<h3>Answer:  1/36</h3>

===========================================================

Explanation:

The only prime number of the list of values given is the value 13. This is because the only factors are 1 and 13. Something like 24 isn't prime because 2 is a factor.

The probability of rolling to get a prime number is 1/6 because there is one prime out of 6 total values listed.

The probability of spinning on "G" is also 1/6 because there is only one section labeled "G" out of 6 sections total.

Assuming both events are independent, we multiply the probabilities to get (1/6)*(1/6) = 1/36 which represents the probability of rolling a prime number and spinning on G.

Side note: 1/36 = 0.0278 = 2.78% approximately

Two lines intersect at a point. The vertical angles formed are supplementary.
Nastasia [14]

we know that

<u>Vertical angles</u> are a pair of opposite and congruent angles formed by intersecting lines.

so

Let

x1---------> angle vertical 1

x2---------> angle vertical 2

x1=x2 ------> equation 1

in this problem

if the vertical angles formed are supplementary

that means that

x1+x2=180 ------> equation 2

substitute equation 1 in equation 2

x1+x1=180

2x1=180

x1=180/2

x1=90 degrees

therefore

<u>the answer is</u>

The vertical angles are right angles

Find the missing side or angle. Round to the nearest tenth. C=53° B= 80° a=2 b=[ ? ]​
Degger [83]

9514 1404 393

Answer:

  b ≈ 2.7

Step-by-step explanation:

The missing angle A is ...

  A = 180° -53° -80° = 47°

The law of sines tells you ...

  b/sin(B) = a/sin(A)

  b = sin(80°)×2/sin(47°) ≈ 2.6931

Side b is about 2.7 units.

Please help! 9/4(7+3-4*9)
Serga [27]

Answer:

58.5

Step-by-step explanation:

This expression should be simplified using order of operations. According to order of operations or PEMDAS, complete any numbers in parenthesis then any exponents, multiplication, division, additions and subtraction moving left to right through each operation.

Begin with Parenthesis.

(7+3-4*9) - Multiply first

(7+3-36) - Then add/subtract left to right

10 - 36 = -26

Replace -26 where the parenthesis were in the original expression.

9/4 (-26)

234/4
