Th length of the garden when the teacher bought 50 feet of fence is 17 feet.

From the information, the width needs to be the same size as the shed which is 8ft and she bought 50 feet of fence and wants the largest garden she can make,

It should be noted that perimeter is calculated as:

= 2(Length + Width)

In this case, the perimeter is 50 feet.

2(Length + Width) = 50

2(Length + 8) = 50

2L + 16 = 50

2L = 50 - 16

2L =34

Divide

L = 34/3

L = 17 feet.

The length is 17 feet.

In geometry, you can use deductive rules to prove conjectures.

Geometry is defined as a subfield of mathematics that examines the measurement and relationships of surfaces, solids, solid surfaces, angles, and points. The calculation of a triangle's angles is a geometry example.

Geometry will categorize, quantify, and lack a counterexample. Once a concept has been defined, it can be utilized in subsequent definitions; for instance, parallel lines can be used in the definition of a parallelogram once they have been defined. classification, counterexample, quantification, and parallelogram.

In geometry, you can use deductive rules to prove conjectures.

In geometry, deductive rules can be used to demonstrate whether a particular assertion or conjecture is true or untrue. We narrow down a result proving a statement must be true or untrue by using deductive principles, such as definitions, postulates, and other theorems, in a logical order.

The sum of the interior angles of a triangle is always 180°. in this case, the sum is:

Then,

46 + 82 + 50 = 178

Since 178 and 180 are distinct, 46°, 82°and 50°​ can't be the angle measures of a triangle.

Answer:

3671.8, 3576.4

Step-by-step explanation:

The third angle of the triangle is 19°.

Let the first length be a. Then,

[tex] \frac{a}{\sin 85^{\circ}}=\frac{1200}{\sin 19^{\circ}} \\ \\ a=\frac{1200\sin 85^{\circ}}{\sin 19^{\circ}} \approx 3671.8[/tex]

Let the second length be b.

[tex] \frac{b}{\sin 76^{\circ}}=\frac{1200}{\sin 19^{\circ}} \\ \\ b=\frac{1200\sin 76^{\circ}}{\sin 19^{\circ}} \approx 3576.4[/tex]

The slope of the line has increased, meaning it has become a positive number. This shift means that this year the data points were placed higher than the previous year.

The slope of the line is 2 / 3.

The slope of a line can be found as follows:

The slope of a line is change in y with respect to change in x.

In other words, the slope of a line is rise over run.

Therefore,

slope = y₂ - y₁ / x₂ - x₁

Using (0, 3)(-3, 1)

Hence,

x₁ = 0

x₂ = -3

y₁ = 3

y₂ = 1

Therefore,

slope = 1 - 3 / -3 - 0

The greatest number of bouquets they can be divided into if there will be the same number of roses in each bouquet and the same number of tulips in each bouquet is 5.

Given that:-

Number of roses Mary has = 65

Number of tulips Mary has = 104

We have to find the greatest number of bouquets they can be divided into if there will be the same number of roses in each bouquet and the same number of tulips in each bouquet.

HCF (65, 104) = 13

Hence, the groups of 13 roses and 13 tulips will together make a bouquet.

The positive integers that can divide a number evenly are known as the factors in mathematics. Let's say we multiply two numbers to produce a result. The product's factors are the number that is multiplied. Each number has a self-referential element. There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.

The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are called factors. A factor is therefore another number's divisor.

If a telemarketer calls people and tries to sell them a subscription to a daily newspaper. On 25 % of her calls, there is no answer or the line is busy. She sells subscriptions to 9 % of the remaining calls. The proportion of calls she make a sale is: 189/ 25.

Given data ;

Calls without answer or line busy  = 25%

Subscription sold out of remaining calls = 9%

Now let determine the proportion of calls she make a sale :

Proportion = 9 % ×  ( 100 % - 25 %)

Proportion = 9 % × 75 %

Proportion = 7.56 %

Since we were told the  proportion of calls she make a sale we would have to convert the percentage into fraction :

Proportion :

Proportion = 7.56 %

Proportion = 189 / 25  

Therefore we can conclude that the proportion  is 189 / 25.

The linear function which can be used to represent the situation is y = 6.4x + 1900 and airplane weight if it is carrying 60 gallons of fuel is 2,284 pounds

y = mx + b

where,

Now, we can use the two sets of data points given to us to first solve for the slope m as:

m = (2188 - 2060) / (45 - 25)

= 128 / 20

= 6.4

y - yo = m(x - xo)

y - 2060 = 6.4(x - 25)

y - 2060 = 6.4x - 160

y = 6.4x - 160 + 2060

y = 6.4x + 1900

x = 60

So,

y = 6.4x + 1900

y = 6.4(60) + 1900

y = 384 + 1900

y = 2,284 pounds

Therefore, the weight of the airplane if it is carrying 60 gallons of fuel is 2,284 pounds

Answer: 114.

Step-by-step explanation: This would be an equation to set up. We have all three parts of the equation: The sum of the two numbers (236), one of the integers (122), and then an unknown number, (let's call it x).  Since 236 is the total, 122 is one of the numbers, we need to look for the unknown number, x. Then we would set it up as 122+x=236.  Subtract 122 to both sides, to get 114.

To find the arc length we need to know the angle subtended by the arc.

From the diagram we notice that angle MNK is of 180°.

We also notice that:

Then the angle subtended by the arc MKL is 218°.

Now that we know this we need to remember that the arc length is given by:

in this case the radius is 3 ft (The radius is half the diameter) then we have that:

Therefore the arc length is 11.4 ft.

Using it's concept, the probabilities are given as follows:

a) Both go off on schedule: 0.30 = 30%.

b) Both go off on schedule: 0.2 = 20%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

From the text of the problem, the probability of A and not B is of 0.2, that is:

A x (1 - B) = 0.2.

We can multiply the probabilities as the events are independent.

In item a, the probability of neither is of 0.2, hence:

(1 - A) x (1 - B) = 0.2.

From the first equation, we have that:

A = 0.2/(1 - B).

From the second equation, we have that:

(1 - A) = 0.2/(1 - B).

Hence:

A = 1 - A

2A = 1

A = 0.5.

Then we can find B as follows:

(1 - A) x (1 - B) = 0.2.

1 - B = 0.2/0.5

1 - B = 0.4

B = 0.6.

The probability of both is:

A x B = 0.5 x 0.6 = 0.30 = 30%.

For item b, we consider that:

(1 - A) x B = 0.3.

We also have that:

A x (1 - B) = 0.2.

From the first equation:

B = 0.3/(1 - A).

Then, replacing on the second:

A x (1 - 0.3/(1 - A)) = 0.2

Which has a solution of:

A = 0.5, B = 0.4.

Hence the probability of both is:

0.4 x 0.5 = 0.2 = 20%.
