Answer:

Option (2)

Step-by-step explanation:

Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.

From the figure attached,

m∠C = [tex]\frac{1}{2}[m(\text{major arc AB})-m(\text{minor arc AB)}][/tex]

        = [tex]\frac{1}{2}[(360-m\widehat{AB})-m(\widehat{AB})][/tex]

        = [tex]\frac{1}{2}[360-2m(\widehat{AB})][/tex]

        = [tex]180-m\widehat{AB}[/tex]

        = 180 - 150

        = 30°

Therefore, measure of angle C will be 30°.

Option (2) is the answer.

Answer:

The polygon with the smallest perimeter is the megagon

The polygon with the largest perimeter is the triangle

Step-by-step explanation:

An equilateral triangle with area = 20 has

0.5× a²×sin60 = 20

a= 6.796

Hence, perimeter = 20.39

A square of area 20 has perimeter= 4×√20 = 17.9

A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05

Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases

Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.

Answer:

The value of a is -1.

Step-by-step explanation:

First, you have to add 3 to both sides :

[tex]2a - 3 + 3 = - 5 + 3[/tex]

[tex]2a = - 2[/tex]

Next, you have to divide both sides by 2 :

[tex]2a \div 2 = - 2 \div 2[/tex]

[tex]a = - 1[/tex]

Answer:

Option B, C and E are supplementary angles.

Step-by-step explanation:

We need to find supplementary angles.

Supplementary angles are those angles who sum up to 180 °.

I have attached picture for reference.

Looking at the figure given:

We have supplementary angles:

∠4 and ∠3

∠4 and ∠5

∠5 and ∠6

∠7 and ∠8

∠3 and ∠6

But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6

So, Option B, C and E are supplementary angles.

Supplementary angles are pair of adjacent angles that add up to 180 degrees

For a pair of angles to be supplementary, then the following must be true

Step-by-step explanation:

Answer: [tex]\dfrac{1}{8}[/tex]

Step-by-step explanation:

Formula : Probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

Given , Sam has 4 cards numbered 2,3,5, and 7.

His friend has 4 cards numbered 1,2,6 and 7.

If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).

i.e. Number of possible outcomes would be (S) 4 x 4 = 16

Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)

Now , the probability that they will both choose the same number would be :

[tex]\dfrac{F}{S}=\dfrac{2}{16}=\dfrac{1}{8}[/tex]

Hence, the required probability = [tex]\dfrac{1}{8}[/tex]

Height = 8cm

Step-by-step explanation:

I hope it helps

The required height of the cylinder is 8cm.

A  cylinder of base radius 4cm. The ratio of the area of it's base to that of it's curved surface area is 1:4. Height of cylinder is to be determine.

Surface area is defined as the area of the surface that are uncovered.

Here,
area of circle/surface area of cylinder=1/4
πr²/2πrh=1/4
r/2h=1/4
h=2r
where r = 4cm
h = 2*4
h = 8cm

Thus, the required height of the cylinder is 8cm.

Answer:

6, 9, 12

Step-by-step explanation:

Let s be the shortest side. Using the information you're given, you can create an equation. 27= s + s+3 + 2s. Now just solve the equation. Subtract 3 from both sides. 24=4s. Divide by 4 on both sides. 6=s. So the shortest side is 6 feet long, so we add 3 to that for the one that is neither the shortest or the longest. That side is 9 feet long. We double s to get 12, which is the longest side.

Answer:

Long side: 12

Middle side: 9

Shortest side: 6

Answer:

Total probability (first tile less than 7, second tile multiple of 4) = 2/21

Step-by-step explanation:

The question is not complete as the number of tile are not given. Howover, I could find the complete question on internet so I would solve for that. I hope it helps. (SEE THE ATTACHMENT)

You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. THE PROBABILITY OF CHOOSING A NUMBER LESS THAN 7 AND THEN A MULTIPLE OF 4 IS?

As we can see in the picture that there are a total of 7 tiles, so n = 7

These tiles are numbered as 5, 6, 7, 8, 9, 10, 20

Tiles having a number less than 7 = 5, 6

No. of tiles having a number less than 7 = 2

So probability of choosing a number less than 7 is = 2/7

After picking one tile and without replacing it, total no. tiles become n = 6

Tile having multiples of 4 = 8, 20

No. of tiles having multiples of 4 = 2

Probability of choosing a second tile with multiple of 4 = 2/6

Total probability (first tile less than 7, second tile multiple of 4) = (2/7) · (2/6) = 4/42 = 2/21

Answer:

-9.88.

Step-by-step explanation:

1. Write it out.

4.25-x=14.13

2. Make it a bit easier to read.

4.25-x=14.13 is also the same thing as... -x+4.25=14.13. Now it's easier to tell that 4.25 is positive.

3. Isolate x and get it by itself.

Since we have a number on x's side, we have to move it to the other side. The opposite of addition is subtraction, so we subtract 4.25 by both sides!

-x+4.25=14.13

  -4.25  -4.25

-x=9.88

Technically, x can't really be negative, so we can just divide by negative one on each side to get rid of the negative x.

-x=9.88

/-1   /-1

x=-9.88

#SPJ2

Answer:

z = 3

Step-by-step explanation:

Using the rule of exponents

[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]

Thus

[tex](q^{4}) ^{z}[/tex] = [tex]q^{4z}[/tex] , so

[tex]q^{4z}[/tex] = [tex]q^{12}[/tex]

Since the bases on both sides are equal then equate the exponents

4z = 12 ( divide both sides by 4 )

z = 3

Answer:

The value of z is 3.

Step-by-step explanation:

You have to use Indices Law,

[tex] {( {a}^{m}) }^{n} \: ⇒ \: {a}^{mn} [/tex]

So for this question, first you have to get rid of brackets :

[tex] { ({q}^{4} )}^{z} = {q}^{12} [/tex]

[tex] {q}^{4z} = {q}^{12} [/tex]

Next you can solve it since both have the same bases :

[tex] {q}^{4z} = {q}^{12} [/tex]

[tex]4z = 12[/tex]

[tex]z = 3[/tex]
