2. a) how many milliseconds (ms) are in 1 second? 1. b) how many microseconds (μs) are in 1 second? 2. c) how many nanoseconds (ns) are in 1 millisecond? 3. d) how many microseconds are in 1 millisecond? 4. e) how many nanoseconds are in 1 microsecond? 5. f) how many kilobytes (kb) are in 1 gigabyte (gb)? 6. g) how many kilobytes are in 1 megabyte (mb)? 7. h) how many megabytes are in 1 gigabyte? 8. i) how many bytes are in 20 megabytes? 9. j) how many kilobytes are in 2 gigabytes?

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

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:

no solution.
