Answer:
ok the rest
Step-by-step explanation:
7.05 is the correct answer
The quantities in the proportion you give add to 16 pounds, of which 2 pounds are cement. That is, cement constitutes 1/8 of the total weight.
For each yard of concrete, 4000 lb/8 = 500 lb of cement are used.
For 12.5 yards of concrete, 12.5 * 500 = 6,250 pounds of cement will be used.
_____
"yard" in this case is shorthand for "cubic yard".
Answer: i think its g+1
Step-by-step explanation: Okay so since the values are given to you all you have to do is substitute.
12-(4*12) divided by (3*4)+1
12-48 divided by 12+1 ( I did the multiplication first because it comes first in the order of operations.)
-36/13= -2.76
So this is not equal to 3.
