Answer:
614.2857143
Step-by-step explanation:
The base angles of an isosceles triangle are equal
The base angles are 15 degrees, while the vertex angle is 150 degrees
The base angles are given as:
Base = (6a- 3) and (a + 12)
So, we have:
Collect like terms
Divide both sides by 5
Substitute 3 for a in Base = (6a- 3),
So, the base angle is 15 degrees.
The vertex angle is calculated using:
So, we have:
Hence, the vertex angle is 150 degrees

Answer: they can rent the room for less than 6 hours.
Step-by-step explanation:
Let x represent the possible amounts of time in which they can rent the room.
There is a reservation fee of $47 and an additional hourly fee of $7.40. This means that the total cost of renting the room for x hours would be
47 + 7.4x
The math club wants to spend less than $91.40 on renting the room. This would be expressed as
47 + 7.4x < 91.4
7.4x < 91.4 - 47
7.4x < 44.4
x < 44.4/7.4
x < 6
Answer:
a. An observational study
Step-by-step explanation:
An observational study is a study that has to do with the observation of individuals involved in the study. In such a study, zero effort is put to change the outcome.
This question tells us that the random sample of 291 individuals that underwent the weight loss program would go through a system of follow up to find out the change in weight. Therefore the design of the study is clearly an observational study.
