If you roll two fair six-sided dice, what is the probability that both dice show an odd number?

Answers

Answer 1

Answer:

1/4

Step-by-step explanation:

Both dice have odd numbers 1, 3, 5. The chances of getting an odd number on each number is 3/6

The probability of getting odd numbers on both is:

3/6 ⋅ 3/6 = 9/36 = 1/4

Answer:

Yes The triangles are similar by SAS Similarity Theorem

Step-by-step explanation:

we know that

Side-Angle-Side Similarity, states that If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar

In this problem

Angle  L is congruent with Angle Z

so

Verify if the included sides are proportional

so

Which graph shows a graph of a circle with equation x 2 + (y+3) 2 =9

Answers

Answer:

The graph of the circle is given in the image attached

Final answer:

To graph the circle represented by the equation x^2 + (y+3)^2 = 9, identify the center at (0,-3) and radius 3, then plot the center and draw the circle on a graph.

Explanation:

The student's question relates to the equation of a circle in Cartesian coordinates and how to graph it. Given the equation x2 + (y+3)2 = 9, we can determine the center and the radius of the circle it represents. To graph the circle, first identify the center, which in this case is at (0, -3), because the equation can be written in the standard form (x - h)2 + (y - k)2 = r2 where (h, k) is the center and r is the radius. Then find the radius by taking the square root of the right side of the equation, which is 3 in this case.

Plot the center on the Cartesian graph, and draw a circle around it with a radius of 3 units, ensuring that possible points on the circle follow the equation such as (0,0), (-3,-3), and (3,-3) for instance.

What is the measure of ∠MNO?

Answers

Answer:

∠MNO = 51°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x + 15 + 2x + 25 + 5x + 10 = 180 ← simplify left side

10x + 50 = 180 ( subtract 50 from both sides )

10x = 130 ( divide both sides by 10 )

x = 13

∠MNO = 2x + 25 = (2 × 13) + 25 = 26 + 25 = 51°

simplify the expression 7√5-3√80​

Answers

Final answer:

To simplify the expression 7√5-3√80, the second term is broken down and then subtracted from the first term, resulting in the final simplified answer of √5.

Explanation:

To simplify the expression 7√5-3√80, we should first break down the second term, 3√80, into simpler terms.

The second term can be rewritten as 3√(4*20), since 4*20 = 80. Then this can be further broken down into 3√(4*4*5) which equals 3*2√5. In other words, 3√80 equals 6√5.

So, the original expression, 7√5-3√80, can now be rewritten as 7√5 - 6√5.

Since these two terms share the same radical, √5, you can subtract them just like you would subtract regular numbers. So, 7√5 - 6√5 equals 1√5, which simplifies further to √5.

#SPJ12

Final answer:

To simplify the given expression, we simplify the square roots and combine like terms. The expression simplifies to -5√5.

Explanation:

To simplify the expression 7√5-3√80, we need to simplify the square roots.

The square root of 5 cannot be simplified further, but the square root of 80 can be simplified as the square root of 16 times the square root of 5.

Therefore, the expression becomes 7√5 - 3√16√5.

The square root of 16 is 4, so the expression simplifies to 7√5 - 3(4)√5. Continuing to simplify, we get 7√5 - 12√5.

Combining the like terms, we have (7-12)√5, which simplifies to -5√5.

Answers

The height of the rocket increases for some time and then decreases for some time.

The height from the ground increases from 4 to 26, then decreases from 26 to 0.

Why the others are wrong.

A. The height of the rocket changes at a constant rate for the entire time.

The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.

C. The height of the rocket remains constant for some time.

The graph is a curve. This means the rate is not constant. If it were constant, the graph would be linear - a straight line.

D. The height of the rocket decreases for some time and then increases for some time.

This implies the graph decreases first then increases. However, the rocket will increase, then decrease.

Find the volume of the rectangular prism

Answers

Answer:

V = 490 cm^3

Step-by-step explanation:

V = l*w*h

V = 7*10*7

V = 490 cm^3

To find the volume of a rectangular prism, we use the formula

Volume = length × width × height.

Since the rectangular prism has a length of 10 cm, a width of 7 cm, and a height of 7 cm we can plug this information into the formula.

(10 cm) (7 cm) (7 cm)

10 × 7 = 70

70 × 7 = 490 cm³

The choir sold boxes of candy and teddy bears near Valentine’s Day to raise money. They sold 57 items altogether. Bears sold for $8.00 each and each box of candy sold for $6.00. They collected $380. How much of each item did they sell

Answers

Answer:

19 bears, 38 boxes of candy.

Step-by-step explanation:

We can use a system of equations (b = # of bears, c = # of candy boxes):

b + c = 57, 8b + 6c = 380.

We can use substitution by isolating b in the first eq.: b = 57 - c, then substitution b with 57 - c in the second eq.: 8(57 - c) + 6c = 380.

Then, we solve: 456 - 8c + 6c = 380, 76 = 2c, c = 38 candy boxes.

Finally we plug in 38 for c in the first eq.: b + 38 = 57, b = 19 bears.

Step-by-step explanation:

Given in the question,

radius = 3x

tangents to the circle = 12 + 5x and 8 + 7x

If you draw line from A to D, two right angle triangle will be form ADC and ADB

having radius  = 3x

By using pythagorus theoremhypotenuse² = base² + height²

Since, both triangle share same hypotenuse AD

so,

    ΔADC                        ΔADBbase² + height² = base² + height²

3x² + (8 + 7x)² = 3x²  + (12 + 5x)²

3x² will be cancel out

(8 + 7x)² =  (12 + 5x)²

64 + 112x + 49x² = 144 + 120x + 25x²

rearranging like terms

49x²-25x² +112x - 120x + 64 -144 = 0

24x² - 8x - 80 = 0

(x- 2)(x + 5/3)

x = 2

x = -5/3 rejected as radius can't be negative

So,

length of radius = 3x = 6

The trig function relating this 30° angle, the 2√3 hypotenuse and the adj. side labeled 'y' is the cosine:

                 adjacent side          y

cos 30° = ---------------------- = --------- , and the value of cos 30° is (√3)/2.
