Dmitri needs 6 liters of a 16% solution of sulfuric acid for a research project in molecular biology. He has two supplies of sul

mylen [45]

Answer:

4 litres of 12% solution

2 litre of 24% solution

Step-by-step explanation:

Let the 12% solution = l

Let the 24% solution = h

Dimitri needs a total of 6 litres of both :

l + h = 6 - - - - - - - - (1)

He needs a mixture of both volumes of both to give a 16% volume

12%l + 24%h = 16% * 6

0.12l + 0.24h = 0.96 ----(2)

From (1)

l + h = 6;

l = 6 - h

Substitute l =6-h into (2)

0.12(6 - h) + 0.24h = 0.96

0.72 - 0.12h + 0.24h = 0.96

0.72 + 0.12h = 0.96

0.12h = 0.96 - 0.72

0.12h = 0.24

h = 0.24 / 0.12

h = 2

From ;

l = 6 - h

l = 6 - 2

l = 4

Please help me with..... A rectangular garden is 50 feet longer than it is wide its perimeter is 284 feet

zmey [24]

P=2 (l+w)
we know P=284
we also know that l= w+50
so replace l in the equation with w+50

284=2 (w+50+w)
284=2 (2w+50)
divide both sides by 2
142=2w+50
subtract 50 on both sides
98=2w
divide both sides by 2
49=w
so width is 49, and we need to add 50 to it to find the length
l= 49 +50
l=99

LabTech is a company that manufactures microscopes and other laboratory instruments. On (Ipoint) occasion, one of the microscope

Virty [35]

Answer:

probability of 1st defective = 0.844

correct option is d. 0.844

Step-by-step explanation:

given data

probability defective = 0.17%

undefective microscopes = 100

to find out

the probability that the first defective microscope

solution

we know defective probability P = 0.17% = 0.0017

so non defective probability (1-P) = 1 - 0.0017

non defective probability (1-P) = 0.9983

and

1st defective come after 100 it mean 1st 100 are non defective so

probability of 1st defective = $(1-P)^{100}$

probability of 1st defective = $(0.9983)^{100}$

probability of 1st defective = 0.844

so correct option is d. 0.844

a1/b1 = 4

a2/b2 =4

a1/b1 = b1/b2 ≠ c1/c2

∴ The pair of linear equations in two variables is said to be inconsistent and do not have any solution.
