What is the value of y at which the lines 6x + 2y =30 and y =0.5x+1 intersect?

This line plot shows the measurements of cars and trucks in half-inch increments from 3 inches to 12 inches.

A line plot, also known as a dot plot or a dot chart, is a simple graph that displays data along a number line. In a line plot, each data point is represented by a dot or other symbol above its location on the number line. The dots are used to indicate the frequency or number of times each value occurs in the data set. Line plots are often used to display small to moderate-sized data sets and are especially useful for displaying categorical or discrete data. They are simple to create and interpret, making them a popular tool in data analysis and visualization.

Here,

A line plot is a graph that displays data along a number line, with X's or other marks above each value to indicate how many times it appears in the data set. To create a line plot from the measurements of the cars and trucks, you would follow these steps:

Choose a scale for the number line that includes all the measurements. For example, you could use a scale where each unit represents 1 inch, and the number line goes from 0 to 12 inches.

Make a dot for each measurement at the corresponding location on the number line. For example, if a car measures 5.5 inches, you would make a dot above the number 5.5 on the number line.

Repeat step 2 for each measurement, placing each dot above the corresponding value on the number line.

Count the number of dots above each value on the number line and make an X or other mark above the corresponding value to indicate how many times it appears in the data set.

Connect the X's or marks above each value to create a line that shows the frequency of each measurement.

Here is an example of what the completed line plot might look like:

The Answer Is 360

Step-by-step explanation:

Why Because If you Take 45 and 5 it is 9 Then Take 9 and Multiply 9 by 40 which takes you to 360

Answer:

The height of the building is 360 ft.

Step-by-step explanation:

Assuming the two given right triangles are similar, their corresponding sides will be the same ratio.  

Therefore, the ratio of height to base of the triangles is:

To calculate the height of the building, solve the ratio for x.

[tex]\implies x:45=40:5[/tex]

[tex]\implies \dfrac{x}{45}=\dfrac{40}{5}[/tex]

[tex]\implies \dfrac{x}{45}=8[/tex]

[tex]\implies \dfrac{x}{45}\cdot 45=8 \cdot 45[/tex]

[tex]\implies x=360\; \sf ft[/tex]

Therefore, the height of the building is 360 ft.

Inequalities has no solution is -4|s-20| < - 16, So correct option is A.

Inequality is a mathematical statement that describes the relationship between two expressions that are not necessarily equal. It is used to compare two quantities or values, indicating which one is greater than, less than, or equal to the other. Inequalities can be expressed using symbols such as < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), and ≠ (not equal to).

For example, the inequality 3x < 15 compares the variable x to the constant 5, indicating that x is less than 5. This inequality can be solved by dividing both sides by 3 to obtain x < 5. Similarly, the inequality 2y + 4 ≥ 10 compares the variable y to the constant 3, indicating that y is greater than or equal to 3. This inequality can be solved by subtracting 4 from both sides and then dividing by 2 to obtain y ≥ 3.

The correct option is:

O-4|s-20| < - 16

To solve this inequality, first, we isolate the absolute value:

-4|s-20| < -16

Dividing both sides by -4 and flipping the inequality sign:

|s-20| > 4

Now we need to solve two inequalities:

s-20 > 4 and s-20 < -4

Simplifying each:

s > 24 and s < 16

These two inequalities cannot be true at the same time. Therefore, there is no solution to the original inequality.

The correct expression to calculate the acceleration of the robot is (a)0.14N / 12kg, which is approximately equal to 0.012 m/s^2.

To calculate the acceleration of the robot, we need to use the formula F = ma, where F is the net force applied, m is the mass of the robot, and a is the acceleration.

We know that the net force applied by the engine is 0.14N. To use this value in the formula, we need to convert it into the standard unit of force, which is Newtons (N). We also know that the mass of the robot is 12kg.

The correct expression to calculate the acceleration of the robot is option A, which is:

0.14N / 12kg

This expression represents the force per unit mass, which is the definition of acceleration. By dividing the net force of 0.14N by the mass of 12kg, we get the acceleration of the robot in m/s^2.

Option B is incorrect because it multiplies the mass and force, which does not give us the acceleration. Option C is incorrect because it adds the mass and force, which is not a valid operation. Option D is incorrect because it calculates the acceleration based on the distance traveled, which is not directly related to the force and mass of the robot.

In conclusion, the correct expression to calculate the acceleration of the robot is 0.14N / 12kg, which is approximately equal to 0.012 m/s^2.

The surface area of the pyramid is 1,495,368 square feet (approximate)

A pyramid is a three-dimensional shape with a triangular base and faces that meet at a single point, or apex, and are each made of three triangles.

To find the surface area of the Great Pyramid of Giza, we need to calculate the area of each face and add them together.

The base of the pyramid is 756 feet. then, the area of square-base is:

756 feet × 756 feet ⇒ 571,536 square feet

The height of the pyramid is 480.6 feet. Using the Pythagorean theorem, we can find the slant height of the pyramid:

slant height = [tex]\sqrt{height^2 + (\frac{ base}{2}) ^2}[/tex]

slant height = [tex]\sqrt{480.6^2 + (\frac{756}{2})^{2}[/tex]

slant height = 611 feet (approx.)

Each triangular face has a base of 756 feet and a height of 611 feet. So, the area of each triangular face is:

(1/2) x 756 feet x 611 feet = 230,958 square feet

There are four triangular faces, so the total area of the four faces is:

4 x 230,958 square feet = 923,832 square feet

The total surface area of the pyramid is the sum of the area of the square base and the area of the four triangular faces:

571,536 square feet + 923,832 square feet = 1,495,368 square feet

Therefore, the surface area of the Great Pyramid of Giza is approximately 1,495,368 square feet.

Answer:

  ST = 32

Step-by-step explanation:

Given circle U with tangents PQ = 4x+2 and QR = 7x-19 and segment QU = 34, you want the length of diameter ST.

The two tangents are the same length, so ...

  QR = PQ

  7x -19 = 4x +2

  3x = 21 . . . . . . . . add 19-4x

  x = 7 . . . . . . . . divide by 3

The length of tangent PQ is ...

 PQ = 4x +2 = 4(7) +2 = 30

Triangle QPU is a right triangle with leg PQ = 30 and hypotenuse QU = 34. Then the length of radius PU is found using the Pythagorean theorem:

  PU² + PQ² = QU²

  PU² = QU² - PQ² = 34² -30² = 256

  PU = √256 = 16 . . . . . radius of the circle

The diameter ST of the circle is twice the length of the radius:

  ST = 2·PU = 2·16

  ST = 32

You may recognize the right triangle as having sides that are the Pythagorean triple {8, 15, 17} multiplied by 2. The lengths 30 and 34 give you the clue.

The daily percentage rate (DPR) for the given Annual Percentage Rate (APR) on credit card is 17.8% is equal to 0.048%.

Given the Annual Percentage Rate (APR) on credit card is 17.8%.

Now, we need to find the daily percentage rate (DPR) for the given yearly percentage on credit card.

To find your current annual percentage rate, look at your monthly statements. To determine the daily percentage rate (DPR), divide the annual percentage rate (APR) by 365 (the number of days in a year).

So, given APR = 17.8%

Now, daily percentage rate will be:

⇒ Daily percentage rate = Annual Percentage Rate ÷ 365

⇒ DPR = APR / 365

⇒ DPR = 17.8% ÷ 365

⇒ DPR = 0.048%

Therefore, daily percentage rate (DPR) is equal to 0.048%.

Answer:

the side of the square is approximately 8.29 meters.

Answer:

To simplify (4x^2)/(7y^2) and (21y^3)/(20x^4), we need to simplify each fraction separately.

(4x^2)/(7y^2) can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 1:

(4x^2)/(7y^2) = 4x^2/7y^2

(21y^3)/(20x^4) can also be simplified by dividing both the numerator and denominator by their greatest common factor, which is 1:

(21y^3)/(20x^4) = 21y^3/20x^4

So the simplified fractions are 4x^2/7y^2 and 21y^3/20x^4, respectively.

Using percentages we know that 143 patients out of 238 are in need to take the inoculation.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.

If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The proportion, therefore, refers to a component per hundred.

Per 100 is what the word percent means. The letter "%" stands for it.

So, the number of patients is:

238

The percentage of patients that needs inoculation:

0.6 which is 60

Now, calculate:

= 238/100 * 60

= 142.8
Rounding off: 143

Therefore, using percentages we know that 143 patients out of 238 are in need to take the inoculation.

What is transformation?

A point, line, or geometric figure can be transformed in four different ways, each of which alters the shape and/or placement of the object.

Although Image refers to the position and ultimate shape of the object, Pre-Image refers to the shape of the thing as it was before alteration.

We are given coordinate axis with two figures ABCD and EFGH.

In order to map the figures, we can reflect the figure across y - axis first and then across x - axis. This transformation will map the figure.

5 1/5 - 3 7/10 simplified and subtracted equals 3/2.

what is improper fraction?

An improper fraction is a fraction in which the numerator (the top number) is greater than or equal to the denominator (the bottom number). For example, 7/4 is an improper fraction because the numerator (7) is greater than the denominator (4).

To make 5 1/5 - 3 7/10 a simpler problem, we need to convert the mixed numbers into improper fractions, which will make it easier to subtract them.

To convert a mixed number to an improper fraction, we need to multiply the whole number by the denominator of the fraction and then add the numerator.

So, we have:

5 1/5 = (5 x 5 + 1)/5 = 26/5

3 7/10 = (3 x 10 + 7)/10 = 37/10

Now, we can subtract the two improper fractions:

26/5 - 37/10

To subtract fractions, we need to have a common denominator. The smallest number that both 5 and 10 divide into is 10, so we can convert both fractions to have a denominator of 10:

(26/5) x (2/2) = 52/10

37/10

Now we can subtract the fractions:

52/10 - 37/10 = 15/10

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 5:

15/10 = (15/5) / (10/5) = 3/2

Therefore, 5 1/5 - 3 7/10 simplified and subtracted equals 3/2 or 1 1/2.
