A 13 ft ladder is resting on a wall. The angle the ladder makes with the floor is 45 degrees. How high off the ground is the top of the ladder?
Use the function y=13cos(theta) to find the answer
Answers
Answer: 9.19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is distance between the top of the ladder and the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft

Do the boys collide? If so, when do they collide?
Andy and Donald do not collide.
Andy and Donald collide at 4.8 seconds.
Andy and Donald collide at 2.4 seconds.
Andy and Donald collide at 3.6 seconds.
Answers
Answer:
Correct option: second one -> Andy and Donald do not collide.
Step-by-step explanation:
To find if the boys collide, we need to find if there is a common value of t where the their x position are equal and their y position are equal. To do this, we make x(t) of Andy equal to x(t) of Donald, , then if there is a value for t, we do the same for y(t) and check if the values of t are equal:
24 + 23t = 12 + t
22t = -12
t = -0.5455 seconds
As the time is negative, it will not occur, so the boys will never collide.
Correct option: second one

40

salt. How many ounces of each solution should she use?
Answers
Answer:
We need 8 ounces of solution A and 32 ounces of solution B.
Step-by-step explanation:
We are given that a scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt.
She knows that Solution A is 40% salt and Solution B is 65% salt.
First condition states that she wants to obtain 40 ounces of a mixture that is 60 % salt, that means;A + B = 40
B = 40 - A ------------ [Equation 1]
Second condition states that Solution A is 40% salt and Solution B is 65% salt, that means;[tex]0.4 \text{A}+0.65 \text{B}=0.60 \times 40[/tex]
[tex]0.4 \text{A}+0.65 \text{B}=24[/tex]
[tex]0.4 \text{A}+0.65 (40- \text{A})=24[/tex] {from equation 1}
[tex]0.4 \text{A}+26- \text{0.65A}=24[/tex]
[tex]\text{0.65A} - 0.4 \text{A}=26-24[/tex]
[tex]\text{0.25A} =2[/tex]
A = [tex]\frac{2}{0.25}[/tex] = 8 ounces
Now, putting value of A in equation 1, we get;
B = 40 - A
B = 40 - 8 = 32 ounces
Hence, we need 8 ounces of solution A and 32 ounces of solution B.

Lyana is painting her bedroom. Her room is 12’ x 18’. The ceilings are 8 feet high. She will need to put two coats of paint on. How many cans of paint will she need if the square footage of one can is 400 square feet?
Answers
Answer:
2 cans to cover the room but she will have a lot of paint left over
Step-by-step explanation:
12*18=216
the area of her room is 216 square ft.
216*2=432
she will need 2 cans
Answer:
Lyana will need 4 cans of paint to paint her whole room or only 3 if she doesn't paint the floor.
Step-by-step explanation:
Firstly we need to know how much paint she will need to use.
The area of her room is given by 2(ac+bc), where a is the length, b is the width and c is the height.
Applying that we get that the area of her room is 2*12*18+2*18*8=720.
This applies if we assume that she also paints the floor. If she doesn't we need to subtract the area of the floor which is 12*18=216. So 720-216=504
She will paint her room twice she the amount of paint she needs is twice the area:
720*2=1440
or if she does not paint the floor
504*2=1008
Now we answer how many cans is that by dividing by 400 and rounding up.
1440/400=3.6 she needs, therefore, 4 cans
1008/400=2.52 she needs 3 cans

I believe its $66.04. If it asked for the total, then it would have been 66.04 + 508, which it did not ask. So try $66.04.
Step-by-step explanation:
508 is the actual price and 13% of 508 is 66.04.
Answer:
$66.04
Step-by-step explanation:
This is an example of a percentage of an amount.
The formula for the percentage of an amount is : [tex]\frac{Percentage}{100} *amount[/tex]
To work this out you would first need to convert the percentage of 13% into a decimal. You can do this by dividing the percentage of 13 by 100, this gives you 0.13. This is because percentages are out of 100.
To work out the price of shipping and handling you would need to multiply the amount of $508 by the decimal of 0.13, this gives you $66.04. This is because we are working out 13% of $508.
1) Divide 13 by 100.
[tex]13/100=0.13[/tex]
2) Multiply 0.13 by 508.
[tex]0.13*508=66.04[/tex]
Eight friends decided to try white-water rafting on a nearby river. They rented four two-person rafts; one was yellow, one was green, one was red, and one was blue. They selected partners for the four rafts and agreed on a destination at the end of a white-water run.
1. Phil and Cook, who were in the same raft, arrived at the destination without incident, but they were not the ones who finished first. 2. The red raft capsized and did not finish; the green raft was first to finish the white-water run. 3. O’Brien and LeRoy were not on the same raft. 4. Paul and Wilson finished last on their raft. 5. Fortunately, Henry is a good swimmer, and he helped his partner, Hughes (whose first name is not Walt), get to shore. They were able to recover their capsized raft, but declined to finish the white-water run. 6. Frank was the first to select a raft, and he picked the yellow one. He and Hawley were on the second raft to finish the white-water run. 7. Alan and Hughes were on the same raft; they were the first to finish the whitewater run. 8. LeRoy and Smith completed the run and were not in last place. 9. After their nearly tragic capsizing experience, Don and his partner, Gladstone, vowed not to set foot in another raft. 10. Alan did not care that he and his partner finished last; he was just glad they made it.
(a) Based on the following statements, one of which is false, what is the first name (Alan, Don, Frank, Henry, LeRoy, Paul, Phil, or Walt) and surname (Cook, Gladstone, Hawley, Huges, O’Brien, Sands, Smith, or Wilson) of each of the friends? (b) Which were partners on the four rafts? (c) What color raft was used by each?
Answers
Answer:
Leroy Sands & Walt Smith - greenFrank Cook & Phil Hawley - yellowPaul O'Brien & Alan Wilson - blueHenry Gladstone & Don Hughes - redStep-by-step explanation:
First of all, it is convenient to choose the false statement.
We note that statements 7 (Alan is first) and 10 (Alan did not finish) are contradictory, so one of them must be false. Statement 5 has Henry & Hughes together, so is not consistent with statement 7 (Alan & Hughes). So, statement 7 is inconsistent with two other statements, thus must be the false one.
__
The attached table shows how we parsed the statements. An "O" signifies a combination that must occur; and "X" signifies one that cannot occur. We have used "-" to fill the spaces that are inconsistent with the locations of "O". The red letters are deduced from the others.
The first complete set we found was Henry & Hughes (Don & Gladstone) who were in the (red) capsized raft and did not finish. The second complete set we found was Phil & Cook (Frank & Hawley) who were in the (yellow) raft that finished second. We know Paul & Wilson (Alan & Partner) finished last, so Phil & Cook could not have been Paul and Wilson. Finally, O'Brien and Leroy were not on the same boat, so Paul must be Paul O'Brien and Leroy must be Leroy Sands.

What is the value of x?
°x=32
°x=36
°x=37
°x=40
Answers
Answer: x= 40
Step-by-step explanation:
x + 4x -20=180
5x -20=180
+20 +20
5x= 200
x= 40
Answer:
A) x=32
Step-by-step explanation:
To work out the value of x you would first need to minus 20° from 180°, this gives you 160°. This is because the total angle in a straight line is 180° and that by subtracting 20 from 180 you are isolating the value of the x's.
The next step is to add up the number of x's in that angle. You can do this by adding the values of 4 and 1, this gives you 5.
The final step is to divide the angle 160 by the total number of x's of 5, this gives you 32°. This si because we had previously isolated the value of the 5x and so by dividing it by 5 so we would work out the value of x.
1) Minus 20 from 180.
[tex]180-20=160[/tex]
2) Add 4 and 1.
[tex]4+1=5[/tex]
3) Divide 160 by 5.
[tex]160/5=32[/tex]
23. The chair lift at a ski resort rises at an angle of 21° and attains a vertical
height of 1575 feet. How far does the chair lift travel up the side of a
mountain?
Answers
Answer:
The chair travels approximately 4,394.924 feet.
Step-by-step explanation:
We need to use trigonometric functions to solve this problem. You are given the opposite side of an angle and asked to find the hypotenuse. This means you must use sine, because sine is the ratio between opposite and hypotenuse.
Set up the equation as so:
sin(21) = 1575/x
(x being the hypotenuse). Solve for x by multiplying both sides by x and then dividing both sides by sin(21). Solve 1575/(sin(21)), and you get 4,394.924273, or 4,394.92

Step-by-step explanation:
2. The segment BD should be equal to 14, as then problem would be impossible. Then,
BD=14
BC=10 (given)
CD=14-BC=14-10=4
3. Angle CBD is equal to angle DBA, because BD bisects the angle CBA.
So, if we substitute the measures of the angles,
55 =x+12
55-12=x
x=43 degrees
4. Angle QRT+angle TRS=180 degrees because they are both on a straight line, which equals 180 degrees.
So, if we substitute with the measures of the angles,

Answers
Answer:
1209.06 cubic feet
Step-by-step explanation:
use the formula for the volume of a cylinder and the volume of a rectangular prism, and then plug the values into that
The volume of the composite figure consisting of a cylinder and a rectangular prisms to the nearest tenth is 1209.1ft³.
What is a cylinder and a rectangular prism?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.1415 )
A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles.
The volume of a rectangular prism is expressed as;
V = w × h × l
Where w is width, l is length and h is the height
From the diagram, the figure consist of a cylinder and a rectangular prism.
For the cylinder;
Radius r = 4ftHeight h = 4ftVolume of the cylinder V_c = ?For the rectangular prism;
Width w = 14ftLength l = 12ftHeight h = 6ftVolume of the rectangular prism V_r = ?Volume of the cylinder.
V_c = π × r² × h
V_c = 3.1415 × (4ft)² × 4ft
V_c = 3.1415 × 16ft² × 4ft
V_c = 201.1ft³
Volume of the rectangular prism.
V_r = w × h × l
V_r = 14ft × 6ft × 12ft
V_r = 1008ft³
Now, the volume of the composite figure will be;
V = V_c + V_r
V = 201.1ft³ + 1008ft³
V = 1209.1ft³
Therefore, the volume of the composite figure consisting of a cylinder and a rectangular prisms to the nearest tenth is 1209.1ft³.
