What is the value of xy
2y when x
-3 and y = 6?

Answer:

≈ 9.8

Step-by-step explanation:

Lets use the Pythagorean theorem.

a^2 + b^2 = c^2.

c is the hypotenuse or the longest side of a triangle.

a and b are the other 2 sides.

10^2 + b^2 = 14^2

10^2 + b^2 - 10^2 = 14^2 - 10^2

b^2 = 14^2 - 10^2

b^2 = 196 - 100

b^2 = 96

b ≈ 9.8

The length of the third side would be 9.8 units.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The right triangle is given in the question, as shown.

According to Pythagoras' theorem,

In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

a² + b² = c²

Here c = 14 is the hypotenuse or the longest side of a triangle.

a = 10 and b are the other two sides.

10² + b² = 14²

10² + b² - 10² = 14² - 10²

b² = 14² - 10²

b² = 196 - 100

b² = 96

b ≈ 9.8

Thus, the length of the third side would be 9.8 units.

Answer:

Step-by-step explanation:

The requried, 40 more student tickets than adult tickets were sold.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,

Let x be the number of adult tickets sold
Let y be the number of student tickets sold

We know that the total number of tickets sold is 230, so:

x + y = 230

We also know that the total amount collected from ticket sales is $995, so:

5.5x + 3.5y = 995

To solve for x and y, we can use the first equation to solve for one of the variables in terms of the other, and then substitute that expression into the second equation:

x + y = 230

y = 230 - x

5.5x + 3.5y = 995

5.5x + 3.5(230 - x) = 995

2x = 190

x = 95

So 95 adult tickets were sold. To find the number of student tickets sold, we can substitute this value of x back into the first equation:

x + y = 230

95 + y = 230

y = 135

Therefore, 135 student tickets were sold. To find how many more student tickets than adult tickets were sold, we can subtract the number of adult tickets from the number of student tickets:

135 - 95 = 40

Thus, 40 more student tickets than adult tickets were sold.

Answer:

A= 30

Step-by-step explanation:

This requires several steps.

First, you need to find the 2 other missing angles.

One can be found easily by substracting 130 from 180

so 180-130 = 50

The other angle is the same as 8x+4

Now set up your equation

180=3x-6 + 8x+4 +50

180 = 3x + 8x -6 + 4 +50

180+6-4-50 = 11x

132 = 11x

132/11 = x

12 = x

Now plug in 12 for x in your angle A

A=3x-6

A=3 * 12 - 6

A=36 - 6

A= 30

Answer:

Hello!! answer: a = 45

Step-by-step explanation:

This is a complimentary angle so we will just do 90 - 45 and get 45 because 45 + 45 = 90 Hope that helps!

Answer:

a = 45

Step-by-step explanation:

The total angle of the shape is 90°

That means you should subtract 90° from 45°

90 - 45 = 45

That's your answer!

[tex]143.8\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): [tex]\frac{1}{2}\cdot 4.5^2\cdot \pi[/tex]

Area of trapezoid (average of bases multiplied by height): [tex]16\cdot 7[/tex]

Thus, the total area of the figure is:

[tex]\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}[/tex]
