What value of x would prove a || b (a parallel to b)? (Hint: Add consecutive interior angles to solve for x).

Answers

Answer:

x=8

Step-by-step explanation:

19x-13+6x-7=180

x=8

We have a || b (a parallel to b), the interior angle property. Therefore, the value of x would be 8.

What is the sum of interior angles of parallel lines?

The sum of all the interior angles of parallel lines is equal to 180 degrees.

We have a || b (a parallel to b), the interior angle property

19x - 13 + 6x - 7 = 180

25x - 20 = 180

25x=  200

x = 8

Therefore, the value of x would be 8.

A person playing a game of chance has a 0.20 probability of winning. If that person plays the game 20 times and wins half of that number of times, what is the difference between the theoretical probability and the experimental probability of that person winning?

Answers

Answer:

Step-by-step explanation:

The theoretical result is 0.2 * 20 = 4

The experimental result is 1/2 * 20 = 10

The difference is 10 - 4 = 6

The probability difference = 6/20 = 0.3

A farmer sells 7.5 kilograms of apples and pears at the farmer's market. 3/4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?

Answers

Answer: 1.87 kg of pears

Step-by-step explanation:

7.5 kg of both apples and pears were sold. 3/4 of this 7.5 kg is apples which means the amount of apples sold is:

= 7.5 * 3/4

= 5.63 kg of apples

The amount of pears sold would therefore be:

= Total amount sold - Amount of apples

= 7.5 - 5.63

= 1.87 kg of pears

Please help, nobody is helping I need to find surface area

Answers

Answer:

A) 147.6 sq m

Step-by-step explanation:

Separate the pyramided out into 4 triangles and add those

3 of them (sides) will be the same

[tex]A=h\frac{b}{2} \\A=10\frac{4}{2} \\A=20[/tex]

This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.

The area of all 3 sides together is 40*3 = 120 sq m

For your base, your height will be 6.9 and your base is 4

A = 13.8  sq m

multiply by 2 again for the entire base

A=27.6 sq m

Now add both

120 + 27.6

Answers

Answer:

From greatest to least, the order is:

[tex]3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}[/tex]

Step-by-step explanation:

Given

[tex]Closest\ Benchmark \to Number[/tex]

[tex]3\frac{6}{25} \to 3[/tex]

[tex]3\frac{4}{9} \to 4[/tex]

Required

Order [tex]3\frac{6}{25}, 3.8, 3\frac{4}{9}[/tex] from greatest to least

From the given parameters, we have:

[tex]3\frac{6}{25} \to 3[/tex]

[tex]3\frac{4}{9} \to 4[/tex]

This implies that:

[tex]3\frac{4}{9}\ >\ 3\frac{6}{25}[/tex] --- we know this from the nearest benchmark

Convert [tex]3\frac{4}{9}[/tex] to decimal

[tex]3\frac{4}{9} = 3.44[/tex]

By comparison;

[tex]3.8 >\ 3\frac{4}{9}[/tex]

Hence, the list is:

[tex]3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}[/tex]

Hi there!

I believe your answer is:  

D) {(1, 2), (2,4), (−1, 2), (0,3)}

»»————-　★　————-««  

Here’s why:  

A function is a relation in which one element of the domain is assigned to exactly one element of the range. This means that the domain (x) values must not repeat.

⸻⸻⸻⸻

Option A's answer is incorrect, as the domain value of '5' repeats.

{(5, 0), (0, 1), (5, 2), (4,4)}  

⸻⸻⸻⸻

Option B is not a function due to the repeating '-4' value.

{(0, 1), (−4, 1), (4, 2), (−4,−1)}

⸻⸻⸻⸻

The '3' in option C's given relation repeats.

{(3, 2), (2,1), (−1, 2), (3,3)}

⸻⸻⸻⸻

Option D is the correct answer, as there are no domain values that repeat.  

{(1, 2), (2,4), (−1, 2), (0,3)}

Therefore, option D is a function.

Jess is building a skateboarding ramp in the shape of a triangular prism with the dimensions shown. If Jess wants to cover all faces of the ramp with plywood, how much plywood will he need? A triangular prism. The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet. The 2 triangular sides have a base of 3 feet and height of 4 feet.

Answers

Answer:

156 ft²

Step-by-step explanation:

Given :

The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet.

The 2 triangular sides have a base of 3 feet and height of 4 feet

We sum the area of each side:

Area of triangular side = 1/2 * base * height

Since there are 2 triangular sides :

Total area of triangular side = 2(1/2 * base * height)

Triangular side = 2 * 1/2 * 3 * 4 = 12 feet²

Area of rectangle sides = lengtb * width

Area 1 = 12 * 3 = 36 ft²

Area 2 = 12 * 5 = 60 ft²

Area 3 = 12 * 4 = 48 ft²

Total = 12 + 36 + 60 + 48 = 156 ft²
