Julia and Kajal make deliveries on their bicycles. For each delivery, they need some time to get ready, and then they each ride at a constant speed.
Julia takes 404040 minutes to make a delivery 555 kilometers away. She uses 101010 minutes of the delivery time to get ready.
The following equation gives the time it takes Kajal to make a delivery (in minutes) as a function of the distance of the delivery (in kilometers).
t = 15+6dt=15+6dt, equals, 15, plus, 6, d
Who takes more time to get ready?

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.

[tex]\text{area of walls and ceiling}=(2*40*15)+(2*3*15)+(40*3)[/tex]

[tex]\text{area of walls and ceiling}=1200+90+120[/tex]

[tex]\text{area of walls and ceiling}=1410[/tex]

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,

[tex]\text{ the total painting cost}=10*(\frac{1410}{25})[/tex]

[tex]\text{ the total painting cost}=10*56.4=564[/tex]

therefore, the total painting cost is $564.

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

[tex]\text{area of floor} = 40*3\text{ square meters}[/tex]

[tex]\text{area of floor} =120\text{ square meters}[/tex]

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

[tex]\text{total cost for tiles} = 3*120 = 360[/tex]

therefore, the total tiles cost is $360.

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

[tex]\text{combined total cost}= 564+360 = 924[/tex]

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