How far does the tip of the minute hand of a clock move in 25 minutes if the hand is 9 inches long?

so let's recall that a circle, has a total of 360°, so the circular clock has a total of 360°, and it also has 60 minutes, so, how many degrees for 1 minute?  360/60 = 6.  So there are 6° in 1 minute, then in 25 minutes the minute hand has travelled 25 * 6 degrees, namely 150°, and that' the central angle for 25 minutes then.  Since the hand is 9 inches long, that'd be the radius.

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.

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
