By dividing the width and height by the dpi, one may get the pixel size. Additionally, a digital camera will have pixel dimensions, which are the sum of its resolution's horizontal and vertical pixel counts (e.g., 2,048 by 3,072), this is the formula to calculate pixel.

The smallest component of a visual display or digital image is a pixel, also known as a picture element. A grid of pixels is used to create computer screens. Red, blue, and green illumination components make up each pixel, which may produce millions of distinct colors by combining them in various ways and at various intensities.

For instance, a computer with a display resolution of 1280 x 768 will create up to 98,3040 pixels on a display screen. The number of pixels per inch of the monitor screen affects image quality; more pixels per inch produce better images.

100% percent of the espressos were single-shot.

What is the percentage?

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios, proportions, and rates. It is denoted by the symbol "%". For example, if you have 25 out of 100 items, you can express this as 25% to represent the proportion of items that you have.

The total number of espressos sold yesterday afternoon was 5. If 5 of them were single-shot, then 100% * 5 / 5 = 100% of the espressos were single-shot.

Hence, 100% percent of the espressos were single-shot.

The correct option for the area of the circle is B. 3,419.46 cm².

The area of a circle is π multiplied by the square of the radius. The area of a circle(A) when the radius 'r' is given is πr².

Area of circle = πr²

π = 3.14

radius = diameter/2

radius of the circle = 66 cm/2

radius of the circle = 33 cm

Area of the circle = 3.14 × (33 cm)²

Area of the circle = 3.14 × 1089 cm²

Area of the circle = 3419.46 cm²

Therefore, the area of the circle measured by Jon and Becky is equal to 3,419.46 cm².

Answer:

The first number is 4, the second is 3

Step-by-step explanation:

We can make 2 equations, let x be the first number, and y be the second number.

x = 3y - 5

4x - 2y = 10

We sub x = 3y - 5

=> 4(3y - 5) - 2y = 10

=> 12y - 20 - 2y = 10

=> 10y - 20 = 10

=> 10y = 30

=> y = 3

Sub y = 3 into x = 3y - 5

x = 3(3) - 5

x = 4

Therefore, the first number is 4, and the second is 3

Mark the sides BC and DF as congruent.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.

This characteristic is known as the triangle's angle sum property.

If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.

In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.

A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.

The vertex is the intersection of two straight lines. The triangle therefore has three vertices.

According to our question-

We are given a side and an adjacent angle, and we must figure out which side or angle is needed in order for SAS to provide proof.

Answer: To find the percent of gas used, we need to divide the amount of gas used by the total amount of gas the van can hold and multiply by 100.

Percent of gas used = (Gas used / Total gas) * 100

Given that the van uses 8.4 gallons of gas and can hold 14 gallons of gas, we can substitute these values into the formula:

Percent of gas used = (8.4 / 14) * 100

By performing this calculation we can get that the percent of gas used was: 8.4/14 = 0.6 = 60%

So, 60% of the total gas was used during the trip to the Seattle Zoo.

Step-by-step explanation:

Answer:

60%

Step-by-step explanation:

8.4 divided by 14 = 0.6. Let 1 be the 100%. Since 0.6 is the same as 0.60, we remove the decimal and make it 60.

On solving the provided question we can say that the radius of circle is 2.1415 cm.

Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

We know, Central angle (θ) = (length arc)/radius ….(1)

Convert angle in radian:

Angle in radians = Angle in degrees x π/180° = 197° x π/180 = 1.09

From (1),

Radius = (length arc)/Central angle

= 8/3.1415 =2.1415cm

Therefore radius is 2.1415 cm.

For the given quadratic equation, the solutions are x = -3 and x = -3.

What is the completing square method?

The completing the square method is a technique used to solve quadratic equations of the form y = ax² + bx + c. The goal of this method is to convert the equation into the standard form of a quadratic equation, which is y = a(x + h)² + k, where a, h and k are constants.

To solve y = x² + 6x + 8 by completing the square, we need to add and subtract a value to the equation so that the x-term (x² + 6x) is a perfect square. In this case, we need to add and subtract (6/2)² = 9 to the equation, which gives us:

y = x² + 6x + 8

y = (x² + 6x + 9) - 1

Now, we can take the square root of the x-term, which is (x + 3)², and we get:

y = (x + 3)² - 1

The equation is now in the standard form of a quadratic equation, with y = (x + 3)² - 1. We can now solve for x by taking the square root of both sides of the equation and getting x = -3, -3 .

Alternatively, We can also solve for x by factoring the expression inside the square, which would give (x + 3) (x + 3) = 0 and x = -3, -3

Hence, for the given quadratic equation, the solutions are x = -3 and x = -3.

The ratio of a circle can be found through the formula A = πr2, where A is the area of the circle and r is the radius of the circle.

To find the ratio of a circle, you must first calculate the area of the circle. To calculate the area, multiply the value of π (3.14159) by the square of the radius (r2). For example, if the radius of the circle is 4, the area of the circle would be 3.14159 x 42, which is equal to 50.2653. The ratio of a given circle can then be found by dividing the area of the circle (50.2653) by the square of the radius (42), which gives 1.273.

The majority of the data is split to the right and left of the mean.

The data is mostly divided to the right and left of the mean. The normal distribution is symmetric and continuous. Positively skewed data will have a higher mean than the median. If the data distribution is tilted to the left, the mean is less than the median, which is frequently less than the mode. A probability function that defines how the values of a variable are distributed is known as the normal distribution. The mean, median, and mode values in a normal distribution are all equal. So, in the context of a normal distribution curve, point (ii) is valid.
