1. the sharks aquatic club recently held a fundraiser to raise money for a local charity. the swimmers received money for each lap that they swam during a one-week period. the three swimmers who raised the most money were rita, john, and rodell. together they swam a total of 2125 laps.
john swam three times as many laps as rita, and rodell swam 25 more laps than john. how many laps did each swimmer swim?

a. draw a picture to represent the situation. label the unknown parts with variables and the known parts with their values.

b. determine the number of laps each person swam using the picture you created. explain your reasoning.

c. write an expression for the number of laps each person swam. let l represent the number of laps swum by rita.

d. write an equation to represent this situation.

e. if the swimmers received $2 for every lap they swam, how much did each swimmer earn for charity?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

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.

the answer should be a. snail
