Jack read 20 pages of a book in 60 minutes. How many pages can he read in 75 minutes at the same rate? Write a proportional equation. Please help!!

To find how many pages jack reads per minute, divide 60 by 20.

60 ÷ 20 = 3

Jack read 3 pages per minute.

Now, find how many pages he will read in 75 minutes by multiplying 3 by 75.

3 × 75 = 225

--

The proportional equation is the number of pages read per minute (3) times the time spent reading (r) equals total pages read (t).

t = 3r

Hope this helps :)

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.
