During construction the workers need to mix dried bentonite into the concrete as it is being mixed to get the desired consistency. The workers decide to mix 800 mg of bentonite to be mixed with 198 lb of concrete mixed every 8 hours. The information for the concrete shows that 25-75 mg/kg per day is the appropriate mixture consistency. Are the workers within the desired range?

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

the answer is c hope it

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
