Answer:

If two pyramid have the same height , for volume to be the same the base area of the pyramids should be equal

Step-by-step explanation:

Volume of a pyramid is given by;

[tex]V=l*w*h /3[/tex]

where l is length of base, w is width of base, and h is height of base

If two pyramid have the same height , for volume to be the same the base area of the pyramids should be equal

The base area= l×w

For example if we have two pyramids A and B with the following properties;

A= height= x , length=l₁ and width = w₁

B= height=x, length=l₂ and width = w₂

Then the volume of the two pyramid will be the same if;

l₁*w₁=l₂*w₂

Thus

V₁= (l₁*w₁*x )/3  = (l₂*w₂*x)/3

For two pyramids with the same height to have the same volume, they must have bases with equal areas.

The volume [tex]\( V \)[/tex] of a pyramid can be calculated using the formula:

[tex]\[ V = \frac{1}{3} \times \text{base area} \times \text{height} \][/tex]

Given that the height [tex]\( h \)[/tex] is the same for both pyramids, the volume formula simplifies to:

[tex]\[ V = \frac{h}{3} \times \text{base area} \][/tex]

For the volumes [tex]\( V_1 \)[/tex] and [tex]\( V_2 \)[/tex] of the two pyramids to be equal, the following equation must hold:

[tex]\[ \frac{h}{3} \times \text{base area}_1 = \frac{h}{3} \times \text{base area}_2 \][/tex]

Since the height [tex]\( h \)[/tex] is constant for both pyramids, it can be cancelled out from both sides of the equation:

[tex]\[ \text{base area}_1 = \text{base area}_2 \][/tex]

Therefore, the bases of the two pyramids must have equal areas to ensure that they have the same volume, given that they have the same height.

Answer:

m = 12f

Or

m/12 = f

Step-by-step explanation:

The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.

As we know,

1 foot = 12 inches

Given in the question:

m = measurement in inches

and

f= measurement in feet

Hence the equation will be:

m = 12f

Or

m/12 = f ..

Equations would you use the zero product property on is (x-5)(x-10)=0

The zero product property states that if a⋅b=0 then either a or b equal zero.

To get the positive value we have consider those factor which have negative in their expression.

As, by the property if we equate both of them equal to zero one by one then we get the desired value.

Answer: 60

Step-by-step explanation:

A circle is 360 degrees, so 360/6 is your answer.

Answer: 29 degrees is the answer

Step-by-step explanation:

The bisector is the line that divides the angle, and rhombus diagonally. So, basically you're just dividing 58 in half. Which is 29 degrees.

The measure of each of the two angles formed by the bisector of the diagonal of a rhombus will be 29 degree.

Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

We have,

A Rhombus with one of its angle equal to 58°.

Now,

Bisector of an angle, divides an angle into two equal parts.

So,

From the above mentioned definition,

i.e.

[tex]=\frac{58}{2} = 29^0[/tex]

So, the measure of each angle is 29°.

Hence, we can say that the measure of each of the two angles formed by the bisector of the diagonal of a rhombus will be 29 degree.

Answer:

x+3x+5=101 (Option C).

Step-by-step explanation:

This question requires to be solved using the supposition method.

Let Aylen's savings be $x. Therefore, Rich's savings would be $(3x+5). This is because it is mentioned that Rich has $5 more than 3 times the amount of money Aylen has. The sum of the savings is $101. Therefore the sum of the savings of Aylen and Rich is given by:

x + 3x + 5 = 101. Thus, Option C is the correct answer.

Solve the equation for x gives x = $24. This is Aylen's share. To calculate Rich's share, simply put x=24 in 3x+5. Thus, Rich's share will be $77.

In short, Rich's share = $77, Alan's share = $24, and this has been calculated using the equation x+3x+5=101 (Option C)!!!

Answer:The last experimental design is the best of the options: 'Compare the average number of

tomatoes that are produced by 10 tomato plants that are grown in clay soil to

the average number of tomatoes that are produced by 10 tomato plants that are

grown in sandy soil''.

The first two experimental designs measure the growth of

tomato plants, which is not necessarily related to the yield of tomatoes. The

third experimental design compares the tomato yield of the two

soils with only one plant grown in each soil. Obviously, the result obtained

from this experiment would be statistically weak. The last experimental design

compares tomato yield and also uses a larger number of plants in each soil

type, so the results obtained would be of slightly greater statistical

significance.

Step-by-step explanation:

The mean absolute deviation is M = 2.2

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the total number of plants be n

Now , the value of n = 10

And , the number of tomatoes on each plant is given by set A

Now , the value of set A = { 5 , 5 , 5 , 6 , 9 , 10 , 10 , 10 , 10 , 10 }

So , the total number of tomatoes = 5 + 5 + 5 + 6 + 9 + 10 + 10 + 10 + 10 + 10

The total number of tomatoes = 80 tomatoes

Now , the mean number of tomatoes = 80 / 10 = 8

And , the mean deviation is M

where M = 1/10 [ ( 8 - 5 ) + ( 8 - 5 ) + ( 8 - 5 ) + ( 8 - 6 ) + | ( 8 - 9 ) | + 5( 10 - 8 )

M = ( 1/10 ) [ 3 + 3 + 3 + 2 + 1 + 5 ( 2 ) ]

M = ( 1/10 ) [ 22 ]

M = 2.2

Therefore , the value of M is 2.2

Hence , the mean deviation is 2.2

Answer:

Step-by-step explanation:

All marbles here are identical. Also, the question isn't concerned about the order in which the marbles are drawn. Thus, all calculations here shall be combinations rather than permutations.

How many ways to choose three out of six identical red marbles without replacement?

[tex]\displaystyle _6C_3 = c(6, 3) = {6\choose 3} = 20[/tex].

Note that these three expressions are equivalent. They all represent the number of ways to choose 3 out of 6 identical items without replacement.

How many ways to choose three out of all the 6 + 10 + 6 = 22 marbles?

[tex]\displaystyle _{22} C_{3} = 1540[/tex].

The probability of choosing three red marbles out of these 22 marbles will be:

[tex]\displaystyle \frac{\text{Number of ways for choosing three out of six red marbles}}{\text{Number of ways to choose three out of 22 marbles}} = \frac{20}{1540} = \frac{1}{77}[/tex].

How many ways to choose two out of six identical red marbles without replacement?

[tex]\displaystyle _6 C_2 = 15[/tex].

How many ways to choose one out of 10 + 6 = 16 non-red marbles?

[tex]_{16} C_1=16 [/tex].

Choosing two red marbles does not influence the number of ways of choosing a non-red marble. Both event happen and are independent of each other. Apply the product rule to find the number of ways of choosing two red marbles and one non-red marble out of the pile of 22.

[tex]_6 C_2 \cdot _{16} C_1= 240[/tex].

Probability:

[tex]\displaystyle \frac{240}{1540} = \frac{12}{77}[/tex].

Double check that the order doesn't matter here.

None of the marbles are red. In other words, all three marbles are chosen out of a pile of 10 + 6 = 16 white and blue marbles. Number of ways to do so:

[tex]_{16} C_{3} = 560[/tex].

Probability:

[tex]\displaystyle \frac{560}{1540}= \frac{4}{11}[/tex].

Answer:

A) 1/77; B) 12/77; C) 4/11

Step-by-step explanation:

A) There are a total of 22 marbles.  6 of them are red.

On the first draw, the probability of getting a red marble is 6/22.

On the second draw, there's one less red marble and one less marble total, so the probability of getting another red marble is 5/21.

Similarly, on the third draw, the probability of getting a red marble is 4/20.

So the probability that all three draws are red marbles is:

P = (6/22) (5/21) (4/20)

P = 1/77

Another way this can be calculated is with combinations:

P = (ways to choose 3 red marbles from 6) / (ways to choose 3 marbles from 22)

P = ₆C₃ / ₂₂C₃

P = 20 / 1540

P = 1/77

B) The same logic can be repeated here.  Using the first method, if the first two selection are red:

P = (6/22) (5/21) (16/20) = 4/77

If the first and third are red:

P = (6/22) (16/21) (5/20) = 4/77

If the last two are red:

P = (16/22) (6/21) (5/20) = 4/77

So the total probability is:

P = 4/77 + 4/77 + 4/77

P = 12/77

Using the second method:

P = (ways to choose 2 red from 6) × (ways to choose 1 non-red from 16) / (ways to choose 3 from 22)

P = ₆C₂ ₁₆C₁ / ₂₂C₃

P = 15 × 16 / 1540

P = 12/77

C)

Same logic:

P = (16/22) (15/21) (14/20)

P = 4/11

Or:

P = ₁₆C₃ / ₂₂C₃

P = 560 / 1540

P = 4/11

Answer:

lcm = 4

Step-by-step explanation:

20 = 2 × 2 × 5 ← product of prime factors

12 = 2 × 2 × 3 ← product of prime factors

The lowest common multiple (lcm) = 2 × 2 × 5 × 3 = 60

Answer:

60

Step-by-step explanation:

First, break down each of the numbers into their prime factors.

20 = 2² x 5

12 = 2² x 3

To find the LCM, underline each of the prime numbers. If there is a repeated prime number, underline the one with the largest possible value. For example, if there is 3² and 3³, underline the second one. In this case, the values are the same, so just underline one.

20 = 2² x 5

12 = 2² x 3

Next, multiply all the underlined numbers.

LCM (20, 12) = 2² x 5 x 3 = 60

r(5)=3.05

t(5)=3(5)

t(5)=15

For this case we give as data the following equation:

[tex]4x + 12 = 48[/tex]

Where "x" represents the cost of a ticket.

By clearing the value of "x" of the equation we can know the cost of a ticket.

If we subtract 12 from both sides of the equation, we have:

[tex]4x = 48-12\\4x = 36[/tex]

If we divide between 4 on both sides of the equation:

[tex]x = \frac {36} {4}\\x = 9[/tex]

Therefore, the cost of a ticket is $ 9.00

C' = (-6, -5)

Step-by-step explanation:

We are given that a triangle ABC is reflected over the line y = x.

Given the points of the vertices of the triangle ABC to be (-6, -1) (-2, -1) and (-5, -6) respectively, we are to determine the coordinates of C'.

When reflected over the line y = x, the x and y coordinates exchange their place.

(x, y) ---> (y, x)

Therefore, if C = (-5,-6) then C' = (-6, -5).

Answer:

[tex]\boxed{(-6,-5)}}[/tex]

Given a quadratic in standard form : ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

x² - 10x + 21 ← is in standard form

with a = 1, b = - 10, so

[tex]x_{vertex}[/tex] = - [tex]\frac{-10}{2}[/tex] = 5

Substitute x = 5 into the quadratic for the corresponding value of y

y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4

vertex = (5, - 4)
