Answer:

C.-5x + Y=2

Step-by-step explanation:

Given :

Slope (m)=5

Point $(x_1,y_1)=(0,2)$

Solution :

General form of equation of line : $y-y_1=m(x-x_1)$

Where m is the slope

Substituting the values in the general form

$y-2=5(x-0)$

$y-2=5x$

Since the standard form of line is Ax+By=C

So, solving further

$-5x+y=2$

Hence Option C is correct

I'm not really sure what to do.

I’m not sure if this is right but this looks a bit like chemistry so maybe try to get from minutes to seconds as it becomes an ‘S’ which I’m assuming is seconds? so basically try to do dimensional analysis with it and see if that works. Don’t forget to square it though, that’ll throw you off.

Answer:

<h2>25 square inches </h2>

Step-by-step explanation:

Given, 

Parallel sides of the trapezium = 3in, 7in

Height of the trapezium = 5in

Therefore, 

Area of the trapezium

$= \frac{1}{2} \times sum \: of \: parallel \: sides \times height$

$= \frac{1}{2} \times (7 + 3)in \times 5in$

$= \frac{1}{2} \times 10in \times 5in$

= 5in × 5in

$= {25in}^{2}$

Hence,

Area if the trapezium is 25 square inches (Ans)

The blood alcohol (C2H5OH) level can bedetermined by titrating a sample of blood plasma with an acidicpotassium dichromate solut

NISA [10]

Answer:

Step-by-step explanation:

In acidic reaction , equivalent weight of potassium dichromate is

mol weight / 6

= 294 / 6

49 g

equivalent weight of alcohol = 46 g

31.05 cc of .06M of potassium dichromate

= 31.05 x .06 cc of M potassium dichromate

= 1.863 cc of M potassium dichromate

= 1.863 x 6 cc of N potassium dichromate

= 11.178 cc of N potassium dichromate

== 11.178 cc of N alcohol

= (11.178 / 1000 ) x equivalent weight of alcohol

= (11.178 / 1000 ) x 46 g

= .514 g

30 g of blood contains .514 g of alcohol

100 g of blood contains (0.514 / 30) x 100

= 1.71 % of alcohol.

Solutions to the question please. The answer is 3.6km

Afina-wow [57]

Let the Distance between A and B be : C km

Given : The Man Travels from A to B at a Speed 4 km/h

⇒ The Man Travels 4 km in One Hour during his Journey from A to B

⇒ $The\;Man\;Travels\;One\;km\;in\;\frac{1}{4}\;Hour\;during\;his\;Journey\;from\;A\;to\;B$

⇒ $The\;Man\;Travels\;C\;km\;in\;\frac{C}{4}\;Hour\;during\;his\;Journey\;from\;A\;to\;B$

Given : The Man Travels from B to A at a Speed 6 km/h

⇒ The Man Travels 6 km in One Hour during his Journey from B to A

⇒ $The\;Man\;Travels\;One\;km\;in\;\frac{1}{6}\;Hour\;during\;his\;Journey\;from\;B\;to\;A$

⇒ $The\;Man\;Travels\;C\;km\;in\;\frac{C}{6}\;Hour\;during\;his\;Journey\;from\;B\;to\;A$

⇒ $The\;Total\;Time\;Taken\;by\;the\;Man = \frac{C}{4} + \frac{C}{6} = \frac{3C + 2C}{12} = \frac{5C}{12}\;Hour$

We know that One Hour contains 60 Minutes

⇒ The Total Time taken by Man = $\frac{5C}{12}\times60\;Min = 25C\;Min$

Given Total Time Taken by Man is 45 Minutes

⇒ 25C = 45

⇒ $C = \frac{45}{25} = 1.8\;km$

But the Total Distance Traveled by the Man is 2C

⇒ 2C = 2 × 1.8 = 3.6 km

⇒ The Total Distance Traveled by the Man is 3.6 km
