The solution to the system of linear equation is:

x = 10 2/3, y = 5

The correct option is the last option   10 2/3, 5

From the question, we are to solve the given system of linear equation.

The given system of linear equations is

1/2x + 1/3y = 7

1/4x + 2/3y = 6

Multiply the first equation by 2

1/2x + 1/3y = 7      × 2

x + 2/3y = 14

Subtract the second equation from the resulting equation

     x + 2/3y = 14

- 1/4x + 2/3y = 6

--------------------------

3/4x = 8

Multiply both sides of the equation by 4/3

4/3 × 3/4x = 8 × 4/3

x = 32/3

x = 10 2/3

Substitute the value of x into

x + 2/3y = 14

To determine y

(10 2/3) + 2/3y = 14

32/3 + 2/3y = 14

Multiply through by 3

32 + 2y = 42

Subtract 32 from both sides

32 - 32 + 2y = 42 - 32

2y = 10

Divide both sides by 2

2y / 2 = 10 / 2

y = 5

Hence, the solution is:

x = 10 2/3, y = 5

The measurements of the cylindrical (round and hollow) drum that minimize the fetched of development are roughly 10.19 yards by 2.46 yards.

Let's expect that the round and hollow drum includes a stature of h and a span of r.

The volume of a barrel is given by: V = πr^2h.

We know that the drum includes a capacity of 806 cubic yards, so able to compose:

πr^2h = 806

We need to play down the taken a toll of building the drum, which is given by the entirety of the fetched of the beat, foot, and side divider.

The zone of the beat and foot of the drum is given by: A = πr^2.

The fetched of fabric for the beat and foot is $2 per square yard, so the taken a toll of the best and foot is:

C_topbottom = 2A = 2πr^2

The cost of fabric for the side divider is $17 per square yard, and the region of the side divider is given by:

A_side = 2πrh

The whole fetched of building the drum is in this manner:

C = C_topbottom + C_side = 2πr^2 + 17(2πrh) = 2πr^2 + 34πrh

Presently we are able utilize the condition for the volume of the drum to kill h from the fetched condition:

h = 806/(πr^2)

Substituting this expression for h into the taken a toll condition, we get:

C = 2πr^2 + 34πr(806/(πr^2)) = 2πr^2 + 27404/r

To discover the least fetched, we got to take the subordinate of the fetched condition with regard to r and set it rise to to zero:

dC/dr = 4πr - 27404/r^2 =

Fathoming for r, we get:

r = (27404/(4π))^(1/3) ≈ 10.19 yards

Substituting this esteem of r back into the expression for h, we get:

h = 806/(π(10.19)^2) ≈ 2.46 yards

Hence, the measurements of the round and hollow drum that minimize the fetched of development are roughly:

Span: 10.19 yards

Stature: 2.46 yards

First, you need to cancel out the 2 by subtracting 2 from both sides. Then, we divide both sides by -5. And finally, we remove the absolute value.

The interpretation of the slope and y-intercept of this equation is that: C. The slope predicts a temperature increases of about 1/6 for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 60 degrees.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical expression;

y = mx + c

Where:

Since Ronnie determined that the association between the number of chirps per minute (x) that crickets make at different temperatures (y) in degrees Fahrenheit is linear and that the line of best fit is given by;

The radius of the sphere with a volume of 10000 m³ is approximately 13.4 meters.

A sphere is simply a three-dimensional geometric object that is perfectly symmetrical in all directions.

The volume of a sphere is expressed as:

Volume =  (4/3)πr³

Where r is the radius of the sphere and π is the mathematical constant pi (approximately equal to 3.14).

Given that the volume of the sphere is 10000 m³, we can set up the equation:

Volume =  (4/3)πr³

r³ = Volume / (4/3)π

r = ∛( Volume / (4/3)π )

r = ∛( 10000/ ( (4/3) × 3.14) )

r = 13.4 m

The two triangles are congruent since they have equal angles and equal sides.

Congruent triangles are two triangles that have exactly the same size and shape.

In other words we can say that they have the same angles and the same side lengths.

So when two triangles are congruent, all of their corresponding parts including the angles and sides are equal.

For the given triangles

The missing value of angle C = 180 - (18 + 110) = 52⁰

The missing value of angle F = 180 - (18 + 52) = 110⁰

To find when the two equations 65x + 20 = y and 730 + 35x = y will meet on the graph, we need to solve for the value of x that satisfies both equations.

We can begin by setting the right-hand sides of the two equations equal to each other:

65x + 20 = 730 + 35x

Subtracting 35x from both sides, we get:

30x + 20 = 730

Subtracting 20 from both sides, we get:

30x = 710

Dividing both sides by 30, we get:

x = 23.67

Now that we have found the value of x that satisfies both equations, we can substitute it into either equation to find the corresponding value of y. Let's use the first equation:

y = 65x + 20

y = 65(23.67) + 20

y = 1539.55

Therefore, the two equations will meet on the graph at the point (23.67, 1539.55).

The cost of one small box of fruit and the cost of one large box of fruit is $11.5 and $14.5 respectively.

Let

cost of one small box of fruit = x

cost of one large box of fruit = y

15x + 15y = 390

20x + 25y = 592.50

From (1)

x + y = 26

x = 26 - y

Substitute x = 26 - y into (2)

20x + 25y = 592.50

20(26 - y) + 25y = 592.50

520 - 20y + 25y = 592.50

- 20y + 25y = 592.50 - 520

5y = 72.50

divide both sides by 5

y = 72.50/5

y = 14.5

Substitute y = 14.5 into

15x + 15y = 390

15x + 15(14.5) = 390

15x + 217.5 = 390

15x = 390 - 217.5

15x = 172.5

divide both sides by 15

x = 172.5/15

x = 11.5

Therefore, small box cost $11.5 and large box cost $14.5

Answer: f(n) = 2n - 2

Therefore, we can use this formula to find the value of f(n) for any positive integer n.

Step-by-step explanation: Using the given recursive formula:

f(1) = 0

f(n) = f(n-1) + 2

We can find the values of f(n) for different values of n:

f(1) = 0

f(2) = f(1) + 2 = 0 + 2 = 2

f(3) = f(2) + 2 = 2 + 2 = 4

f(4) = f(3) + 2 = 4 + 2 = 6

f(5) = f(4) + 2 = 6 + 2 = 8

And so on.

We can see that each term in the sequence is 2 more than the previous term. So, we can write the general formula for f(n) as:

f(n) = 2n - 2

Therefore, we can use this formula to find the value of f(n) for any positive integer n.

To install the gas riser in 10 days, a total number of 11 plumbers would be needed.

We can use the formula:

(number of workers) × (time) = (constant amount of work)

Let's let x be the number of plumbers needed to install the gas riser in 10 days. We can set up the equation:

(7 workers) × (15 days) = (x workers) × (10 days)

Simplifying the left side, we get:

105 worker-days = (x workers) × (10 days)

Dividing both sides by 10 days, we get:

10.5 workers = x

Since we can't have a fraction of a worker, we need to round up to the nearest whole number.

Therefore, we would need 11 plumbers to install the gas riser in 10 days.

The total area of all six sides that will be painted on the wooden cube is 96 square centimeters.

First, we need to understand that each cube has six faces or sides, which are all squares of the same size. When we paint the cube, we will be painting all six sides of it. Therefore, we need to find the total area of all six sides that will be painted.

To calculate the area of each side, we need to know the length of the side. You mentioned that the wooden blocks are cubes, so each side will have the same length. Let's say the length of each side is 4 cm.

Now, we can calculate the area of one side of the cube by squaring the length of the side. In this case, the area of one side will be:

Area of one side = (length of side)²

= (4 cm)²

= 16 cm²

Since there are six sides to each cube, we can find the total area of all six sides by multiplying the area of one side by six:

Total painted area = 6 x Area of one side
