A Pharmacist whishes to mix a solution that is 6% Minoxidil. She has on hand 100 ml of 4% solution and wishes to add some 8% sol

dangina [55]

Answer:

100

Step-by-step explanation:

Let x be the amount to be added of the second solution. For every 100ml of it 8 units of minoxidil are added. The total amount of solution will be (100 + x), so the final concentration is given by:

$4 / (100 + x) + 0.08x / (100 + x) = 0.06$ [Multiplying by (100 + x)]

$4 + 0.08x = 6 + 0.06x$ [Transposing terms]

$0.08x - 0.06x = 6 - 4$ [ operating]

$0.02x = 2$ [Dividing by 0.02]

$x=100$

Find the surface area of the rectangular prism.

amm1812

Answer:

70 m²

Step-by-step explanation:

Red sides:

2 x ( 5 x 5 ) = 2 x 25 = 50

Blue side :

2 x ( 1 x 5) = 2 x 5 = 10

Green :

2 x ( 1 x 5 ) = 2 x 5 = 10

Total surface area:

50 + 10 + 10 = 70

Units : m²

Surface Area = 70 m²

Please help asap!! binomial factor

ser-zykov [4K]

Answer:

3x - 8

Step-by-step explanation:

the factors of the following equation $9x^{2} - 64 =$ are:

$(3x - 8)(3x + 8)$

If you look the equation you can notice that you don´t have a term like -48x or 48x, so the factors must have a positive and negative sign.

Remember first you need to multiply each segment and finally add.

$(3x - 8)(3x + 8) = 9x^{2} - 24x + 24x -64$ = $9x^{2} - 64 =$
