set is composed by one swing and one slide.
There is 5 different types of swing, so there are 5 possibilities to fill the one swing we need.
There are 3 different types of slides, so there are 3 possibilities to fill the one slide we need.
So, to find the total number of swing sets, we just need to multiply the swing possibilities and the slide possibilities:
Number of sets = 5 * 3 = 15 different sets
3:5=x:50
Therefore 5 ×x = 50
x = 10
Therefore 3 × 10 = 30
therefore 30 blue pens
proof = 30 blue + 50 red= 3+ 5
therefore 80 = 8x
