Answer:

62.832 mi^2

Step-by-step explanation:

Top and bottom faces : 2^2 x pi = 4pi    4pi x 2 = 8 pi mi^2

Curved Surface Area= pi x diameter x height

= pi x 4 x 3 = 12 pi mi^2

So total SA= 8pi + 12pi = 20 pi mi62 = 62.832 mi^2 (nearest thousanth)

Answer:

SA=62.832 mi^2

Step-by-step explanation:

To find the surface area of a cylinder, you have to use the formula SA=2πrh+2πr^2. This means the surface area will be (2π x (3x2)) + (2π x (2x2)). If I simplify, I get 12π+8π. That's 20π. If I convert, I get approximately 62.8318531. In your case, I round to the nearest thousandth, and my final answer is 62.832.

Answer:

The area is: [tex]69m^2[/tex]

Step-by-step explanation:

Given

[tex]A= \frac{1}{2}(b_1 + b_2) * h[/tex]

[tex]b_1 = 9m[/tex]

[tex]b_2 = 14m[/tex]

[tex]h =6m[/tex]

Required

The area

We have:

[tex]A= \frac{1}{2}(b_1 + b_2) * h[/tex]

This gives:

[tex]A = \frac{1}{2}* (9m + 14m) * 6m[/tex]

[tex]A = \frac{1}{2}* 23m * 6m[/tex]

[tex]A = 69m^2[/tex]

Given:

[tex]MZ\cong PZ[/tex]

[tex]m\angle MFZ=(x+9)^\circ[/tex]

[tex]m\angle PFZ=(2x-1)^\circ[/tex]

To find:

The measure of angle MFZ.

Solution:

In triangles MFZ and PFZ,

[tex]m\angle FMZ\cong \angle FPZ[/tex]           (Right angle)

[tex]MZ\cong PZ[/tex]           (Given)

[tex]FZ\cong FZ[/tex]           (Common side)

[tex]\Delta MFZ\cong \Delta PFZ[/tex]                  (HL congruent postulate)

[tex]\angle MFZ\cong \angle PFZ[/tex]           (CPCTC)

[tex]m\angle MFZ=m\angle PFZ[/tex]

[tex]x+9=2x-1[/tex]

[tex]9+1=2x-x[/tex]

[tex]10=x[/tex]

The value of x is 10.

The measure of angle MFZ is:

[tex]m\angle MFZ=(x+9)^\circ[/tex]

[tex]m\angle MFZ=(10+9)^\circ[/tex]

[tex]m\angle MFZ=19^\circ[/tex]

Therefore, the measure of angle MFZ is 19 degrees.

[tex]3(x - 3) + 8x = 5(2x + 1)[/tex]

Expanding the terms,

[tex]3(x - 3) + 8x = 5(2x + 1) \\ 3x - 9 + 8x = 10x + 5[/tex]

Collecting like terms,

[tex]3x - 9 - 8x = 10x + 5 \\ 3x - 8x - 10x = 5 + 9[/tex]

Evaluating the terms,

[tex]3x - 8x - 10x = 5 + 9 \\ - 15x = 14[/tex]

Divide both sides by -15,

[tex] - 15x = 14 \\ x = - \frac{14}{15} [/tex]

Answer:

it should be 119

Step-by-step explanation:

(7-3) = 4

4^2 = 16

16 x 7 = 112

112 + 7 = 119

Answer: 119

[tex]7+7(x-3)^{2}[/tex]

[tex]7+7(7-3)^{2}[/tex]

[tex]7+7(4)^{2}[/tex]

[tex]7+7(16)[/tex]

[tex]7+112[/tex]

=119

Answer:

the tax amount is $3.7

Step-by-step explanation:

Given that

The price of the sweatshirt is $74

And, there is a 5% tax

So we assume that We need to find out the tax amount

So here the following formula should be used

= Price of the sweatshirt × tax rate

= $74 × 0.05

= $3.7

Hence, the tax amount is $3.7

So the same would be considered and relevant

Answer:

The value of BEF = 36°

Step-by-step explanation:

Given:

Angle AED = 90°

Angle BEF = 3x°

Angle CEF = 54°

Find;

The value of BEF

Computation:

We know that;

Angle AED = Angle BEC (Vertical opposite angle)

So,

Angle AED = Angle Angle BEF + Angle CEF

90 = 3x + 54

3x = 90 - 54

3x = 36

x = 36 / 3

x = 12

The value of BEF = 3x

The value of BEF = 3(12)

The value of BEF = 36°

Answer:

198in³

Step-by-step explanation:

okay, so this is just a volume problem, just break it down into your rectangular prism and your rectangular pyramid, so let's start on the bottom:

(the formula for the volume of a rectangular prism is base x height)

6 x 4.5 = 27

So now we multiply by 5 (the height)

27 x 5 = 135

So we put that aside while we do the pyramid

(this formula is base x height ÷ 3)

So we already have 27 from the rectangle thingy, so:

27 x 7 = 189

189 ÷ 3 = 63

So now we add both of our volumes together:

135 + 63 = 198

So the volume of the figure is 198in³

But in word problem terminology, There is 198in³ in Owen's birdhouse

Given:

In ΔOPQ, m∠Q=90°, m∠O=26°, and QO = 4.9 feet.

To find:

The measure of side PQ.

Solution:

In ΔOPQ,

[tex]m\angle O+m\angle P+m\angle Q=180^\circ[/tex]        [Angle sum property]

[tex]26^\circ+m\angle P+90^\circ=180^\circ[/tex]

[tex]m\angle P+116^\circ=180^\circ[/tex]

[tex]m\angle P=180^\circ -116^\circ[/tex]

[tex]m\angle P=64^\circ[/tex]

According to Law of Sines, we get

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

Using the Law of Sines, we get

[tex]\dfrac{p}{\sin P}=\dfrac{o}{\sin O}[/tex]

[tex]\dfrac{QO}{\sin P}=\dfrac{PQ}{\sin O}[/tex]

Substituting the given values, we get

[tex]\dfrac{4.9}{\sin (64^\circ)}=\dfrac{PQ}{\sin (26^\circ)}[/tex]

[tex]\dfrac{4.9}{0.89879}=\dfrac{PQ}{0.43837}[/tex]

[tex]\dfrac{4.9}{0.89879}\times 0.43837=PQ[/tex]

[tex]2.38989=PQ[/tex]

Approximate the value to the nearest tenth of a foot.

[tex]PQ\approx 2.4[/tex]

Therefore, the length of PQ is 2.4 ft.

Answer:

5 3/4 bakers can make 27.91 pretzels in 1 1/2 hours.

Step-by-step explanation:

Given that 1/3 of 33 bakers can make 89 pretzels in 2 1/2 hours, to determine how many pretzels can 5 3/4 bakers make in 1 1/2 hours the following calculation must be performed:

33 x 1/3 = 11

11 bakers can make 89 pretzels in 2.5 hours, that is, 35.6 per hour (89 / 2.5), and 3,236 per baker per hour (35.6 / 11).

3/4 = 0.75

Therefore, 5.75 bakers, making 3.236 per hour during 1.5 hour, will make the following amount of pretzels:

3.236 x 1.5 x 5.75 = X

4.854 x 5.75 = X

27.91 = X

Therefore, 5 3/4 bakers can make 27.91 pretzels in 1 1/2 hours.

The inequality

The arrow points starts at 6 and points left.

This means that:

To get the answer, we'll use the following property of logs:

logₓ(A) + logₓ(B) = logₓ(A*B)

SImplifying the given expression:

Now, we are given the expression:

log₆36 + log₆216

Using the property listed above, we can rewrite it as:

log₆(36*216)

log₆(7776)

Hence, option (C) is correct

Trinomial

[tex]m^2 - 13m + \frac{169}{4}[/tex]

Binomial squared

[tex](m - \frac{13}{2})^2[/tex]

Step-by-step explanation:

Given

[tex]m^2-13m[/tex]

Required

Make a perfect trinomial

We have:

[tex]m^2-13m =[/tex]

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

Take the coefficient of m i.e. -13

Divide by 2 i.e. -13/2

Square i.e. (-13/2)

Add to both sides of the equation

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

[tex]m^2-13m =[/tex] becomes

[tex]m^2 - 13m + (\frac{-13}{2})^2 = (\frac{-13}{2})^2[/tex]

[tex]m^2 - 13m + \frac{169}{4} = \frac{169}{4}[/tex]

Expand

[tex]m^2 - \frac{13}{2}m- \frac{13}{2}m + \frac{169}{4} = \frac{169}{4}[/tex]

Factorize:

[tex]m(m - \frac{13}{2})- \frac{13}{2}(m - \frac{13}{2}) = \frac{169}{4}[/tex]

Factor out m - 13/2

[tex](m - \frac{13}{2})(m - \frac{13}{2}) = \frac{169}{4}[/tex]

Write as square

[tex](m - \frac{13}{2})^2 = \frac{169}{4}[/tex]

Hence, the trinomial is:

[tex]m^2 - 13m + \frac{169}{4}[/tex]

And the binomial squared is:

[tex](m - \frac{13}{2})^2[/tex]

Solution :

P(A) = 0.2

[tex]$P(B)=0.3$[/tex]

[tex]$P(C)=0.5$[/tex]

Each portfolio has both the stocks and the bonds, and the investors are equally likely to choose either of them.

Let Stock = S

      Bond  = b

Therefore, we have:

[tex]$P(S|A) = 0.5$[/tex]

[tex]$P(b|A) = 0.5$[/tex]

[tex]$P(S|B) = 0.5$[/tex]

[tex]$P(b|B) = 0.5$[/tex]

[tex]$P(S|C) = 0.5$[/tex]

[tex]$P(b|C) = 0.5$[/tex]

Therefore,

[tex]$P(b \text{ and } B)= P(b|B) \times P(B)$[/tex]

                    = 0.5 x 0.3

                    = 0.15

Based on the tree diagram, probability of an investor choosing only bonds from portfolio B is 0.15.

Probability is the chance or likelihood of an event occurring.

Mathematically, probability is given as;

From the tree diagram:

P(A) = 0.2

P(B) = 0.3

P(C) = 0.5

The investors are equally likely to choose from each portfolio.

Each portfolio has both the stocks and the bonds.

Assuming stock = S and Bond = B.

Then;

P(S|A) = 0.5

P(b|A) = 0.5

P(S|B) = 0.5

P(b|B) = 0.5

P(S|C) = 0.5

P(b|C) = 0.5

[tex]P(b \text{ and } B)= P(b|B) \times P(B)[/tex]

[tex]P(b \text{ and } B)= 0.5 \times 0.3 = 0.15[/tex]

Therefore, the probability of an investor choosing only bonds from portfolio B is 0.15.
