Answers
Answer:
z = 3
Step-by-step explanation:
Similar polygons have the ratio of their corresponding sides equal to each other. There:
9/z = 6/2
Cross multiply
z*6 = 9*2
6z = 18
z = 18/6
z = 3

UT = TW + WU = 27 + 27 = 54
WT = 27
ST = UT = 54

arc(US) = arc(ST) + arc(UT) = 104 + 104 = 208
I know it was super drawn out and there were probably quicker ways to do it, but I was justusing methods that came to mind rather than going for efficiency. let me know if any part is confusing.
Step-by-step explanation:
Let's start by just building on what we know
Since we know sv and vz can be made into the side of two triangles, SZV and TZV, we can use some similar triangle rules.
In SZV and TZV we know SZ = TZ since they are both radii, ZV = ZV because they are the same line and angle ZVS = angle ZVT since they are supplementary and one is 90 degrees. This allows us to solve and see if they are congruent or not. To do so we use the normal trig functions
sin(ZTV) = ZV/ZT = ZV/12
sin(ZSV) = ZV/SV = ZV/12
So the angles could be equal, but just to be sure lets look at all possible answers. with sine an angle x gives the same result as 180-x. Since both angles are acute thugh we know this can't be true so both angles are equal. Now we can say both triangles are congruent by AAS. Since they are congruent we can then confirm SV = VT.
In general you can say if a radii intersects a chord at a right angle then the intersection is a bisection. So now we know VT = 27
We can use similar methods to show UW = WT and if you made two triangles ZWT and ZWU you will see they are congruent. and since arc UT is 104 degrees that means angle UZT is 104 degrees. Since ZW bisects UT and the two triangles are congruent ZW also bisects angle UZT so UZW = TZW = 52 degrees.
Now we have 4 triangles, SZV, TZV, ZWT and ZWU and we know SZV and TZV are congruent and ZWT and ZWU are congruent. Now, if we can make one from each pair congruent we would knwo all four are congruent. Since TZV and ZWT share a side that's a good place to start. Looking at these two triangles we know those two sides are equal, and they both have a right angle. Also we know VZ = ZW fromt he instructions, so this is again a chance to check with trig.
Let's look at angle ZTW and ZTV.
sin(ZTW) = ZW/ZT = 27/ZT
sin(ZTV) = VZ/ZT = 27/ZT
Using the same reasoning as before we can say that the two angles are equal, so the two triangles are congruent. Now we can say a lot.
angle UZT = angle SZT = 104 degrees
angle SZV = angle VZT = angle TZW = angle WZU = 52
SV = VT = TW = WU = 27
Let's start solving.
UT = TW + WU = 27 + 27 = 54
WT = 27
ST = UT = 54
arc(XT) = angle XZT = 52 degrees
arc(ST) = angle SZT = 104
arc(US) = arc(ST) + arc(UT) = 104 + 104 = 208

A helicopter and a plane can make a safe landing if at least half of its engines are working properly. Suppose that engine failures are independent events. Determine whether a two engine helicopter or a four engine plane is safer if the chance that an engine fails is 1 in 100?
Answers
Answer:
I'm going to make an uneducated guess here.
I think the probability of two engines failing would be the same for either aircraft. In the instance that does happen, the helicopter doesn't fly at all and the airplane does.
I say the airplane is safer.
Step-by-step explanation:
So, the plane is safer than the helicopter.
Binomial distribution:
The formula for finding the probability by Binomial distribution is,
[tex]P(X = x) = n_C_x \times p^x \times (1 - p)^{(n - x)}[/tex]
For Helicopter,
We need to calculate, Probability of safe landing, [tex]P(X = 0)[/tex]
Here, [tex]n = 2, p = 0.99, (1 - p) = 0.01\ and\ x = 1[/tex]
As per binomial distribution formula [tex]P(X = x) = n_C_x \times p^x \times (1 - p)^{(n - x)}[/tex]
We need to calculate [tex]P(X \ge 1).[/tex]
[tex]P(X \ge1) = (2_C_1 \times 0.99^1 \times 0.01^1) + (2_C_2 \times 0.99^2 \times 0.01^0)\\P(X \ge1) = 0.0198 + 0.9801\\P(X \ge 1) = 0.9999[/tex]
For Plane,[tex]P(safe\ landing)[/tex]
Here, [tex]n = 4, p = 0.99, (1 - p) = 0.01\ and\ x = 2[/tex]
As per binomial distribution formula [tex]P(X = x) = n_C_x \times p^x \times (1 - p)^{(n - x)}[/tex]
We need to calculate P(X >= 2).
[tex]P(X \ge 2) = (4_C_2 \times 0.99^2 \times 0.01^2) + (4_C_3 \times 0.99^3 \times 0.01^1) + (4_C_4 \times 0.99^4 \times 0.01^0)\\P(X \ge 2) = 0.0006 + 0.0388 + 0.9606\\P(X \ge2) = 1\\[/tex]

what is the area of this cross section of this rectangular prism?
Answers
Answer:
Step-by-step explanation
cross-section is 10 inches by 16 inches
area = 10*16 = 160 square inches
The area of the shown cross-section is 160 square inches.
What is the area of the cross-section?
As you can see in the image, the cross-section of a rectangular prism is actually a rectangle.
Here, the dimensions of the rectangular cross-section is:
L = 16 in
H = 10 in
The area will be the product of these two values, so we will get:
A = L*H = (16 in)*(10 in) = 160 in^2
So the area of the shown cross-section is 160 square inches.

A cube-shaped box can be wrapped completely in gift wrap that measures 384 square inches. What is the volume of the box?
Answers
Answer:

Step-by-step explanation:
√384=19.6
19.6, is therefore the length of one side
Volume of cube is length³
19.6³=7529.536
Well it's just a try for me
The volume of the box when there is the cube shaped box wrapped and it should measured 384 square inches so it is 7529.536.
Calculation of the volume of the box;Since
A cube-shaped box can be wrapped completely in gift wrap that measures 384 square inches
So here the side should be like
[tex]= \sqrt{384}[/tex]
= 19.6
Now the volume of the box should be

3x+x+44=180
4x+44=180
4x=136
x=34
m1=3x=3(34)
m1=102 degrees
m2=x+44=34+44
m2=78 degrees
Answer:
The two angles added together are equal to 180 degrees because they lie on a straight line and a straight line is always equal to 180 degrees.
∠1 + ∠2 = 180°
∠1 = 3x, ∠2 = x + 44
Substitute the values of ∠1 and ∠2
3x + x + 44 = 180
4x + 44 = 180
4x = 136
x = 34
If x = 34,
∠1 = 3 * 34 = 102°
∠2 = 34 + 44 = 78°
