Tom and linda stand at point a. linda begins to walk in a straight line away from tom at a constant rate of 2 miles per hour. one hour later, tom begins to jog in a straight line in the exact opposite direction at a constant rate of 6 miles per hour. if both tom and linda travel indefinitely, what is the positive difference, in minutes, between the amount of time it takes tom to cover the exact distance that linda has covered and the amount of time it takes tom to cover twice the distance that linda has covered?

imo e - 108

case 1: 6∗t1=12∗(t1+1)∗2=> t1=156∗t1=12∗(t1+1)∗2=> t1=15 hour = 12 minutes

case 2: 6∗t2=2∗(t2+1)∗2=> t1=2=1206∗t2=2∗(t2+1)∗2=> t1=2=120minutes

difference = 120-12 = 108 minutes

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

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.
