Jill counts 150 peach trees on 1/2 of the land she owns. She determines that there are 5 trees for every 1,000 square feet of land. About how many acres of land does Jill own? 1 acre= 43,560 square feet.

Answer:

x=115 y=65

Step-by-step explanation:

You get 115 for X because angle x is vertical to 115 degrees.

You get 65 because y is supplementary to x, and 180-65=115.

Answer:

x = 115 degree and y = 65 degree

Step-by-step explanation:

Here we can see

x = 115 ( being vertically opposite angles )

So Now

x + y = 180 ( being linear pair )

115 + y = 180

y = 180 - 115

Therefore  y = 65

Answer:

P43=4!(4–3)!=241=24 24 possible choices

Step-by-step explanation:

There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.

This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:

P43=4!(4–3)!=241=24

(a) Equilibrium point: x = 1

(b) Consumer surplus at equilibrium: 0

(c) Producer surplus at equilibrium: 0

We have,

To find the equilibrium point, we need to set the demand (D(x)) equal to the supply (S(x)):

D(x) = S(x)

Given:

D(x) = (x - 7)^2

S(x) = x^2 + 4x + 31

(a) Equilibrium point:

Setting D(x) equal to S(x):

(x - 7)^2 = x^2 + 4x + 31

Expanding and rearranging the equation:

x^2 - 14x + 49 = x^2 + 4x + 31

Simplifying and rearranging further:

-14x - 4x = 31 - 49

-18x = -18

x = 1

Therefore, the equilibrium point is x = 1.

(b) Consumer surplus at the equilibrium point:

Consumer surplus represents the difference between the price consumers are willing to pay and the price they actually pay.

At the equilibrium point, the price consumers are willing to pay (D(x)) is equal to the price they actually pay (S(x)).

Substituting x = 1 into the demand function D(x):

D(1) = (1 - 7)^2

D(1) = (-6)^2

D(1) = 36

Consumer surplus at the equilibrium point is the difference between what consumers are willing to pay and what they actually pay:

Consumer surplus = D(x) - S(x)

Consumer surplus = 36 - S(1)

Consumer surplus = 36 - (1^2 + 4(1) + 31)

Consumer surplus = 36 - (1 + 4 + 31)

Consumer surplus = 36 - 36

Consumer surplus = 0

Therefore, at the equilibrium point, the consumer surplus is 0.

(c) Producer surplus at the equilibrium point:

Producer surplus represents the difference between the price producers are willing to accept and the price they actually receive.

At the equilibrium point, the price producers are willing to accept (S(x)) is equal to the price they actually receive (D(x)).

Substituting x = 1 into the supply function S(x):

S(1) = 1^2 + 4(1) + 31

S(1) = 1 + 4 + 31

S(1) = 36

Producer surplus at the equilibrium point is the difference between what producers are willing to accept and what they actually receive:

Producer surplus = S(x) - D(x)

Producer surplus = 36 - D(1)

Producer surplus = 36 - (1 - 7)^2

Producer surplus = 36 - (-6)^2

Producer surplus = 36 - 36

Producer surplus = 0

Therefore, at the equilibrium point, the producer surplus is also 0.

Thus,

(a) Equilibrium point: x = 1

(b) Consumer surplus at equilibrium: 0

(c) Producer surplus at equilibrium: 0

The equilibrium point in the market occurs when the demand and supply are equal, which can be found by solving the given function equations. Consumer surplus and producer surplus at the equilibrium point are computed as the area between the demand/supply curves and the equilibrium price.

The equilibrium point is when the demand and supply are equal, this happens i.e., D(x) = S(x). Therefore, we first equate (x-7)^2 = x^2 + 4x + 31. Solving this equation gives us the equilibrium quantity, x.
The consumer surplus is the area between the demand curve and the consumer's actual payment, i.e., the area under D(x) above the equilibrium price. This equals to the integral from 0 to x of D(x) minus the equilibrium price. The producer surplus is the area between the supply curve and the consumer's payment, i.e., the area under S(x) below the equilibrium price. This equals to the integral from 0 to x of the equilibrium price minus S(x).

Answer:

-12

Step-by-step explanation:

2 - -4 = 6 --> y + 6 = x

x = -6, so subtract 6 from x to find y

-6 - 6 = -12

y = -12

Does that help?

To find y when x = -6, given that y varies directly with x and y = -4 when x = 2, we first calculate the proportionality constant k, and then use it to find the new value of y.

If y varies directly with x, this means that y can be expressed as y = kx, where k is the proportionality constant. Given that y = -4 when x = 2, we can first find the value of k by substituting these values into the direct variation equation:

-4 = k(2)

From this, we can solve for k:

k = -2

Now, to find y when x = -6, we substitute -6 for x in the original direct variation equation y = kx, using our found value of k:

y = (-2)(-6)

y = 12

Therefore, when x = -6, y will be 12.

Answer: the speed of the plane in still air is 101.2 mph

Step-by-step explanation:

Let x represent the speed of the plane in still air.

The pilot flew his​ single-engine airplane 60 miles with the wind from City A to above City B. If the wind was a constant 30 miles per​ hour, it means that the total speed at which he flew the plane while going is (x + 30) mph.

Time = distance/speed

Time spent while going is

60/(x + 30)

He then turned around and flew back to City A against the wind. it means that the total speed at which he flew the plane while returning is (x - 30) mph.

Time spent while returning is

60/(x - 30)

If the total time going and returning was 1.31.3 ​hours, it means that

60/(x + 30) + 60/(x - 30) = 1.3

Cross multiplying, it becomes

60(x - 30) + 60(x + 30) = 1.3(x - 30)(x + 30)

60x - 1800 + 60x + 1800 = 1.3(x² + 30x - 30x - 900)

120x = 1.3x² - 1170

1.3x² - 120x - 1170 = 0

The general formula for solving quadratic equations is expressed as

x = [- b ± √(b² - 4ac)]/2a

From the equation given,

a = 1.3

b = - 120

c = - 1170

Therefore,

x = [- - 120 ± √(- 120² - 4 × 1.3 × - 1170)]/2 × 1.3

x = [120 ± √(14400 + 6080)]/2.6

x = [120 ± √20480]/2.6

x = (120 + 143.1)/2.6 or x = (120 - 143.1)/2.6

x = 101.2 or x = - 8.9

Since the speed cannot be negative, then x = 101.2 mph

Answer: The area of the square is increasing at a rate of 90.4 m2/min (square meters/minute)

Step-by-step explanation: Please see the attachments below

Answer:

The area of the square is increasing at 90.51m^2/min

Step by step explanation:

Given;

Change in diagonal length ∆d = 8m/min

Length l = 8m

When l = 8m

d^2 = 2l^2 = 2×8^2 = 128

d = √128

Area of a square = l^2 = (d^2)/2

d = diagonal

Change in area = ∆A = dA/dd

∆A = 2 × d/2 × ∆d = d×∆d

∆A = √128 × 8 = 90.51m^2/min

Final answer:

The approximate square root of 48 is found by locating it between the perfect squares of 36 (6²) and 49 (7²), leading to a closer estimation of about 6.9 when considering 48 as 16 * 3 and simplifying.

Explanation:

The question asks to find the approximate square root of 48. To do this, we first recognize that the exact square root of 48 is not a whole number, and therefore, we need to find two perfect squares between which 48 lies. The perfect squares closest to 48 are 49 (7²) and 36 (6²). Since 48 is closer to 49, we can estimate that the square root of 48 is slightly less than 7. A more refined method involves thinking of 48 as 16 * 3, which then gives us √16 * √3 = 4√3. Knowing that √3 is approximately 1.732, we can multiply this by 4 to get an approximation of 6.928. Therefore, a good approximation for the square root of 48 is approximately 6.9.

Answer:

Eli has saved $10

Step-by-step explanation:

Let us use the first letters of their names to represent them.

A for Angela and E for ELi

So, from the first statement, we can write out an equation: E = [tex]\frac{1}{3}[/tex]A + 8, that is, one-third of Angela's savings + $8 will give us Eli's savings

From the second statement, we can write out: E + 10 = (A + 10) + 4 which means that if $10 is added to both their savings, Eli will still have $4 more than Angela.

So, we can solve both equations;

Equation 1: E = [tex]\frac{1}{3}[/tex]A + 8

Equation 2: E + 10 = (A + 10) + 4; which can be rewritten as E + 10 = A + 14

and then E = A + 4

The two equations (in bold), can then be solved simultaneously.

Let us carry out this operation to eliminate the E: Subtract equation 1 from equation 2, so that;

A + 4 - ( [tex]\frac{1}{3}[/tex]A + 8) = E - E

[tex]\frac{2}{3}[/tex]A - 4 = 0

[tex]\frac{2}{3}[/tex]A = 4

A = 4 × [tex]\frac{3}{2}[/tex] = 6

So, if A is 6, and E = A + 4 (from equation 2, that means that E = 6 + 4 = 10

So, Eli has saved $10, while Angela has saved $6.

If we check what was said in the question about their savings, which is what we have represented using the equations, the answers can be confirmed.

Answer:

Eli has saved $10

Step-by-step explanation:

 Let us denote Angela's saving by "x".

  If Eli's saving is $8 more than one-third of Angela's saving, then Eli's saving   is:

 [(1/3 × x) + 8 = x/3 + 8]

 We will make x/3 + 8 to have a common denominator:

 x/3 + 8 = (x+24)/3

 If Eli and Angela each saved $10 more, then their respective savings would have been:

(x+24)/3  +  10 for Eli

x+10 for Angela.

At this savings, Eli would have been $4 richer than Angela.

i.e   [((x + 24)/3) + 10] -  (x+10) = $4

 We will make [(x+24)/3] + 10 to have common denominator.

(x + 24 + 30)/3

= (x + 54)/3

 Then:

  [(x+54)/3]  -  [(x+10)/1] = 4

   [x+54-(3x+30)]/3 = 4/1

    (-2x + 24)/3 = 4

    cross multiply

  -2x + 24 = 12

    -2x = -12

       x = -12/-2

       x = 6

  Since Eli's saving = x/3 + 8

Then his actual saving

  = 6/3 + 8

  = 2 + 8

  = $10

Answer:

The translation rule is (x , y) → (x - 12 , y - 4)

Step-by-step explanation:

Let us revise the translation of a point

An object is translated from A (-6, -4) to A' (-18, -8)

∵ A is (-6 , -4)

∵ A' is (-18 , -8)

∴ x-coordinate = -6

∴ x'-coordinate = -18

- By using the translation rule above

∵ x' = x + h

∴ -18 = -6 + h

- Add 6 to both sides

∴ -12 = h

∴ h = -12

∵ h is a negative value

- That means A translated to the left 12 units

∴ The rule is (x , y) → (x - 12 , y)

∵ y-coordinate = -4

∴ y'-coordinate = -8

∵ y' = y + k

∴ -8 = -4 + k

- Add 4 to both sides

∴ -4 = k

∴ k = -4

∵ k is a negative value

- That means A down 4 units

∴ The rule is (x , y) → (x , y - 4)

The translation rule is (x , y) → (x - 12 , y - 4)

Answer:

try 45

Step-by-step explanation:

The water level rises at a rate of approximately 2.83 cm per minute. Therefore, the water level would be approximately 34 cm after 12 minutes.

This problem involves the concept of linear relationships and slopes in mathematics. Given that the water level rises by 17 cm every 6 minutes, we can find the rate of increase per minute by dividing 17 cm by 6 minutes. This value, approximately 2.83 cm/minute, is the slope of the linear relationship.

This means each additional minute increases the water level by about 2.83 cm. If we denote the time as x and the water level as y, the linear equation expressing this relationship can be written as y = 2.83x.

To find the value of y when x (time) is 12 minutes, we substitute x = 12 into this equation. So, y = 2.83 * 12 = 33.96 cm. Therefore, the water level would be close to 34 cm after 12 minutes.

The angle that must also measure 130° is angle 4.

Angle 4 must also measure 130°. When two lines intersect, the vertically opposite angles are congruent, meaning angle 1 and angle 4 are equal. Therefore, if angle 1 measures 130°, angle 4 must also measure 130°.

If angle 1 measures 130°, angle 3 must also measure 130°.

When two lines intersect, they form pairs of angles known as vertical angles or vertically opposite angles. These angles are congruent, meaning they have the same measure. The key property of vertical angles is that they are formed by opposite rays.

In the given scenario:

Angle 1 and angle 3 are vertically opposite angles because they are formed by the intersecting lines and share the same vertex.

Since angle 1 measures 130°, according to the properties of vertical angles, angle 3 must have the same measure.

This is a fundamental property of vertical angles: they are always congruent. Therefore, if angle 1 measures 130°, angle 3 must also measure 130°.

The probability of drawing at least one face card when drawing two cards with replacement from a standard deck is approximately 0.407.

The student is asking for the probability of drawing at least one face card (Jack, Queen, or King) when drawing two cards with replacement from a standard deck of 52 cards. To find this, we can use the complement rule: subtract the probability of not drawing a face card in both draws from 1. There are 12 face cards in a deck of 52 cards, so the probability of drawing a non-face card (event N) on one draw is 40/52 (since there are 40 non-face cards).

Using the complement rule:

Now perform the calculations:

P(NN) = (40/52) * (40/52) = 0.5929 (approximately).

P(at least one F) = 1 - 0.5929 = 0.4071 (rounded to three decimal places).

Therefore, the probability of drawing at least one face card in two draws with replacement is approximately 0.407.

The midpoint of the segment with endpoints (-1, 5) and (-6, -2) is calculated using the midpoint formula and is (-3.5, 1.5).

The question seems to be asking for the midpoint of a segment with given endpoints. However, the numbers provided (-1, 5, -6, -2) do not clearly define a specific segment in a conventional two-dimensional coordinate system. Typically, a line segment in two-dimensional space is represented by the coordinates of its endpoints, such as (x₁, y₁) and (x₂, y₂).

If we assume the numbers are pairs of coordinates, we could interpret them as the endpoints (-1, 5) and (-6, -2). To find the midpoint of a segment with endpoints (x₁, y₁) and (x₂, y₂), you use the midpoint formula: Midpoint M = [tex](\frac{x_1 + x_2}{ 2}, \frac{y_1 + y_2}{2})[/tex]

Applying this to the given points: M = [tex](\frac{-1 + (-6)}{ 2}, \frac{5 + (-2)}{ 2} = (\frac{-7}{ 2}, \frac{3 }{ 2})[/tex] = (-3.5, 1.5).

The midpoint of the segment with endpoints (-1, 5) and (-6, -2) is (-3.5, 1.5).

Answer:

hot dogs- $1.25

hamburgers- $1.50

Step-by-step explanation:

let hot dogs be x and hamburgers be y∀

five hot dogs and two hamburgers cost $9.25

5x + 2y = $9.25 (eq. 1)

5x=9.25-2y

divide both sides by 5x

x= 1.85-0.4 (insert this in eq. 2)

two hotdogs and five hamburgers cost $10.00

2x + 5y = $10.00 (eq. 2)

2×(1.85-0.4) +5y=10.00

3.7 - 0.8 + 5y = 10.00

-0.8+5y=10.00-3.7

4.2y=6.3

divide both sides by 4.2 to evaluate the variable

6.3 divided by 4.2

y=1.50
