Camera I (camera I is across from the longest side: 150 ft)

Step-by-step explanation:

You can determine the median of a triangle by looking out for the point that is 2/3 of the distance tht connects from the vertices, to midpoint and oposite sides.

The perpendicular bisector is determined by measuring the point that is equidistant from the segment.

The altitude of a triangle can be found by measiring the height of the triangle's extension that could be inside or outside the triangle. In obtsue triangles, this altitude is commonly found outside the triangle.

Also, the angle bisector of a triangle is the point that is equidistant from the angles sides. These descriptions can help in analyzing a trinagle.

Step-by-step explanation:

Answer:

1st: 56, 2nd: 12, 3rd: 112

Step-by-step explanation:

Let's allow "x" to represent the first angle. This would mean:

1st: x

2nd: x-44 [ The second is 44 less than the first(x) ]

3rd: 2x [ The third is double the first(x) ]

Then, we create and equation using each of these expressions, and set it equal to 180. This is because the sum off all the angles in a triangle is equivalent to 180.

x + x - 44 + 2x = 180

4x = 180 + 44 (224)

4x/4 = 224/4

x = 56

Finally, we insert the value of x into the expressions we made in the beginning.

1st: 56

2nd: 12

3rd: 112

To check our work, we simply need to verify whether this equation is true:

56+12+112=180

This equation is valid. Therefore, the answers provided are correct.

Answer:

The cost to buy 100 shares in ODX group Inc and 300 shares   peer Comms Lts is  

         \(C = \$ 775\)

Step-by-step explanation:

   From the chat we that the cost of 100  ODX shares is  \(\$175\)

    The cost of 100 peer Comms Lts  is  \(\$ 200\)

Hence the cost 300 peer Comms Lts  is  \(k = 3 * 200 = \$ 600\)

Now  the cost of  100 shares in ODX group Inc and 300 shares of  peer Comms Lts  is mathematically evaluated as

           \(C = 175 + 600\)

           \(C = \$ 775\)

The cost to buy 100 shares in ODX group Inc and 300 shares in peer comm LTD is $775.

Given in question the graph here is missing.

We have to calculate the total cost of 100 shares in ODX group Inc and 300 shares in peer comms limited in year 5.

From the graph it is clear that, the x axis shows the no. of year and y axis shows the cost of 100 shares for each type.

From graph, the cost of 100 shares of ODX group in year 5 is $175.

And the cost of 100 shares of peer comm Ltd in year 5 is $ 200.

So the total cost of 300 shares of  peer comm Ltd in 5 year is $(\(200\times3\)) or $600.

Now final cost of 100 shares in ODX group Inc and 300 share in peer comm Ltd is \(($600+$175)\) dollars.

Hence the cost to buy 100 shares in ODX group Inc and 300 shares in peer comm LTD is $775.

Answer:

(a) Bako is 10 years old

(b) His mother was 30 years old when Bako was 5

(c) Bako will be 25 years old when his mother is 50

(d) Bako's mother was 25 years old when he was born

(e) The difference between Bako's age & his mother's is 25 years

Step-by-step explanation:

Let Bako's age five years ago be x years

Presently, Bako is 2x years old (according to the 1st statement)

Normal, Bako's present age should have been (x + 5) years; since he was x years old 5 years ago.

This simply means that Bako's present age is BOTH 2x years & (x + 5) years.

We have to equate them since they mean the same thing (Bako's present age)

x + 5 = 2x

2x - x = 5

Therefore x = 5 years

Remember that x signified Bako's age five years ago... This simply means that Bako's age five years ago was 5 years.

This simply means that Bako's age now is 10 years old.

His mother was then six times 5 years = 30 years old (from the 2nd statement).

If Bako was 5 years old five years ago and his mother was 30 years old... It simply means that Bako was born ten years ago when his mother was 25 years old.

This simply means that Bako's mother is older than him with 25 years.

Therefore, Bako will be 25 years old when his mother is 50 years old

The number of liters of water needed is 471.24 L.

Explanation:

The problem involves finding the amount of water needed to fill a cylinder with a radius of 50 cm and a height of 60 cm. The volume of the cylinder is given by the formula V = πr^2h, where V is the volume, r is the radius, and h is the height. The problem also provides information about a metal sphere with a radius of 18 cm and a volume of 24430 cm^3. However, this information is not directly relevant to finding the volume of water needed.

To solve the problem, we first need to calculate the volume of the cylinder that is filled with water. The height of the water is given as 60 cm, and the radius of the cylinder is given as 50 cm. We can substitute these values into the formula for the volume of a cylinder to find the volume of water needed.

Once we have the volume of water in cubic centimeters, we can convert it to liters by dividing by 1000. This gives us the final answer in liters.

Solving:

The volume of the water needed can be calculated by finding the volume of the cylinder that is filled with water, which is given by the formula:

V = πr^2h

where V is the volume of the cylinder, r is the radius of the cylinder, and h is the height of the water.

Substituting the given values, we have:

V = π(50 cm)^2(60 cm)

V = 471,238.9 cm^3

Since 1 liter is equal to 1000 cm^3, we can convert the volume of water to liters by dividing by 1000:

471,238.9 cm^3 ÷ 1000 cm^3/L = 471.24 L

Therefore, the number of liters of water needed is 471.24 L.

\(EF = 18\)

Step-by-step explanation:

Given

\(\triangle DE\ F\) similar to \(\triangle JHI\)

Required

Find \(EF\)

\(\triangle DE\ F\) similar to \(\triangle JHI\) implies that:

The corresponding sides are:

\(DE \to JH\)

\(DF \to JI\)

\(EF \to HI\)

\(FG \to IK\)

First, solve for x using the following corresponding ratios

\(EF : HI = FG : IK\)

This gives:

\(x + 8 : 3x - 2 = 9 : 14\)

Express as fraction

\(\frac{x + 8 }{ 3x - 2} = \frac{9 }{ 14}\)

Cross multiply

\(14(x + 8) = 9(3x - 2)\)

Open brackets

\(14x + 112 = 27x - 18\)

Collect like terms

\(27x - 14x = 112 + 18\)

\(13x = 130\)

Solve for x

\(x = 10\)

In the diagram, we have:

\(EF = x +8\)

\(EF = 10 +8\)

\(EF = 18\)

∠ GJK = 102°

Step-by-step explanation:

(2x + 92) and (3x + 63) are same- side interior angles and sum to 180° , so

2x + 92 + 3x + 63 = 180

5x + 155 = 180 ( subtract 155 from both sides )

5x = 25 ( divide both sides by 5 )

x = 5

Then

∠ GJK = 2x + 92 = 2(5) + 92 = 10 + 92 = 102°

The measure of angle mKLM is 31.5°.

The angle mKLM can be found using the property of inscribed angle. An inscribed angle is an angle formed by two chords that intersect inside of a circle. The measure of an inscribed angle is half of the measure of its intercepted arc. In this case, the measure of the intercepted arc is the angle mKNM, which is 63°. Therefore, the measure of the inscribed angle mKLM is half of 63°, which is 31.5°.

Formula:

mKLM = 1/2 (mKNM)

mKLM = 1/2 (63°)

= 31.5°

mKLM = 31.5°

Answer: -124/9 or -13.778

Step-explanation: You may not have any idea how to approach this problem but I can help. We are given some information about a number and asked to find out what number it is. Since we don't know what the number is, we can say that it is X (a variable).

If you double X and add 28 you get 4/9. Doubling X can be represented as 2X. If we add 28 to that, we get 2X+28. We are told we get 4/9 which means that 2X + 28 is equal to 4/9 or 2x + 28 = 4/9.

We have now built an algebraic equation for X. We can now simply solve for X.

2X + 28 = 4/9

2X + 252/9 = 4/9   Rewrite 28 as 252/9 so we have common denominators

2X = -248/9            Subtract 252/9 from both sides

X = -124/9               Divide by 2 on both sides and we get X
