Step-by-step explanation:

using the converse of Pyhagoras' identity

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 100 , then 100² = 10000

60² + 80² = 3600 + 6400 = 10000

then

60² + 80² = 100²

thus the triangle is right

Answer:

Yes, Chen earned a bonus for the journey.

Step-by-step explanation:

1 hour = 61 km

4.5 hrs = 61 * 4.5 = 274.5 km

Now,

96 litres = 274.5 km

1 litre = 274.5/96 km

1 litre = 2.859 = 2.9 km (approximately)

So, he drived more than 2.8 kilometers per litre of fuel.

Answer:

Yes

Answer: 3) [tex]\frac{x+3}{x}[/tex]

Step-by-step explanation:

Start by factoring the numerator by grouping

[tex]\frac{x^3+2x^2-9x-18}{x^3-x^2-6x} \\\frac{(x^3+2x^2)+(-9x-18)}{x^3-x^2-6x} \\\frac{x^2(x+2)-9(x+2)}{x^3-x^2-6x} \\\frac{(x^2-9)(x+2)}{x^3-x^2-6x} \\\frac{(x-3)(x+3)(x+2)}{x^3-x^2-6x}[/tex]

Now factor the denominator

[tex]\\\frac{(x-3)(x+3)(x+2)}{x^3-x^2-6x}\\ \\\frac{(x-3)(x+3)(x+2)}{x(x^2-x-6)}\\[/tex]

Factor the trinomials by finding two numbers that add to get -1 and multiply to get -6. In this case the numbers are -3 and 2

[tex]\\\frac{(x-3)(x+3)(x+2)}{x(x^2-x-6)}\\\\\\\frac{(x-3)(x+3)(x+2)}{x(x-3)(x+2)}\\[/tex]

Cancel out the terms that are both in the numerator and denominator. In this case they are (x-3) and (x+2)

[tex]\\\frac{(x-3)(x+3)(x+2)}{x(x-3)(x+2)}\\\\\\\frac{(x+3)}{x}\\[/tex]

Answer:

Step-by-step explanation:

The probability of picking a number beween 2 and 7 from the numbers placed in the bag is 2/5.

Probability is a statistial measure used to determine the chances that a given event would happen. If the event would happen with certainity, it would have a value of 1. If it is certain the event would not happen, it would have a value of 0.

The probability of picking a number beween 2 and 7 = numbers between 2 and 7 / total numbers in the bag

Givens

pi = 3.14

r = 10 inches

C = ?

Solution

C = 2*pi * r             Put the givens into the formula

C = 2* 3.14 * 10   Combine

C = 6.28 * 10

C = 62.8 inches.

Step-by-step explanation:

I personally think that the answer here would be C, all the birds in the forest.

The first 25 birds that were recorded are not the population.

The species with the greatest number is not the population. It is the most thriving species.

The species that are native to the area don't make up the whole population. They make up part of it, not the whole of it.

I hope this makes sense and it helps.

The expression which represents the measure of two interior  angles of the provided regular pentagon is 16x²-26x+20.

Regular Pentagon is the closed shaped polygon which has 5 sides equal in measure and 5 interior angles equal in measure.

The expression, which angles represent the sum of the interior angles of a regular pentagon in degrees, is,

[tex]40x^2 - 65x +50[/tex]

The interior angles of the given pentagon are equal. A Pentagon has 5 sides. Thus, the measure of angle of interior angle of the regular pentagon is,

[tex]m\angle n=\dfrac{40x^2 - 65x +50}{5}\\m\angle n=\dfrac{5(8x^2 - 13x +10)}{5}\\m\angle n=8x^2-13x+10[/tex]

The measure of two angles is,

[tex]2m\angle n=2(8x^2-13x+10)\\2m\angle n=16x^2-26x+20[/tex]

Hence, the expression which represents the measure of two interior  angles of the provided regular pentagon is 16x²-26x+20.

Given the information in the question, in three years, the age of Alica would be  53.

A fraction is a non-integer. It is made up of numerators and denominators. An improper fraction is a fraction where the numerator is larger than the denominator. An example is 5/2/

The first step is to determine Jessica's age in 5 years : 17 + 5 = 22

The second step is to determine Alica's age in 5 years : 5/2 x 22 = 55

Now, subtract 2 from 55: 55 - 2 = 53

Answer:

48% of the lights are on.

Step-by-step explanation:

First, gather the total amount of lights by adding the on and off lights.

72 + 78 = 150

There are 150 total lights.

Now set up a fraction to determine the percentage.

lights on/total lights = 72/150

Divide 72 by 150.

72/150 = 0.48

Multiply this by 100 to get the percent.

0.48 * 100 = 48%

48 percent of the lights are on.

Answer:

48 percent
