5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.
3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.
Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is
(3 L) / (8 L) = 0.375 = 37.5%
Answer:
3150 feet for both
Step-by-step explanation:
correct?
Slope = -1/2
y-intercept = 6
<3
Answer:
12.566
Step-by-step explanation:
A = ∫1/2(r)^2dtheta from a - b = 0 to 2π
∫1/2(sin^2theta-4sintheta+4)dtheta
[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…
when you solve this you get 14.137 without taking out the cos(2theta+3)
Answer:
Volume = 120 cubic cm
Step-by-step explanation:
We would apply the formula for determining the volume of a square bases pyramid which is expressed as
Volume = 1/3 x base area x height
From the diagram,
length of square base = 6 cm
The base area = 6^2 = 36
height = 10
Thus,
Volume = 1/3 x 3/6 x 10
Volume = 120 cubic cm
I hope this help you! :)
