Answer:
60 ml of 40% saline and 90 ml of 15% saline
Step-by-step explanation:
We can call the amount of 40% solution x and the amount of 15% solution y.
x + y = 150 -- (1)
0.40x + 0.15y = 150 * 0.25 -- (2) --- 150 * 0.25 = 37.5
40x + 15y = 3750 (Multiply (2) by 100 to get rid of decimals)
15x + 15y = 2250 -- (3) (Multiply (1) by 15)
25x = 1500 (Subtract (3) from (1)
x = 60
y = 150 - 60 = 90
Answer:
22 degrees
Step-by-step explanation:
158 x 2 is 316
360 - 316 = 44
44 / 2 = 22
and both are the same angles for each set of angles.
Answer:
-8
Step-by-step explanation:
y2 - y1 / x2 - x1
-15 - 1 / 1 - (-1)
= -16 / 2
= -8
