Answer:

\(6 \sqrt{8} \sqrt{2} = 6 \sqrt{16} = 6(4) = 24\)

B is the correct answer.

Option D is the correct answer.

Answer:

D. ∠B and ∠C are congruent.

Step-by-step explanation:

Since, ∠A and ∠B are supplementary.

Therefore,

∠A + ∠B = 180°.....(1)

Since, ∠A and ∠C are supplementary.

Therefore,

∠A + ∠C = 180°.....(2)

From equations (1) & (2)

∠A + ∠B = ∠A + ∠C

=> ∠B = ∠C

Hence, ∠B and ∠C are congruent.

Answer:

\(x=11\)

Answer:42

Step-by-step explanation:

we need to find the product of the number of options for each category.

Emily has:

7 shirts

2 pairs of pants

2 skirts (not mentioned if she can wear them with shirts, so we'll exclude them for now)

3 pairs of shoes

Since Emily wears one shirt, one pair of pants, and one pair of shoes each day, we can multiply the number of options for each category:

7 shirts * 2 pants * 3 shoes = 42 different outfits

Therefore, Emily can make 42 different outfits from the new clothes and shoes she bought.

Answer: y=2x+1

Step-by-step explanation:

To solve for y, we want to use our algebraic properties to isolate y.

16x+9=9y-2x               [add both sides by 2x]

18x+9=9y                     [divide both sides by 9, divide to each term]

2x+1=y

Now, we know that y=2x+1.

The total cost of materials can be found from a list of materials based on the market unit rate.

The correct responses are;

Reasons:

Part A: The given expression representing the purchase is presented as follows;

Purchases = 180·s + 9·p + 36·l

Where;

s = Screws

P = Posts

l = Lumber

The factored expression is found as follows;

Purchases = 180·s + 9·p + 36·l = 9 × 20·s + 9·p + 9 × 4·l, which gives;

180·s + 9·p + 36·l = 9 × (20·s + p + 4·l)

The factored expression is; 9 × (20·s + p + 4·l)

Part B: The costs are;

100 screws  = $6.99

1 posts = $16.40

10 pieces of lumber = $88.20

The materials Roberto need to buy are;

180 screws, which can be obtained by buying 2 cartons of screws.

9 posts, which is obtained by buying 9 pieces of posts.

36 lumber which can be obtained by buying 4 × 10 pieces = 40 pieces of lumber.

Therefore, the, material Roberto needs to buy are;

2 cartons of screws

9 pieces of posts

40 pieces of lumber

Part C: The total cost of the materials are therefore;

2 cartons of screws × $6.99 per carton = $13.98

9 pieces of posts × $16.40 per piece = $147.6

4 Sets of 10 pieces of lumber × $88.20 per set = $352.8

The total cost = $13.98 + $147.6 + $352.8 = $514.38

The equation of the perpendicular line is y = (-3/2)x + 2.

Option A is the correct answer.

We have,

From the graph,

The line has coordinates: (0, -1), and (-3, -3).

Now,

The equation of the line can be written as:

y = mx + c

m = (-3 +1) / (-3 - 0) = -2/-3 = 2/3

(0, -1) = (x, y)

-1 = 2/3 x 0 + c

c = -2

So,

y = (2/3)x - 2

Now,

Any line y = m(2)x + c perpendicular to y = (2/3)x -2 will have slope as:

m(2) x m = - 1

m(2) = - 1 / (2/3) = -3/2

Thus,

The equation of the perpendicular line is y = (-3/2)x + 2.

From the attachment, we have that

θ = 20°

Radius, r = 27

Required

Find length of AB

AB is an arc and it's length can be calculated using arc length formula.

\(Length = \frac{\theta}{360} * 2\pi r\)

Substitute 20 for θ and 27 for r

\(Length = \frac{20}{360} * 2\pi *27\)

\(Length = \frac{20 * 2\pi * 27}{360}\)

\(Length = \frac{1080 \pi}{360}\)

\(Length = 3\pi\)

The probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Since the probability density function is uniform, the probability of the friend being between 10 and 30 minutes late is equal to the area of the rectangle that lies between x = 10 and x = 30, and below the curve of the probability density function.

The height of the rectangle is equal to the maximum value of the probability density function, which is 1/30 since the interval of possible values for x is [0, 30] minutes.

The width of the rectangle is equal to the difference between the upper and lower limits of the interval, which is 30 - 10 = 20 minutes.

Therefore, the probability of the friend being between 10 and 30 minutes late is:

P(10 < x < 30) = (height of rectangle) x (width of rectangle)

= (1/30) x 20

= 2/3

≈ 0.6667

So the probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Here is your answer.

A tank contains 5832 litres of water.

Total amount of water in tank = 5832 litres.

Each day one-third of the water in the tank is removed and not replaced.

Since one third of the water is removed for six days.

1st day = 1/3rd of 5832 litres is removed

\( = \dfrac{5832}{3} = 1944\)

Amount of water left = 5832 - 1944 = 3888 litres

2nd day = 1/3rd of 3888 litres is removed

\( = \dfrac{3888}{3} = 1296 \)

Amount of water left = 3888 - 1296 = 2592 litres

3rd day = 1/3rd of 2592 litres is removed

\( = \dfrac{2592}{3} = 864 \)

Amount of water left = 2592 - 864 = 1728 litres

4th day = 1/3rd of 1728 litres is removed

\( = \dfrac{1728}{3} = 576 \)

Amount of water left = 1728 - 576 = 1152 litres

5th day = 1/3rrd of 1152 litres is removed

\( = \dfrac{1152}{3} =384 \)

Amount of water left = 1152 - 384 = 768 litres

6th day = 1/3rrd of 768 litres is removed

\( = \dfrac{768}{3} = 256 \)

Amount of water left = 1768 - 256 = 512 litres

So, 512 litres water remains in the tank at the end of 6 days

Answer:

a) 0.857

b) 0.571

c) 1

Step-by-step explanation:

Based on the data given, we have

18 juniors

10 seniors

6 female seniors

10-6 = 4 male seniors

12 junior males

18-12 = 6 junior female

6+6 = 12 female

4+12 = 16 male

A total of 28 students

The probability of each union of events is obtained by summing the probabilities of the separated events and substracting the intersection. I will abbreviate female by F, junior by J, male by M, senior by S. We have

P(J U F) = P(J) + P(F) - P(JF) = 18/28+12/28-6/28 = 24/28 = 0.857

P(S U F) = P(S) + P(F) - P(SF) = 10/28 + 12/28 - 6/28 = 16/28 = 0.571

P(J U S) = P(J) + P(S) - P(JS) = 18/28 + 10/28 - 0 = 1

Note that a student cant be Junior and Senior at the same time, so the probability of the combined event is 0. The probability of the union is 1 because every student is either Junior or Senior.

The probability that a randomly selected student from the class is a male or a junior = 33/40 or 0.825

The probability of an event is a fractional value representing the chance of the event taking place. The probability of event A can be determined by the ratio of the number of outcomes favorable to event A, to the total number of outcomes.

We are informed that in a statistics class, there are 22 juniors and 18 seniors. Of the juniors, 12 are females. Of the seniors, 11 are males.

We are asked to find the probability that a randomly selected student from the class is a male or a junior.

To find the probability, we first need to find the number of juniors or males in the class.

The number of juniors = 22.

The number of males = (22-12) + 11 = 10 + 11 = 21 {Taking (22 - 12) as there are 12 females among the 22 juniors}

Now, we have counted male juniors in both cases.

The number of male juniors = 22 - 12 = 10.

∴ Total number of favorable outcomes = The number of juniors + The number of males - The number of male juniors = 22 + 21 - 10 = 33.

Total number of outcomes = Total students = 22 + 18 = 40

∴ The probability that a randomly selected student from the class is a male or a junior = Total number of favorable outcomes/Total number of outcomes = 33/40 or 0.825

Pick good values for "x" that will make the evaluation easy (for example the number "0" and also multiples of "3":

when x = 0  then y = 0/3 - 4 = -4   then the point is (0, -4)

when x = 3 then y = 3/3 -4 = 1 - 4 = -3  then this new point is (3, -3)

The average rate of change of f over the interval [12, 16] is approximately 0.331.

What is the average rate of change?

The average rate of change of a function f(x) over an interval [a, b] is given by the formula:

Average Rate of Change = (f(b) - f(a))/(b - a)

In this case, we are given the function f(x) = √ x + 5, and the interval [12, 16]. Therefore, the average rate of change of f over this interval is:

(f(16) - f(12))/(16 - 12)

= (√16 + 5 - √12 + 5)/4

= (√21 - √17)/4

≈ 0.331

Therefore, the average rate of change of f over the interval [12, 16] is approximately 0.331.

Answer:

  (b) dilation by 2, reflection in y-axis

Step-by-step explanation:

Each of the dimensions of ΔA'B'C' is double the corresponding dimension of ΔABC, so dilation by a factor of 2 has occurred.

The sequence of vertices in ΔA'B'C' is CCW, opposite that of ΔABC. Hence, a reflection has taken place. (Rotation keeps the same order.)

The transformation is a dilation by a factor of 2 and a reflection across the y-axis.

24.99

Step-by-step explanation:

If the area of the quarter circle is 38.465, then the equation to find this would be

3.14*r^2 / 4 = 38.465. we solve for r, the radius, and get two solutions. 7 and -7. Obviously the length of the radius can't be -7, so we know the radius is 7.

Now we must solve for the perimeter. The perimeter is equal to 2r + (2*3.14*r)/4

Plugging 7 in as the radius, r, we get 24.99 as our final answer.
