Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Number of painters to paint the interior of a house = 2

According to question, amount of time it takes to paint the house is inversely related to the number of painters.

So, Time is inversely related to number of painters.

If the number of painters to paint the house = 6

So, we get

\frac{2}{6}=\frac{x}{12}\\\\2\times 12=6\times x\\\\24=6\times x\\\\\frac{24}{6}=x\\\\4\ hours=x

Hence, it will take 4 hours to paint the house by 6 painters.

Therefore, Option 'C' is correct.

Answer:

b = 6 sqrt(2)

Step-by-step explanation:

Since this is right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

3^2 + b^2 = 9^2

9+b^2 = 81

b^2 = 81-9

b^2 = 72

Take the square root of each side

sqrt(b^2) = sqrt(72)

b = sqrt(36*2)

b = 6 sqrt(2)

mihalych1998 [28]

Answer:

1100 square inches

Step-by-step explanation:

The faces are all rectangles (area = length x width)

Area of bottom:  20 x 10 = 200

Area of front: 20 x 15 = 300

Area of back (same as front) = 300

Area of right side: 10 x 15 = 150

Area of left side (same as right side) = 150

Total of all the sides: 1100
