The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is,

⇒ x²+ (y - 6)² = 36

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Now, We know that;

The standard form for finding the equation of a circle is expressed as;

⇒(x - a)² + (y - b)² = r²

where; (a, b) is the center of the circle and r is the radius of the circle.

Here, we have;

⇒ Diameter = 12 units

⇒ Radius = 12/2 = 6 units

Since, The center lies on the y-axis,

Hence, the center will be at (0, 6).

Substituting into the formula, we will have;

⇒ (x - 0) + (y - 6)² = 6²

⇒ x² + (y - 6)² = 36

It is not possible to construct a triangle whose sides are 3 cm 4 cm and 7 cm because the sum of two sides(3 cm and 4 cm) are equal to the third sides(7 cm). The equal sides can not form a triangle.

In the given question, we have to check that it is possible to construct a triangle whose sides are 3 cm 4 cm and 7 cm.

To check whether the given sides can make a triangle or not, we have to check that the sum of two sides always grater than the third side.

To check this we firstly add the 3 and 4

3 + 4 = 7

7 = 7

Now we add 3 and 7

3 + 7 > 4

10 > 4

Now we add 4 and 7

7 + 4 > 3

11 > 3

Probability of selection is one that defines the probability that a population unit is included in a sample generated by probability sampling.

For any population, the probability of any element within that population to be selected into a sample is calculated as the sample size divided by the population size.

In this case, we are told that the dog shelter has Labradors, Terriers, and Golden Retrievers available for adoption. There are three types of dogs.

We are given;

The volume of a cylindrical = πr²h where r is

the radius of the base of the cylinder and h is the height.

The hemisphere and the cylinder will have the same radius r =0.25cm

Since the total length of the toy is 2 cm, the length of the conical part

Therefore , the solution of the given problem of inequality comes out to be (x,y) = (1,4).

An inequality in mathematics is a relationship between two concepts or variables that isn't comparable. Therefore, inequality follows imbalance. When two integers are not equal, there is an inequality in mathematics. Egality and inequality are different. When two values aren't genuinely equal, the not equal basic is usually used to indicate this (). The values, whether tiny or huge, are contrasted using a variety of inequalities. By alternating the two characteristics until the constants integers become the only thing left, it is possible to solve many straightforward inequalities. However, a few things promote inequality: Negative values are halved or added to either side.

Here,

Given :

y≤ 3x+1

x-y>1

To find the value of x and y :

y≤ 3x+1

put the value of y

=> x - 3x -1 > 1

=> -2x -1>1

=>-2x > 2

=> -x>1

=>x >-1

d = 0.4 p, where the sales price of the bookshelf is $51, is the function that depicts the percentage off of a regular price.

When an item's price is lowered, it is said to be on sale. Multiplying the cost of an item by the % discount will give you the discount's value.

Discount = Original Price × Percentage Discount

$85 × 40%

$85 × 0.4 = $34.

Original cost less any discounts equals sales price.

$85 - $34 = $51.

The discount is the amount that separates an item's selling price from its marked (or list) price. Discount is therefore calculated as follows: Discount=List price – Selling price. Take advantage of deals like the buy one, get one free promotion or 15% off shirts, for instance. On an item with a price per hundred displayed, you have a percentage discount.
