Anika is on the crew to set up rides for the state fair. The crew does most of the setup on the day that the fair arrives at the fairground and then continues to work on finishing the setup for about a week to have the rides
ready to go in time for the opening of the fair. The scatter plot shows Anika's setup time on different days and
the linear model for the data.
Annika’s Setup Time
Time (Days)

(a) What is the equation of the line, written in slope-intercept form? Show how you determined the
equation.
(b) Anika arrived on Day 0. Based on the linear model you created in Part A, predict how long Anika
worked on Day 0.
(c) Approximately how much did her setup time decrease per day?

Step-by-step explanation:

(a)

coordinates: (8,14), (16,8)

slope:

equation:

y - y1 = m( x- x1)

y - 14 = ( x - 8 )

y - 14 = x +6

y = x + 20

(b)

At day 0, means x will be 0

y = (0) + 20

y = 20

(c)

set up time decrease per day is

answer: b

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
