Hector is rewriting the expression 7 to the power of 11 in expanded form. how many terms will be multiplied in his rewritten expression? a: 2 b: 7 c: 11 d: 12

C. 11

Step-by-step explanation:

We know that Hector is writing the expression in the expanded form.

Now, = 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7 × 7

i.e. 7 is multiplied 11 times in order to obtain the result .

Thus, we see that there are 11 terms being multiplied in the expanded form.

Hence, option C is correct.

the answer is 62.8 cubic units

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.
