Michael is building a skateboard ramp He cannot decide how long the ramp should be so he draws the blueprint below. Michael draws a vertical line in the big triangle AAGH to form the AABC Michael determines the slope of both triangles to find out which ramp will be steeper​

Explanation:

The shorter side lengths 3 and 3 add to 3+3 = 6, which is not larger than the remaining side 9. This is why a triangle is not possible.

For a triangle to be possible, we need the sum of any two sides to be larger than the third side. Refer to the triangle inequality theorem.

I recommend making slips of paper that are 3 inches, 3 inches, and 9 inches long (or replace "inches" with "centimeters"). Then try to make a triangle with those slips of paper. You should find such a task is impossible: as mentioned, the 3 inch sides come up short when trying to attach to the 9 inch side.

The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

A triangle cannot be formed with side lengths of 3, 3, and 9.

To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

However, in this case, the sum of the lengths of any two sides is 3+3=6, which is less than the length of the third side, 9.

Therefore, it is not possible to form a triangle with side lengths of 3, 3, and 9.

Thus,

The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.

The number of each type of tickets which August sold is equal to: B. 20 students and 15 adults.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of adult tickets sold and number of student tickets sold, and then translate the word problem into an algebraic equation as follows:

Since Adults pay $7 a ticket while students pay $5 a ticket for a total cost of $205, an algebraic equation to model is given by;

7a + 5s = 205

For the sales of 35 tickets, we have:

a + s = 35      

Solving for a, we have the following:

7a + 5(35 - a) = 205

7a + 175 - 5a = 205

2a = 205 - 175

2a = 30

a = 30/2

a = 15 adult tickets.

For the number of student tickets, we have:

s = 35 - a

s = 35 - 15

s = 20 student tickets.

An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. In mathematics, an expression is a phrase that has at least two numbers or variables and at least one arithmetic operation. Addition, subtraction, multiplication, or division are all examples of math operations. A number, a variable, or a combination of numbers, variables, and operation symbols constitutes an expression. An equation consists of two expressions joined by an equal sign. Example of a word: the sum of 8 and 3. Example of a word: The product of 8 and 3 equals 11. 8 + 3 is an expression.

Here,

Answer:

m is equal to [tex]34\sqrt{2}[/tex]

Step-by-step explanation:

We can use the cosine function to evaluate m.

Note that [tex]m[/tex] is the hypotenuse in this triangle.

[tex]cos(x)=\frac{A}{H}[/tex]

[tex]A[/tex] is the adjacent side

[tex]H[/tex] is the hypotenuse

Lets look at the 60 degree angle.

The side adjacent to it is [tex]17\sqrt{2}[/tex].

Therefore we can say that

[tex]cos(60)=\frac{17\sqrt{2} }{H}[/tex]

Lets solve for [tex]H[/tex].

[tex]cos(60)[/tex] is equal to [tex]\frac{1}{2}[/tex].

[tex]\frac{1}{2} =\frac{17\sqrt{2} }{H}[/tex]

Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.

[tex]1*H=17\sqrt{2}*2\\H=17\sqrt{2}*2\\H=34\sqrt{2}[/tex]

Answer: 5-5x

Step-by-step explanation:

A protractor is used to measure angles in degrees (°). With the aid of a protractor, one may measure and calculate angles in terms of degrees.

Through the use of a protractor, angles are measured in degrees (°). In order to calculate or draw angles in terms of degrees, a protractor is a measuring tool that is utilised. Using a protractor, for instance, we can observe that the black arrow in the image below crosses the 90° line at 100°. Thus, the angle has a 100° measurement.

Generally speaking, supplementary angles are those where the total of two angles is greater than 180 degrees. A supplement to another angle is stated to exist for each of the angles. By deducting an angle's complement from 180 degrees, we can calculate its value.

A 113 degree angle's complement is a 67 degree angle.

Answer:

4) 100

5) 120

Step-by-step explanation:

4) Number of sides in the polygon = n = 6

Sum of all the angles of n-sided polygon = (n -2)* 180

                                                                    = (6 - 2) *180

                                                                    = 4 * 180

                                                                    = 720

x + x + 9 + 90 + 120 +156 + 145 = 720

Combine like terms,

                             2x + 520  = 720

Subtract 520 from both sides,

                                           2x = 720 - 520

                                           2x = 200

Divide both sides by 2,

                                             x = 200÷2

                                             [tex]\sf \boxed{x = 100^\circ}[/tex]

5)    Sum of all the angles of 5 sided polygon = ( 5 - 2)*180

                                                                           = 3 * 180

                                                                            = 540

    x + x + x + x + 60 = 540

                    4x + 60 = 540

                            4x = 540 - 60

                             4x = 480

                               x = 480 ÷ 4

                               [tex]\sf \boxed{x = 120^\circ}[/tex]

Answer:

4.) You need 720 degrees sum for 6 sided polygon.

5.) You need 540 degrees for a 5 sided polygon.

Step-by-step explanation:

4.) -

120 + 156 + 145 + 90= 511

720 - 511 = 209.

209 - 9 = 200

200 / 2 = 100

X is equivalent to 100 Degrees

5.) -

Since X is the same for all sides we'll take 60 from 540 = 480

480 / 4 = 120

X = 120

The volume of the baseball to the nearest cubic inch is 9 cubic inches.

A sphere is a three dimensional figure which consists of set of all the points which are at an equal distance from a point called the center of the sphere.

Volume is the space occupied by a three dimensional object.

Given that,

Radius of a baseball = 1 3/10 inches = (1 × 10 + 3) / 10 = 13/10 inches.

Also we know that,

Volume of a sphere = 4/3 π r³, where r is the radius.

Volume of the baseball = 4/3 π (13/10)³

                                       = 4/3 π (1.3)³

                                       = 4/3 π × 2.197

So, the arc length between each spoke is the circumference of the wheel divided by the number of arcs, which is 1413.8 mm / 24 = 58.91 mm.

Answer: x = 5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7 − 8(x − 3) = x − 14

7 + (−8)(x) + (−8)(−3) = x + − 14 (Distribute)

7+ (−8x) + 24 = x + (−14)

(−8x) + (7+24) = x − 14 (Combine Like Terms)

−8x + 31 = x − 14

−8x + 31 = x − 14

Step 2: Subtract x from both sides.

−8x + 31 − x = x − 14 − x

−9x + 31 = −14

Step 3: Subtract 31 from both sides.

−9x + 31 − 31 = −14 − 31

−9x = −45

Step 4: Divide both sides by -9.

−9x/−9 = −45/−9

The exact length of the given curve is 62/3

We can calculate the above answer by following the steps given below,

We have been given the following values,

x = 1/3 √y (y - 3), 4 ≤ y ≤ 16

The curve is of the length, x = f(y) from y =a to y = b is given by:

x = 1/3 √y (y - 3)

x = 1/3 (- 3)

dx/dy = 1/3 [(3/2)- (3/2)]

= 1/3 [(3/2) - (3/2)]

= 1/2 [ - 1/]

= (y-1)/2√y = f'(y)

Now we will calculate the length of the curve

= [tex]\int\limits^a_b {\sqrt{1+f'(y)^{2} } } \, dy[/tex]

= [tex]\int\limits^a_b{\sqrt{1+ (\frac{y-1}{2\sqrt{y} } )^2} } \, dy[/tex]  (here a= 4, b=16)

= [tex]\int\limits^{16} _4 {\sqrt{1+ (\frac{y^2+2y-1}{4y} } )^} } \, dy[/tex]

= [tex]\int\limits^{16}_4 {\frac{y+1}{2\sqrt{y} } } \, dy[/tex]

= [tex]\int\limits^{16}_4 {\frac{1}{2}\sqrt{y} } \, dy+ \int\limits^{16}_4 {\frac{1}{2\sqrt{y} } } \, dy[/tex]

= [1/3 (64-8)] +[4-2]
