Why do we use two supply curves in the aggregate goods and services market? What is the difference between them, and why do they have different slopes?

Answer: the length of the cable is 10000 feet.

Step-by-step explanation:

A right angle triangle is formed. The length of the cable represents the hypotenuse of the right angle triangle. The height of the mountain represents the opposite side of the right angle triangle. To determine the length of the cable, L, we would apply the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin 30 = 5000/L

L = 5000/Sin 30 = 5000/0.5

L = 10000 ft

Answer:

Area of triangle = 1/2 × base × height

Step-by-step explanation:

The two big traingles have same dimensions..

its height = 24ft

base=32 ft

so area of one big traingle = 1/2 × 32 × 24

= 384

similarly area of another big traingle = 384 as it has same dimensions.

now one small traingle... both have same dimension

its base =7

height=24

its area = 1/2 × 7 ×24

= 84

another small traingle area similarly = 84

Total area = 384+ 384 +84+ 84

Answer:

5

Step-by-step explanation:

(4+20+x)/3 = (y+16)/2

2(24+x) = 3(y+16)

48 + 2x = 3y + 48

2x = 3y

Since x and y are positive integers, they can't be 0. To satisfy 2x = 3y

We'll have to use LCM of 2 and 3, which is 6 (or a multiple of 6)

For the least value, we use 6

To make both sides 6,

x = 3 and y = 2

Hence x + y = 5

Answer:

3 books per box, 3 left over.

Step-by-step explanation:

Brian has 18 books, and he is packing them into 5 boxes. 18 is only divisible by 1, 3, 9, and 18.

1 x 5 = 5 books =  13 left over. Still enough to pack more books.

3 x 5 = 15 books = 3 left over. This is the answer, but let's check the others as well.

9 x 5 = 45 books. He doesn't have that many! He can't put 9 books in each box because it would only take 2 boxes he's using all 5.

18 x 5 = 90 books. We can clearly see this isn't the answer. He would only be able to put all 18 books in 1 box but he wants to use all 5 boxes.

There are 3 books in each box with 3 left over.

Brian has 3 books in each of the 4 boxes, with 3 books remaining as leftovers after packing them equally.

Brian is moving his 18 books and has packed an equal number of books into each of the 5 empty boxes. To find out how many books are in each box, we divide the total number of books by the number of boxes, which is = 18 books ÷ 5 boxes = 3 books per box with 3 books left over. Therefore, there will be 3 full boxes and one box with 3 leftover books.

Answer: 16

Step-by-step explanation:

law of cosines says that c^2 = a^2 + b^2 -2abcosC

so c^2 = 3^2 +15^2 - 2*2*15*cos108

Answer: the rate of the cabin cruiser in calm water is 12 mph.

the rate of the current is 3 mph.

Step-by-step explanation:

Let x represent the rate of the cabin cruiser in calm water.

Let y represent the rate of the current.

A cabin cruiser traveling with the current went 45 miles in 3 h. This means that the total speed is (x + y) miles per hour.

Distance = speed × time

Distance travelled with the current is

45 = 3(x + y)

Dividing through by 3, it becomes

15 = x + y - - - - - - - - - - -1

Traveling against the current it took 5 hours to go the same distance. This means that the total speed is

(x - y) miles per hour.

Distance travelled against the current is

45 = 5(x + y)

Dividing through by 5, it becomes

9 = x - y - - - - - - - - - - -2

Adding equation 1 to equation 2, it becomes

24 = 2x

x = 24/2

x = 12 mph

Substituting x = 12 into equation 1, it becomes

15 = 12 + y

y = 15 - 12

y = 3 mph

      Rate of the cabin cruiser will be 12 miles per hour and the rate of the current is 3 miles per hour.

  Let the speed of the current = r miles per hour

And the speed of the cabin cruiser in the calm water = c miles per hour

Speed of the cabin cruiser against the current = (c - r) miles per hour

Speed of the cabin cruiser with the current = (c + r) miles per hour

Since, expression for the speed is given by,

Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

Therefore, speed of the cabin cruiser with the current = [tex]\frac{45}{3}[/tex] = 15 miles per hour

So the equation for the speed will be,

c + r = 15 ------ (1)

Time taken to cover 45 miles against the current = 5 hours

Therefore, equation for this situation will be,

c - r = [tex]\frac{45}{5}[/tex]

c - r = 9 ------- (2)

Now solve this system of equations,

Add equation (1) and (2),

(c + r) + (c - r) = 15 + 9

2c = 24

c = 12 miles per hour

Substitute the value of 'c' in equation (1),

12 - r = 9

r = 12 - 9

r = 3 miles per hour

     Therefore, speed of the cabin cruiser will be 12 miles per hour and the rate of the current is 3 miles per hour.

Answer:

The afrmer had 480 chickens at first

Step-by-step explanation:

We make an assumption here, that the initial number of chickens that the farmer has, is C.

Chickens sold by the farmer is (20% of C) + 240 chickens

Number of chickens left after selling in the morning and afternoon is 30% of C

So, the first number of chickens = Number of chickens sold + Number of chickens left

This gives us an equation that will be solved to obtain C.

C = ([tex]\frac{20}{100}[/tex] × C) + 240 chickens + ([tex]\frac{30}{100}[/tex] × C) = 0.2C + 240 chickens + 0.3C

C = 0.5C + 240 chickens

C - 0.5C = 240 chickens

0.5C = 240 chickens

Answer: y = 6

y = -3x - 12

y = 3x + 24

Use elimination method to get 2y = 12 so y = 6.

Answer: the last option is the correct answer.

Step-by-step explanation:

The given system of equations is expressed as

y = - 3x - 12- - - - - - - - - - - - -1

y = 3x + 24- - - - - - - -- - - - - - -2

We would apply the method of elimination. Since x has the same coefficient and the sign is opposite, we would eliminate x by adding equation 1 to equation 2. It becomes

y + y = - 3x + 3x - 12 + 24

2y = 12

Dividing the left hand side and the right hand side of the equation by 2, it becomes

2y/2 = 12/2

y = 6

2.Why did people initially believe that a horse named "Clever Hans" could do math and that a procedure called "facilitated communication" could enable autistic children to type out complex messages?

A.In both cases, the unusual behavior was initially demonstrated under carefully controlled conditions

B.In both cases, scientists falsified their data

C.In both cases, people initially failed to recognize alternative explanations for the observed behavior

D.Both cases were very elaborate hoaxes designed by con artists who were intentionally trying to fool people

People believed in Clever Hans' mathematical abilities and in facilitated communication for autistic children due to misinterpretation of cues and expectations, known as the Clever Hans Effect and the influence of facilitators, respectively.

People initially believed that a horse named Clever Hans could do math and that a procedure called facilitated communication could enable autistic children to type out complex messages due to a misunderstanding of the animals' and participants' capabilities.

Regarding Clever Hans, the horse's trainer, Wilhelm von Osten, would ask Hans a math problem, to which the horse would tap out the answer with his hoof.

It was discovered that Hans was not performing mathematical calculations; rather, he was responding to physical and perhaps subconsciously given cues from his human observers, a phenomenon now known as the Clever Hans Effect.

Similarly, efforts to interpret autistic children's communications were influenced by the expectations and subtle suggestions from the facilitators in facilitated communication.

Three quizzes worth 50 points each = 3 X 50 =150 points

Final exam worth 200 points

Total Obtainable Points=300+150+200=650

Total of test grades obtained (91, 82, and 88)=91+82+88=261

Total of quiz grades (50, 42, and 42) obtained = 50+42+42=134

Answer: the area of the garden is 493 ft²

Step-by-step explanation:

Let L represent the length of the rectangular garden.

Let W represent the width of the rectangular garden.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If he has 92 feet of fencing, it means that

2(L + W) = 92

Dividing through by 2, it becomes

L + W = 46 - - - - - - - - - - - -1

He wants the length of the garden to be five feet less than twice its width. This means that

L = 2W - 5

Substituting L = 2W - 5 into equation 1, it becomes

2W - 5 + W = 46

2W + W = 46 + 5

3W = 51

W = 51/3

W = 17 feet

L = 2W - 5 = 2 × 17 - 5

L = 29 feet

The area of the garden is

LW = 29 × 17 = 493 ft²

Given : An equation for the depreciation of a car is given by [tex]y = A(1-r)^t[/tex], where y = current value of the car, A = original cost, r = rate of depreciation, and t = time, in years. The value of a car is half what it originally cost. The rate of depreciation is 10%.

To find : Approximately how old is the car?

Solution :

The value of a car is half what it originally cost i.e. [tex]y=\frac{1}{2} A[/tex]

The rate of depreciation is 10% i.e. r=10%=0.1

Substitute in the equation, [tex]y = A(1-r)^t[/tex]

[tex]\frac{1}{2} A= A(1-0.1)^t[/tex]

[tex]\frac{1}{2}= (0.9)^t[/tex]

Taking log both side,

[tex]\log(\frac{1}{2})=t\log (0.9)[/tex]

[tex]t=\frac{\log(\frac{1}{2})}{\log (0.9)}[/tex]

[tex]t=6.57[/tex]

[tex]t\approx 6.6[/tex]

Therefore, the car is about 6.6 years old.

Answer:

The car is 6.5 years old

Step-by-step explanation:

An equation for the depreciation of a car is given by [tex]y = A(1 - r)^t[/tex]

y = current value of the car

A = original cost

r = rate of depreciation

t = time in years

The value of a car is half what it originally cost

So, [tex]y = \frac{A}{2}[/tex]

The rate of depreciation is 10% = 0.1 =r

Substitute the values in equation

[tex]\frac{A}{2} = A(1 - 0.1)^t[/tex]

[tex]\frac{1}{2} =(1 - 0.1)^t[/tex]

[tex]\frac{1}{2} =(0.9)^t[/tex]

[tex]0.5=0.9^t[/tex]

t=6.57

Hence The car is 6.5 years old

Answer:

172 ft

Step-by-step explanation:

Due south and due east form a 90-degree angle.

Her path is a right triangle. The 60 ft and 40 ft distances are the legs of the right triangle. We can use the Pythagorean theorem to find the hypotenuse. Then we add the lengths of the three sides to find the total distance she traveled which is the perimeter of the right triangle.

a^2 + b^2 = c^2

(40 ft)^2 + (60 ft)^2 = c^2

1600 ft^2 + 3600 ft^2 = c^2

c^2 = 5200 ft^2

c = 72 ft

perimeter = a + b + c = 40 ft + 60 ft + 72 ft = 172 ft

Answer: total distance is 172 feet

Step-by-step explanation:

The different directions along which Maria moved forms a right angle triangle.

The diagonal distance, h across the ring back to where she started represents the hypotenuse of the right angle triangle. The distances due south and east represents the opposite and adjacent sides of the right angle triangle.

To determine h, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore,

h² = 60² + 40²

h² = 5200

h = √5200

h = 72 feet

The total distance, to the nearest foot, maria skates is

72 + 60 + 40 = 172 feet

If the segments bisect each other, they will share the same midpoint.

Midpoint formula is:

(x, y) = ((x₁ + x₂)/2, (y₁ + y₂)/2)

Midpoint of MN is:

(x, y) = ((-5 + 5)/2, (6 + -2)/2)

(x, y) = (0, 2)

Midpoint of PQ is:

(x, y) = ((5 + -5)/2, (3 + 1)/2)

(x, y) = (0, 2)

So the segments do bisect each other.
