Same!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g

Step-by-step explanation:
equation (y=x+2) x y
y=-3+2 -3 -1
y=-1+2 -1 1
y=0+2 0 2
y=2+2 2 4
you can plot the points ( click)
<h2>equation (y=-x) x y</h2>
y=-(-2) -2 2
y=0 0 0
y=-1 1 -1
y=-3 3 -3
plot the points
<h2>equation (y=1) x y</h2>
y=1 no matter what the value of x -3 1
(-3,-1,0,2) -1 1
0 1
2 1
<h2>y=1/2 x +1 x y</h2><h2> y=-4/2 +1 -4 1</h2>
y=-2/2 +1 -2 0
y=1/2(0)+1 0 1
y=3/2 +1 3 2.5
there are no image for 5 and 6
Step-by-step explanation:
Total no. of horses and chicken=24
C+H=24
Total no. horses be =24-C
Total no. legs=66
---66=4(24-C)+2C { As horses have 4 legs and chicken has 2 legs}
66=96-4c+2c
66-96=-2c
-30=-2C
Chicken=15
Therefore no. horses=24-C
=24-15
=9horses
There fore no. of chicken legs=15×2 = 30 legs
Therefore no. of horse legs=9×4=36 legs
