A concrete mixture is made with 3 parts water and 5 parts cement if 27 parts of water are being used in the current batch of concrete how many parts of cement are being used

45 because there would be an increase in cement parts thus 5×27 which is 135. which is divided by3 to get your answer

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
