Work out an estimate for the value of
5.1 x 98

Step-by-step explanation:

Given the expression;

We can find the solution by finding the product of the values.

To estimate a number, we first round off the number using general rule, which is, we look at the digit to the right of the digit that we want to round off, if it is less than 5, then value of digit is not changed, if the digit to the right is 5 or more than 5, then the value of digit which we are rounding off get

multiple all that

step-by-step explanation:

27×17

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.
