8cm

Step-by-step explanation:

multiply

Answer:

5m 25 cm

Step-by-step explanation:

1 m= 100 cm

3m + 20 cm = 320 cm

2m + 5 cm= 205 cm

2. Add the numbers

320 cm + 205 cm = 525 cm

3. Convert into m again

525/100

5.25 m Or 5 m 25 cm

13.5-6.3=7.2

Answer:

  d/3

Step-by-step explanation:

For k = 8c, the concentration is ...

  S = c/x^2 + 8c/(d -x)^2

The minimum of the function will be found where its derivative is zero. The derivative with respect to x is ...

  S' = -2c/x^3 +(-2)(8c)(-x)/(d -x)^3

We are interested in the value of x that makes this zero.

  0 = -2c/x^3 +16c/(d -x)^3 . . . . . simplify slightly, set S'=0

  0 = (-2(d -x)^3 +16x^3)/(x(d -x))^3 . . . . . combine terms, divide by c

  0 = d^3 -3d^2x +3dx^2 -x^3 -8x^3 . . . . multiply by (x(d-x))^3/(-2)

  9x^3 -3dx^2 +3d^2x -d^3 = 0 . . . . . simplified cubic

Factoring by grouping, we have ...

  (9x^3 -3dx^2) +(3d^2x -d^3) = 0

  3x^2(3x -d) +d^2(3x -d) = 0

  (3x^2 +d^2)(3x -d) = 0

The solution will be found where the second of these factors is zero:

  3x -d = 0

  x = d/3

The concentration of the deposit is a minimum at x = d/3 miles.

_____

The graph shows the minimum is x = 1/3 when d = 1.

The digital root of 5307 is 6

Step-by-step explanation:

Answer:

27.

Step-by-step explanation:

200 / 6 = 33 1/3.

Numbers which are divisible by 5 and 6 are 30, 60, 90, 120, 150 and 180.

So the total is 33 - 6 = 27.

Answer:

27

Answer:

  (4, -7)

Step-by-step explanation:

Maybe you want the solution to this system of equations.

About the easiest way to obtain it is to use a graphing calculator.

   (x, y) = (4, -7)

_____

Additional comment

Since one of the equations gives an expression for y, it is a simple matter to substitute that for y in the other equation.

  4x +(-2x +1) = 9

  2x = 8 . . . . . . . . . . subtract 1 and simplify

  x = 4

  y = -2(4) +1 = -7 . . . use the first equation to find y

ANSWER:

[tex] \large\color{green}{ \tt{A. 1 / 10}}[/tex]

Solution Steps:

Least common multiple of 5 and 10 is 10. Convert 1/5 and 1/10 to fractions with denominator 10.

[tex]( \frac{2}{10} - \frac{1}{10} ) \times 3^{2} - \frac{4}{5} [/tex]

Since 2/10 and 1/10 have the same denominator, subtract them by subtracting their numerators.

[tex] \frac{2 - 1}{10} \times 3^{2} - \frac{4}{5} [/tex]

Subtract 1 from 2 to get 1.

[tex] \frac{1}{10} \times 3^{2} - \frac{4}{5} [/tex]

Calculate 3 to the power of 2 and get 9.

[tex] \frac{1}{10} \times 9 - \frac{4}{5} [/tex]

Multiply 1/10 and 9 to get 9/10.

[tex] \frac{9}{10} - \frac{4}{5} [/tex]

Least common multiple of 10 and 5 is 10. Convert 9/10 and 4/5 to fractions with denominator 10.

[tex] \frac{9}{10} - \frac{8}{10} [/tex]

Since 9/10 and 8/10 have the same denominator, subtract them by subtracting their numerators.

[tex] \frac{9 - 8}{10} [/tex]

Subtract 8 from 9 to get 1.

Answer:

Step-by-step explanation:

y = mx +b

Here , m is the slope and b is the y-intercept

y = (1/2)x - 3

y-intercept = -3

a is right its 58

and in my opinion i think b would be 58*5=290 cents, since nickel is worth 5 cents.

Answer:

Helena is 31.25 meters below the sea level.

Step-by-step explanation:

0.25 x 18 = 4.5

26.75 + 4.5 = 31.25

Answer:

x = 115°

Step-by-step explanation:

The two angles are vertical, so x = 115°

Vertical Angles are two angles formed by the intersection of two lines. Angles that are non-adjacent to each other are congruent in degrees.

We can see that 115° and x° are formed by the intersection of two lines, and they are non-adjacent (don't share a common side) which makes them congruent in degrees.

x = 115°

-Chetan K

Answer:

Step-by-step explanation:

If we want to find the slope, the most easiest way to find the slope is to use 'Rise/Run'. Two points are given, lets use those points and find the slope.

=> We see that the rise is 2. So 2 will be our numerator,

=> We can also see that the run is 3. So 3 will be our denominator.

What do we get?

We get 2/3 as our slope. Therefore, B is our answer. Hoped I helped.

Answer:

4x2−12x+9=0

Step-by-step explanation:

The equation, 2x2+x+3=0, does not have a solution

The equation, x2+5x−3=0, equals -5/2+1/2√37 and -5/2+-1/2√37

The equation, x2−5x+4=0, equal 1 and 4

The equation, 4x2−12x+9=0, equals only 3/2
