Final answer:
A fraction is a multiple of 1/9 if it can be written as a whole number multiplied by 1/9. For example, 2/9 is a multiple of 1/9 because it is obtained by multiplying 1/9 by 2.
Explanation:
To find which fraction is a multiple of 1/9, one can multiply 1/9 by any whole number. For instance, if we multiply 1/9 by the number 2, we obtain 2/9. This resulting fraction is indeed a multiple of 1/9 since we have simply doubled the numerator while keeping the denominator the same. When we multiply both the numerator and the denominator by the same factor, we are maintaining the proportion, hence a multiple of 1/9.
So the question at hand is about identifying a fraction that, when simplified, would be a whole number times 1/9. Such fractions can be formed by multiplying the numerator (1) of 1/9 by any non-zero integer and keeping the denominator (9) constant. For example, 3/9 is a multiple of 1/9 as 3 is a whole number and 3/9 can be simplified to 1/3, which is 3 times 1/9.

456 000 has been rounded to the nearest thousand. What was the smallest possible number this could have been?
Answer:
The smallest possible number this could have been = 455500
Step-by-step explanation:
456000 has been rounded to the nearest thousand.
If the value is more than 456500 the value rounded to the nearest thousand is 457000.
If the value is less than 455500 the value rounded to the nearest thousand is 455000.
In between 455500 and 456500 the value rounded to the nearest thousand is 456000.
So, The smallest possible number this could have been = 455500

If the circumference of a circle measures 3/2 π cm, what is the area of the circle in terms of π?
The area of the circle with a circumference of 3/2 π cm is 9/16 π cm².
Explanation:The question is asking about finding the area of a circle when the circumference is given. The formula to find the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle. Given that the circumference is 3/2 π cm, we can use this information to find the radius.
From the circumference equation, r = C/2π = (3/2π)/ 2π = 3/4 cm. Having the radius, we can then use the formula for the area of a circle, which is A = πr². As a result, the area of the given circle is π(3/4)² cm² which simplifies to 9/16 π cm².

Which of these might be used to determine common ancestry of two different species of plants? A. similar ecological niches B. fossil evidence C. the size of the population D. similar habitats
its science they wouldnt let me pick it so i had to put math
Final answer:
Fossil evidence, morphological, and genetic similarities are key factors in determining common ancestry of species, with fossil evidence being particularly definitive for extinct life forms.
Explanation:
To determine common ancestry of two different species of plants, scientists would most likely consider fossil evidence as a primary source. Fossils provide concrete evidence about extinct life forms and can give more accurate dates of divergence. Morphological (form and function) and genetic evidence are other crucial factors in establishing evolutionary connections among organisms. Similar physical features and genomes usually indicate a closer relationship, with homologous structures stemming from common evolutionary paths. Therefore, similar ecological niches or habitats may suggest a relationship, but they are not as definitive as morphological and genetic similarities and fossil evidence in determining a shared ancestry.

The cost of 7 drinks is $16.38. What is the cost of each drink?
$1.54
$1.88
$2.34
$2.73
The cost of each drink if 7 drinks cost $16.38 is $2.34.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that the cost of 7 drinks is $16.38. Therefore, the cost of each of the drink will be:
Cost of each drink = Cost of all the drinks / Number of drinks
= $16.38 / 7
= $2.34
Hence, the cost of each drink is $2.34.

While attending a college football game, you think you can guess the attendance within 10% of the actual value. If the announced attendance is 65,000, within what number of people would your guess have to be in order for you to support your claim?
Answer:
13,000 People
Step-by-step explanation:
65,000 (0.1) = 6500
6500 (2) = 13,000
You multiply by 2 to get 10% above or below the announced attendance.
Answer:
6,500
Step-by-step explanation:
If you think you can guess the attendance within 10% of the actual value, then your guess would have to be within 6,500 of the actual attendance of 65,000 in order for you to support your claim. This is because 10% of 65,000 is 6,500. So if your guess is within 6,500 of the actual attendance, then you can support your claim.

If the diagonals of a quadrilateral are perpendicular, is the quadrilateral always a rhombus?
No, a quadrilateral with perpendicular diagonals is not always a rhombus. While a rhombus has perpendicular diagonals, other quadrilaterals like a square share this property.
While a rhombus does have perpendicular diagonals, other quadrilaterals, such as a square, also possess this property.
Therefore, if the diagonals of a quadrilateral are perpendicular, it does not exclusively imply that the quadrilateral is a rhombus.
Additional conditions, such as equal side lengths, are necessary to establish the quadrilateral as a rhombus.
Thus, perpendicular diagonals are a characteristic of both rhombuses and squares, but not solely indicative of a rhombus.

What is the area of the table?
Use 3.14 for π .
Enter your answer, as a decimal, in the box.
(?) ft²
Answer: The area of the circular wooden table = 50.24 ft²
Step-by-step explanation:
Given: The radius of the circular table = 4 feet
We know that area of a circle is given by :-
[tex]\text{Area}=\pi r^2[/tex]
Therefore, the area of circular wooden table is given by :-
[tex]\text{Area}=3.14(4)^2\\\Rightarrow\ 3.14\times16\\\Rightarrow\text{Area=}50.24\ ft^2[/tex]
The area of the circular wooden table = 50.24 ft²
Answer: 50.24
Step-by-step explanation:
We know: The radius = 4 feet and that the area of a circle = πr^2
Next: (π) 3.14 (4)^2
which we can simplify to be 3.14 * 16
= 50.24

A pyramid has all sides that are equilateral triangles. Each triangle has side lengths of 9 centimeters. If the surface area of the pyramid is 140 4 square centimeters, what is the slant height of the pyramid
A pyramid has all sides that are equilateral triangles. Each triangle has side lengths of [tex]9[/tex] centimeters. If the surface area of the pyramid is [tex]140.4[/tex]square centimeters, the slant height of the pyramid is [tex]Slant height= 2*(140.4-81\sqrt{3} )/27[/tex]
To find the slant height of the pyramid, we first need to determine the lateral area of one of the triangular faces of the pyramid.
Since all sides of the equilateral triangle have a length of [tex]9[/tex] centimeters, we can use the formula for the area of an equilateral triangle, which is:
[tex]A=\sqrt{3} /4*side length^{2}[/tex]
Substituting the given side length [tex]9[/tex] centimeters into the formula:
[tex]A=\sqrt{3} /4*9^{2} \\A=\sqrt{3} /4*81\\ A=81\sqrt{3}/4[/tex]
Now, since there are four equilateral triangular faces on the pyramid, the total lateral area of the pyramid is [tex]4*81\sqrt{3}/4=81\sqrt{3}[/tex] square centimeters.
Given that the total surface area of the pyramid is [tex]140.4[/tex] square centimeters, we subtract the area of the base (which is also an equilateral triangle) from the total surface area to find the lateral surface area:
[tex]Lateral surface area=Total surface area-Area of base\\Lateral surface area=140.4-81\sqrt{3}[/tex]
Now, the lateral surface area of a pyramid can be calculated using the formula:
[tex]Lateral surface area=12*perimeter of base*slant[/tex]
For an equilateral triangle, the perimeter is [tex]3*side length=3*9= 27[/tex]centimeters.
So, we have:
[tex]140.4-81\sqrt{3} =1/2*27*slant height\\140.4-81\sqrt{3} =27/2*slant height\\Slant height=2*(140.4-81\sqrt{3} )/27[/tex]
Calculating this expression gives us the value of the slant height of the pyramid.
