The greyhound's speed is 39.18 miles per hour greater than the tortoise's speed.
The giant tortoise can move at speeds of up to 0.17 mile per hour and the top speed for a greyhound is 39.35 miles per hour.
So, we can find the difference in speed between these two animals as follows:
Difference in speed between the greyhound and tortoise = Speed of the greyhound - Speed of the tortoise
Difference in speed = 39.35 - 0.17
Difference in speed = 39.18 miles per hour
Therefore, the greyhound's speed is 39.18 miles per hour greater than the tortoise's speed.

What is the additive inverse of _2 9?
The additive inverse of 2 9 is -2 9. This means that if you add -2 9 to 2 9, the result will be zero. This is because any number plus its opposite will equal zero.
2 9 + (-2 9) = 0
20 + (-20) = 0
The additive inverse of a number is the opposite of that number. This means that the inverse of 2 9 would be -2 9. When you add a number and its inverse together, the result is always zero. This is because any number plus its opposite will equal zero. For example, if we take 2 9 and add it to its inverse -2 9, the result will be 0. This is because 20 + (-20) = 0. The same concept can be applied to other numbers as well. For instance, if we take 3 4 and add it to its inverse -3 4, the result will be 0 because 34 + (-34) = 0. This shows that the additive inverse of a number is the opposite of that number, and when a number and its inverse are added together, the result is always zero.

Can 7 cm 8 cm 11 cm form a triangle?
No, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side for a triangle to be formed.
In order to determine whether 7 cm, 8 cm, and 11 cm can form a triangle, we must first consider the Triangle Inequality Theorem. This theorem states that the sum of any two sides of a triangle must be greater than the length of the third side in order for a triangle to be formed. Therefore, in order for 7 cm, 8 cm, and 11 cm to form a triangle, the sum of any two sides must be greater than 11 cm. Since
7 cm + 8 cm = 15 cm,
which is less than 11 cm, 7 cm, 8 cm, and 11 cm cannot form a triangle.

A table can be read from top to bottom or left to right. When reading a table across a row, you should read the data from left to right.
what is sequence ?In mathematics, a sequence is a list of items that is in a particular order (or events). It has members and is comparable to a set (also called elements, or terms). The amount of ordered elements determines how long the sequence is (potentially infinite). The four basic types of sequences that you should be knowledgeable about are arithmetic sequences, geometric sequences, quadratic sequences, and special sequences. A number sequence is a collection of integers connected by a pattern. If you understand the rule, you can determine the subsequent numbers in the sequence. In this case, there is a 6 difference between each number. As a result, the rule for this sequence is to add 6 each time.

Is A ={ x x 2 )= 4 and 3x 9 an empty set justify your answer?
The value of 'x' is not same in both cases, so this is a empty set.
How to calculate A={x x 2}=4 and 3*9 an empty set?step1
Because here square of element of set should be 4 then element should be 2 or -2 but when 2 or -2 multiplied by 3 gives 6 or - 6 which is not equal to 9. So, no element exists which can satisfy both conditions.
A={x x 2}=4 and 3x=9 is not empty set because there is no element we can say that is an empty set but there is an element, so it is not an empty set.
step2
X^2=4
Therefore only 2's square is 4
In first equation X=2

3x=9
Therefore here X=3

y = 3.2 when x = 30. Find the value of x when
y = 8.
The equation of variation is xy = 96. The value of y when x = 18 is 16/3 and the value of x when y = 8 is 12.
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
Given:
y inversely varies as x.
That means, y ∝ 1/x.
So, y = kx, where k constant of variation.
Then, x × y = k
When y = 16, x = 6.
k = 6 × 16 = 96
So, the equation of variation is xy = 96.
When x = 18,
18y = 96
⇒ y = 96/18
⇒ y = 16/3
When y = 3.2,
3.2(30) = 96
When y = 8

Percent of land planted with wheat is 50% of total land.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given,
a farmer planted
320 acres of one variety of wheat
160 acres of a second variety of wheat.
He also planted 40 acres of milo,

So the total area of the South China Sea and the Arctic Ocean is 2.10286 x 107 km2
To find the total area of the South China Sea and the Arctic Ocean, you would add their individual areas together.
The formula for finding the total area is:
Total Area = Area of South China Sea + Area of Arctic Ocean
By applying this formula we get:
Total Area = 6.963 × 106 km2 + 1.4056 × 107 km2
Total Area = 2.10286 x 107 km2
So the total area of the South China Sea and the Arctic Ocean is 2.10286 x 107 km2. The final answer is correct and has correct number of significant digits as per the given figures.

The area of one circle is 48 in² if the butcher paper is 24 inches long.
What is area?
The area of a two-dimensional figure is the total area it takes up. It is the quantity, in other words, that counts the number of unit squares that cover the surface of a closed figure.
Square units—commonly expressed as square inches, square feet, etc.—are the accepted unit of area.
Given that:
3 congruent circles are perfectly fitted in the rectangular banner of length 24 inches,
⇒ diameter of each circle = length of rectangular banner/3
⇒ d = 24/3
⇒ d = 8
⇒ r = 8/2
⇒ r = 4
Area of circle, A = π r²
A = 3× 4 × 4 (used pi as 3 as instructed in the question)
A = 48 in²

Best Buy is selling a 62" TV for $1,250. The TV is on sale for 15% off and there is a 6% sales tax. What is the final cost of the TV? Please help me I don't know how to do it
Answer:
final cost of 42" TV after deducting 15% discount and adding 6.5% sales tax will be $1163.56
Step-by-step explanation:
final cost of 42" TV after deducting 15% discount and adding 6.5% sales tax will be $1163.56
The final cost of the TV would be $1,063.50.
To calculate this:
First, calculate the discount by multiplying the original price of the TV ($1,250) by 15% (0.15). This equals $187.50.
Subtract the discount from the original price of the TV ($1,250 - $187.50 = $1,062.50)
Next, calculate the sales tax by multiplying the price after the discount ($1,062.50) by 6% (0.06). This equals $63.75
Finally, add the sales tax to the price after the discount ($1,062.50 + $63.75 = $1,063.50)
