Does standard form have to be between 1 and 10?
No, standard form does not have to be between 1 and 10. Standard form refers to a way of writing a number in which the number is expressed as a decimal between 1 and 10, multiplied by a power of 10.
THE STANDARD FORMStandard form, also known as scientific notation, is a way of writing a number that is a product of a decimal between 1 and 10, and a power of 10. The decimal part is called the coefficient, and the power of 10 is called the exponent.
For example, 12,000 can be written in standard form as 1.2 x 10⁴. Here, the coefficient is 1.2 (a decimal between 1 and 10) and the exponent is 4, indicating that the number is being multiplied by 10 raised to the power of 4 (10,000).
It is important to note that standard form is not limited to positive numbers and decimals between 1 and 10. A negative number or decimal less than 1 can also be written in standard form, but it would be multiplied by a power of 10 that is less than 1.

Kaj signed up for a streaming music service where there's a fixed cost for monthly
membership and a cost per song downloaded. Her total cost per month is given by
the equation c = 1.5x + 6.99, where X represents the number of songs she
downloads and c represents the total cost, in dollars and cents. What could the
number 1.5 represent in the equation?
In the equation for total cost c = 1.5x + 6.99, 1.5 represents the cost of per song downloaded.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
The equation for total cost per month is c = 1.5x + 6.99.
Where x represents the number of songs Kaj downloads and c represents the total cost, in dollars and cents.
So, c and x are variable components of the equation.
There are only two fixed components in the equation 1.5 and 6.99.
Since number of songs downloaded x is multiplied by 1.5, so 1.5 is the cost of per song downloaded.
Hence, 6.99 becomes the fixed monthly membership cost of the music service.
Therefore, 1.5 is cost of per song downloaded.

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.

a farmer planted 320 acres of one variety of wheat and one160 acres of a second variety. He also planted 40 acres of milo, and he has 440 acres that will lie fallow (not be planted) this year. What percent of his land di he plant in wheat? Round to the nearest percent
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,
and he has 440 acres that will lie fallow
Total land farmer has = 320 + 160 + 40 + 440 = 960 acres
Land planted with wheat = 320 + 160 = 480 acres
Percentage of land with wheat
= (land planted with wheat/ total land)× 100
= 480/960 × 100
= 0.5 × 100
= 50%

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.

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
8x = 96
⇒ x = 12
Therefore, the values are y = 16/3 and x = 12.

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)
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

Im having issues with this question does anyone know this question STEP BY STEP
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
Thus, the area of one circle is 48 in² if the butcher paper is 24 inches long.
