what would the method be???

Answer:

20 or 21 stakes

Step-by-step explanation:

It would be 20 if you were not able to use the extra wood after cutting two 5.5 foot long segments from each lumber. If you can use the extra 1 foot from each lumber then you would have an extra 10 feet of lumber which you could get one 5.5 foot long stake from.

The number of stakes will be 22.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that 5.5 feet long can be cut from 10 lengths of lumber each 12 feet long.

The total length is calculated as:-

Total length = 12 x 10 = 120 feet

Number of stakes = 120 / 5.5 = 21.81 ≅ 22

Hence, the number of stakes is 22.

Answer:

sorry bro don't read Spanish but it's not over 3

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

2(ax-by)+(a+4b)=0                   .              .               .         1)

2(bx+ay)+(b-4a) = 0              .                 .                 .         2)

Equation 1 gives:

2ax - 2by + a + 4b = 0          .                .             .      1)

Equation 2 gives:

2bx + 2ay + b - 4a    =    0     .              .                   .     1)

Multiplying equation 1 by a and equation 2 by b :

2a²x - 2aby + a² + 4ab = 0

2b²x + 2aby + b² - 4ab = 0

Adding together:

2a²x  +  2b²x + a² + b² = 0

2x (a² + b²) = -(a² + b²)

2x = -1

x = -1/2

Multiplying equation 1 by b and equation 2 by a:

2abx · 2b²y + ab + 4b² = 0

2abx + 2a²y + ab - 4a² = 0

Subtracting:

2y(a² + b²) - 4(a² + b²) = 0

2y(a² + b²) = 4(a² + b²)

2y = 4

y = 2

Answer:

x = -0.18046, 1.84713

Step-by-step explanation:

Since we cannot factor the quadratic, we need to use quadratic formula ([tex]x = \frac{-b+/- \sqrt{b^2-4ac} }{2a}[/tex]):

a = 3

b = -5

c = -1

[tex]x = \frac{-(-5) +/- \sqrt{(-5)^2-4(3)(-1)} }{2(3)}[/tex]

[tex]x = \frac{5+/- \sqrt{25 + 12} }{6}[/tex]

[tex]x = \frac{5+/- \sqrt{37} }{6}[/tex]

Answer:

y = 3x - 17

Step-by-step explanation:

Parallel lines have the same slope so the equation would be y = 3x + b

plugging in the points you get -2 = 3(5) + b

this is -17 = b

Answer:

x = -2

Step-by-step explanation:

Step 1: Substitute h(x) for -9

-9 = 4x - 1

Step 2: Solve for x

-8 = 4x

x = -2

Answer:

x = -2.

Step-by-step explanation:

h(x) = 4x - 1, h(x) = -9.

-9 = 4x - 1

4x - 1 = -9

4x = -8

x = -2

Check your work!

[tex]0.000035km[/tex]

Step-by-step explanation:

[tex]1km =1000m \\ x = 0.035m[/tex]

[tex]use \: \: cross \: \: multipication[/tex]

[tex]0.035 \times 1 = 1000x \\ 0.035 = 1000x \\ \frac{0.035}{1000} = \frac{1000x}{1000} \\ x = 0.000035km[/tex]

Answer:

0.000035 kilometer

Step-by-step explanation:

1 kilometer = 1000 meters

x = 0.035 meter

Let the unknown value be x.

Cross multiplication.

1000 × x = 1 × 0.035

1000x = 0.035

Divide both sides by 1000.

(1000x)/1000 = 0.035/1000

x = 0.000035

Answer:

The correct options are;

The equation of the function is 2·y = -25·x + 200

The equation of the function is y = -25/2·x  + 100

The x-intercept of the function is (8, 0)

Step-by-step explanation:

From the graph of the function, the y-intercept is observed at (0, 100), the x-intercept occurs at (8, 0)

Therefore, we have the slope, m given by the following relation

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where:

y₁ = 100

x₁ = 0

y₂ = 0

x₂ = 8

Which gives;

[tex]m =\dfrac{0-100}{8-0} = -12.5[/tex]

The equation in slope can be found as follows

y - 100 = -12.5×(x - 0)

y = -12.5·x  + 100 = -25/2·x  + 100

Multiplying by 2 gives;

2·y = -25·x + 200

25·x + 2·y =  200

Therefore, the correct options are;

The equation of the function is 2·y = -25·x + 200

The equation of the function is y = -25/2·x  + 100

The x-intercept of the function is (8, 0).

Answer:

    The x-intercept for the function is (8,0).

   The equation of the function is 25x + 2y = 200.

   The equation of the function is y =-25/2 x + 100.

Answer:

Third Choice: a = 2, b = -3, c = -27

Step-by-step explanation:

The equation to be solved with the quadratic formula must be written in the form

ax^2 + bx + c = 0

2x^2 = 27 + 3x

Subtract 3x from both sides. Subtract 27 from both sides.

2x^2 - 3x - 27 = 0

Now we see we have

a = 2, b = -3, c = -27

THIS IS THE COMPLETE QUESTION BELOW;

The probability of pulling a green marble out of a bag of colored marbles is 2:5. If you were to pull colored marbles out of the bag one at a time, and putting the marble back each time for 600 tries, approximately how many time would you select a green marble?? ( explanation too) 7th grade Math

Answer:

We would approximately pick a green marble 240 times

Step-by-step explanation:

Given from the question the probability of pulling a green marble out of a bag of colored marbles is 2:5

Let us denote the number of trials as X

Now the approximately number of times a green marble can be selected would be

=2/5 times

From the question we are given 600 trials

which implies our x=600

Therefore, the number of times we would pick a green marble is:

2/5 × 600 times

≈ 240 times

Therefore, we would approximately pick a green marble 240 times

Answer:

k = 9.64

Step-by-step explanation:

given data

workers w = 305

time t = 2 hour

produce widgets N = 5880.4

solution

we know that here

N  ∝ w × t   .....................1

when we remove directly proportional so here k constant

so equation will be

N = k × w × t    .....................1

put here value and we get

5880.4  =  k × 305 × 2

solve it we get k

k = 9.64
