Sorry I haven't been answering your questions I'm just behind on homework.

The cost price of the article, which is sold for Rs. 150 at a gain but if sold for Rs. 135 would have resulted in a loss equal to 50% of the original gain, is Rs. 127.50.

The cost price is the difference between the selling price and the profit or gain.

The difference is determined by subtraction.

Selling price of the article = Rs. 150

Loss if sold at Rs. 135 = 50% of the original gain

Original gain = Rs. 15 (Rs. 150 - Rs. 135)

50% of the original gain = Rs. 7.50 (Rs. 15 x 50%)

Cost price of the article = Rs. 127.50 (Rs. 135 - Rs. 7.50)

Thus, the cost price is Rs. 127.50.

The height of the air ballon at 'm' minutes is expressed in the function and the value of h(3)=1600, h(9)=2800,h(11)=3200

We have given a function h in terms of m. Now we have to explain the contextual meaning of each and every expression it contains

1.) h = It is height at which ballon is cruising above from the ground level.

2.) m = It denotes the instance of minute at which we are talking about

3.) h(m) = The height as the function of minute, means the height of the ballon in changing with respect to the minute

4.) 1000 = It is the height at which ballon was cruising earlier and then started ascending

5.)200 = 200 feet the distance covered in a minute while ascending above

6.) 200m = distance ascended for 'm ' minutes

7.) 1000+200m = The total height that balloon covered after ascending for m minutes.

Now,

height at 3 minute = h(3) = 1000+200(3)=1000+600=1600

height at 9 minute = h(9) = 1000+200(9)=1000+1800=2800

height at x minute = h(x) = 1000+200(x)= 3200

1000 + 200x = 3200

200x = 2200

x = 11

Therefore, h(3) = 1600 , h(9)= 2800,h(11)=3200 are the different values of height 'h' at different 'm' minutes.

180－115=65

Answer:

so it will be 75 - 64 = 11 feet above the water.

Answer:

\(\textsf{12)} \quad \text{a.}\;\;m \angle 1 = 107^{\circ}, \quad \text{b.}\;\;m \angle 2 = 107^{\circ}, \quad \text{c.}\;\;m \angle 3 = 73^{\circ}\)

\(\textsf{13)} \quad EC = 6\)

\(\textf{14)}\quad \text{a.}\;\;x = 33, \quad \text{b.}\;\; x = 8\)

Step-by-step explanation:

As the base angles of an isosceles trapezoid are congruent, the measures of angles E and J are the same. Therefore:

\(m\angle 3 = 73^{\circ}\)

The opposite angles of an isosceles trapezoid sum to 180°. Therefore:

\(\implies m\angle 1 + m\angle 3 = 180^{\circ}\)

\(\implies m\angle 1 + 73^{\circ} = 180^{\circ}\)

\(\implies m\angle 1 = 107^{\circ}\)

Since the base angles of an isosceles trapezoid are congruent, the measures of angles A and N are the same. Therefore:

\(m\angle 2 = 107^{\circ}\)

\(\hrulefill\)

The diagonals of isosceles trapezoid ABCD are AC and BD.

Point E is the point of intersection of the diagonals. Therefore:

\(BE + ED = BD\)

\(AE + EC = AC\)

As the diagonals of an isosceles trapezoid are the same length, BD = AC. Therefore:

\(AE + EC = BD\)

Given BD = 20 and AE = 14:

\(\implies AE + EC = BD\)

\(\implies 14 + EC = 20\)

\(\implies 14 + EC - 14 = 20 - 14\)

\(\implies EC = 6\)

The midsegment of a trapezoid is a line segment that connects the midpoints of the two non-parallel sides (legs) of the trapezoid.

The formula for the midsegment of a trapezoid is:

\(\boxed{\begin{minipage}{6 cm}\underline{Midsegment of a trapezoid}\\\\$M=\dfrac{1}{2}(a+b)$\\\\where:\\ \phantom{ww}$\bullet$ $M$ is the midsegment.\\ \phantom{ww}$\bullet$ $a$ and $b$ are the parallel sides.\\\end{minipage}}\)

a)  From inspection of the given trapezoid:

Substitute these values into the midsegment formula and solve for x:

\(x=\dfrac{1}{2}(18+48)\)

\(x=\dfrac{1}{2}(66)\)

\(x=33\)

Therefore, the value of x is 33.

b)  From inspection of the given trapezoid:

Substitute these values into the midsegment formula and solve for x:

\(15=\dfrac{1}{2}(22+x)\)

\(30=22+x\)

\(x=8\)

Therefore, the value of x is 8.

Answer:

160 kilometers per hour

9560 kilometers per minute

Answer:

Speed of the car is equivalent to 159.39 KM/hour or 2.6565 Km/min.

-Step by Step-:

-The speed of the car is given as  99 mi/hour.

Now, WE know that 1 Mile = 1.61 KM

Hence, in order to calculate the speed of the car in KM/hour we will multiply the speed of the car in miles with 1.61.

⇒The speed of the car in KM/hour = 99 × 1.61 KM = 159.39 KM/hour

Also, 1 hour = 60 minutes

⇒ Speed of the car in KM/min = (159.39) ÷ 60 = 2.6565 K/min

The area of the triangle with angle B = 128°, side a = 86, and side c = 37 is approximately 2302.7 square units.

To find the area of a triangle when one angle and two sides are given, we can use the formula for the area of a triangle:

Area = (1/2) * a * b * sin(C),

where a and b are the lengths of the two sides adjacent to the given angle C.

In this case, we have angle B = 128°, side a = 86, and side c = 37. To find side b, we can use the law of cosines:

c² = a² + b² - 2ab * cos(C),

where C is the angle opposite side c. Rearranging the formula, we have:

b² = a² + c² - 2ac * cos(C),

b² = 86² + 37² - 2 * 86 * 37 * cos(128°).

By substituting the given values and calculating, we find b ≈ 63.8.

Now, we can calculate the area using the formula:

Area = (1/2) * a * b * sin(C),

Area = (1/2) * 86 * 63.8 * sin(128°).

By substituting the values and calculating, we find the area of the triangle to be approximately 2302.7 square units.

The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).

To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.

1. Find the derivative of the function:

  y' = 3x² - 6x - 9

2. Set the derivative equal to zero and solve for x:

  3x² - 6x - 9 = 0

3. Factorize the quadratic equation:

  3(x² - 2x - 3) = 0

4. Solve the quadratic equation by factoring or using the quadratic formula:

  (x - 3)(x + 1) = 0

  This gives us two possible values for x: x = 3 and x = -1.

5. Substitute these critical points back into the original function to find the corresponding y-values:

  For x = 3:

  y = (3)³ - 3(3)² - 9(3) + 4

    = 27 - 27 - 27 + 4

    = -23

  For x = -1:

  y = (-1)³ - 3(-1)² - 9(-1) + 4

    = -1 - 3 + 9 + 4

    = 9

6. Therefore, the turning points are (3, -23) and (-1, 9).

Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

Step-by-step explanation:

The correct answer would be D. 64

The 40 percentage of 160 is 64, the correct option is D.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

Total value= 160

Percentage= 40%

Now,

To find 40% of 160,

=40%=0.4

We can multiply 0.4 by 160.

=0.4*160

=64

Therefore, by the given percentage the answer will be 64.
