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:
You can use the equation a^2+b^2=c^2 using this you can find that the value of the 3rd side is 5 hope this helps <3
C=2pi(r)
Pi=3.14
r=5.5
So C=2(3.14)(5.5)=34.56
So the circumference is 34.56 mi
And the area is A=pi(r)²
So you have
A=3.14(5.5)²
So A=95.03 mi²
So the area is 95.03 mi² and the circumference is 34.56 mi
Hope this helps!
