A. 16 lbs
b. 11 lbs
c. 20 lbs
d. 10 lbs

Step-by-step explanation:

in what form do you need the equation ?

I assume it is the slope-intercept form :

y = ax + b

"a" being the slope of the line, "b" being the y-intercept of the line.

the slope of a line is the ratio

y-coordinate difference / x-coordinate difference

when going from one point on the line to another.

and the y-intercept (y-axis intercept, to be precise) is the y-value when x = 0.

so, starting with the slope, we go for example from (1, 6) to (6, 1) :

x changes by +5 (from 1 to 6).

y changes by -5 (from 6 to 1).

so, the slope is

-5/+5 = -1

so, we know, our equation looks like

y = -x + b

to get "b" we use one of the points, e.g. (1, 6) :

6 = -1 + b

b = 7

and our final equation is

y = -x + 7

The solution of the expression is 3.659

First, we will start with the expression inside the brackets, i.e., [(3 1/3 * 1.9) + (19.5 / (4 1/2)]. Here, we have two operations - multiplication and division. According to PEMDAS, we need to perform multiplication before division.

To simplify this expression, we will first convert 3 1/3 to an improper fraction. 3 1/3 is the same as 10/3. Therefore, the expression inside the brackets becomes

=> [(10/3 * 1.9) + (19.5 / (9/2)].

Next, we will simplify the multiplication first -

=> 10/3 * 1.9 = 19/3.

Now, let's simplify the division operation

=>  19.5 / (9/2) = 4.33

Therefore, the expression inside the brackets becomes

=>  [(19/3) + 4.33] = 8.99

Moving on to the denominator of the given expression

=> [62/75 - 0.16]. Here, we need to perform subtraction first as it comes before division in PEMDAS.

62/75 =  0.8266

Therefore, the denominator of the given expression becomes

=> [0.8266 - 0.16] = 0.6666

Now, let's simplify the numerator of the given expression. We have

=> [(3.5 + 4 2/3 + 2 2/15) / (0.5 * (1 1/20 + 4.1))].

Let's first convert all the mixed fractions to improper fractions.

3.5 can be written as 7/2, 4 2/3 can be written as 14/3, and 2 2/15 can be written as 32/15.

Therefore, the numerator becomes

=>  [(7/2 + 14/3 + 32/15) / (0.5 * (21/20 + 4.1))].

Let's first simplify the expression inside the brackets

=>  21/20 + 4.1 = 5.15.

Therefore, the numerator becomes

=>  [(7/2 + 14/3 + 32/15) / (0.5 * 5.15)].

Now, let's simplify the addition operation in the numerator. We need to find a common denominator to add the fractions.

The common denominator for 2, 3, and 15 is 30.

Therefore, (7/2 + 14/3 + 32/15) can be written as

=> (105/30 + 140/30 + 64/30).

Adding the fractions, we get (309/30).

Therefore, the numerator becomes [(309// (0.5 * 5.15)].

Next, let's simplify the expression inside the brackets - 0.5 * 5.15 = 2.575.

Therefore, the numerator becomes

[(309/30) / 2.575] = 3.68

Now that we have simplified the numerator and denominator of the given expression separately, we can simplify the entire expression.

[(8.99) / (0.6666)] / [3.68]

Let's first simplify the expression inside the first set of brackets.

(8.99) / (0.6666) = 13.486

Therefore, the given expression becomes 13.486 / 3.68 = 3.659

Answer:

Step-by-step explanation:

To calculate the weighted mean, first multiply each number by its corresponding weight, then add-up the products and divide by the sum of the weights-

weighted mean = (1 x 0.1 + 2 x 0.2 + 3 x 0.3 + 4 x 0.4) / (0.1 + 0.2 + 0.3 + 0.4)

Then simplifying the numerator:-

weighted mean = (0.1 + 0.4 + 0.9 + 1.6) / (0.1 + 0.2 + 0.3 + 0.4)

Then adding up the numerator:-

So the weighted mean of the numbers 1, 2, 3, and 4 with weights 0.1, 0.2, 0.3, and 0.4 respectively is 3.

There are 6 different possible arrangements as obtained using the factorial method and they are :

Here, we have,

If AC = BC

and, given that,

.A =(8x-40)

B =(5x - 1)

so, we have,

AC = BC i.e. ABC  is isosceles triangle.

so, the angle A & B are equal .

so, we get,

(8x-40)  = (5x - 1)

or, x = 39/3

Step-by-step explanation:

I’m sorry but I don’t know how I can solve you question

Answer:

I did the math in my head but please please trust me

It’s below

Step-by-step explanation:

C = 1 1/2

B = 2

A = 5

I’m going to try to explain as best as I can

First solve for C by subtracting the other numbers in its line going up to down from 9:

9 - 3 1/2 + 4 = C

9 - 7 1/2 = C

1 1/2 = C

now that w have C we can solve for b doing same steps:

9 - 5 1/2 + 1 1/2 = b

9 - 7 = b

2 = b

now we do A:

9 - 2 + 2 = a

9 - 4 = a

5 = a

Answer

A should be 5

B should be 2

c should be

[tex] 1\frac{1}{2 \\ } [/tex]

all should add up to 9

2+A(5)+b(2)= 9

a(5)+3 1/2+ 1/2=9

5 1/2+ b(2)+ 1 1/2= 9

3 1/2+ 1 1/2+ 4= 9

The acceleration of the car at that time was 3 m/s².

We have,

From the kinematic equation to find the acceleration:

v = u + at

where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.

Initial velocity u = 15 m/s

Final velocity v = 45 m/s,

Time t = 10 s

We can rearrange the equation to solve for acceleration:

a = (v - u) / t

Substituting the values, we get:

a = (45 m/s - 15 m/s) / 10 s

a = 3 m/s^2

Therefore,

The acceleration of the car at that time was 3 m/s².

The area inside the polar curve R = 2cos(3θ) for three full rotations is 6π.

The polar curve R = 2cos(3θ) is symmetric about the x-axis, with three petals that extend from θ = 0 to θ = π/3, π to 4π/3, and 5π/3 to 2π. To find the area inside the curve, we need to integrate the expression for the area element in polar coordinates over the desired region:

dA = (1/2) [tex]R^{2}[/tex] dθ

The limits of integration for θ are from α = -6π to β = 6π, since we want to find the total area inside the curve for three full rotations. Thus, the integral for the area is:

A = ∫(β=6π, α=-6π) (1/2) [tex]R^{2}[/tex]dθ

h is the height of the trunk

1 meter = 3.28084 feet

we can convert the given measurements from feet to meters to ensure consistent units.

The base diameter of the tree is 12.2 meters / 3.28084 = 3.719 meters,

If Farmer Johnson's minimum AVC is, for example, $1.50 per dozen eggs, then any price below $1.50 would result in losses that he could not sustain in the long run.

To determine the lowest price a dozen eggs could reach before Farmer Johnson would be forced to shut down in the short run, we need to know his minimum average variable cost (AVC) of producing eggs.

The average variable cost is the variable cost per unit of output, and it includes costs that vary with the level of production, such as labour, feed, and utilities.

If the price of a dozen eggs falls below the minimum AVC, Farmer Johnson will not be able to cover his variable costs and will incur losses. In the short run, he may continue to produce as long as he can cover his variable costs, but he will eventually be forced to shut down if he cannot cover his fixed costs as well.

Without information on Farmer Johnson's specific costs, we cannot determine the exact minimum AVC or the lowest price at which he would shut down. However, we can say that the lowest price a dozen eggs could reach before he would be forced to shut down is equal to his minimum AVC.
