PLEASEE help I’m really confused

Answer:

$\frac{13}{\sqrt5}$

Step-by-step explanation:

To get the shortest distance from a point to a line, we need to find a perpendicular line that intersects the line and also intersects the line. We know the slope of the line will be 1/2, but to find the y-intercept, we can just plug it into the point because we already know it will be on the line.

-3 = 1/2(-2)+c

-3 = -1+c

-2 = c

Now, we know the slope and the y-intercept, and since it will intersect the other line, we can set it equal to the other lines formula:

1/2x-2 = -2x+6

5/2x=8

x=16/5

Now, plugging this value of x into any of the equations, we can find the y-coordinate:

16/5(1/2)-2 = -2/5

We have the point (16/5, -2/5)

Now, we need to find the distance between (-2, -3) and (16/5, -2/5)

Plugging into distance formula:

$\sqrt{(-2 - \frac{16}{5})^2+(-3-(-\frac{2}{5}))^2}\\= \sqrt{(-5.2)^2+(-2.6)^2}\\= \sqrt{33.8}$

= $=\frac{13}{\sqrt5}$

how many liters of a 40% acid solution must be added to 12 liters of a 20% solution to obtain a 25% solution

kkurt [141]

Answer:

The answer is 4 liters.

Step-by-step explanation:

We want a final 25% solution, which means that the solvent should constitute 25 percent of all the liters of solution.

Let us call $x$ the litres of 40% solution, so when they are added to the 12 litres of 20% solution, the total litres of the new solution are:

$x+12$

of these liters, 25% must be the solvent:

$N=0.25(x+12)$

Now for the 40% solution, the liters of the solvent are $0.4x$ , and for the 20% liter solution, the liters of solve are $0.2*12=2.4$ liters. Thus the total liters $N$ of the solvent are

$N=0.4x+2.4$

Therefore

$N=0.4x+2.4=0.25(x+12)$

$\therefore x=4\:litres$

bob is twice as old as chuck, and susie is 10 years younger then bob if sum of their ages is 100 years how old is susie

Lina20 [59]

Answer:

The age of Susie is 34 years .

Step-by-step explanation:

Given as :

The statement is ,

Bob is twice as old as Chuck,

Susie is 10 years younger then Bob

The sum of age of Bob , Chuck , Susie = 100 years

Let The age of Bob = B years

Let The age of Chuck = C years

Let The age of Susie = S years

Now, According to statement

Age of Bob + Age of Chuck + Age of Susie = 100 years

i.e B + C + S = 100 years ........1

Again

Age of Bob = 2 × age of Chuck

i.e B = 2 C .......2

Again

Age of Susie = Age of Bob - 10 years

i.e S = B - 10

∵ B = 2 C

So, S = 2 C - 10 ........3

Solving equations 1 , 2 , 3

Put the vale of eq 2 and eq 3 into eq 1

So, 2 C + C + (2 C - 10) = 100

Or, (2 C + C + 2 C ) - 10 = 100

Or, 5 C = 100 + 10

Or, 5 C = 110

∴ C = $\dfrac{110}{5}$

i.e C = 22 years

So, The age of Chuck = C = 22 years

The age of Bob = 2 C = 2 × 22 = 44 years

The age of Susie = S = 2 C - 10

I.e The age of Susie = S = 2 × 22 - 10

Or, The age of Susie = S = 34 years

Hence, The age of Susie is 34 years . Answer
