A = 1/2 hb
20 = 1/2 x 4 x b
20 = 2 b
b = 20 /2
b = 10
answer is <span>10 m</span>
Answer:
let w = amt of water required
:
An equation based on the the percent water, an 80% solution is 20% water.
.20(320-w) + w = .50(320)
64 - .2w + w = 160
.8w = 160 - 64
w = 96%2F.8
w = 120 gal of water to produce 320 gal of 50% antifreeze
:
320 - 120 = 200 gal of 80% solution
Water: _120___ gallons
Premium Antifreeze: __200___ gallons
Step-by-step explanation:
<span>if the factors of the polynomial were (x-2) and (x-11), then if anyone of them is equal "0", a polynomial will be equal zero.
x-2=0
x=2
x-11=0
x=11
A polynomial will be equal 0 if x=2, or x=11.</span>
