What percent of the lights are on?
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

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.

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]

60^2−802=100260 squared minus 80 squared is equal to 100 squared
80^2−602=100280 squared minus 60 squared is equal to 100 squared
Answer:
2nd option
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
The expression 40x2 – 65x 50 represents the sum of the interior angles of a regular pentagon in degrees. if the interior angles of the pentagon are equal, which expression represents the measure of two angles? 2x2(20 – 32x 25x2) 2(8x2 – 13x 10) 5x2(8x2 – 13x 10) 5(3x2 – 8x 5)
The expression which represents the measure of two interior angles of the provided regular pentagon is 16x²-26x+20.
What is regular Pentagon?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]

Chen is a lorry driver.
He earns a bonus if he drives at least 2.8 kilometres per litre of fuel.
The figures show some information about Chen's last journey.
Journey time 4.5 hours
Average speed 61 km/h
Amount of fuel used 96 litres
Work out whether Chen earned a bonus for this journey.
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
Step-by-step explanation:
Calculating distance travelled by Chen
Journey time x Average speed4.5 hours x 61 km/h274.5 kmCalculating distance covered per litre of fuel
Distance covered / Amount of fuel used274.5 / 962.86 km/litreThe requirement was 2.8 km/litreTherefore, Chen has earned a bonus for this journeyVic's favorite cookie recipe uses 250250250 grams of flour for every 170170170 grams of butter.
