Answer: 4/9
Step-by-step explanation: To multiply fractions, first multiply across the numerators, then multiply across across the denominators.
So here, we have 2 · 2 which is 4 and 3 · 3 which is 9.
So we have 4/9 which is in lowest terms.
This means that 2/3 · 2/3 is 4/9.
P(4)= 1/8
This is because there are 8 equal parts and 4 is just one of those 8 parts.
Setup
remember is means =, and of means *
Writing across the words
15 = x * 39
15/39 = x
x =0.3846 = 38.46%
Answer:
Part a): 100 degrees
Part b): Isosceles Triangle
Step-by-step explanation:
Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.
180 - 80 = 100
Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.
