Answers

Answer 1
Problem A
You are given that CB = 271 feet. You are also given that <CAB = 30 degrees.

So you can use Sin(<CAB) = opposite / hypotenuse or
hypotenuse = opposite / sin(<CAB)
hypotenuse = 271 / 0.5
hypotenuse (AB) = 542 feet.

Problem B
CD = 772 feet           Given in table
<ACD = 74o              Given on drawing.

We need to find AC which is not given
Cos 30 = adjacent / hypotenuse.
adjacent = hypotenuse * Cos(30)
adjacent = AB * Cos(30)
Adjacent = 542 * cos(30)
Adjacent = AC = 469.4 feet

Now we need to start again
AC = 469.4
<ACD = 74
CD = 772
AD = ???

AD^2 = AC^2 + CD^2 - 2 * AC * CD * Cos(74)
AD^2 = 595984 + 220336.4 - 399538 
AD^2 = 416782.1
AD = sqrt(416782.1)
AD = 645.59

Problem 3
I'll set it up for you. And give you the answer I get, but I'm going to leave it to you mostly. It just follows what I've done above.

DC = 645.59
CE = 561
DE = 543

DC^2 = CE^2 + DE^2 - 2* CE * DE * Cos(E)
645.59^2 = 561^2 + 543^2 - 2*561*543 * Cos(E)
Cos(E) = -0.3164
E = cos-1(0.3164)
E = 108.45 degrees.

A rectangular photograph is mounted on a poster and has a two inch border on each side. The poster itself is mounted on a frame whose sides are the same length as the sides of the poster. The frame cost $2 per inch and the cost of the frame was $160. If the area of the photograph is 231 inches squared. What are the dimensions of the frame?

Answers

Let's define variables:
 w: width of the photograph
 l: length of the photograph
 The cost of the box is:
 2 * (2 * (w + 2)) + 2 * (2 * (l + 2)) = 160
 The area is:
 (w + 2) * (l + 2) = 231
 Solving the system of equations we have:
 w = 5 inches
 l = 31 inches
 Then, the dimensions of the frame are:
 w + 2 = 7 inches
 l + 2 = 33 inches

Lincoln Technical College has 856 students. They expect 700 guests for a special speaker. The custodian has set up 1,500 chairs. How many more chairs are needed if everyone is to have a seat? 3. Draw a picture or a chart that shows the information and the question

Answers

2,568 I Think , Sorry If I’m Wrong

57 chairs are needed if everyone is to have a seat

To calculate the number of additional chairs needed, we first need to determine the total number of seats required. This is the sum of the students, guests, and speaker. Then, we subtract the number of chairs already set up to find out the additional chairs needed.

Let's break it down step by step:

1. Total number of seats required:

  - Students: 856

  - Guests: 700

  - Speaker: 1 (assuming the speaker needs a seat)

  Total seats required = 856 (students) + 700 (guests) + 1 (speaker) = 1,557 seats

2. Number of chairs already set up: 1,500

3. Additional chairs needed:

  Total seats required - Chairs already set up = 1,557 - 1,500 = 57

So, Lincoln Technical College needs 57 more chairs to accommodate everyone if all students, guests, and the speaker are to have a seat.

Lincoln Technical College has 856 students and expects 700 guests for a special speaker, making the total number of attendees 1,557. The custodian has already set up 1,500 chairs. To find out how many more chairs are needed, we subtract the number of chairs already set up from the total seats required. This calculation reveals that 57 additional chairs are needed to ensure that everyone has a seat. It's essential to consider all attendees, including students, guests, and the speaker, to accurately determine the total seating requirements.

Larry's lemons is a street vendor business that sells lemonade and lemon bars. A cup of lemonade sells for $2 and a lemon bar sells for $1.50. When all related business expenses are included, a cup of lemonade costs $0.25 to prepare and a lemon bar costs $0.20 to prepare. Last Monday, one of the vendors selling Larry's Lemons sold at least $500 worth of lemonade and lemon bars and its expenses were no more than $100. At least 150 cups of lemonade were sold. Let x be the number of cups of lemonade sold last Monday and y be the number of lemon bars sold last Monday. Which ordered pair representing a combination of cups of lemonade and lemon bars could have been sold last Monday and make sense in the context of the situation?

Answers

The one possible ordered pair that satisfies all conditions is (x, y) = (150, 134).

The ordered pair (x, y) that satisfies the following conditions:

1. The total revenue from selling x cups of lemonade and y lemon bars is at least $500. This gives us the inequality:

[tex]\[ 2x + 1.50y \geq 500 \][/tex]

2. The total expenses for preparing x cups of lemonade and y lemon bars is no more than $100. This gives us the inequality:

[tex]\[ 0.25x + 0.20y \leq 100 \][/tex]

3. At least 150 cups of lemonade were sold, which gives us the inequality:

[tex]\[ x \geq 150 \][/tex]

To find a combination of x and y that satisfies all these conditions, we can start by considering the minimum number of lemonade cups sold, which is 150. We can then calculate the revenue and expenses for this minimum number and see how many lemon bars would be needed to meet the revenue requirement while keeping the expenses within the limit.

Let's start with the minimum number of lemonade cups:

[tex]\[ x = 150 \][/tex]

The revenue from lemonade alone would be:

[tex]\[ 2 \times 150 = \$300 \][/tex]

The expenses for lemonade alone would be:

[tex]\[ 0.25 \times 150 = \$37.50 \][/tex]

Now, we need to find out how many lemon bars (y) would be needed to make up the remaining revenue to at least $500 while keeping the total expenses at or below $100.

Let's denote the remaining revenue needed as R and calculate it:

[tex]\[ R = 500 - 300 = \$200 \][/tex]

The revenue from selling y lemon bars is $1.50y, so we have:

[tex]\[ 1.50y \geq 200 \][/tex]

[tex]\[ y \geq \frac{200}{1.50} \][/tex]

[tex]\[ y \geq 133.33 \][/tex]

Since we cannot sell a fraction of a lemon bar, we round up to the nearest whole number, so at least 134 lemon bars must be sold.

Now let's check the expenses for the lemon bars. We have $100 - $37.50 = $62.50 left for expenses. The cost to prepare each lemon bar is $0.20, so we calculate the maximum number of lemon bars (y) that can be prepared with the remaining expenses:

[tex]\[ 0.20y \leq 62.50 \][/tex]

[tex]\[ y \leq \frac{62.50}{0.20} \][/tex]

[tex]\[ y \leq 312.5 \][/tex]

Combining the two conditions for y, we find that y must be at least 134 but no more than 312.

Therefore, one possible ordered pair that satisfies all conditions is (x, y) = (150, 134). This means that at least 150 cups of lemonade and at least 134 lemon bars were sold last Monday to meet the revenue and expense conditions.

c. 95% of the population jog between 15% and 21% of the time.
d. we can be 3% confident that the sample result is true.
e. if gallup took many samples, 95% of them would find that exactly 18% of the people in the sample jog.

Answers

Final answer:

The ±3 percent represents the margin of error in the Gallup poll, indicating the potential variation in the poll results due to sampling. The percentage of people who jog regularly could be as low as 15% or as high as 21%.

Explanation:

The ±3 percent represents the margin of error in the Gallup poll. The margin of error is a measure of the uncertainty or potential variation in the poll results due to the sampling process. In this case, it means that the percentage of people who say they jog regularly could be as low as 15% or as high as 21%.

We have been given an equation [tex]2x^2+3x-7=x^2+5x+39[/tex]. We are asked to find the solution for our given equation.

[tex]2x^2+3x-7=x^2+5x+39[/tex]

[tex]x^2+3x-5x-7-39=5x-5x+39-39[/tex]

[tex]x^2-2x-46=0[/tex]

Using quadratic formula, we will get:

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-46)}}{2(1)}[/tex]

Answers

To simplify the given expressions into one fraction, we find a common denominator for each set of fractions, adjust the numerators accordingly, and then combine the numerators over the common denominator.

To simplify the given expressions into one fraction, we need to find a common denominator and combine the fractions accordingly. Let's go through each expression step by step.

For the expression 7/x-3 + 3/x-5, the common denominator would be (x-3)(x-5). We need to multiply each fraction by the denominator that it's missing to get common denominators, and then sum the numerators over the common denominator.

The expression -5/x-3 - (-4)/(x+2) involves subtracting fractions. To simplify, we again find a common denominator, which is (x-3)(x+2), and proceed similarly to the first expression.

For 6/x+7 - 3/x-2, the common denominator is (x+7)(x-2). We perform the same process of equating denominators and combining.

To illustrate with the first expression:
(7(x-5))/((x-3)(x-5)) + (3(x-3))/((x-3)(x-5)) = (7x - 35 + 3x - 9)/((x-3)(x-5))

Combine the numerators to get a single fraction:

(10x - 44)/((x-3)(x-5))

Apply the same approach to the other two expressions to get them into a single fraction form.

31. Whats the maximum vol. of a square pyramid that can fit inside a cube with a side length of 24 cm?

A.2,304 B.4,608 C.6,912 D.13,824

Answers

r = m - v + 2, where r = faces, v = vertices, and m = edges

r = 28 - 13 + 2
r = 15 + 2
r = 17, so the first answer is correct.

7. The surface area of a cone is A = pi*r*sqrt(r^2 + H^2)

A = pi*(7)(sqrt(49 + 1849)
A = pi*(7)(43.57)
A = pi*305 = 959 m^2, so the first answer is correct.

13. The volume of the slab is V = HLW
V = (5 yards)(5 yards)(1/12 yards)
V = 25/12 cubic yards

So it costs $46.00*(25/12) = $95.83 of total concrete. The third answer is correct.

21. First, find the volume of the rectangular prism. V = HLW
V = (15 cm)(5 cm)(7 cm)
V = 525 cm^3

Next, find the volume of the pyramid. V = 1/3(BH), where H is the height of the pyramid and B is the area of the base of the pyramid. Note that B = (15 cm)(5 cm) = 75 cm^2

V = (1/3)(75 cm^2)(13 cm)
V = 325 cm^3

Add the two volumes together, the total volume is 850 cm^3. The fourth answer is correct.

22. The volume of a square pyramid is V = 1/3(S^2)(H), where S is the side length and H is the height.

V = (1/3)(20^2 in^2)(21 in)
V = 2800 in^3

Now that we know the volume of this pyramid, and that both pyramids have equal volume, we plugin our V to the equation for the volume.

2800 = (1/3)(84)(S^2)
2800 = 28S^2
100 = S^2
10 in = S, so we have a side length of 10 in, and the first answer is correct.

The missing number using Euler's formula is: Option A. 17

The maximum volume of a square pyramid is: Option B. 4,608

What is Euler's formula?

"It is a geometrical formula. V − E + F = 2, where V represents number of vertices, E represents number of edges and F represents number of faces."

What is square pyramid?

"Square pyramid is a three dimensional geometrical figure where four triangular sides are associated to square base."

What is cube?

"A cube is a three-dimensional geometric structure with six congruent square face."

Formula for volume of a square pyramid:

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

where [tex]a[/tex] represents the length of square base and [tex]h[/tex] represents the height of the pyramid.

Consider the first question,

number of vertices (V) = 13

number of edges (E) = 28

So, using Euler's formula:

[tex]13-28+F=2[/tex]

⇒ [tex]-15+F=2[/tex]

⇒ [tex]F=2+15[/tex]

⇒ [tex]F=17[/tex]

So, the number of faces are 17.

Hence, the correct answer is option A. 17

Consider last question,

the side length of a cube = 24 cm

As the square pyramid fit inside a cube.

⇒ the length of the square base of a pyramid [tex]b[/tex] = 24 cm

and the height of a square pyramid [tex]h[/tex] = 24 cm

So, the volume of a square pyramid is,

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

⇒ [tex]V=\frac{1}{3}[/tex] × [tex]24^{2}[/tex] × [tex]24[/tex]

⇒ [tex]V= 4608[/tex] [tex]cm^{3}[/tex]

Therefore, the maximum volume of a square pyramid that can fit inside a cube with a side length of 24 cm is [tex]4608[/tex] [tex]cm^{3}[/tex].

b=24, when g=16 and t=2
k=(24*2)/16
k=3
hence:
b=(3g)/2
thus the number of girls when:
b=73 and t=1 will be:
73=(3*g)/1
73=3g
g=73/3
g=24.333~ 24 girls

To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, measures the angle of elevation to the top of the pole to be 26. to the nearest foot, what is the height of the pole

Answers

Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
     [tex]tan\:26^{\circ} =\frac{AE}{120}[/tex]
So, 
     [tex]AE=120\:tan\:26^{\circ} [/tex]
     [tex]AE=58.53\:[/tex]

Therefore, the overall height of the pole is 
     [tex]AB=58.53+8=66.53\:feet[/tex]

The height of the pole is 66.53 feet

The altitude to the hypotenuse of a right triangle has a length of 12. what could be the lengths of the two segments of the hypotenuse ?

Answers

the complete question in the attached figure

we know that
The length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse
h²=x*y
where
h is the length of the altitude to the hypotenuse
h=12
x and y are the two segments of the hypotenuse
so
12²=x*y----------> 144=x*y

the lengths of the two segments of the hypotenuse could be
x=6
y=24
x*y=144

the answer is
6 and 24

Find the total area of the regular pyramid.

Answers

check the picture below.

notice, the base of the "square" pyramid, is a square, and it has 4 triangular faces with a base of 2, and a height of √(10).

so the total surface area is the area of the base plus all 4 triangular faces' areas.

[tex]\bf \stackrel{\textit{squarish base}}{(2\cdot 2)}~~~~+~~~~\stackrel{\textit{4 triangular faces}}{4\left[ \cfrac{1}{2}(2)(\sqrt{10}) \right]}[/tex]

Answer:

Area of the regular pyramid = 16.64 square units.

Step-by-step explanation:

Given  : Regular pyramid .

To find: Find the total area of the regular pyramid.

Solution : We have  given that regular pyramid.

Area = 4 ( area of triangle ) + area of base .

Area of the regular pyramid = 4 ( [tex]\frac{1}{2} * base * height + side * side[/tex].

Area of the regular pyramid =  [tex]4(\frac{1}{2}* 2* \sqrt{10}  + 2*2[/tex]

Area of the regular pyramid =   [tex]4( \sqrt{10} ) + 4[/tex]

Area of the regular pyramid =  (4 [tex]( \sqrt{10} ) \+\ 1[/tex].

Area of the regular pyramid = 16.64 square units.

Therefore, Area of the regular pyramid = 16.64 square units.
