y represent the total charge (dependent variable) and x represent the number of people (independent variable)

The rate of change is $7.75 per person while the initial value is $20.

The total charge for 17 people is $151.75

An equation is an expression that shows how two numbers and variables are related using mathematical operations such as addition, subtraction, exponent, division and multiplication.

Let y represent the total charge (dependent variable) and x represent the number of people (independent variable)

Hence:

y = mx + b

where m is the rate of change and b is the initial value

Jimmy is told the total charge for 10 people, including himself, would be $97.50, hence:

97.5 = 10m + b    (1)

Also, the total charge for 20 people, including himself, would be $175, hence:

175 = 20m + b    (2)

From both equations:

m = 7.75 and b = 20

The rate of change is $7.75 per person while the initial value is $20.

y = 7.75x + 20

For 17 people:

y = 7.75(17) + 20 = 151.75

The total charge for 17 people is $151.75

Experimental probability of tails = Number of tails / Total number of tosses

Experimental probability of tails = 287 / 500

Experimental probability of tails = 0.574 or 57.4%

Since the experimental probability of getting tails is greater than the theoretical probability, this suggests that the coin may be biased toward tails.

The scale factοr frοm shape A tο shape B is 8

Shapes in variοus dimensiοns can be scaled using the Scale Factοr. In geοmetry, we study many geοmetrical fοrms that exist in bοth twο- and three-dimensiοns. The scale factοr is a way tο cοmpare figures with similar appearances but differing scales οr measurements. Cοnsider twο circles that resemble οne anοther but may have different radii.

The scale factοr οf a shape refers tο the amοunt by which it is increased οr shrunk. It is applied when a 2D shape, such as a circle, triangle, square, οr rectangle, needs tο be made larger.

The total resistance of the circuit is 0.051 ohms.

A circuit's opposition to current flow is measured by its resistance. The Greek letter omega stands for ohms, which are used to measure resistance. German physicist Georg Simon Ohm (1784–1854), who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance known as an ohm. He is credited for coming up with Ohm's Law.

The resistors in series is given as:

R = R2 + R5 + R8

R = 8 + 18 + 14

R = 40

Also, Req = R4 + R6

Req = 7 + 3 = 10

Now, the resistors R and Req are in parallel connection.

Thus,

Rp = 10 + 40 / (10)(40)

Rp = 50/400 = 0.125

Now, R1, Rp, and R7 are in series:

R = 10 + 0.125 + 12

R = 22.125

Again, R3 and R are in parallel:

R = 22.125 + 150 / (22.125)(150)

R = 0.051

Hence, the total resistance of the circuit is 0.051 ohms.

For given linear equations, a. x cannot equal -1 or -3, c. x = -2 + 2 √(2) and x = -2 - 2√(2).

What is a linear equation ?

A linear equation is an equation of a straight line, which can be written in the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept (the point where the line crosses the y-axis). Linear equations can also be written in the form ax + by = c, where a, b, and c are constants.

Now,

a. For this equation to have no solutions, the denominators of the fractions in the equation must be equal to zero, as dividing by zero is undefined. Therefore, x cannot equal -1 or -3. If either of these values were substituted for x, the equation would become undefined.

b. Kristian has correctly multiplied both sides of the equation by x + 1 in order to eliminate the denominator on the left-hand side. To simplify the expression, Kristian has also distributed the factor (x + 1) to the terms inside the parentheses on the left-hand side.

c. Continuing from Kristian's work, we have:

x + 2 + (3x + 15)/(2x + 7) = 3x + 3

Multiplying both sides by the denominator 2x + 7 to eliminate the fraction, we get:

(2x + 7)(x + 2) + 3x + 15 = 3x + 3(2x + 7)

Expanding the parentheses and simplifying, we get:

2x² + 11x + 14 + 3x + 15 = 6x + 21

2x² + 14x - 6x + 29 = 6x + 21

2x² + 8x - 8 = 0

Dividing both sides by 2, we get:

x² + 4x - 4 = 0

Using the quadratic formula, we get:

x = (-4 ± √(16 + 16)) / 2

x = -2 ± 2√(2)

Therefore,

                the solutions to the original equation are x = -2 + 2√(2) and x = -2 - 2√(2).

The equation of the line perpendicular to PQ passing through Z is:

y - ZY = 21/29(x - ZX)

To solve this problem, we can use the fact that the centroid of a triangle divides each median into two segments, where the length of the segment adjacent to the vertex is twice the length of the other segment.

Let M be the midpoint of WY, N be the midpoint of WX, and Z be the centroid of triangle WXY. Then, we know that:

WM = MY

WN = NX

ZM = 2ZC

ZN = 2ZB

where ZB and ZC are the lengths of the segments of the median from vertex W that intersect XY at points B and C, respectively.

We can use this information to set up a system of equations:

WM + WN = WY

ZM + ZN = ZW

ZC + ZB = ZX

Substituting the given values, we have:

(87/2) + (39/2) = WY

2ZC + 2ZB = WZ

48 + (87/2) = ZX

Simplifying each equation, we get:

WY = 63

ZC + ZB = WZ/2

ZX = 141

Now, we can use the fact that the sum of the lengths of the medians of a triangle is equal to three times the length of the segment connecting the centroid to the circumcenter. That is:

WX + WY + WZ = 3 × ZO

where O is the circumcenter of triangle WXY.

Substituting the given values and the values we found earlier, we have:

WX + 63 + 141 = 3 * ZO

Simplifying, we get:

WX = 3ZO - 204

To solve for WX, we need to find ZO. We know that the circumcenter is the intersection of the perpendicular bisectors of the sides of the triangle. Let P be the intersection of the perpendicular bisectors of WY and WX, and Q be the intersection of the perpendicular bisectors of WY and XY. Then, ZO is the distance from Z to the line PQ.

We can find the equation of PQ by finding the midpoint of WY and WX, which is M. Then, the slope of PQ is the negative reciprocal of the slope of the line passing through M and Z.

We know that the slope of the line passing through M and Z is:

(ZM - MY) / (ZW - WM) = (2ZC - MY) / (WZ - WM)

Substituting the given values and the values we found earlier, we have:

(2ZC - 63/2) / (141/2 - 87/2) = (2ZC - 63/2) / 27

Solving for ZC, we get:

ZC = 117/2

Now, we can find the equation of PQ. The midpoint of WY is (0, 63/2), and the midpoint of WX is (87/2, 0). Therefore, the slope of PQ is:

(-87/2) / (63/2) = -29/21

The equation of PQ is therefore:

y - 63/2 = (-29/21)(x - 87/2)

Simplifying, we get:

29x + 21y = 1911

To find ZO, we need to find the distance from Z to the line PQ. We know that the equation of the line perpendicular to PQ passing through Z is:

y - ZY = 21/29(x - ZX)

Therefore , the solution of the given problem of triangle comes out to be GA equals 18.

Due to its two or more additional parts, a shape is a hexagon. It has a straightforward rectangle shape. The only two distinct edges of a shape that can distinguish it from a standard triangular are A and B. Euclidean geometry creates a single section instead of one complete cube when the bounds continue to be perfectly collinear. A triangular has three sides and three angles.

Here,

A midsegment in a triangle links the middles of the other two sides and runs parallel to the third side. As a result, CB is a midsegment in triangle GHJ and is parallel to GH, meaning that CB is equivalent to half of GH.

We thus have:

=>  CB = 1/2 GH

=>  5x+3 = 1/2 (9x+9)

=>  10x + 6 = 9x + 9

=> x = 3

With the knowledge of x, we can locate GH and GA:

=>  GH = 9x+9 = 9(3)+9 = 36

=> GA = 1/2 GH = 1/2 (36) = 18

GA therefore equals 18.

A cylinder is also defined as an infinitely curved surface in several modern domains of geometry and topology. A "cylinder" is a three-dimensional object composed of curved surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure with two bases that are both identical circles linked by a curving surface at the height of the cylinder, which is defined by the distance between the bases from the Centre. Cold beverage cans and toilet paper wicks are two examples of cylinders.  

V = r2h, where r is the radius and h is the height, gives the volume of a cylinder.

Because the radius is 5 cm and the height is 10 cm in this situation, the volume of the cylinder is:

V = π(5 cm) (5 cm)

²(10 cm) = 785.4 cm³

Because the vinegar entirely fills the cylinder, its volume equals the cylinder's volume. We may calculate the mass of vinegar using its density:

density Equals mass divided by volume

density x volume Equals mass

1.05 g/cm3 x 785.4 cm3 = mass

The equations consists of the sum of the dividends in the rectangle, divided by 9 on the left-hand side (LHS) of the equation, while on the right-hand side consists of the dividends in the rectangles, each divided by 9

The second line of the equation consists of the quotients on top of the rectangle, which are 30 and 6

The third line consists of the sum of the quotient, which is 30 + 6 = 36

Therefore, we get;

((270 + 54) = 324)  ÷ 9 = 270 ÷ 9 + 54 ÷ 9

= 30 + 6

= 36
