Answer:

V = 400

Step-by-step explanation:

The volume (V) of the pyramid is

V = [tex]\frac{1}{3}[/tex] area of base × perpendicular height (h)

Consider a right triangle from the vertex to the midpoint of the base across to the slant height, with hypotenuse of 13

Using Pythagoras' identity on the right triangle, then

h² + 5² = 13²

h² + 25 = 169 ( subtract 25 from both sides )

h² = 144 ( take the square root of both sides )

h = [tex]\sqrt{144}[/tex] = 12

Area of square base = 10² = 100, thus

V = [tex]\frac{1}{3}[/tex] × 100 × 12 = 4 × 100 = 400

By the law of sines,

[tex]\dfrac{\sin m\angle A}a=\dfrac{\sin m\angle B}b\implies\sin m\angle B=\dfrac{33.7\sin75^\circ}{51.2}[/tex]

We get one solution by taking the inverse sine:

[tex]m\angle B=\sin^{-1}\dfrac{33.7\sin75^\circ}{51.2}\approx39^\circ[/tex]

In this case there is no other solution!

To check: suppose there was. The other solution is obtained by recalling that [tex]\sin(180-x)^\circ=\sin x^\circ[/tex] for all [tex]x[/tex], so that

[tex]180^\circ-m\angle B=\sin^{-1}\dfrac{33.7\sin75^\circ}{51.2}\implies m\angle B\approx141^\circ[/tex]

But remember that the angles in any triangle must sum to 180 degrees in measure. This second "solution" violates this rule, since two of the known angles exceed 180: 75 + 141 = 216 > 180. So you're done.

This triangle is not a right triangle. How do we solve this then? You will use the law of sine with is shown below:

[tex]\frac{sin A}{a} =\frac{sin B}{b} = \frac{sinC}{c}[/tex]

What we know is shown in the image attached below:

Plug what you know into the law of sine

[tex]\frac{sin75}{51.2} =\frac{sinB}{33.7}[/tex]

To solve for sinB cross multiply

sin75*33.7 = sinB * 51.2

32.55 = sinB*51.2

Divide 51.2 to both sides to isolate sinB

32.55 / 51.2 = sinB / 51.2

0.63577 = sinB

To find B you must use arcsin:

[tex]sin^{-1} 0.63577[/tex]

39.477

^^^This is your rough estimate but you can simply keep it to 39 degrees

This means that your answer is correct!

Hope this helped!

Answer:

x = 36

Step-by-step explanation:

The angles 3x - y and 2x + y form a straight angle and are supplementary, so

3x - y + 2x + y = 180

5x = 180 ( divide both sides by 5 )

x = 36

-----------------------------------------------

5y and 3x - y are vertical angles and congruent, hence

5y = 3x - y ( add y to both sides )

6y = 3x ← substitute x = 36

6y = 3 × 36 = 108 ( divide both sides by 6 )

y = 18

To calculate the conditional probability, we need to find the probability of transferring two red balls and two blue balls from Bowl I to Bowl II and the probability of selecting a blue ball from Bowl II which is 0.0923

To calculate the conditional probability, we need to find the probability of transferring two red balls and two blue balls from Bowl I to Bowl II and the probability of selecting a blue ball from Bowl II.

First, we calculate the probability of transferring two red balls and two blue balls from Bowl I to Bowl II. There are 14 balls in Bowl I, so the probability of transferring a red ball on the first draw is 8/14. After transferring one red ball, there are now 13 balls in Bowl I, so the probability of transferring another red ball is 7/13. Similarly, the probability of transferring a blue ball on the first draw is 6/14, and the probability of transferring another blue ball is 5/13. To find the overall probability, we multiply these probabilities: (8/14) * (7/13) * (6/14) * (5/13).

Next, we calculate the probability of selecting a blue ball from Bowl II. After transferring four balls from Bowl I, there are now 10 balls in Bowl II, with 6 blue balls. The probability of selecting a blue ball is therefore 6/10.

Finally, we calculate the conditional probability by dividing the probability of transferring two red balls and two blue balls from Bowl I to Bowl II by the probability of selecting a blue ball from Bowl II:

= (8/14) * (7/13) * (6/14) * (5/13) / (6/10)

= 0.0923 (rounded to four decimal places).

Step-by-step explanation:

for the each year, the interest is increased by 2%,

so after 1 year, earned interest is 2% of $400

=2/100 × 400=$8

so the earned balance is $(400+8)=$408

so after 2 year, earned interest is 2% of $408

=2/100 × 408=$8.16

so the earned balance is $(408+8.16)=$416.16

after 3 year, earned interest is 2% of $416.16

=2/100 × 416.16=$8.32

so the earned balance is $(416.16+8.32)=$424.48

after 4 year, earned interest is 2% of $424.48

=2/100 × 424.48=$8.48

so the earned balance is $(424.48+8.48)=$480.48

after 5 year, earned interest is 2% of $480.48

=2/100 × 480.48=$9.6

so the earned balance is $(480.48+9.6)=$490.08

after 6 year, earned interest is 2% of $490.08

=2/100 × 490.08=$9.8

so the earned balance is $(490.08+9.8)=$499.88

therefore the interest earned after 6 years is

$(8+8.16+8.32+8.48+9.6+9.8)=$52.36

and the balance after 6 years is $499.88

Answer:

(x - 3)² + (y - 2)² = 17

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

here (h, k) = A(3,2), thus

(x - 3)² + (y - 2)² = r²

The radius is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 1, 1) ← point on circle

r = [tex]\sqrt{(-1-3)^2+(1-2)^2}[/tex] = [tex]\sqrt{(-4)^2+(-1)^2}[/tex] = [tex]\sqrt{17}[/tex]

Hence r² = ([tex]\sqrt{17}[/tex] )² = 17

(x - 3)² + (y - 2)² = 17 ← equation of circle

Answer:

1.2 cm

Step-by-step explanation:

Quadrilateral circumscribing a circle is a quadrangle whose sides are tangent to a circle inside it (see attached diagram).

The area of circumscribed quadrilateral is

[tex]A=p\cdot r,[/tex]

where [tex]p=\dfrac{a+b+c+d}{2}[/tex] is semi-perimeter and r is radius of inscribed circle.

In your case, [tex]A=12\ cm^2[/tex]

If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so

[tex]a+c=b+d=10\ cm,[/tex]

so

[tex]P=10+10=20\ cm\\ \\p=\dfrac{20}{2}=10\ cm[/tex]

Now

[tex]12=10\cdot r\Rightarrow r=\dfrac{12}{10}=1.2\ cm[/tex]

Hello there!

Answer:

The slope is 9, and the y-intercept is –2

Step-by-step explanation:

The equation is y = 9x - 2

This follows the equation y = mx + b

Where as:

m = slope

b = y-intercept

When you know this, you would figure out that 9 is in the same place as m, and -2 is in the same place as b.

The y-intercept would not be a positive 2 because when there's a minus sign next to the number in the y-intercept spot, then you would have to bring that over to the number. We can also say the minus sign belongs to the 2, making it a -2.

With the information we know now, we can say that the slope of the equation is 9, and the y-intercept would be -2.

Therefore, giving your answer as "The slope is 9, and the y-intercept is –2"

Final answer:

The slope of the linear function represented by y=9x-2 is 9, and the y-intercept is -2. This is determined by comparing the equation to the slope-intercept form y = mx + b.

Explanation:

The slope and y-intercept of the linear function represented by the equation y=9x-2 can be identified by comparing it to the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. In the given equation, 9 is the coefficient of x, which means it is the slope of the line. The constant term, -2, is the y-intercept because it indicates the point at which the line crosses the y-axis.

Answer:

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Explanation:

We are given that:

Erin planted t tomato plants

Leo planted 5 fewer tomato plants than Erin, this means that:

Leo planted = t - 5 tomato plants

Fillip planted 10 fewer tomato plants than Erin, this means that:

Fillip planted = t - 10 tomato plants

Now, we want to find the total number of tomato plants

This means that we will add the number of plants planted by Erin, Leo and Fillip

Therefore:

Total number of plants = t + t - 5 + t - 10

Total number of plants = 3t - 15 = 3(t-5) tomato plants

Hope this helps :)

Final answer:

The expression that represents the total number of tomato plants Erin, Leo, and Filipe planted is 3t - 15, where t is the number of plants Erin planted.

Explanation:

If Erin planted t tomato plants, then we can express the number of tomato plants Leo and Filipe planted using algebraic expressions that are based on this initial quantity. Leo planted 5 fewer tomato plants than Erin, so we can describe the number of plants Leo planted as t - 5. Similarly, Filipe planted 10 fewer tomato plants than Erin, and his number can be represented by t - 10.

To find the total number of tomato plants all three of them planted together, you would add these expressions:

Total number of plants = Erin's plants + Leo's plants + Filipe's plants

Total = t + (t - 5) + (t - 10)

Simplify the expression by combining like terms:

Total = t + t - 5 + t - 10

Total = 3t - 15

So the expression that represents the total number of tomato plants Erin, Leo, and Filipe planted in all is 3t - 15.

P and Q are endpoints, so the center of the circle would be the midway point.

A. The midpoint is found using:

(x1 + x2 /2 , y1 +y2 /2)

-10 + 4 = -6 /2 = -3

-2 + 6 = 4 /2 = 2

The center of the circle is at (-3,2)

B) The radius would be the distance from the midpoint to an end point.

Using the distance formula:

√((x2-x1)^2 + (y2-y1)^2)

√(4 - -3^2 + 6-2^2)

√(7^2 + 4^2)

√(49+16)

√65

C) Using the circle equation form of (x-h)^2 + (y-k)^2 = r^2

H,K is the center point found in part A and r is the radius found in part B.

The equation becomes (x-(-3))^2 + (y -2)^2 = √65^2

Which simplifies to: (x+3)^2 + (y-2)^2 = 65

Answer:

In conclusion, dreams are the driving theme and characterization in the novel. They help explain each character's motivation for the actions they take and the way they feel. All of the characters have a obstacles in their life stopping them from reaching their goal. Authors use dreams to give their characters something to live for and strive for. Without the character's dreams and goals for the future, the characters would have nothing to work towards and they would be much less complex  

A conclusion for an essay on dreams in 'Of Mice and Men' should discuss the portrayal of the elusive American Dream, the use of dreams as a literary device, and the reflection of societal constraints and collective unconscious.

When crafting a conclusion for an essay about the theme of dreams in Of Mice and Men, you must strive to encapsulate the essence of the theme and its impact on the characters and the reader's understanding of the novel's message. The unattainable nature of the American Dream is vividly portrayed through the characters' struggles, symbolizing the universal experience of aspiration and loss. While each character harbors personal ambitions, the novel ultimately reveals the harsh reality of shattered dreams and the perseverance of hope, despite life's unpredictable and often tragic course. Understanding the role of dreams as a literary tool employed by John Steinbeck deepens one’s appreciation for his exploration of the human psyche and the societal constraints of the time period. Dreams in Steinbeck’s work reflect a combination of the characters' inner desires and the collective unconscious that connects them to the broader human experience, as Carl Jung would suggest.

To know which of the products results in a difference of square, we need to remember the difference of squares from:

The difference of squares form is:

[tex](a+b)(a-b)=a^{2}-b^{2}[/tex]

So, discarding each of the given options in order to find which products result in a difference of squares, we have:

[tex](x-y)(y-x)=xy-x^{2}-y^{2} +yx=-x^{2} -y^{2}[/tex]

So, the obtained expression is not a difference of squares.

[tex](6-y)(6-y)=36-6y-6y+y^{2}=y^{2}-12y+36[/tex]

So, the obtained expression is not a difference of squares.

[tex](3+xz)(-3+xz) =(xz+3)(xz-3)=(xz)^{2}-3xz+3xz-(3)^{2}\\\\(xz)^{2}-3xz+3xz-(3)^{2}=(xz)^{2}-(3)^{2}[/tex]

So, the obtained expression is a difference of squares since it matches with the form of the difference of squares.

[tex](y^2-xy)(y^2+xy)=(y^{2})^{2}+y^{2}*xy-y^{2}*xy-(xy)^{2} \\\\(y^{2})^{2}+y^{2}*xy-y^{2}*xy-(xy)^{2}=(y^{2})^{2}-(xy)^{2}[/tex]

So, the obtained expression is a difference of squares since it matches with the form of the difference of squares.

[tex](25x-7y)(-7y+25x)=-175xy+(25x)^{2}+49y^{2}-175xy\\\\-175xy+(25x)^{2}+49y^{2}-175xy=(25x)^{2}+49y^{2}-350xy[/tex]

So, the obtained expression is not a difference of squares

[tex](64y^2+x^2)(-x^2+64y^2)=(64y^2+x^2)(64y^2-x^2)\\\\(64y^2+x^2)(64y^2-x^2)=(64y^{2})^{2} -(x^{2}*64y^{2})+(x^{2}*64y^{2})-(x^{2})^{2}\\ \\(64y^{2})^{2} -(x^{2}*64y^{2})+(x^{2}*64y^{2})-(x^{2})^{2}=(64y^{2})^{2}-(x^{2})^{2}[/tex]

So, the obtained expression is a difference of squares since it matches with the form of the difference of squares.

Hence, the products that result in a difference of squares are:

C) [tex](3+xz)(-3+xz)[/tex]

D) [tex](y^2-xy)(y^2+xy)[/tex]

F) [tex](64y^2+x^2)(-x^2+64y^2)[/tex]

Have a nice day!

5 feet 6 inches is equal to ((5*12)+6) inches, which is equal to 66 inches since 5*12=60 and 60+6=66

2 feet 9 inches is equal to ((2*12)+9) inches, which is equal to 33 inches since 2*12=24 and 24+9=33

Since 66 and 33 are the length and width (there isn't any specific order as to which measurement is the length or width) and the question is asking for square inches,(which is the area) so what needs to be done next is 66*33, which equals 2178, the square inches of plastic needed is 2718 square inches.

I couldn't keep the answer in the format of _ft _in because they are asking for the area in inches, and I don't think it would be smart to convert inches to decimal values of feet for reasons I won't talk about.

So yeah, your answer is 2178 square inches of plastic.

Answer:

  10.24 square feet

Step-by-step explanation:

The area of one triangular face is ...

  A = (1/2)bh = (1/2)(0.8 ft)(6 ft) = 2.4 ft²

Then the four triangular faces will have a total area of ...

  lateral area = 4·(2.4 ft²) = 9.6 ft² . . . . . sufficient to help you choose the correct answer

__

The area of the square base is the square of the side length:

  base area = (0.8 ft)² = 0.64 ft²

Then the total surface area is ...

  surface area = lateral area + base area

  surface area = 9.6 ft² + 0.64 ft² = 10.24 ft²

You would multiply the Area of a square which is B x H the Area for the square is 0.8 x 0.8 = 0.64

Then you multiply the Area of a triangle and the Area of a triangle is B x H divided by 2  and so you multiply the number of triangles there are which is 0.8 x 6 = 4.8 then divide that by 2 which is 2.4 then multiply that with the number of triangles we have all together. there are 4 triangles.

Multiply 2.4 x 4 = 9.6 then add the Area of the square which is 0.64 + 9.6 and the answer is 10.24  

Hope this helps
