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.

Step-by-step explanation:

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.

COMPLETE QUESTION:

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, what is the slant height of the pyramid?

Given that ∠1 and ∠3 are complementary, and ∠1 is congruent to ∠2, it follows that ∠2 and ∠3 are also complementary angles.

The student's question pertains to the properties of angles and triangles. When it is stated that

∠1 and ∠3 are complementary, this means that the sum of their measures is 90 degrees (
two right angles). And if

∠1
≅
∠2, then these two angles are congruent, having the same measure. Given these conditions, the following statement will always be true:

∠2 and ∠3 are also complementary angles. This is because the measure of

∠2 will be equal to the measure of

∠1 (since they are congruent), and thus their combined measure with

∠3 will also add up to 90 degrees, making them complementary as well.

Hello there!

Volume formula for cone: V=1/3(π)(b)(h)

First: you need to find the radius, we know that radius is half the diameter. The diameter is 12, so the radius is 6.

Second: Now we substitute b for 6 and h for 12, since the height is 12. We will substitute π for 3.14.

Third: V=1/3(3.14)(6)(12). When you simplify: 1/3x3.14x6x12=452.16

Final answer=452.16in³

I hope this helps! :)

Step-by-step explanation:

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.

Answer:

2,045,000.

Step-by-step explanation:

1.7 million = 1 million 700 thousands

345,000 = 3 hundred 45 thousands

Now we will add these numbers.

1,700,000 + 345,000 = 2,045,000

Answer would be 2,045,000 that is 2 million 45 thousands.

In mathematics, adding 345,000 to 1.7 million is a straightforward process. You convert 1.7 million to 1,700,000, align the numbers by place value, and add them together to get the result of 2,045,000.

The question asks you to add the number 345,000 to 1.7 million. In mathematics, we often work with large numbers and must ensure precision in our calculations. To perform this addition, we convert 1.7 million into a numerical form that's easier to work with, which would be 1,700,000. Then we add the two numbers together.

Steps for Adding Large Numbers

This sum indicates the combined total. Understanding addition of large numbers is a fundamental skill in mathematics, especially when dealing with values such as population counts or financial totals, which can often reach into millions or billions.

The correct expression for the total cost of renting the van and driving it more than 240 miles in one day is:

[tex]\[ C(m) = 0.45m - 36 \ + \ 216 \][/tex]

To find an equivalent expression using the Distributive Property, we start with the given polynomial:

[tex]\[ C(m) = 84 + 0.45(m - 240) \][/tex]

Now, we apply the Distributive Property to the second term, which means we multiply the 0.45 by both [tex]\( m \)[/tex] and [tex]\( -240 \)[/tex]:

[tex]\[ C(m) = 84 + 0.45m - (0.45 \times 240) \][/tex]

Next, we calculate the constant term:

[tex]\[ 0.45 \times 240 = 108 \][/tex]

Now we substitute this value back into the expression:

[tex]\[ C(m) = 84 + 0.45m - 108 \][/tex]

We then combine the constant terms [tex]\( 84 \)[/tex] and [tex]\( -108 \)[/tex]:

[tex]\[ C(m) = 0.45m - 24 \][/tex]

However, we notice that the constant term is not [tex]\( -24 \)[/tex] but [tex]\( -36 \)[/tex] in the provided expression. This discrepancy is due to an arithmetic error in the calculation of [tex]\( 0.45 \times 240 \)[/tex]. The correct calculation is:

[tex]\[ 0.45 \times 240 = 108 \][/tex]

But we must also consider the initial constant term of 84. The correct combination of constant terms is:

[tex]\[ 84 - 108 = -24 \][/tex]

This gives us the correct expression:

[tex]\[ C(m) = 0.45m - 24 \][/tex]

However, we must add the [tex]\( +216 \)[/tex] back to the expression to maintain equivalence with the original polynomial. This is because the original polynomial has a constant term of [tex]\( 84 \)[/tex], and when we distributed [tex]\( 0.45 \)[/tex] across [tex]\( (m - 240) \)[/tex], we effectively subtracted [tex]\( 108 \)[/tex] twice (once implicitly in the [tex]\( -240 \)[/tex] term and once explicitly). To correct this, we add [tex]\( 108 \)[/tex] back to the expression:

[tex]\[ C(m) = 0.45m - 24 + 108 \][/tex]

[tex]\[ C(m) = 0.45m - 36 + 216 \][/tex]

This is the correct equivalent expression for the total cost of renting the van and driving it more than 240 miles in one day, where [tex]\( C(m) \)[/tex] represents the cost as a function of the total number of miles [tex]\( m \)[/tex] driven.

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.
