Answer:

The amount of acid in the solution will be: 55.4 millimeters

Step-by-step explanation:

The total amount of solution of acid and water = 342 milimeters

The percentage of acid included in the solution = 16.2%

The amount of acid in the solution:

[tex]16.2\%\:\times 342[/tex]

[tex]=\frac{16.2}{100}\times \:342[/tex]

[tex]=\frac{162}{1000}\times \:342[/tex]

[tex]=0.162\times \:342[/tex]

[tex]=55.4[/tex] millimeters

Thus, the amount of acid in the solution will be: 55.4 millimeters

Answer:I think its 68

Step-by-step explanation:

Answer:

The measure of angle N is 68 degrees.

Step-by-step explanation:

Since this shape is a parallelogram, opposite angles will be equivalent. So to start, set (6x - 2) equal to (4x + 36).

— 6x - 2 = 4x + 36

Next, subtarct the 4x from both sides of the equation as well as add 2 to both sides of the equation an simplify.

— 6x - 4x - 2 + 2 = 4x - 4x + 36 + 2

— 2x = 38

Now, divide both sides of the equation by 2 to find the value of x.

— 2x/2 = 38/2

— x = 19

Finally, substitute 19 for every x in the original equation. Simplify.

— 6(19) - 2 = 4(19) + 36

— 114 - 2 = 76 + 36

— 112 = 112

We now know that these two angles are 112 degrees. If a parallelogram's angles must add up to 360 degrees, then subtract 112 twice from 360 to find the combined total angle measure of N and Q. Then divide that number by 2 to find the measure of N.

— 360 - 112 - 112 = 136

— 136/2 = 68

The measure of angle N is 68 degrees.

Succesorul primului număr 999 = 1000

Al doilea este cu 1872 mai mare= 1872 + 1000 = 2872

Al treilea care sunt primele două împreună = 1000 + 2872 = 3872

∴

Suma celor trei numere = 1000 + 2872 + 3872

Answer:

3/8

Reason:

I just did a question exactly like this, and this was the answer.

The value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex].

Trigonometric functions are  the periodic functions which denote the relationship between angle and sides of a right-angled triangle.

We have,

[tex]Sin(A) = \frac{4}{5}[/tex] ,    [tex]\frac{\pi }{2} < A < \pi[/tex]

[tex]Sin(B) = \frac{-2\sqrt{5} }{5}[/tex] ,   [tex]\pi < B < \frac{3\pi }{2}[/tex]

So,

Using identity ;

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

So,

First find [tex]SinB[/tex] and [tex]CosA[/tex];

i.e.

[tex]CosB=\frac{-\sqrt{5} }{5}=\frac{-1}{\sqrt{5} }[/tex],   [tex]\pi < B > \frac{3\pi }{2}[/tex]

[tex]CosA=\frac{-3}{5}[/tex],    [tex]\frac{\pi }{2} < A > \pi[/tex]

Now,

Substituting values,

[tex]Cos(A - B)= CosA\ *\ Cos B + Sin A\ *\ Sin B[/tex]

[tex]Cos(A - B)= ((\frac{-3}{5})\ *\ \frac{-1}{\sqrt{5}} ) +((\frac{4}{5})\ *\ \frac{-2\sqrt{5} }{5} )[/tex]

Simplify,

[tex]Cos(A - B)= (\frac{3 }{5\sqrt{5}} ) -(\frac{8 }{5\sqrt{5}})[/tex]

[tex]Cos(A - B)= (\frac{-5 }{5\sqrt{5}} )[/tex]

[tex]Cos(A - B)= (\frac{-1 }{\sqrt{5}} )[/tex]

Or we can write

[tex]Cos(A - B)= (\frac{-\sqrt{5} }{5} )[/tex]

Hence, we can say that the value of [tex]Cos(A - B)[/tex] will be [tex](\frac{-\sqrt{5} }{5} )[/tex] which is given in option (b).

Answer:

The equation in the point-slope form will be:

Step-by-step explanation:

Given

Using the point-slope form of line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

here

substituting the values m = 2/3 and the point (-3, 5)  in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

Thus,  the equation in the point-slope form will be:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

NOTE: The equation in the point-slope can be further simplified such as:

[tex]y-5=\frac{2}{3}\left(x-\left(-3\right)\right)[/tex]

[tex]y-5=\frac{2}{3}\left(x+3\right)[/tex]

Add 5 to both sides

[tex]y-5+5=\frac{2}{3}\left(x+3\right)+5[/tex]

[tex]y=\frac{2}{3}x+7[/tex]

Answer:

w = -20

Step-by-step explanation:

-[tex]\frac{w}{5}[/tex] + 9 = 13

Shift the (+9) to the other side of the equation. (+9) will turn into (-9).

-[tex]\frac{w}{5}[/tex] = 13 - 9

   = 4

Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).

-w = 4 × 5

    = 20

Multiply both sides of the equation by (-1) so that -w will turn into w.

w = (-1) × 20

w = -20

I think the right answer is c 4:12

Answer:

(C) - C for Correct!

Step-by-step explanation:

We can look at ratios as a fraction, so 1:3 = 1/3 and 12:36 = 12/36. We can simplify the second fraction into 12/36 = 1/3 by canceling 12 from the numerator and denomerator. We can do this with all of the answer choices:

(A) Wrong - 2/18 = 1/9

(B) Wrong - 4/9

(C) Correct - 4/12 = 1/3

(D) Wrong - 6/6 = 1

Answer:

36

Step-by-step explanation:

Since the 3 numbers have a ratio of 2:3:7, that means it simplifies to that. So, there must be a common factor, let’s say x, for each of the numbers. Thus, the numbers are 2x, 3x, and 7x. To find the mean, we add up all of the numbers and divide by the number of numbers: (2x + 3x + 7x)/3 = 12x/3 = 4x = 48. Dividing by 4 on both sides gets x = 12. The median of the numbers is the number in the middle which is 3x. Substituting x = 12, we get: 3(12) = 36.
