9 yd to the power of 3 soil containing 35% clay was mixed into 6yd to the power of 3 of soil containing 10%
clay. What is the clay content of the
mixture?

11.5%

The dry pure clay is stronger than the dry pure sand, because dry clay is found to have moisture content of 11.5%. However, this strength can only be achieved at a strain level approximately four times higher than that of the sand.

Step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.
