Buckets of cement needed is 5 and sand needed is 20

Solution:

Given that Concrete tiles are made using buckets of cement, sand and gravel mixed in the ratio 1 : 4 : 6

cement : sand : gravel = 1 : 4 : 6

Let the cement needed be "1x"

Let the sand needed be "4x"

Let the gravel needed be "6x"

Given that 20 buckets of sand used

4x = 20

x = 5

Thus buckets of cement needed = 1x = 1(5) = 5

Buckets of sand needed = 4x = 4(5) = 20

5 buckets of cement and 20 buckets of sand are needed

Plzzzz help and I'll give you brainliest ​
sdas [7]

Step-by-step explanation:

Left hand side:

4 [sin⁶ θ + cos⁶ θ]

Rearrange:

4 [(sin² θ)³ + (cos² θ)³]

Factor the sum of cubes:

4 [(sin² θ + cos² θ) (sin⁴ θ − sin² θ cos² θ + cos⁴ θ)]

Pythagorean identity:

4 [sin⁴ θ − sin² θ cos² θ + cos⁴ θ]

Complete the square:

4 [sin⁴ θ + 2 sin² θ cos² θ + cos⁴ θ − 3 sin² θ cos² θ]

4 [(sin² θ + cos² θ)² − 3 sin² θ cos² θ]

Pythagorean identity:

4 [1 − 3 sin² θ cos² θ]

Rearrange:

4 − 12 sin² θ cos² θ

4 − 3 (2 sin θ cos θ)²

Double angle formula:

4 − 3 (sin (2θ))²

4 − 3 sin² (2θ)

Finally, apply Pythagorean identity and simplify:

4 − 3 (1 − cos² (2θ))

4 − 3 + 3 cos² (2θ)

1 + 3 cos² (2θ)
