Answer:
do you still need the answer lol I can edit my answer if u still need it
Step-by-step explanation:
There are 40 animals at a petting zoo.
Adult goats→x Child goats→a
Adult rabbits→y Child rabbits→b
<span>
There are twice as many adult rabbits as adult goats: y=2x
</span>There are three times as many child goats as adult goats: a=3x<span> There are exactly as many adult rabbits as there are child rabbits: b=y=2x
x+y+a+b=40⇒x+2x+3x+2x=40
8x=40⇒x=40/8⇒x=5
There are 5 </span><span> adult goats are in the petting zoo.</span>
f(x) = 8x + 1. Start by subtracting 1 from both sides.
f(x) - 1 = 8x. Divide both sides by 8.
(f(x) - 1) / 8 = x.
the inverse of f(x) = 8x + 1 is f^-1(x) = (x-1) / 8
D = 2w + 50
Plug in 14 for w.
D = 2(14) + 50
D = 28 + 50
D = 78
Therefore the corresponding table entry for D would be B. 78
Answer:
0.19g/mL
Step-by-step explanation:
The concentration of a solution is how much of a substance in in another substance, usually the amount of solute in a solvent.
The solute is the active ingredient powder. The solvent is the NS solution.
Divide the solute by the solvent.
75g ÷ 400mL
= 75g/400mL Simplify for solute per one unit, 1 mL. Divide top by bottom.
= 0.1875g/mL Round to the nearest hundredth, second decimal place.
≈ 0.19g/mL
Therefore the final concentration is 0.19g/mL.
