Answer:

42 : 28

Step-by-step explanation:

Sum the parts of the ratio , 3 + 2 = 5

Divide 70 by 5 to find the value of one part of the ratio

70 ÷ 5 = 14 ← value of 1 part of ratio, thus

3 parts = 3 × 14 = 42

2 parts = 2 × 14 = 28

70 divided in the ratio 3 : 2 is 42 : 28

Answer:

For the first cone: r = 7 cm, h = 21 cm

For the second cone: r = 8 cm, h = 24 cm

Step-by-step explanation:

The volume of the first cone is [tex]343\pi cm^3[/tex]

The volume of the second cone is [tex]512\pi cm^3[/tex]

We are told that the height of each cone is 3 times its radius, hence:

h = 3r

The volume of a cone is given as:

[tex]V = \frac{1}{3} \pi r^2h[/tex]

Substituting h = 3r:

[tex]V = \frac{1}{3} \pi r^2(3r)\\\\\\V = \frac{1}{3} \pi (3r^3)\\\\\\V = \pi r^3[/tex]

For the first cone, V = [tex]343\pi cm^3[/tex], radius, r, will be:

[tex]343\pi = \pi r^3\\\\\\=> r^3 = 343\\\\\\r = \sqrt[3]{343} \\\\\\r = 7 cm[/tex]

∴ Its height will be:

h = 3r = 3 * 7 = 21 cm

For the second cone, V = [tex]512\pi cm^3[/tex], radius, r, will be:

[tex]512\pi = \pi r^3\\\\\\=> r^3 = 512\\\\\\r = \sqrt[3]{512} \\\\\\r = 8 cm[/tex]

∴ Its height will be:

h = 3r = 3 * 8 = 24 cm

The radius and height of the first cone are 7 cm and 21 cm respectively while the radius and height of the second cone are 8 cm and 24 cm respectively.

Answer:

y = - [tex]\frac{3}{2}[/tex] x

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = - 4, y = 6, thus

6 = - 4k ( divide both sides by - 4)

[tex]\frac{6}{-4}[/tex] = k, or k = - [tex]\frac{3}{2}[/tex]

y = - [tex]\frac{3}{2}[/tex] x ← equation of variation

Step-by-step explanation:

The combination of Wendell and Maggie’s ages is 33. Let Maggie's age is x. It is mentioned that Wendell’s age is 3 less than 3 times the age of Maggie. It means, Wendell’s age is (3x-3).

ATQ,

[tex]x+(3x-3)=33\\\\4x-3=33\\\\4x=36\\\\x=9[/tex]

The age of Maggie is x. So, Wendell's age is :

[tex]y=(3x-3)\\\\y=(3(9)-3)\\\\y=24[/tex]

So, Wendell age is 24 years.

The most vital factor for classifying two species into the same group is if they evolved from a shared ancestor, reflecting their place in the same clade and genetic similarities.

The most important factor for classifying two species into the same group is their evolutionary history, specifically whether they evolved from a shared ancestor. When scientists classify species, they adhere to the fundamental principle that all members of a group, or "clade," must have a recent common ancestor that is not shared with species from other groups. This is based on the idea that species within the same group will share more genetic similarities and phylogenetic traits than with those from different groups due to their more recent common ancestry.

Option A might seem plausible, as species in a group often share similar traits, but shared traits alone are not enough for classification without evolutionary context. Option C is incorrect because common names do not reflect scientific classification. Option D is also incorrect as geographic location is not a determinant for taxonomic classification. Thus, the correct answer to the original question is B, "The species have different common ancestors," as having a recent common ancestor is the most critical criterion for grouping species together.

Answer: I'm probably wrong, but I think it's 2

Step-by-step explanation:  Estimate.

Given:

Given that AGN is a triangle with circle inscribed in it.

The circle touch the triangle at the point R, T and E.

The length of AR is 35 units.

The length of RG is 21 units.

The length of NE is 19 units.

We need to determine the perimeter of the triangle AGN.

Length of GE:

Since, we know the property that, "if two segments from a exterior point are tangent to the circle, then they are congruent".

Since, RG and EG from an exterior point G are tangents to the circle, then RG and EG are congruent.

Thus, we have;

[tex]RG=EG[/tex]

 [tex]21=EG[/tex]

Thus, the length of GE is 21 units.

Length of TN:

Since, we know the property that, "if two segments from a exterior point are tangent to the circle, then they are congruent".

Since, TN and NE from an exterior point N are tangents to the circle, then TN and NE are congruent.

Thus, we have;

[tex]TN=NE[/tex]

[tex]TN=19[/tex]

Thus, the length of TN is 19 units.

Length of AT:

Since, we know the property that, "if two segments from a exterior point are tangent to the circle, then they are congruent".

Since, AT and AR from an exterior point A are tangents to the circle, then AT and AR are congruent.

Thus, we have;

[tex]AT=AR[/tex]

[tex]AT=35[/tex]

Thus, the length of AT is 35 units.

Perimeter of AGN:

The perimeter of AGN is given by

[tex]\triangle AGN=AR+RG+GE+EN+TN+AT[/tex]

Substituting the values, we get;

[tex]\triangle AGN=35+21+21+19+19+35[/tex]

[tex]\triangle AGN=150[/tex]

Thus, the perimeter of the triangle AGN is 150 units.

Answer:

150

Step-by-step explanation:

Segment AE divides the triangle into two congruent right angle triangles

AG = AN = 35 + 21 = 56

NG = 2(19) = 38

Perimeter = 56 + 56 + 38

Step-by-step explanation:

This is a simple sequence, and they are asking only for the third number in the sequence, so repeated subtraction using is the optimal method for solving for the final answer.

First start with the first term in the sequence, which is 38. The next term is found by subtracting 7.

2nd term = 1st term - 7 (original equation)

2nd term = 38 - 7 (substitute values)

2nd term = 31 (combine like terms by subtracting)

Then repeat this process to find the third term.

3rd term = 2nd term - 7 (original equation)

3rd term = 31 - 7 (substitute values)

3rd term = 24 (combine like terms by subtracting)

Therefore the third term is 24.

Answer:

the coordinates of B is (-5,7)

The coordinates of the other end of the line segment, point B, are calculated by rearranging the midpoint formula and substituting the given values, resulting in B = (-5,7).

In mathematics, the midpoint of two points, A and B, can be calculated using the midpoint formula: ((x1 + x2) / 2, (y1 + y2) / 2). In this case, you are given the midpoint, M, and one of the points, A, and asked to find the other point, B. Given that M is (-3,2) and A is (-1,-3), you can rearrange the midpoint formula to solve for B: ((2 * xm - xA), (2 * ym - yA)).

Substitute the given values into this equation and you get B = ((2 * -3 - -1), (2 * 2 - -3)). Then perform the operations to find that B = (-6+1, 4+3) which simplifies to B = (-5,7).

The experimental probability that the spinner does not land on red is 12/17.

The question asks to find the experimental probability that a spinner does not land on red. To find this, we add the number of times the spinner landed on colors other than red and divide that sum by the total number of spins. In the given experiment, the spinner landed on purple 11 times and on yellow 13 times. Therefore, the total number of non-red outcomes is 11 (purple) + 13 (yellow) = 24.

The total number of spins is the sum of red, purple, and yellow outcomes: 10 (red) + 24 (non-red) = 34. The experimental probability of not landing on red is the number of non-red outcomes divided by the total number of spins, which gives us 24/34, which simplifies to 12/17.

Final answer:

The experimental probability that the spinner does not land on red is ⅔ or 12/17.

Explanation:

The question asks to find the experimental probability that the spinner does not land on red. To calculate this, we need to consider the total number of spins and the number of times the spinner did not land on red.

In this experiment, there were 10 instances of landing on red, 11 on purple, and 13 on yellow. To find the total number of spins, we add these together:

10 (red) + 11 (purple) + 13 (yellow) = 34 total spins

Now, to find the number of spins that did not land on red, we only consider the purple and yellow ones:

11 (purple) + 13 (yellow) = 24 non-red spins

The experimental probability is the number of non-red spins over the total number of spins:

Experimental probability = number of non-red spins / total number of spins = 24/34

To simplify this fraction, we divide both the numerator and the denominator by the greatest common factor, which is 2 in this case:

24 ÷ 2 = 12
34 ÷ 2 = 17

So, the probability in simplest form is:

Experimental probability = 12/17

Answer:

Base of quilt is 8 inch.

Step-by-step explanation:

Refer to the attachment.

Given that pattern on the quilt is right angle triangle. Consider ΔABC as right angle triangle where ∠ABC=90°.

Given that area of triangle is 24 in² and height is 6 inch that is, AB = 6 inch.

To find the base use formula for area of right angle triangle.

[tex]Area\:of\:triangle=\dfrac{1}{2}\times base\times height[/tex]

Substituting the values,

[tex]24=\dfrac{1}{2}\times base\times 6[/tex]

Simplifying,

[tex]24=\dfrac{6}{2}\times base[/tex]

Multiplying both sides by [tex]\dfrac{2}{6}[/tex],

[tex]24\times \dfrac{2}{6}=\dfrac{6}{2}\times base\times \dfrac{2}{6}[/tex]

Simplifying,

[tex]24\times \dfrac{2}{6}=base[/tex]

Dividing the numbers,

[tex]8=base[/tex]

Therefore, length of base of each quilt piece is 8 inch.
