Comunative property I hope it is right
Answer:
1.4%
Step-by-step explanation:
You can only include 7 and 8 in the answer because it didn't include 6 in the question. add the frequency for both of those sizes (14) and divide by the total (1000) to get the probability. multiply by 100 to get answer as a percent. 1.4%
since nalah is 10 years old and she got the doll when she was 6 we can do 10 - 6 = 4 so 4 years she has had the doll.
Answer:
Step-by-step explanation:
An isosceles triangle has 2 sides that are the same length. Let's say that our triangle has the 2 sides measuring the same and the base is a different length. The vertex angle is the top angle. By the definition of an isosceles triangle, since the 2 sides measure the same length, then the angles across from those sides have the same degree measure. If we know the measure of the vertex angle, then we have
180 = vertex angle - base angle - base angle
but since the base angles are the same and we have 2 of them, then
180 = vertex angle - 2 base angles
For example, if the vertex angle measures 80 degrees, then 180 - 80 = 100. That 100 has to be split in half for each of the base angles which are the same as each other. So the vertex angle is 80 and each base is 50.
