A concrete tank has an external diameter of 10 m and an internal height of 3 m. If the walls and bottom of the tank are 30 cm thick, how many cubic metres of concrete are required to make the tank?

If an area of the circle is 200.96 cm^2 , then the circumference of the same circle is approximately around 28.28 cm^2.

The formula for the area of a circle is given by:

A = πr^2,

where A is the area and r is the radius of the circle.

To find the circumference of a circle, we can use the formula:

C = 2πr,

where C is the circumference and r is the radius.

To solve for the circumference, we first need to find the radius of the circle. We can use the formula for the area to find the radius:

A = πr^2

200 = πr^2

r^2 = 200 / π

r = √(200 / π)

Next, we can substitute the value of r into the formula for the circumference to find the circumference:

C = 2πr

C = 2π * √200 / π)

C = 2 * √(200)

Approximating √(200) to 14.14, we get:

C ≈ 2 * 14.14 = 28.28

So the approximate circumference of a circle with an area of 200 square cm is 28.28 square cm.

Answer: 11

Step-by-step explanation:

We need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), to simplify the expression:

1: First, we solve the exponent 3², which is 3 multiplied by itself, or 3 x 3 = 9.

2: So, the expression now becomes: (3 x 4) ÷ 6 + 9

3: Next, we solve the multiplication, which is 3 x 4 = 12.

4: So, the expression becomes: 12 ÷ 6 + 9

5: Then, we solve the division, which is 12 ÷ 6 = 2.

6: So, the expression becomes: 2 + 9

7: Finally, we solve the addition, which is 2 + 9 = 11.

The area of the shape for the quilt block is eighty three three - fifth (83 3/5) inches square.

It should be noted that to find the area of this six-sided figure, we can break it down into two right triangles and a rectangle.

First, let's find the area of the right triangle with the 4-inch side. This triangle has a base of 4 inches and a height of 5 inches, so the area is (1/2) * 4 * 5 = 10 square inches.

Next, let's find the area of the right triangle with the 5-inch side. This triangle has a base of 5 inches and a height of 4 inches, so the area is (1/2) * 5 * 4 = 10 square inches.

Finally, let's find the area of the rectangle. This rectangle has a base of 10 and three-fifths inches and a height of 6 inches, so the area is (10 + 3/5) * 6 = 63 3/5 square inches.

Based on the low correlation value of 0.05, Bob concludes that the number of bedrooms in a home is not a strong predictor of its selling price.

The statistical method called correlation to measure the strength of the relationship between these two variables.

A correlation value of 0.05 indicates that there is a weak relationship between the number of bedrooms in a home and its selling price. In statistical terms, this means that the number of bedrooms in a home only explains 5% of the variation in the selling price.

A correlation value can range from -1 to 1.

A value of -1 indicates a perfect negative correlation, meaning that as the number of bedrooms in a home increases, the selling price decreases.

A value of 1 indicates a perfect positive correlation, meaning that as the number of bedrooms in a home increases, the selling price also increases.

A value of 0 indicates no correlation, meaning that there is no relationship between the number of bedrooms in a home and its selling price.

Other factors, such as location, square footage, and the overall condition of the home, likely play a larger role in determining the selling price.

If sine0=1/3 then the values of

cos0 = 2/3

tan0 = 1/2

Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.

There are 6 commonly used functions in trigonometry with their name and abbreviations-

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec)

Given that sin 0 = 1/3, we can use the Pythagorean theorem to find the value of cos 0:

cos² 0 + sin² 0 = 1

cos² 0 = 1 - (sin 0)²

cos 0 = √(1 - (sin 0)²)

cos 0 = √(1 - (1/3)²)

cos 0 = √(1 - 1/9)

cos 0 = √(8/9)

cos 0 = √2/3

Next, we can use the relationship between sine and tangent to find the value of tan 0:

tan 0 = sin 0 / cos 0

tan 0 = 1/3 / 2/3

tan 0 = 1/2

So, the values of cos 0 and tan 0 are 2/3 and 1/2, respectively.

Answer:

During the Holocaust, Jews who were living in Nazi-occupied countries were more vulnerable than German Jews for several reasons. First, German Jews had some level of protection under German law until 1935, when the Nuremberg Laws stripped them of their citizenship and legal rights. In contrast, Jews in occupied countries had no legal protection or rights.

Second, German Jews had more resources and networks to help them escape persecution or go into hiding, such as family members or friends who were not Jewish or non-Jewish organizations that were sympathetic to their plight. Jews in occupied countries, especially in Eastern Europe, often had less access to resources and networks because they were living in ghettos or had been transported to concentration or extermination camps.

Third, German Jews were often better-educated and assimilated into German society, which sometimes gave them advantages in finding employment or housing. Jews in occupied countries, especially in Eastern Europe, often lived in poverty and were more likely to be living in rural areas or small towns, which made them more vulnerable to persecution and deportation.

This suggests that the society's "universe of obligation" during the Holocaust was limited to certain groups of people, namely German Jews who were seen as having more value or worth than Jews in other countries. This limited universe of obligation meant that Jews in occupied countries were not considered as valuable or worthy of protection, and therefore were more vulnerable to persecution and violence. The Holocaust serves as a tragic example of how societies can create a narrow universe of obligation that excludes entire groups of people and leads to horrific consequences.

To convert 3/5 to a decimal, we divide the numerator by the denominator  and we get 0.6. 3/5 as a decimal is 0.6.

To convert 3/5 to a decimal, we divide the numerator (3) by the denominator (5):

3 ÷ 5 = 0.6

Therefore, 3/5 as a decimal is 0.6.

Converting a fraction to a decimal involves dividing the numerator by the denominator. To convert 3/5 to a decimal, we can use long division or a calculator to perform the division. In this case, 3 divided by 5 equals 0.6. Alternatively, we can also recognize that the fraction 3/5 can be written as a decimal by dividing the numerator by the denominator. Since 3 is the same as 3.0, we can add a decimal point after 3 and divide by 5 to get 0.6. The decimal form of a fraction can be useful for making comparisons or performing calculations with other decimal numbers.

1. Translation – (x+3, y-3) :

To move the figure 3 units to the right in the x-direction and 3 units down in the y-direction.

2. Dilation – Reduce the figure by ½ is:

When reducing a figure by ½, every dimension of the figure is divided by 2.

3. Reflection- Reflect over the line y = x

Reflecting over the line y = x means that every point in the figure is reflected over the line that goes diagonally from the lower left to the upper right.

4. Rotation – Rotation of 180 degrees around the origin.

When rotating a figure 180 degrees around the origin, every point in the figure is moved to a new location that is 180 degrees around the origin from its original location.

Translated to plain English, this means to move the figure 3 units to the right in the x-direction and 3 units down in the y-direction. When we apply the translation (x+3,y-3) to a figure, it means that we move the entire figure 3 units to the right in the x-direction, and 3 units down in the y-direction. So, the translation (x+3,y-3) simply shifts the figure to a new location that is 3 units to the right and 3 units down from its original location.

Dilation is a transformation that changes the size of a figure. When reducing a figure by ½, every dimension of the figure is divided by 2. In other words, every point in the figure is moved to a point that is half the distance from the center of dilation.

Reflecting a figure over a line means to create a mirror image of the figure on the other side of the line. Reflecting over the line y = x means that every point in the figure is reflected over the line that goes diagonally from the lower left to the upper right.

Rotating a figure means to turn it around a fixed point. When rotating a figure 180 degrees around the origin, every point in the figure is moved to a new location that is 180 degrees around the origin from its original location. This means that every point is flipped over to the opposite side of the origin.
