In order to construct this equation, we will use the variables:
V to represent mixture volume (40 ml)
C to represent mixture concentration (0.32)
v₁ to represent volume of first solution (40 / 4 = 10 ml)
c₁ to represent concentration of first solution (0.2)
v₂ to represent the volume of the second solution (40 * 3/4 = 30 ml)
c₂ to represent the concentration of the second solution
We know that the total amount of substance, product of the volume and concentration, in the final solution is equal to the individual amounts in the two given solutions. Thus:
VC = v₁c₁ + v₂c₂
40(0.32) = 10(0.2) + 30c
Using the formula a^2+b^2=c^2you can fill in the numbers so that a=height of mattress in inches,b=40 inches or distance from base of the bed and c=48 or length of the ramp. a^2+40^2=48^2a^2+1600=2304
So then it becomes2304-1600=a^2704=a^2 26.5+=aSo, The top of the mattress(after rounding) is 26.5 inches off the ground.
Answer:
64.89 is the total cost
Step-by-step explanation:
63 x .03 = 1.89
63 + 1.89 = 64.89
Answer:
Step-by-step explanation:
(a) H0: μ_D=0
Ha: μ_D ≠ 0
b) Find attached the solution
(c) By technology,
p - value = 0.4437
Hence,
the p-value is 0.4437
First we multiply 50 and 13 and 3/4
13 and 3/4 could also = 13.75
sooo lets multiply
50 x 13.75 = 687.50
so $687.50 was spent on the stock
now lets fund out how much they sold them for
we multiply 12 and 50
50 x 12 = 600
now we need to find out the loss by subtracting
$687.50 - $600 =$ 87.50
so that means this company lost $87.50 :(
hope this helps :)
