Write a multiplication equation with one variable and one fraction that has a solution 8

The maximum number of points on the convex hull of a set of 100 points inside a square is 4.

A Convex Hull is defined as  the smallest convex polygon which contains all the points in a set.

Since the points are inside a square, which means : the convex hull must be a subset of the square's boundary. The boundary of the square has 4 sides, so the maximum number of points on the convex hull is 4.

In Square , the number of points on the convex hull is a function of the distribution of the points and the shape of the region in which they are located.

Therefore , the maximum number of points on the convex hull of a set of 100 points inside a square is 4.

To show the work:

68 ÷ 0.4 = 170

Explanation:

You can think of dividing by a fraction as multiplying by its reciprocal. The reciprocal of 0.4 is 1/0.4.

So instead of dividing 68 by 0.4, you can multiply it by 1/0.4, which is the same as multiplying by 2.5.

68 * 2.5 = 170

the point of intersection of equation and the x value of that would be the solution. then You get the coordinate (2.3, 4.1). So x = 2.3, y = 4.1

Put both of those equations into slope intercept form (in order to be typed into the graphing calculator).

2x + 3y = 16.9

3y = -2x + 16.9

y = (-2/3)x + 16.9/3

5x = y + 7.4

5x - 7.4 = y

So in the graphing calculator,

Y1 = (-2/3)x + 16.9/3

Y2 = 5x - 7.4

Then find the point of intersection and the x value of that would be the solution.

You get the coordinate (2.3, 4.1). So x = 2.3, y = 4.1

345 free throws

Step-by-step explanation:

To find the total number of free throws Caroline attempted, we can set up the equation: (total free throws) x 0.20 = 69 (missed free throws)

Solving for the total free throws:

(total free throws) = 69 / 0.20

(total free throws) = 345

So Caroline attempted 345 free throws in the season.

Persons over the age of 40, African-Americans, people with hypertension or pre-hypertension, and people with diabetes are among these populations. Anyone in these groups should restrict their daily salt consumption to 1,500 mg.

Blood sodium levels should be between 135 and 145 mEq/L (3.10 mg/ml to 3.34 mg/ml). Higher sodium levels are often connected with hypertension. Hypernatremia is defined as a sodium level of 150 mEq/L (3.45 mg/ml) or higher, which is frequently caused by dehydration or ingesting too much salt. On some food labels, the salt amount is the sole information provided. To convert sodium to salt, increase the quantity by 2.5.

The patient should receive 50 gtt/min of heparin using a 60 gtt/ml set.

The unitary method is a useful tool in determining the amount of medication to be administered in a given time period.

The physician has ordered a medication called heparin, which is used to prevent blood clots.

The physician has ordered the patient to receive 1250 units of heparin per hour.

You have a solution of 50,000 units of heparin in 1000 ml.

To calculate the number of drops of heparin that the patient should receive per minute, we will use a method called the unitary method.

First, we need to determine the flow rate in ml/hr.

=> 50,000 units / 1000 ml = 50 ml/hr.

Now, we need to convert this to drops per minute.

=> 50 ml/hr x 60 gtt/ml = 3000 gtt/hr.

Finally, we divide the total number of drops per hour by 60 to get the number of drops per minute. So,

=> 3000 gtt/hr / 60 minutes = 50 gtt/min.

The dilation is am enlargement or a reduction then the scale factor be 2.

The ratio of one object's scale to that of a new object, which has its representation but is larger, is known as a scale factor (bigger or smaller).

To scale shapes in various dimensions, utilize the scale factor. Different geometrical shapes, both in two- and three-dimensions, are covered in geometry classes. The scale factor is a way to compare figures that appear to be similar but actually have distinct scales or measurements.

A scale factor is the amount by which a thing is multiplied to produce a separate object that has the same appearance but is a different size. It creates a precise copy that is just bigger or smaller than the original. Scale Factor multiplies the image or object in the same way as a copy machine would enlarge or reduce it.

Taking two points and dividing them would yield the factor.

For instance, if the point was between x = 2 and x = 4, their division would be 4/2 = 2, as shown on the right side.

Now, if we split the points x = -1 and x = -2 on the left side, we get -2/-1 = 2.

The time take for the object to cool down is 5 minutes.

The temperature of a substance is a measure of its thermal energy and it is important to know how it changes over time.

Heat transfer occurs from hot to cold, meaning that the coffee will transfer heat to the room until both reach thermal equilibrium. The temperature difference between the coffee and the room is

=> 80°C - 25°C = 55°C.

We will use this value to calculate the rate of heat transfer. We know that the final temperature of the coffee will be 45°C, so the temperature difference will become

=> 45°C - 25°C = 20°C.

The time it takes to cool from 80°C to 45°C will depend on the heat transfer rate, which is affected by factors such as the mass of the coffee, the material of the container, and the surrounding environment.

Let us consider that the average heat rate is 60 seconds that is one minute.

Step-by-step explanation:

It is true that if v in r3 and v·v = 0, then v is the zero vector.

If v is a vector in R3 (three-dimensional real space) and v·v = 0, then v is the zero vector.

The dot product of a vector with itself, v·v, is equal to the square of the magnitude of the vector, ||v||^2. If v·v = 0, it follows that ||v||^2 = 0, which means that the magnitude of v is 0. In other words, v has a length of 0.

The only vector in R3 with a length of 0 is the zero vector, which is represented by the vector (0, 0, 0). Thus, if v·v = 0, v must be the zero vector.

The unit digit of the product of 91, 92, 93, ... 99 is 0.

The digit that goes in the place of one in a number is known as the unit digit. i.e. It is the number's rightmost digit. As an illustration, the unit digit for 243 is 3, whereas the unit digit for 39 is 9.

It is easy to identify the unit place digit of the smaller number but when it comes to the numbers raised to the larger power it becomes difficult to identify the same by simple observation. It is when the concept of cyclicity comes into the picture.

The cyclicity concept is based on the fact that every digit in the number has its own repetitive pattern when raised to any specific power. This particular concept makes it easy for the students to find the unit place digit of the larger numbers and that too at much less time. So, let's learn about the cyclicity concept.

For example: - 2² = 4. Here, the unit digit is 4

2³ = 8. Here, the unit digit is 8.

Given:

We want to find unit digit of the product of the numbers.

Here two digit is 92 and 95.

If we multiply 92 and 95, we will get zero as unit digit and if we multiply any digit by zero, unit digit always be zero.

So, the product of 92× 95 has zero in unit place.

So, in product of all numbers 91 × 92 × 93......×98 × 99 the unit will be zero. Because when we multiply any number by zero it become zero.
