Step-by-step explanation:

Solving for x:

[tex]-10=xy+z[/tex]

Subtracting z from both sides:

[tex]-10-z=xy[/tex]

Divding both sides by y:

[tex]\displaystyle \frac{-10-z}{y} =x[/tex]

Solving for j:

[tex]\displaystyle h-\frac{4}{j} =k[/tex]

Subtracting h from both sides:

[tex]\displaystyle - \frac{4}{j} =-h+k[/tex]

Multiplying both sides by j,

then dividing both sides by (-h + k):

[tex]\displaystyle - \frac{4}{-h+k} =j[/tex]

Simplifying the equation:

[tex]\displaystyle \frac{4}{-(-h+k)} =j[/tex]

[tex]\displaystyle \frac{4}{h-k} =j[/tex]

[tex]\$10x + \$94\geq\ \$194[/tex]

Step-by-step explanation:

Given

Wage = $10 per hour

Savings = $94

Stereo = $194

Required

Represent the scenario using an inequality

From the question, x represents the number of hours.

If his wage is $10 per hour then, his wage is $10x in x hours

Solving further;

For George to afford the stereo, the sum of his wages and savings must be greater than or equal to the cost of the stereo

Mathematically, this is:

[tex]Wages + Savings \geq\ Stereo[/tex]

Substitute right values for the above expression

[tex]\$10x + \$94\geq\ \$194[/tex]

The options are not well presented, hwever the solution is [tex]\$10x + \$94\geq\ \$194[/tex]

Answer:

Step-by-step explanation:

3x + 2y - z = 8

-3x + 4y + 5z = -14

6y + 4z = -6

3x + 2y - z = 8

-3x + 9y - 12z = 42

11y - 13z = 50

6y + 4z = -6

66y  - 78z = 300

-66y - 44z =  66

-122z = 366

z = -3

3x + 2y + 3 = 8

3x + 2y = 5

-3x + 4y -15 = -14

-3x + 4y = 1

3x + 2y = 5

-3x + 4y = 1

6y = 6

y = 1

3x + 2 + 3 = 8

3x + 5 = 8

3x = 3

x = 1

x=1, y = 1, z = -3

Answer:

  3π

Step-by-step explanation:

Arc length is given in terms of central angle θ in radians as ...

  s = rθ

For r = 27 and θ = (20/180)π, the arc length is ...

  s = (27)(20/180)π = 3π

The arc length is 3π units.

Based on the figure, the statements that are true are

That is, the first, second and fifth statements.

From the image, we will determine the statements that are true based on the figure.

For the first statement -  SV is perpendicular to TP

From the figure,

SV is a line intersecting plane A at point P, at right angle. That is, SV is perpendicular to point P. Then, SV is perpendicular to plane A since point P lies on the plane.

Also, P lies on the plane (plane A); then we can infer that TP is parallel to plane A since point T also lie on the plane (plane A).

Since, SV is perpendicular to the plane, then SV is also perpendicular to TP.

∴ The statement (SV is perpendicular to TP) is true

For the second statement - SV is perpendicular to plane A

As stated above, SV is perpendicular to point P. Since point P lies on the plane (plane A), then SV is perpendicular to plane A.

∴ The statement (SV is perpendicular to plane A) is true

For the third statement - points S, P and Q are collinear

Collinear points are points that lie on the same line.

Points S, P and Q are not collinear because, a single line cannot pass through the three points, that is, the points (S, P, and Q) do not lie on a single line.

∴ The statement (points S, P and Q are collinear) is NOT true

(From the image, an example of points that are collinear are points S, P, and V)

For the fourth statement - points R, T, and U are collinear

As explained above, points R, T, and U are not collinear because, a single line cannot pass through the three points, that is, the points (R, T, and U) do not lie on a single line.

∴ The statement (points R, T and U are collinear) is NOT true

NOTE: (The points only lie in the same plane (plane A), that is, they are coplanar)

For the fifth statement - point P lies on SV and in plane A

Since line SV intersects plane A at point P, that means point P lies in plane A. Also point P lies on line SV since it is on the line as shown in the image.

∴ The statement (point P lies on SV and in plane A) is true

For the sixth statement - points U, S, V, and Q are coplanar

Points or lines are said to be coplanar if they lie in the same plane.

Of the given points, only point U lies in plane A. Points S, V, and Q do not lie in the same plane and as well do not lie in the same plane as point U.

∴ The statement (points U, S, V, and Q are coplanar) is NOT true.

(From the image, an example of points that are coplanar are points U,P,R, and T because they lie on the same plane).

Hence, based on the figure, the statements that are true are the first, second and fifth statements. that is

Answer:

40

Step-by-step explanation:

Variability is a measures of the interquartile range of a given set of data. The greater the interquartile range, the more the variability.

The interquartile range (IQR) = Third quartile (Q3) - First Quartile (Q1)

IQR for City A = 70 - 40 = 30

IQR for City B = 80 - 40 = 40.

City B has a greater IQR value, therefore, it has the greater variability in temperature.

The interquartile range for the city with greater variability is 40.

Answer:

About 66 tubes

Step-by-step explanation:

Cylinder surface area formula: 2πr(h + r) where h = height and r = radius

In this case, h = 14, π = 3.14 and r = 4.5 so the surface area of one pottery is:

2 * π * 4.5 * (14 + 4.5) = 166.5π ≈ 523.08

The surface area of 15 potteries would be 523.08 * 15 = 7846.2 so it would take 7846.2 / 120 = 65.385 ≈ 66 tubes. We round to the nearest integer because in this context, you can only have integer values of tubes, you can't have, say, 0.5 tubes.

Answer: 2/23

Step-by-step explanation: Absolute value is a term which is used to indicate the distance of a point or number from the origin of a number line or coordinate system.

Suppose x is a real number. Then the absolute value of x is defined as follows:

For x = 0 or x > 0, | x | = x

For x < 0, | x | = - x

Now, we have to find the absolute value of the given number  that means we have to find the distance of   from the origin of a number line.

Distance of  from the origin is  . As distance can never be negative.

Therefore, the absolute value of  is 2/23 .

Answer:

d = 13  (distance between two points)

Step-by-step explanation:

(4, -2) and (-1, 10)

(X1, Y1)  and (X2, y2)

distance between two points = d = sqrt (X2 - X1)² + (Y2 - Y1)²

d = √ (-1 - 4)² + (10 - (-2))²

d = √25 + 144

d = √169

d = 13  (distance between two points)

Answer:

Length = 42 feet

Width = 21 feet

Step-by-step explanation:

Let the length and width be represented by L and W

L = 2W

Perimeter (P) = 126 feet

2(L + W) = 126

L + W = 126/2 = 63

2W + W = 63

3W = 63

W = 63/3 = 21 feet

L = 2W = 2 × 21 feet = 42 feet

Answer:

9465 people/square mile.

Step-by-step explanation:

If there are  646,449 people in 68.3 square miles for the district of columbia, the unit rate in terms of people per square mile for the District of Columbia will be expressed as shown;

646,449 people = 68.3 square miles

x people = 1 square mile

Cross multiply

646,449 people *  1 square mile = 68.3 square miles * x people

x = 646,449 people *  1 square mile/68.3 square miles

x = 646,449/68.3 square miles

x =  9464.8463 square miles

x ≈ 9465 people/square mile.

Hence the unit rate in terms of people per square mile for the District of Columbia is approximately 9465 people.
