Two scientists are measuring lava temperatures. One scientist records temperature of 1725 degrees Fahrenheit. The other scientist records a temperature of 950 degrees Celsius. Which is the greatest temperature? (Use C= 5/9(F - 32)
Final answer:
To compare temperatures, convert them to the same unit. In this case, 1725°F is the greatest temperature between 1725°F and 1742°F.
Explanation:
Converting temperatures: To compare temperatures, we must convert them to the same unit. The first scientist recorded 1725°F, and the second scientist recorded 950°C. Converting 950°C to Fahrenheit, we get 1742°F. Therefore, 1725°F is the greatest temperature.
List the hierarchy of organization in a snowy owl.
The hierarchy of biological organization in a snowy owl involves various nested levels from the most inclusive, the biosphere, to the least complex, atoms. Each level, from biomes to molecules, represents a stage of increasingly specific categorization.
Hierarchy of Biological Organization in a Snowy Owl
The hierarchy of biological organization describes the levels of biological world organization from the most inclusive to the least complex levels. When considering a snowy owl or any other organism, this involves the following hierarchy:
Biosphere - The global ecological system integrating all living beings and their relationships.
Biome - A large community of plants and animals that occupies a distinct region such as tundra where snowy owls may be found.
Ecosystem - The community of living organisms in conjunction with the nonliving components of their environment interacting as a system.
Community - An assembly of different species within a defined area.
Population - A group of individuals of the same species that live in the same area.
Organism - An individual living entity such as a single snowy owl.
Organ Systems - A group of organs that work together to accomplish specific functions.
Organs - Composed of tissues that perform a specific function or group of functions.
Tissues - An ensemble of similar cells from the same origin that carry out a specific function.
Cells - The smallest unit of life.
Organelles - A subunit within a cell that has a specialized function.
Molecules - A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
Atoms - The smallest unit of a chemical element.
The snowy owl, as an organism, falls into this hierarchy at the organism level, but is also part of each of these nested levels up to the biosphere.

What is a positive solution of given equation?
When we find the solution of the equation, we find the values of the variables for which the given equation is correct. Sometimes the values of the solutions comes out negative and sometimes positive and sometimes both or can be 0 too.
To find positive solutions, we only consider those solutions which are positive.
Simplification of the given equation[tex]0 = \dfrac{1}{3}x^2 - 3\\ \\ \text{Adding 3 on both sides}\\ \\ 3 = \dfrac{1}{3}x^2\\ \\ \text{Multiplying 3 on both sides}\\\\ 9 = x^2\\ \\\\ \text{taking square root}\\ 3 = \pm x\\ x = \mp 3 \\ (x = 3), (x = -3)[/tex]

Two containers, A and b begin with equal volumes of liquid. 120 mL is then poured from a to B. Container b now contains four times as much liquid as A. Find the volume of liquid left in container a at the end
The volume of liquid left in container a at the end is 80 mL.
Let's denote the initial volume of each container as ( V ) mL. After pouring 120 mL from A to B, the volume of liquid in A decreases to ( V - 120 ) mL and the volume in B increases to ( V + 120 ) mL.
We're given that after this transfer, the volume in B is four times the volume in A:
[tex]\[ V + 120 = 4(V - 120) \][/tex]
Now, we solve for ( V ):
V + 120 = 4V - 480
120 + 480 = 4V - V
600 = 3V
V = [tex]\frac{600}{3}[/tex] = 200
So, the initial volume in each container was 200 mL. After pouring, A has ( 200 - 120 = 80 ) mL left.

wade purchased 3 videos and one music CD, the CD cost wade $12.99 if he paid the same amount of each video and spent a total of $42.96,how much did each video cost?
Final answer:
To find the cost of each video, subtract the cost of the CD from the total amount spent, and then divide by the number of videos. Each video cost Wade $9.99.
Explanation:
The student's question involves a basic algebra problem where Wade purchased 3 videos and one music CD. The cost of the music CD was $12.99, and the total spent was $42.96. We need to determine how much each video cost.
Firstly, subtract the cost of the music CD from the total spent to find the total cost of the videos:
$42.96 - $12.99 = $29.97.
This means the total cost for the 3 videos is $29.97. Since Wade paid the same amount for each video, we divide the total cost of the videos by the number of videos:
$29.97 ÷ 3 videos = $9.99 per video.
Therefore, each video cost Wade $9.99.
