Answer:

x= 2/a (apex)

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

a) Let the numbers be n, n + 2 and n + 4

Sum = n + n + 2 + n + 4

= 3n + 6.

As n must be even (2, 4, 6 and so on) , 3n must be divisible by 6  and 3n + 6 is divisible by 6 also.

b) 3n + 6 = 6000

3n =  5994

n = 5994/3 = 1998

So the numbers are 1998, 2000 and 2002.

Answer:

  (25 -5√7)/3 ≈ 3.924 inches

Step-by-step explanation:

After removing squares from the corners and folding up the sides, the open-top box will have dimensions ...

  x × (20 -2x) × (30 -2x)

The maximum value for this cubic expression in the domain 0 < x < 10 is found easily by a graphing calculator to be at x = 3.924 inches.

__

You can solve this by expanding the cubic and finding the solution that makes its derivative equal to 0.

  V(x) = 4x^3 -100x^2 +600x

The derivative is ...

  V'(x) = 12x^2 -200x +600 = 0

Dividing by 12, we have ...

  x^2 -50/3x +50 = 0

Completing the square, we get the form ...

  (x -25/3)^2 = -50 +(25/3)^2 = (-450 +625)/9 = 175/9

Taking the square root gives ...

  x -25/3 = ±(5√7)/3

The solution in the desired range is ...

  x = (25 -5√7)/3 ≈ 3.924 . . . inches

Additional comment

We limit the value of x to half the width of the cardboard material, as any longer cuts would overlap to create a negative box dimension. The graph shows the maximum volume to be about 1056.3 cubic inches. Box dimensions would be 3.924 in deep by 12.153 in by 22.153 in.

__

The generic solution can be found using a similar procedure. For cardboard dimensions a×b, it will be ...

x = ((a +b) -√((a -b)² +ab))/6

Step-by-step explanation:1 third of 9 is 3. Half of 10 is 5. Multiply 5 by 3. It is now 15.

Answer:

15

Step-by-step explanation:

Work backwards:

half of 10 = 10 ÷ 2 = 5

so ... nine times half of 10 = 9 × 5 = 45

so  ... ⅓ of nine times half of ten = ⅓ of 45 = 45 ÷ 3 = 15

Answer:

x = 5/2, -12

Step-by-step explanation:

(2x-5)(x+12) = 0

2x-5 = 0

2x = 5

x = 5/2

x + 12 = 0

x = -12

Answer:

x = 5/2          x = -12

Step-by-step explanation:

(2x-5)(x+12)=0.

Using the zero product property

2x-5 =0         x+12=0

2x=5              x = -12

x = 5/2          x = -12

Slope of a line perpendicular is  [tex]\frac{-5}{2}[/tex]

Step-by-step explanation:

Hey there!

The given equation is ; 2x - 5y = -40.

Or, 2x - 5y + 40 = 0

Slope of the equation is;

[tex]slope(m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

[tex]m = \frac{ - 2}{ - 5} [/tex]

[tex]m = \frac{2}{5} [/tex]

Therefore, the slope of equation is 2/5.

Now; For the perpendicular lines:

Slope of equation * slope of next line = -1

i.e M1*M2= -1

[tex] \frac{2}{5} \times m2 = - 1[/tex]

[tex]2 \: m2 = - 5[/tex]

[tex]m2 = \frac{ - 5}{2} [/tex]

Therefore, the slope of the line which is perpendicular line to 2x - 5y + 40= 0 is -5/2.

Answer:

0.2830

Step-by-step explanation:

edge

The required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

As per the given condition, if the fish is between 22 and 23.5 inches,

P(22≤ X ≤ 23.5)

You can rewrite it as:

⇒ P(X ≤ 22) - P(X ≤ 23.5)

The first step is to standard both values before using population data and the standard normal distribution to get the probability:

The formula of the standard normal is Z=(X-μ)/σ

⇒ P(Z ≤  (23.5-24)/1.4) - P(Z ≤ (22-24)/1.4) = P(Z ≤-0.36) - P(Z ≤ -1.43)

Now you look at the table of the Z-distribution for the cumulative probabilities for both z-score

⇒  (1 - 0.6406) - (1 - 0.9236)

⇒ 0.3594- 0.0764 = 0.2830

Hence, the required proportion of red drum fish would be 0.2830 between 22 and 23.5 inches in length.

Answer:

v=13

Step-by-step explanation:

3(13) = 39+11 = 50

Answer:

Our main goal is to isolate the variable here (v).

And if we want to solve this equation,

we must utilize inverse operations.

Given that:-

3v + 11 = 50

We always first get rid of the constants.

And in this case, 11 is our constant.

So the inverse operation of addition is subtraction (because 11 is being added)

-11        -11

3v = 39

Now, we are left with a co-efficient.

To isolate v, we must apply the inverse operation of multiplication which is division (because 3 and 'v' are being multiplied).

Answer: 12m by 4m.

Step-by-step explanation: You are looking for the dimensions of the room here, also known as the length and width.

Let’s make width equal to x since we don’t know what the value is. Length is going to be x + 8 since the diagonal is 8m MORE than the width.

w = x

l = x + 8

Use the equation for the perimeter.

P = 2l + 2w

Plug in your values:

32 = 2(x + 8) + 2(x)

Now, solve for x! First start by distributing the 2:

32 = 2x + 16 + 2x

Next, add like terms:

32 = 4x + 16

Subtract 16 from both sides:

16 = 4x

Divide by 4 on both sides:

4 = x

Now we have x, but remember, x is equal to the width. We just solved for width so now we need length.

l = x + 8

Plug in your x and solve:

l = 4 + 8

l = 12

Your length is 12m and your width is 4m, therefore, the dimensions of the rectangular room are 12m by 4m.
