Answers

Answer:

M=12

Step-by-step explanation:

The required length of MN in the given triangle LMN is 16 units.

What is a triangle?

A polygon with three vertices, angles and sides is called a triangle.

Given that, a triangle △ LMN, where, ∠ M ≅ ∠ L, LM = 7 and LN = 16

Since, ∠ M ≅ ∠ L

Therefore, MN ≅ LN

By the postulate :-

Sides opposite to congruent angles of a triangle are also congruent.

Therefore,

MN = LN

Since, LN = 16

Therefore, MN = 16 [By transitive property]

Hence, the required length of MN in the given triangle LMN is 16 units.

If an AaBbccDd individual is crossed to a AaBbCcDD individual, what is the probability that the first offspring will be of AabbccDd genotype?

Answers

Answer:

The probability that the first offspring will be of AabbccDd genotype is 0.03125.

Step-by-step explanation:

The parents genotype are: AaBbccDd and AaBbCcDD.

Aa and Aa

         A           a

A      AA         Aa

a       Aa         aa

P (Aa) = 2/4 = 1/2

Bb and Bb

         B           b

B      BB         Bb

b      Bb         bb

P (bb) = 1/4

Cc and cc

         c           c

C      Cc         Cc

c       cc         cc

P (cc) = 2/4 = 1/2

Dd and DD

         D           d

D      DD        Dd

D      DD        Dd

P (Dd) = 2/4 = 1/2

Then the probability that the first offspring will be of AabbccDd genotype is:

P (AabbccDd) = (1/2) × (1/4) × (1/2) × (1/2) = 1/32

Thus, the probability that the first offspring will be of AabbccDd genotype is 0.03125.

box with a square base and open top must have a volume of 4,000 cm3. Find the dimensions of the box (in cm) that minimize the amount of material used. sides of base

Answers

Answer:

Hence the width, length is 20 cm and height is 10 cm

Step-by-step explanation:

Since the box has a square base, let length = width = x. Also, let the height = y, therefore:

The volume of box = width * length * height

4000 = x * x * y

4000 = x²y

y=4000/x²

The surface area (SA) = area of the base + sum of the area of each side

SA = x² + xy + xy + xy + xy

SA = x² + 4xy

substitute y = 4000/x²

SA = x² + 4x(4000/x²)

SA = x² + 16000/x

Taking the derivative:

SA' = 2x - 16000/x²

making SA' = 0:

0 = 2x - 16000/x²

2x = 16000/x²

2x³ = 16000

x³ = 8000

x = 20 cm

y = 4000 / x² = 4000 / 20² = 10 cm

Hence the width, length is 20 cm and height is 10 cm

How much money did Susan earn per hour?

Answers

Susan earns $11.50 per hour.

The correct answer is option (D).

What is rate in mathematics?

"It is the ratio or comparison of two related quantities."

What is proportional in mathematics?

"When one quantity is proportional to other quantity, this means with increase in the values of first quantity there is equal increase/decrease in the values of second quantity."

For given situation,

Susan's weekly earnings were proportional to the number of hours she worked.

From given table, we can observe that with increase in the number of hours Susan worked, there in increase in the weekly earnings.

This means, Susan's weekly earnings are directly proportional to the number of hours she worked.

We need to find the amount of money she earn per hour, i.e., to find the ratio of her total earnings and total hours she worked.

Let S represents Susan's total earning and T represents the total number of hours she worked.

⇒ S = 57.50 + 80.50 + 103.50 + 126.50

⇒ S = 368

And T = 5+ 7 + 9 + 11

⇒ T = 32

Now we find the required ratio,

S/T = 368/T

⇒ S/T = 11.5 dollar per hour

Therefore, Susan earn $11.5 per hour.

Hence, option (D)$11.50 is the correct option.

Now there is a door whose height is more than its width by 6 chi 8 cun. The distance between the [opposite] corners is 1 zhang. Find the height and width of the door.NOTE: 1 zhang

Answers

Complete question is;

Now there is a door whose height is more than its weight by 6 chi 8 cun. The distance is between the opposite is corners is 1 zhang. Find the height and width of the door.

Note: 1 zhange = 10 chi = 100 cun. Give your answers in units of chi and cun.

Answer:

h = 9 chi 6 cun

w = 2 chi 8 cun

Step-by-step explanation:

Let the height be h and width be w.

Now, we are told that height is more than its weight by 6 chi 8 cun.

Thus,

weight = height - 6 chi 8 cun

Let's convert 6 chi 8 cun to chi for easy calculation.

Since 100 cun = 10 chu

Then 8 cun = 8 × 10/100 = 0.8 chi

Thus 6 chi 8 cun = 6 chi + 0.8 chi = 6.8 chi

Thus;

Height is h

Width is (h - 6.8) chi

Now, we are told that the distance between the corners is 1 zhang = 10 chi

Distance between corners is the diagonal of the door.

Thus, the height, width and diagonal con form a right angle triangle which can be solved by Pythagoreas theorem.

Thus;

h² + w² = 10²

Plugging in (h - 6.8) for w, we have;

h² + (h - 6.8)² = 100

h² + h² - 13.6h + 46.24 = 100

2h² - 13.6h + 46.24 - 100 = 0

2h² - 13.6h - 53.76 = 0

Using quadratic formula, we have;

h = 9.6 chi

Converting 0.6 chi to cun gives;

0.6 × 100/10 = 6 cun

Thus, h = 9 chi 6 cun

Since w = (h - 6 chi 8 chun)

Then, w = 9 chi 6 cun - 6 chi 8 chun = 2 chi 8 chun
