∠A and ∠B are complementary, and ∠B and ∠C are supplementary.
If the m∠A is 29°, what are the m∠B and m∠C?)

A. m∠B= 119°, m∠C = 151°
B. m∠B= 61°, m∠C = 151°
C. m∠B= 119°, m∠C = 61°
D. m∠B= 61°, m∠C = 119°

Answers

Answer 1

Step-by-step explanation:

m∠A = 29°

∠A and ∠B are complementary, then

m∠A + m∠B = 90°

29° + m∠B = 90°

m∠B = 90° - 29°

= 61°

∠B and ∠C are supplementary, then

m∠B + m∠C = 180°

61° + m∠C = 180°

m∠C = 180° - 61

= 119°

therefore the answer is D. m∠B = 61°, m∠C = 119°

Find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards.

Answers

Answer:

A deck of cards contains RED cards numbered 1,2 and BLUE cards numbered ... Patricia will draw 8 cards from a standard 52-card deck with replacement. ... Outcome: any of the possible results of an experiment in probability. ... Correct answers:$\frac{7}{9}$7/9​​ ... Event A: rolling a 6-sided fair number cube and getting 1Step-by-step explanation:

The probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.

To find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards, we need to calculate the probabilities of each event and then multiply them together since the events are independent (the outcome of one event does not affect the outcome of the other event).

1. Probability of rolling an odd number on a fair number cube:

A fair number cube has 6 faces with numbers 1 through 6. Out of these, three numbers are odd: 1, 3, and 5. So, the probability of rolling an odd number is 3/6, which simplifies to 1/2.

2. Probability of drawing a 7 of any suit from a standard deck of cards:

A standard deck of cards has 52 cards. There are four 7s in the deck (one for each suit: hearts, diamonds, clubs, and spades). So, the probability of drawing a 7 is 4/52, which simplifies to 1/13.

Now, multiply the probabilities together:

Probability = (Probability of rolling an odd number) * (Probability of drawing a 7)

Probability = (1/2) * (1/13)

Probability = 1/26

Therefore, the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.

What is the solution to this system?

Answers

Answer: There is no solution

Step-by-step explanation:

The system of a systems of equations on a graph is the coordinate where the 2 lines intersect, or come together. In this picture, the 2 lines don't intersect at a point, so there is no solution. Here are some rules for systems of equations on a graph:

How to know if it has 'infinite' solutions: If it has infinite solutions, the 2 lines share the same points. In other words, they are basically just on top of each other, or in the exact same spot.

How to know if there are 'no solutions': The 2 lines never come together (intersect). This is true in this graph because they are always apart.

How to know if there is 'one solutioin': The 2 lines cross each other, come together, or intersect (all the same meaning), at 1 point .

find the volume of the cone using the given formula

Answers

Answer:

I believe your answer would be

Step-by-step explanation:

Using that formula, we can substitute in the values we need that are given to us in the question:

h = 12

r = 4

Now we need to use the formula.

V = 1/3 (pi) (4²) (12)

First lets do the exponent.

4² = 16

V = 1/3 (pi) (16) (12)

Now lets do pi × 16.

pi × 16 = 50.2654824574.

Now we have:

V = 1/3 (50.2654824574) (12)

Multiply 50.2654824574 and 12.

50.2654824574 × 12 = 603.185789489

Now all we have:

V = 1/3 (603.185789489)

Multiply them.

V = 201.06192983

So, your answer is V ≈ 201.06192983, or 201.
