Answer:
x=120cc volume of 7% solution
Step-by-step explanation:
Saline solution(7% solution) +
Saline solution (19% solution) = Saline solution (11% solution)
Saline solution(7% solution): (0.07)(x)
x= unknown volume
Saline solution (19% solution): (0.19)(60)
60= given volume
Saline solution (11% solution)= (0.07)(x+60)
x+60= Total volume
solve for x
(0.07)(x) + (0.19)(60) = (0.11)(x+60)
0.07x +11.4 = 0.11x + 6.6
0.11x - 0.07x = 11.4 - 6.6
0.04x = 4.8
x = 4.8/0.04
x = 120 cc volume of 7% solution
Answer:
The answer is B
Step-by-step explanation:
To find the area of a parallelogram you need to multiply base by height
In this problem the base is 67 square ft and the height is 52 square feet 67 times 52 = 3484
Answer:
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
