Answer:
The circumference and diameter of a circle
Step-by-step explanation:
Proportional relationships can be written as 
, where 
is some constant of proportionality. The formula for a circumference of a circle can be written as 
, where 
is the diameter of the circle. Therefore, the constant of proportionality is 
and the circumference and diameter of a circle are in a proportional relationship.
Answer: True
Step-by-step explanation:
Given: The ratio of the number of boys to the number of girls at Liam's school is 4:5.
There are 270 students at his school.
Then, Total boys = 
Total girls =
Clearly, (Number of girls) > (Number of boys)
Difference = (Total girls) - (Total boys)
= 150-120
= 30
So, Statement 3: "There are exactly 30 more girls than boys". is absolutely true.
Answer:
First to find AB we use cosine
cos ∅ = Adjacent / hypotenuse
AB is the adjacent
BC is the hypotenuse
cos ∅ = AB/AC
cos 70 = AB / 8
AB = 8 cos 70°
AB = 2.736
AB = 2.7cm to one decimal place
