Step-by-step explanation:

The supplement of 50° is the angle that when added to 50° forms a straight angle (180° ).

Answer:

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

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

First do inside the parentheses:

4 + [8/1 + 6-12] . 10

Now work inside the brackets doing division first

4 + [8 + 6 -12]. 10

Still inside the brackets add an subtract from left to right:

4 + 2 . 10

Multiply:

4 + 20

Add to get final answer of 24

Answer:

4+[8 ÷(8-7) +6 -12] . 10

4+[8÷1+6-12].10

4+[8+6-12].10

4+[14-12].10

Step-by-step explanation:

To solve think about how many sections there truly are. The 5 section represents 3 parts, the 2 section represents 2 parts, and the 1, 4, 3 sections represent 3 parts in total. This means overall there are 8 parts to this spinner. Since 5 takes up 3 of these 8 parts, the probability of the pointer landing on 5 is 3/8.

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.

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.

Commutative Property of Multiplication

The value of the given expression is 5^(3/4).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression can be resolved as shown below,

5² ÷ √5

[tex]= \dfrac{5^2}{\sqrt5}\\\\\\[/tex]

Using the law of exponents, [tex]\sqrt[n]{m} = m^{\frac1n}[/tex],

[tex]= \dfrac{5^2}{5^{\frac12}}\\\\\\[/tex]

Using the law of exponents, [tex]m^x\times m^y = m^{x+y}[/tex],

[tex]= {5^2} \times {5^{-\frac12}}[/tex]

Answer:

4) 8

Step-by-step explanation:

In the formula y = mx + b, m is the slope and b is the y-intercept

m = 8

b = -1

If m = 8 and m is the slope, then the slope is 8

Answer:

Step-by-step explanation:

m1+m2=180

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°

Solution:

Given ratio - 3:5

1 part = 3

2 part = 5

Total no. of parts = 3 + 5 = 8 parts

400 / 8 = 50

3 * 50 = 150

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.

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]
