Based on the calculations, the distance between the garden and the woods is equal to 383 meters.

First of all, we would assign a variable to the different speeds of the turtle and hedgehog as follows:

Mathematically, distance is given by this formula:

Distance = speed × time

Translating the word problem into an algebraic expression, we have;

If they both meet in 5 hours:

D = (S₁ + S₂) × 5  

D = 5S₁ + 5S₂      ......equation 1.

Turtle's speed is 10 meters per hour slower than the hedgehog:

S₁ = S₂ - 10    .....equation 2.

If the turtle had left home 4.5 hours earlier than the hedgehog had left his home:

9.5S₁ + 5S₂ = D + 150    .....equation 3.

Substituting enq. 2 into eqn. 1, we have:

D = 5(S₂ - 10) + 5S₂

D = 5S₂ - 50 + 5S₂

D = 10S₂ - 50      .....equation 4.

Equating eqn. 3 and eqn. 4, we have:

10S₂ - 50 = 9.5(S₂ - 10) + 5S₂ - 150

10S₂ - 50 = 9.5S₂ - 95 + 5S₂ - 150

10S₂ - 50 = 14.5S₂ - 245

14.5S₂ - 10S₂ = 245 - 50

4.5S₂ = 195

S₂ = 195/4.5

S₂ = 43.3 m/h.

Now, we can find the distnace:

D = 10S₂ - 50

D = 10(43.3) - 50

D = 433 - 50

D = 383 meters.

Using the z-distribution, as we have the population standard deviation, it is found that a sample of 96 people must be taken.

It is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

Additionally, we have that [tex]\sigma = 38, M = 10[/tex], hence we solve for n to find the minimum sample size needed.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 2.575\frac{38}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 38 \times 2.575[/tex]

[tex]\sqrt{n} = 3.8 \times 2.575[/tex]

[tex](\sqrt{n})^2 = (3.8 \times 2.575)^2[/tex]

n = 95.7

The profit to the company will be maximum that means pear company should produce 11000 phones for the maximum profit.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Function representing the cost to the manufacturer is,

C(x) = -20x²+ 48000x + 19351

A function that represents the revenue generated is,

R(x) = -23x² + 114000x

Function representing profit to the company,

Profit = Revenue generated - Cost price

        = -23x² + 114000x - ( -20x²+ 48000x + 19351)

        = -23x² + 20x² + 114000x - 48000x - 19351

P(x)  = -3x² + 66000x - 19351

Since this function is a quadratic function, the maximum price generated would be x = -b/2a

From the given quadratic function, a = (-3), b = 66000 and c = -19351

x = - 66000/ 2(-3)

x = -66000/-6

x = 11000

x = 11000 the profit to the company will be maximum.

That means pear company should produce 11000 phones for the maximum profit.

Step-by-step explanation:

Answer:

s = 10

Step-by-step explanation:

This Triangle is a Right Triangle with two equal sides ( because there are two equal angles )

Pytha. Theorem

A² + B² = C²

since we have two equal sides the A = B = s

then

s² + s² = c²

2s² = c²

2s² = (10sqrt2)²

2s² = 100 x 2

2s² = 200

s² = 200/2 = 100

s = sqrt ( 100 )

s = 10

Farmer Brown had 25 cows and chickens. They had a total of 72 legs. How many cows and how many chickens did Farmer Brown have?

Let the number of cows be "x" and the number of chickens be "y".

According to question,

x + y = 25 4x + 2y = 72 -->(ii)

=> 4(x + y) = 25 × 4

=> 4x + 4y = 100 -->(i)

By Elimination method,

Equation (i) - (ii)

(4x + 4y) - (4x + 2y) = 100 - 72

=> 4x + 4y - 4x - 2y = 28

=> 2y = 28

=> y = 28/2

=> y = 14

Putting the value of "y" in Equation (ii)

4x + 2y = 72

=> 4x + 2 × 14 = 72

=> 4x + 28 = 72

=> 4x = 72 - 28

=> 4x = 44

=> x = 44/4

=> x = 11

Total number of cows = 11

Total number of chickens = 14

Note: In the second equation of this question I've taken 4 and 2.

The reason behind it is simple. Since, I've assumed the number of cows is "x" and a cow has four legs that why infront of "x" I've put 4.

And a chicken has 2 legs and I've assumed it as "y" therefore infront of "y" I've put 2.

Farmer Brown had 28 cows and chickens. They had a total of 96 legs. How many cows and how many chickens did Farmer Brown have?

Let the number of cows be "x" and the number of chickens be "y".

According to question,

x + y = 28 4x + 2y = 96 -->(ii)

=> 4(x + y) = 28 × 4

=> 4x + 4y = 112 -->(i)

By Elimination method,

Equation (i) - (ii)

(4x + 4y) - (4x + 2y) = 112 - 96

=> 4x + 4y - 4x - 2y = 16

=> 2y = 16

=> y = 16/2

=> y = 8

Putting the value of "y" in Equation (ii)

4x + 2y = 96

=> 4x + 2 × 8 = 96

=> 4x + 16 = 96

=> 4x = 96 - 16

=> 4x = 80

=> x = 80/4

=> x = 20

Total number of cows = 20

Total number of chickens = 8

Note: In the second equation of this question I've taken 4 and 2.

The reason behind it is simple. Since, I've assumed the number of cows is "x" and a cow has four legs that why infront of "x" I've put 4.

Answer:

144

Step-by-step explanation:

Required area= Area of rectangle +2×(Area of Triangle)

=(10×8)+2×(1/2×8×8)

=80+64=144 in²

Answer:

144 in²

Step-by-step explanation:

To solve for the area of a trapezoid divided into a parallelogram (in this case a rectangle) and two triangles, you calculate the area of each part and add it together.

the area of a triangle = (base • height) / 2

the area of a parallelogram = (base • height)

so:

1. Calculate area of first triangle. 8 • 8 = 64, 64/2 is 32

2. Calculate the area of the second triangle. Since in this situation you have two equal triangles, you multiply the answer to the first part by 2 and get 64 in² again.

3. Calculate the area of the rectangle. 8 • 10 = 80 in²

4. Add the two numbers together. 80 + 64 = 144 in²

Answer:

Step-by-step explanation:

Use the slope formula.

[tex]\underline{\text{SLOPE FORMULA:}}[/tex]

[tex]\longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1} }[/tex]

y2=3

y1=(-9)

x2=1

x1=8

Rewrite the problem down.

[tex]\sf{\dfrac{3-(-9)}{1-8}=\dfrac{3+9}{1-8}=\dfrac{12}{-7}=\boxed{\sf{-\dfrac{12}{7} }}[/tex]

I hope this helps, let me know if you have any questions.

Answer:

[tex]\boxed{\text{Slope} = -\huge\text{(}\dfrac{12}{7}\huge\text{)}}[/tex]

Step-by-step explanation:

Slope formula:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run}}} = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Using the coordinates (8, -9) and (1, 3), we obtain the following:

Substitute the coordinates of both the points in the slope formula to obtain the fraction that represents the slope.

[tex]\implies \text{Slope} = \dfrac{3 - (- 9)}{1 - 8}[/tex]

To obtain a specific fraction or whole number that represents the slope, we need to simplify the numerator and the denominator.

[tex]\implies \text{Slope} = \dfrac{3 + 9}{-7}[/tex]

[tex]\implies \text{Slope} = \dfrac{12}{-7}[/tex]

Use parenthesis and take out the "negative sign" from the denominator.

[tex]\implies \boxed{\text{Slope} = -\huge\text{(}\dfrac{12}{7}\huge\text{)}}[/tex]

Answer:

Explanation:

Formula to calculate the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Therefore, length of CD having coordinates C(3,1) and D(3, 3),

[tex]CD=\sqrt{(3-3)^2+(1-3)^2}[/tex]

[tex]=2[/tex] [tex]units[/tex]

Formula to find the midpoint of CD is,

[tex]M=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}[/tex]

   [tex]=(\frac{3+3}{2},\frac{1+3}{2})[/tex]

   [tex]=(3,2)[/tex]

Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.

Answer:

B) 55, 68,81

Step-by-step explanation:

42-29=13

29-16= 13

So 42 + 13= 55

55+ 13= 68

68+ 13= 81

Answer:

B)  55, 68, 81

Step-by-step explanation:

Given sequence:  3, 16, 29, 42

To determine if the sequence is arithmetic or geometric, work out the difference in the terms.

[tex]\sf 3 \underset{+13}{\longrightarrow} 16 \underset{+13}{\longrightarrow} 29 \underset{+13}{\longrightarrow} 42[/tex]

This sequence adds 13 each time, so as the common difference is constant, it is an arithmetic sequence.  To find the next term in the sequence, simply add 13 to the last term:

42 + 13 = 55

55 + 13 = 68

68 + 13 = 81

Therefore, the next three terms in the given sequence are 55, 68, 81

To solve this using the general form of an arithmetic sequence:

[tex]a_n=a+(n-1)d[/tex]

where:

Given:

[tex]\begin{aligned}\implies a_n & =3+(n-1)13\\ & = 3+13n-13\\ & = 13n-10\end{aligned}[/tex]

Therefore, the next 3 terms in the sequence are:

[tex]\implies a_5=13(5)-10=55[/tex]

[tex]\implies a_6=13(6)-10=68[/tex]

[tex]\implies a_7=13(7)-10=81[/tex]
