12 marbles are in a bag; 3 each of red, blue, green, and orange. If 3 marbles are chosen at random, what is the probability that all 3 are green?

Answers

Answer: [tex]\dfrac{1}{220}[/tex]

Step-by-step explanation:

Given

There are 3 marbles of red, blue, green and orange

Total marbles are 12

No of ways of choosing 3 green marbles out of 3 green marbles is [tex]^3C_3[/tex]

Total no of ways of selecting 3 marbles out of 12 are [tex]^{12}C_3[/tex]

So, the probability is

[tex]\Rightarrow P=\dfrac{^3C_3}{^{12}C_3}=\dfrac{1\times 3\times 2\times 1}{12\times 11\times 10}\\\\\Rightarrow P=\dfrac{1}{220}[/tex]

In △PQS, m∠Q=22°, m∠S=65°, and s=176. Identify q rounded to the nearest tenth.

Answers

So you would use law of sines to find q

So, sin(22)/q = sin(65)/176

(176sin(22)) / sin(65) = q

q = 72.7465

Rounded to the nearest tenth would be
72.7

So the last answer choice

Using the law of sines, the value of q is: D. 72.7.

What is the Law of Sines?

The law of sines is given as: sin A/a = sin B/b = sin C/c.

Thus, given △PQS, where:

m∠Q = 22°

m∠S = 65°

s = 176

Applying the law of sines, we have:

sin Q/q = sin S/s

Substitute

sin 22/q = sin 65/176

q = (sin 22 × 176)/sin 65

q = 72.7

Therefore, using the law of sines, the value of q is: D. 72.7.

1 3/4 cups of flour for one batch but he wants to make 1 1/2 batches. How many more cups of flour will he need

Answers

Answer:

[tex]2\frac{5}{8} cups = 1\frac{1}{2}\ batches[/tex]

Step-by-step explanation:

Given

[tex]1\frac{3}{4} cups = 1\ batch[/tex]

Required

Number of cups for [tex]1\frac{1}{2}[/tex] batches

[tex]1\frac{3}{4} cups = 1\ batch[/tex]

Multiply both sides by [tex]1\frac{1}{2}[/tex]

[tex]1\frac{1}{2} * 1\frac{3}{4} cups = 1\ batch * 1\frac{1}{2}[/tex]

[tex]1\frac{1}{2} * 1\frac{3}{4} cups = 1\frac{1}{2}\ batches[/tex]

Express fractions as improper fractions

[tex]\frac{3}{2} * \frac{7}{4} cups = 1\frac{1}{2}\ batches[/tex]

[tex]\frac{21}{8} cups = 1\frac{1}{2}\ batches[/tex]

Express fraction as improper fraction

Answer:

17

Step-by-step explanation:

From Pythagoras :

Hypotenus = sqrt(opposite² + adjacent²)

From the diagram

l = sqrt((l-9)² + 15²)

l² = (l² - 18x + 81 + 225)

Square both sides

l² = l² - 18x + 306

l² - l² = 306 - 18x

18l = 306

l = 306/18

l = 17

Describe the sequence of transformations that maps PQR into P'Q'R' use the drop-down menus to explain your answer

Answers

Answer:

Rotation of 180° clockwise around the origin

Step-by-step explanation: if you rotate the first triangle 90 degrees, it will be in the lower quarter, so you need to rotate it 1 more time.

The transformations are clockwise rotation 180° and translation down by 1 unit.

What is rotation?

Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.

From the given graph, the coordinates of triangle PQR are P(2, 1), Q(4, 6) and R(4, 1).

Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise direction, we have (-x,-y).

Here,

P(2, 1) → P'(-2, -1)

Q(4, 6) → Q'(-4, -6)

R(4, 1) → R'(-4, -1)

The translation down by 1 unit, we get (x, y-k)

P'(-2, -1) → P'(-2, -2)

Q'(-4, -6) → Q'(-4, -7)

R'(-4, -1) → R'(-4, -2)

The coordinates of triangle P'Q'R' are P'(-2, -2), Q(-4, -7) and R'(-4, -2)

Therefore, the transformations are clockwise rotation 180° and translation down by 1 unit.
