if michaels family has 210 acres and each cow takes 1/3 acre for grazing,then how many cattle could their farmland support?

Answer:

$21,000

Step-by-step explanation:

The cost of car=$ 28,000

A car is depreciated by 25%

Now, the price of car=$28000(1-)[tex]\frac{25}{100}[/tex]

The price of the car= $28000([tex]\frac{100-25}{100}[/tex])

The price of the car= $28000([tex]\frac{75}{100}[/tex])

The price of the car= $280×75

The price of the car= $21,000

The car worth today $21,000

Hence the correct answer is $ 21,000

Set up the equations:

2x+3y=80

1x + 4y = 100

solve for x and y:

1x + 4y = 100

x = 100-4y

plug into first equation

2(100-4y)+3y=80

200-8y+3y=80

y=120/5=24

x = 100-4y=100-96=4

So the charges are (x,y)=(4,24)

So the correct answer (B)

(1, 3 )

to determine if the given points are a solution to the equation

They must lie on the given line to be a solution

the only one that is on the line is (1, 3 ) and is therefore the only solution

B

since both equations express y in terms of x we can equate the right sides

2x + 7 = 25 - x ( add x to both sides )

3x + 7 = 25 ( subtract 7 from both sides )

3x = 18 ( divide both sides by 3 )

x = 6

substitute x = 6 into either of the 2 equations for y

y = 2x + 7 = ( 2 × 6 ) + 7 = 12 + 7 = 19

solution is (6, 19 )

The value for X, the measure of angle MKL, is not specifically given in the question. Since angle JKL is a straight angle of 180 degrees, X can be any value up to 180 degrees.

In mathematics, a straight angle is defined as an angle of 180 degrees. In the scenario described with angle JKL, it is mentioned that this is a straight angle. Given that angle MKL is a part of the straight angle, its degree measure X is a component of those 180 degrees. The specific value of X is not given in the question, and it can be any number less than or equal to 180, provided the other part of the angle KJM is equal to 180- X.

The measure of angle MKL is 60 degrees.

Finding the Measure of Angle MKL

To determine the value of X in this problem, we first need to understand that a straight angle measures 180 degrees. The problem states that angle JKL is a straight angle, so:

Angle JKL = 180 degrees

Next, we have the measure of angle JKM given as 120 degrees. Since angle JKL is made up of angle JKM and angle MKL, we can set up the following equation to find the measure of angle MKL, which is X:

Angle JKM + Angle MKL = Angle JKL

Substituting the known values:

120 degrees + X = 180 degrees

To find X, subtract 120 degrees from both sides:

X = 180 degrees - 120 degrees = 60 degrees

Therefore, the measure of angle MKL is 60 degrees.

[ [tex]\frac{1}{2}[/tex](5.5 + 3.75 ), [tex]\frac{1}{2}[/tex](- 4.75 - 2.75 ) ]

Answer:

y = 0.75x+20

Step-by-step explanation:

Given that there is an admission ticket fixed and extra cost of 0.75 per ticket for the rides.

This means even if there is no ride used, enterer has to pay a fixed amount for admission.

Let us find out this admission cost from the given information

If y is the total cost and x no of rides

a) x is the no of rides and y the total cost

b) y = 0.75x+20 is the linear equation to calculate the cost for anyone who only pays for festival admission and rides

(c)

Total cost = Admission charges +0.75 * no of ride tickets.

then y = 0.75x+C

where C is the admission fee

Kendall bought 18 tickets i.e. x= 18 and y = 33.50

33.50 = 0.75(18)+C

33.50=13.50+C

C = 33.50-13.50 = 20.00

Hence admission fee = 20

Yes, you're right! The first step is rewriting the equation as

[tex] \ln(a) + \ln(b^x) = M [/tex]

Subtract [tex] \ln(a) [/tex] from both sides:

[tex] \ln(b^x) = M-\ln(a) [/tex]

Use the property [tex] \ln(a^b) = b\ln(a) [/tex] to rewrite the equation as

[tex] x\ln(b) = M-\ln(a) [/tex]

Divide both sides by [tex] \ln(b)[/tex]

[tex] x = \dfrac{M-\ln(a)}{\ln(b)} [/tex]

Alternative strategy:

Consider both sides as exponents of e:

[tex] e^{\ln(ab^x)} = e^M [/tex]

Use [tex] e^{\ln(x)} = x [/tex] to write

[tex] ab^x = e^M [/tex]

Divide both sides by a:

[tex] b^x = \dfrac{e^M}{a} [/tex]

Consider the logarithm base b of both sides:

[tex] x = \log_b\left(\dfrac{e^M}{a}\right) [/tex]

The two numbers are the same: you can check it using the rule for changing the base of logarithms

To solve ln(a*b^x) = M, apply the log properties to get ln(a) + x*ln(b) = M, isolate x to get x*ln(b) = M - ln(a), and divide by ln(b) to find x = (M - ln(a))/ln(b).

To solve the equation ln(a*b^x) = M for x, begin by applying the property that the logarithm of a product is equal to the sum of the logarithms. That is, ln(xy) = ln(x) + ln(y). Therefore, we can write:

ln(a*b^x) = ln(a) + ln(b^x)

The logarithm of a power allows us to move the exponent to the front of the log, hence:

ln(b^x) = x * ln(b)

Now, our equation becomes:

ln(a) + x * ln(b) = M

We can isolate x by subtracting ln(a) from both sides:

x * ln(b) = M - ln(a)

Finally, divide both sides of the equation by ln(b) to solve for x:

x = (M - ln(a)) / ln(b)

Look for the adjacent letters A.F or F.A in the names of the pair of angles.

The appropriate choice is ...

... BAF and FAD

Answer:

BAF and FAD

Step-by-step explanation:

In order for an angle to have A.F as a side, it must have the letters A.F or FA in its name.

In DAF, the angle is made of rays AD and A.F.  In DAB, the angle is made up of rays AD and AB.  This is not the correct pair.

In EAF, the angle is made of rays AE and A.F.  In CAE, the angle is made up of rays AC and AE.  This is not the correct pair.

In BAF, the angle is made of rays AB and A.F.  In EAD, the angle is made up of rays AE and AD.  This is not the correct pair.

In BAF, the angle is made up of rays AB and A.F.  In FAD, the angle is made up of rays A.F and AD.  This is the correct pair.

The Pythagorean theorem is used for finding the distance between two points. You can consider the line from the origin to (12, 5) to be the hypotenuse of a right triangle with sides 12 and 5 (parallel to the x- and y-axes, respectively). Then the relation between these and the hypotenuse length is

... d² = 12² + 5² = 144 + 25 = 169

... d = √169 = 13

The point (12, 5) is 13 units from the origin.

Okay...... so for this problem you need to use the Pythagorean Theorem. So...

12^2 + 5^2

144+25

169

this = square root of 13

so.... The point (12,5) is 13 units from  the origin.

400/16= 25

In order to solve this problem, we the cost of both to equal each other, so we need to set up two expressions that will equal each other.

Let t = time in months.

The cost of Fab Pool can be represented by the expression 35t + 50

The cost of Perfect Pools can be represented by the expression by 40t + 35.

Now that we have the cost for each, we need to find when they are the same, so we set the expressions equal to each other.

35t + 50 = 40t + 35

Now we solve like a regular equation

50 = 5t + 35

15 = 5t

t = 3

At three months, the cleaning costs will be the same.

Hey there!!

Fab pool service costs $35 per month, this is a variable, the number of month could change and $50 for equipment. And perfect pools cost $40( a variable ) and $35 for equipment.

Let's take the number of month as 'm'.

The question asks us to find the number of months at which both of these costs become equal.

As the question states, we will have to equate both the sums or the values.

Total cost = Cost  for month + Cost for equipment.

Fab pool :

Cost per month = $35

Cost for equipment = $50

Total cost = 35 × ( the number of months ) + 50

Perfect pools :

Cost for month = $40

Cost for equipment = $35

Total cost = 40 × ( the number of months ) + 35

We have taken the number of months as 'm'.

Now, plugging in the values :

Fab pools : 35m + 50

Perfect pools : 40m + 35

Equating this :

... 35m + 50 = 40m + 35

Subtracting 35m on both sides :

... 50 = 5m + 35

Subtracting 35 on both sides:

... 15 = 5m

Dividing by 5 on both sides :

... m = 3

Hence, the number of months is 3.

Hope it helps!!

Answer:

Given: A Δ ABC in which , AB ≅ BC, BE − median of ΔABC, m∠ABE = 40°30'

To Find: ∠ABC, ∠ CE B,∠A E B

Solution: In Δ ABC , BE is the median.

So, AE= EC

Now, In Δ A E B and Δ CE B

AE = EC [ BE is median]

BE is common.

AB=BC [given]

Δ A E B ≅Δ CE B { SSS Congruency]⇒S→side

So, ∠ABE=∠C BE  [ C PCT]

∴ ∠ABC=2×∠ABE=2×40°30'=81°

∠B EA =∠C E B [ C P CT]

Also,∠B A C = ∠BC A=k° [As AB =BC , if opposite sides are equal , then angle opposite to them are equal]

∠A+ ∠B+∠C=180°[ angle sum property of triangle]

k°+81°+k°=180°

2 k°=180°-81°

2 k°=99°

k°=99°/2

k°=49°30'[1°=60']

In Δ A E B, ∠ABE=40°30',∠A=49°30',∠A E B=?

∠ABE+∠A+∠A E B=180°[ angle sum property of triangle]

40°30'+49°30'+∠A E B=180°

90°+∠A E B=180°

∠A E B=180°-90°

∠A E B=90°

As, ∠B EA =∠C E B

So,∠C E B= 90°

So, BE is perpendicular bisector.

The measure of the angle ∠ABC and ∠BCA are both 69°45'. and ∠FEC measures 99°.

∠ABE and ∠BEC are opposite angles formed by the intersecting lines AB and BE, and BC and BE respectively.

Therefore, they are congruent.

The sum of the interior angles of a triangle is always 180°. So, we can find ∠ABE by subtracting ∠BEC from 180°.

Since m∠ABE = 40°30', we have:

∠BEC = ∠ABE = 40°30'

Since AB ≅ BC, the two sides are congruent.

This means that ∠ABC and ∠BCA are also congruent angles. Let's call their measure x.

Using the fact that the sum of the angles in a triangle is 180°, we can set up an equation:

∠ABC + ∠BCA + ∠BAC = 180°

Since ∠BCA = ∠ABC = x, we can substitute these values in:

x + x + 40°30' = 180°

Adding the like terms:

2x + 40°30' = 180°

Subtracting 40°30' from both sides:

2x = 180° - 40°30'

2x = 139°30'

Dividing both sides by 2:

x = 69°45'

So, ∠ABC and ∠BCA are both 69°45'.

To find ∠FEC, we can use the fact that the sum of the angles in a triangle is 180°. Since ∠BEC = ∠ABE = 40°30', we can find ∠FEC:

∠FEC = 180° - ∠BEC - ∠BCE

Substituting the values we know:

∠FEC = 180° - 40°30' - 40°30'

Simplifying:

∠FEC = 180° - 81°

∠FEC = 99°

Therefore, ∠FEC measures 99°.

Assuming you require the measure of the angles

let x represent each equal  base angle then vertex = 7x

The sum of the angles in a triangle = 180°, hence

x + x + 7x = 180

9x = 180 ( divide both sides by 9 )

x = 20

the base angles = 20° and the vertex = 140°

The ratio of the measure of a base angle in an isosceles triangle to the measure of the vertex angle is 1:7. The measure of the base angle is 1/7 times the measure of the vertex angle.

In an isosceles triangle, the base angles are congruent, meaning they have the same measure. Let's denote the measure of the base angle as x degrees and the measure of the vertex angle as y degrees. According to the given ratio, we have the equation:

x : y = 1 : 7

To find the exact measures of the angles, we can set up the equation:

x/y = 1/7

Multiplying both sides by y, we get:

x = y/7

Therefore, the measure of the base angle is 1/7 times the measure of the vertex angle.

Answer: -1 1/8

Step-by-step explanation: When you have a problem like this, you have to divide.

So you turn the improper fraction into a mixed number which (4 1/2 turns into 9/2) and then you do KCF (Keep Change Flip). So you keep the 9/8, change division into multiplication, and since we are going to put the four over a 1 like this 4/1, we need to change it into 1/4. Then you multiply across. 9x1=9 and 2x4=8 so it would be 9/8. But it's an improper fraction right? So you do long division, and you get -1 1/8.
