Rob made 7 brownies. He put nuts on 1 brownie. ​


​ What fraction of the brownies had nuts?

Note that:

 a) 1 unit  of   agricultural production required to obtain 1 agricultural product.

b) 200,000 units of agricultural production are required to obtain 1 of agricultural product.

c) 22,727 units of agricultural production are required to obtain 50,000 units of energy.

d) we need 27,825 units of energy to produce 50,000 units of agricultural products.

a) According to the table, the coefficient of production for agriculture is 0.293, that is

0.293 units of agricultural production = a unit of agricultural product.

b) To obtain 200,000 units of agricultural products we say

0.293 x 200,000,=  58,600 units of agricultural production.

c) the coefficient of production for energy with respect to agriculture is 0.044,

that is ,

0.044 units of agricultural production = a unit of energy.

So

50,000 units of energy,=

0.044 by 50,000,

= 2,200 units of agricultural production.

d) To obtain 50,000 units of agricultural products

use the Leontief inverse of the input-output table, which is simply the inverse of the coefficient matrix.

      [ 3.4175  -0.2345  -0.5565 ]

       [-0.1894   4.8264  -0.2114 ]

       [-0.3074   0.1772   4.8324 ]

       [ (3.4175  x0) +   (-0.2345 x 0) + (-0.5565  x 50,000)  ]

       [ (-0.1894   x0) + (4.8264x 0) + (-0.2114  x50,000) ]

       [ (-0.3074   x0) + (0.1772  x0) + (4.8324  x50,000) ]

       [ -27,825 ]

       [ -10,570 ]

       [ 241,620 ]

Thus, we need 27,825 units of energy to produce 50,000 units of agricultural products.

therefore, the answer is 12828648 deliveries /week​

first we solve the equation for y

on this line the slope is the coefficient of x, so the number that accompanies the variable x

the slope is

for a line to be perpendicular to it, it must have the inverted fraction and the opposite sign to the original slope

then

the slope of the perpedicular line is 4/9

and the slope of a parallel line must be the same slope, so

Answer:

Step-by-step explanation:

Given

\(y = \frac{1}{6}x + 60\)

Required

Interpret the slope and y intercept

The general form of an equation is:

\(y = mx + b\)

Where

\(m=slope\)

\(b = y\ intercept\)

By comparison

\(m = \frac{1}{6}\)

\(b = 60\)

Interpretation:

Slope represents rate and y intercept represents the number of chirps at time 0.

So, the interpretations are:

Slope: The cricket chirps at a rate of \(\frac{1}{6}\) chirps per minute

y intercept: The initial number of chirps is 60

"After first" will be the one comma that is lacking in this sentence. Imani and Jack, the two best runners, came in first and second, so that is the perfect phrase.

In order to create equilibrium, add a comma after a conjunction. We drove to the beach but turned around since there was no more space in the parking lot. The placement of a comma after a conjunction as opposed to before is one of the most frequent mistakes with commas: Nancy always found time despite having a busy schedule to visit the gym.

explanation :

If any of these seven coordinating conjunctions—and, but, for, or, nor, so, yet—are used to unite independent sentences, you should use commas to separate them.

Place commas after the preceding opening (a) sentences, (b) phrases, or (c) words.

3/.25 is the solution

Answer: 97%

Step-by-step explanation:

If for the 3 exams, the mean was 83% and the first two were 76%, that means..

76 + 76 = 152 (divided by two = 76%/current mean)

In order to get an average of 83%, Colin has to have a score that is higher than 76% and somewhat closer to above 90%.

By doing trial and error (testing different percents between 76% and 80%),  you can come to the conclusion that, 76% + 76% + 97% = 249 / 3 = 83

The quotient is 3x + 7, and the remainder is (28x + 9) / (x^2 - 3x).

A division is a process of splitting a specific amount into equal parts.

We have to find 3x³-2x²+7x+9 divided by x²-3x

3x³-2x²+7x+9 is the dividend and x²-3x is the divisor.

The steps to solve this are given below.

Step 1: Take the first digit of the dividend from the left. Check if this digit is greater than or equal to the divisor.

Step 2: Then divide it by the divisor and write the answer on top as the quotient.

Step 3: Subtract the result from the digit and write the difference below.

Step 4: Bring down the next digit of the dividend (if present).

Step 5: Repeat the same process.

Hence, the quotient is 3x + 7, and the remainder is (28x + 9) / (x^2 - 3x).

the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2

Step-by-step explanation:

The computation of the coordinates of the point is shown below:

The angle is

= 4π ÷ 3

The radius is 1 unit

Now

x = rcos\(\theta\), and y = rsin\(\theta\)

Now

x = 1cos(4π ÷ 3) = -1÷ 2

y = 1sin(4π ÷ 3) = -√3÷ 2

Answer:

x - 4 yards.

Step-by-step explanation:

Given:

Area of rectangle = 3x^2 - 12x square yards

Width = 3x yards

To find:

Length of rectangle

Solution:

The area of a rectangle is equal to the product of its length and width.

Area of rectangle = Length * Width

Substituting the given values, we get:

3x^2 - 12x = Length * 3x

Length =( 3x^2 - 12x )3x

Length = x-4

Therefore, the length of the rectangle is x - 4 yards.

Answer: The length of the rectangle is x - 4 yards.

Step-by-step explanation:

We can create an equation to solve this word problem, where the variable L = length.

3x  ×  L  = \(3x^2 - 12x\)

We need to solve for the variable L, to find the length of the rectangle.

First lets factor the right side of the equation to make it easier to divide with.

3x  ×  L  = \(3x^2 - 12x\)

We can factor out 3x from the right side of the equation.

3x  ×  L  = 3x(x - 4)

Now we need to get the variable L by itself (isolating the variable). In order to do that, we can divide both sides by 3x.

3x ×  L  = 3x(x - 4)

/3x           /3x

L = x - 4

The length of the rectangle is x - 4 yards.

The required equation that represent the hanger is 10 + 5x = 11 and the value of x is 1/5.

Given the diagram of the hanger which one side has 10 + 5x  and other side has 11.

To find the equation, equate the expression of one side to the numerical value of the other side. On solving the equation gives the value of x.

Thus, the equation is 10 + 5x = 11.

Consider the equation 10 + 5x = 11

On subtracting 10 from each side gives,

5x = 1

Divide each side by 5 gives,

x = 1/5.

Hence,  the required equation that represent the hanger is 10 + 5x = 11 and the value of x is 1/5.

A probability is a number that reflects the chance or likelihood that a particular event will occur.

Given that, Janet rolls a 6-sided number cube 300 times,

Probability = (Favourable Outcomes)/(Possible Outcomes)

Favourable Outcomes: 5 (1 total)

Possible Outcomes: 1,2,3,4,5,6 (6 total)

Probability of a 5 in any given roll of a die = 1/6

1/6x300 = 50 = 50 predicted roll with 5.
