I Need Help Asap Please!!! "Find The Measure Of Arc AC In The Figure Below. Explain Your Answer By Showing

Answers

Answer 1

The angle measure of arc AC at the center of the circle is; 21°

Circle theorems

From the task content;

The angle subtended by the arc at the center of the circle is; (3x +9)°

The angle subtended by the arc on the circumference of the circle is; (3x -1.5)°

It follows that from circle theorems that; The angle subtended by an arc at the center of a circle is twice that which it subtends at the circumference.

Hence;

(3x +9)° = 2(3x -1.5)°

3x +9 = 6x -3

3x = 12

x = 4.

By substituting x= 4 into the expression; (3x +9)°

Hence, the angle subtended at the center of the circle is; 12+9 = 21°.

solve for p..........​

Answers

Answer:

the answer is p = 15

Step-by-step explanation:

first you set the equation to 2p + 9 = 3p - 6

then solve out the equation by adding 6 to both sides

the equation will now look like this, 2p + 15 = 3p

now you subtract 2p from both sides

the equation now looks like 15 = p

I always flip my equations so I can read it better,

p = 15

Of the 44 players attributed to a playwright 11 are comedies 17 are tragedies and 16 are histories if one play is selected at random find the odds against selecting a tragedy

Answers

Step-by-step explanation:

since the total number of players is 44, the Universal set will also be 44.

let C be the set for Comedy

let T be the set for Tragedy

let H be the set for Histories

ξ = { 44 }

C = { 11 }

T = { 17 }

H = { 16 }

probability T = (17/44)

odds of selecting T = probability not T

= 1 - probability T

= 1 - ( 17/44)

= 27/44

you need to give the answer as a ratio of odds of selecting T against chances of selecting T;

if out of 44 players, the chances of not selecting T is 27 and the chances of selecting T is 17, then:

odds against selecting random is, 27: 17

that's the answer. hope this helps you!

Answer:

First you need to make 3 1/2 into a improper fraction so you multiply 3 x 2 and then add 1 which is 7/2. Next you need to divide it by 5/8. So to divide fraction you have to do K.C.F. (Keep, change, flip). So you keep the 7/2 change the division symbol to a multiplication symbol. and then flip the 5/8 into 8/5. So the whole problem would be 7/2 x 8/5. next you just multiply.

7 x 8 = 56

2 x 5 = 10

next you just need to simplify into the smallest fraction and you can simplify both by 2. So 56 / 2 = 28 and 10 / 2 = 5. That's how the solution is 28/5.

Also, the value of the expression 5 x 8/5 is 25/8.

Answer:

make 3 1/2 into a improper fraction by multiplying the 3 and the 2 in the denominator together and then add 1 in the numerator to get 7 then make it 7/2 since the 2 was the denominator in the mixed fraction. Then keep the 7/2 the same turn the division symbol to a multiplication symbol then turn the 5/8 into 8/5 by flipping it then multiply. 7×8= 56 2×5=10 now you have 56/10 so you need to simplify. 2 is common between 56 and 10 so you multiply 56/10 and 2 together. 56÷2= 28 and 10÷2= 5 so now it is 28/5.

(Y)," which of the
following is the correct probability distribution?

Answers

Answer:

its A

Step-by-step explanation:

The solution is, the correct probability distribution is 1/16.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

Given that,  

spinner contains four sections: red, blue, green, and yellow. Joaquin spins the spinner twice. The set of outcomes is given as

S = {RB, RG, RY, RR, BR, BG, BY, BB, GR, GB, GY, GG, YR, YB, YG, YY}.

If the random variable is “yellow (Y),” let us first find the values that Y can take.

From the sample space given above, we find that Y can take only 3 values 0,1,2

In the sample space of 16 entries, Y occurs 0 times in 9 times

1 time in 6 times and 2 times 1 time

Hence probability = no of favouable outcomes/number in sample space

So

P(Y=0) = 9/16

P(Y=1) = 6/16 = 3/8

P(Y=2) = 1/16

Hence, The solution is, the correct probability distribution is 1/16.

Find the apothem of a regular 12-gon (12-sided polygon) if each side is 4.2 cm, and has
an area of 197 sq. cm.

Answers

Answer:

  7.8 cm

Step-by-step explanation:

The relevant formula is ...

  A = 1/2aP . . . . where a is the apothem, and P is the perimeter.

For a regular 12-gon the perimeter is 12 times the side length, so we have ...

  P = 12s = 12(4.2 cm) = 50.4 cm

Then the apothem is found from ...

  197 cm² = (1/2)a·(50.4 cm)

  a = 197/25.2 cm ≈ 7.81 cm

The apothem is about 7.8 cm.

__

Additional comment

A regular 12-gon with a side length of 4.2 cm will have an area of about 197.500 cm². The apothem will be about 7.837 cm. The area of a regular n-gon can be calculated from the side length as ...

  A = ns²/(4·tan(180°/n))

Similarly, the apothem will be ...

  a = s/(2·tan(180°/n))

let f(x)=|2x+10| and g(x)=|2x-24|. find all the values of x for which f(x)=g(x).

Answer:

8.5

Step-by-step explanation:

two cases:

1) 2x + 10 = 2x - 24, 10 = -24, impossible!

2) 2x + 10 = -(2x - 24)

2x + 10 = -2x - 24

4x = 34

x = 34/4 = 17/2 = 8.5

Two​ vehicles, a car and a​ truck, leave an intersection at the same time. The car heads east at an average speed of 30 miles per​ hour, while the truck heads south at an average speed of 40 miles per hour. Find an expression for their distance apart d​ (in miles) at the end of t hours.

Answers

Step-by-step explanation:

the car distance to the intersection will be

30t (30 miles for every hour).

the truck distance to the intersection will be

40t (40 miles for every hour).

the distance between the car and the truck will always be the Hypotenuse of a right-angled triangle with the legs being the actual distances from the starting intersection.

so, we use Pythagoras :

d² = (30t)² + (40t)² = 900t² + 1600t² = 2500t²

d = sqrt(2500t²) = 50t

so, their distance will increase 50 miles every hour.
