How do you write greater than 4?.

Answers

To show that one value is greater than another, use the "greater than" symbol (>). It can be used to express a comparison between two values in mathematical operations, programming, and other forms of notation.

   For instance, the "greater than" symbol can be used to compare integers in mathematical operations. For instance, you would write "x > y" to indicate that x is greater than y. This can alternatively be understood as "x exceeds y."

  Other comparison symbols, such as "less than," "greater than," and "less than or equal to," can be used in addition to the "greater than" symbol. These symbols can be used to describe many forms of value comparisons in programming and mathematical processes.

  The word "greater than" is represented by the symbol ">," therefore to write "greater than 4" you would write ">4".

Answers

Julio needs to prove that two sides of the two triangles are congruent, in addition to the hypotenuse and one set of legs that are already congruent, to use the SAS Triangle Congruence Theorem.

Julio needs to prove that the two triangles have congruent sides in order to use the SAS Triangle Congruence Theorem. This means that he needs to show that one side of one triangle is congruent to a corresponding side of the other triangle and the same applies to the other two sides. This can be done by using methods such as measuring the sides, using algebraic equations, or using geometric constructions.

According to Julio statement, he has already constructed two right triangles to have congruent hypotenuses and one set of congruent legs, which means he has already proved that one side of one triangle is congruent to a corresponding side of the other triangle (hypotenuse) and one set of legs are congruent.

Therefore, Julio need to prove the remaining side of the triangle congruent to the corresponding side of the other triangle. Once he proves this, he can use the SAS Triangle Congruence Theorem to state that the two triangles are congruent.

Let X = the number of spins until Marshall wins a prize.


What is the probability that Marshall wins a prize on his 2nd spin?


Recall: P(X = k) = (1 – p)k–1p


Round to 4 decimal places

Answers

The probability that Marshall wins a prize on his second spin =  0.1875

Consider an event X = the number of spins until Marshall wins a prize.

Given that a prize wheel with 4 segments of equal size, one of which is labeled winner.

So, the sample space n = 4

For given event x, the possible outcomes = 1

Using the formula of probability,

p = x/n

p = 1/4

p = 0.25

So, the probability of success p = 0.25

q = 1 - p

q = 1 - 0.25

q = 0.75

To find the probability that Marshall wins a prize on his 2nd spin.

Using formula, [tex]P(X = k) = (1 - p)^{k-1}p[/tex]

For  k = 2,

[tex]P(X = 2) = (1 - 0.25)^{2-1}\times 0.25[/tex]

P(X = 2) = 0.75 × 0.25

P(X = 2) = 0.1875

The length x will be 23.994615468 ft or rounded approximately 24 feet.

Roof Length Calculation in Feet

The length x is the distance from the center of the roof to the edge of the roof.

Using trigonometry, we can find the length x by using the equation:

        x = 15 + (15 * tan(25°)) + 1

The tan(25°) can be found using a calculator or table. With a calculator, we get:

        tan(25°) = 0.466307658

Substituting this value back into the equation, we get:

        x = 15 + (15 * 0.466307658) + 1

        x = 15 + 6.994615468 + 1

        x = 23.994615468 ft

So, the length x = 23.994615468 ft, or approximately 24 feet.

The problem is about finding the length x, which is the distance from the center of the roof to the edge of the roof of a grain bin with a radius of 15 ft and a recommended slant of 25° for the roof.

What is the relationship between the sine rule and the sine ratio in a right triangle?.

Answers

The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.

What is the relationship between the sine rule and the sine ratio in a right triangle?.

The law of sines relates the ratios of side lengths of triangles to their respective opposite angles. This ratio remains equal for all three sides and opposite angles. We can therefore apply the sine rule to find the missing angle or side of any triangle using the requisite known data.

The ratio of the side and the corresponding angle of a triangle is equal to the diameter of the circumcircle of the triangle. The sine law is can therefore be given as,

[tex]\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}[/tex]

In a right triangle, the sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.

At KFC, the kitchen taff baked 25 chicken leg and 50 wing. The taff had to prepare platter for an office lunch. If each platter will have the ame number of leg and wing, what i the greatet number of platter they can make?

Answers

So, each platter will have 25 legs and 25 wings.

To determine the greatest number of platters the kitchen staff can make, you need to find the least common multiple of 25 and 50. This is because each platter must have the same number of legs and wings, so you need to find the smallest number of legs and wings that can be divided evenly into both 25 legs and 50 wings.

The least common multiple (LCM) of 25 and 50 is 50. This means that the greatest number of platters the kitchen staff can make is 50/25 = 2 platters.

Therefore, each platter will have 25 legs and 25 wings.

A triangular tract of farm land has sides of length 2.1 miles, 1.8
miles, and 2.7 miles. If a bag of fertilizer covers 0.2 square
miles, how many bags of fertilizer are needed to cover the area
of the triangle? Round your answer to the nearest whole
number. NEED THIS ASAP TYSM

Answers

Answer: we would need 7 bags of fertilizer to cover the area of the triangle.

Step-by-step explanation:

To find the area of a triangle, we can use Heron's formula. Heron's formula states that the area of a triangle can be found by taking the square root of the semi-perimeter multiplied by the difference of the semi-perimeter and each side length.

The semi-perimeter of the triangle is (2.1+1.8+2.7)/2 = 2.7

The area of the triangle is sqrt(2.7*(2.7-2.1)(2.7-1.8)(2.7-2.7)) = sqrt(2.70.60.9*0) = 1.35

Each bag of fertilizer covers 0.2 square miles, so we need to divide the area of the triangle by the area covered by each bag to find how many bags are needed: 1.35 / 0.2 = 6.75

Rounding up to the nearest whole number, we would need 7 bags of fertilizer to cover the area of the triangle.

The points on this graph represent a relationship between x- and y-values. Which statement about the relationship is true?

Answers

The statement about the relationship of the data in the table is indicated in the option;

It can not be proportional because the straight line through the points does not go through the origin

What is a proportional relationship?

A proportional relationship is one in which one variable (the output variable) is a constant multiple of the input variable, such that a point on the graph of ordered pairs of variable is the point (0, 0), which is the origin.

The points on the graph are; (1, 3.5), (2, 4.5), (3, 5,5)

The slope of the graph is therefore; (4.5 - 3.5)/(2 - 1) = 1

The equation in point-slope form is therefore; y - 3.5 = x - 1

y = x - 1 + 3.5 = x + 2.5

y = x + 2.5

The equation is a linear relationship. The equation is in the form; y = m·x + c, with the slope m = 1 and a y-intercept, c = 2.5

The y-intercept is 2,5, therefore, the graph does not pass through the origin.

The relationship of the line passing through the points, is a linear relationship. The line passing through the points does not pass through the origin, therefore the relationship is not a proportional relationship

The correct option is therefore; It cannot be a proportional because the straight line through the points does not go through the origin.

ZA and B are vertical angles. If m/A= (2x +20)° and m/B = (3x + 1)°,
then find the value of x.

Answers

Answer:

The value of x is -19.

Step-by-step explanation:

Given that ZA and B are vertical angles and m/A = (2x +20)°, and m/B = (3x + 1)°, we know that ZA and B are congruent, meaning they have the same measure. We can set the two given equations equal to each other: m/A = (2x + 20)° = m/B = (3x + 1)°. Then, by isolating x on one side of the equation, we subtract 20 from both sides of the equation, then subtract 2x from both sides of the equation, which gives us x = -19, thus the value of x is -19.

Answer:

x = 19

Step-by-step explanation:

since vertical angles are equal we can set the value of angles A and B equal and solve for 'x'

2x + 20 = 3x + 1

20 = x + 1

When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this?

Fast food chains that use plastic or styrofoam containers in selling their products are contributing to the global plastic pollution crisis. Styrofoam and plastic containers, which are not biodegradable, take up to 1000 years to decompose.

Every year, an estimated 8 million metric tons of plastic end up in the ocean, and the majority of it is from single-use plastic products such as those used by fast food chains. This plastic pollution is having a devastating effect on the environment, with marine life ingesting and becoming entangled in the plastic. In addition, the production of styrofoam and plastic containers is highly energy intensive and contributes to the emission of greenhouse gases. This is a problematic situation that needs to be addressed urgently.

The energy intensity of production for styrofoam and plastic containers can be calculated using the formula:

Energy Intensity (EI) = Energy Used (EU) / Output (O)

For example, if it takes 50 kWh of energy to produce a unit of output, the energy intensity of production would be 50 kWh/unit. This highlights the environmental impact of styrofoam and plastic containers, and the urgent need to reduce their use in fast food chains.
