Part A : The diagram shows a line of best fit with a positive correlation.As the amount of guests increases the amount of pizzas increase supporting the positive correlation.
Part B : I haven't gotta clue sorry
Answer:
Angie will need to save $2.50 for 8 more weeks to get $50
Step-by-step explanation:
Angie has already saved $30
12(2.5)=30
So since she needs $20 more you divide 20 by 2.5 and you get your answer.
20/2.5=8 weeks
Answer:
Area = 23.38 square"
Step-by-step explanation:
It is given that a regular hexagon is having a side = 3"
Since hexagon is inscribed in a circle therefore all the triangles formed by the radii and the sides of hexagon will be equilateral triangles.
In a hexagon number of triangles formed = 6
Area of an equilateral triangle = 1/4s²√3
By putting the value of s = 3"
Area of one triangle = 1/4×3²√3 = (9√3)/4
and we know number of triangles formed inside the hexagon = 6
Therefore area of hexagon = 6×(9√3)/4 = 23.38 square"
Answer is 23.38 square"
The increase of the radius is a linear increase since we have the constant rate of 0.07 inches per second
The equation for a linear growth/decay is given by the form

where

is the rate of increase and

is the value of

when

We have

when
So the equation is 
The length of the radius when

seconds is


inches
If there is a fraction with more then one of the same number repeated behind the decimal, it is a repeating decimal
