Which of the following best describes the circled part of the
statement?
7x + 9= 40
Answers
Answer:
4(3/7)
Explanation:
7x+9=40
7x=40-9
x=31/7
x=4(3/7)....
The circled part of the statement, "7x + 9," is the algebraic expression on the left side of the equation. This expression represents the sum of the product of 7 and the variable x and the value 9.
What is a mathematical expression?The circled part of the statement, "7x + 9," represents the mathematical expression for the left side of the equation. It is composed of two terms: "7x" and "9." The term "7x" is a product of a coefficient, 7, and a variable, x. This means that the value of "7x" changes depending on the value of x. The term "9" is a constant, which means that its value remains the same regardless of the value of x. Together, these two terms make up the left side of the equation and represent the value that we are trying to find by solving the equation.
The right side of the equation, "40," represents the value that we are trying to match the left side to by solving the equation. The equation is then solved by isolating the variable x, which is done by subtracting 9 from both sides of the equation, which results in 7x = 31, then dividing both sides by 7, which results in x = 4.5.

Can anyone give a paragraph answer to what global footprint means! Thank you.
Answers
Answer:
The ecological footprint is a method promoted by the Global Footprint Network to measure human demand on natural capital, i.e. the quantity of nature it takes to support people or an economy.[2][3][4] It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity, the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on the environment.
Footprint and biocapacity can be compared at the individual, regional, national or global scale. Both footprint and biocapacity change every year with number of people, per person consumption, efficiency of production, and productivity of ecosystems. At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2014, humanity has been using natural capital 1.7 times as fast as Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.7 planet Earths.[1][5]
Ecological footprint analysis is widely used around the world in support of sustainability assessments.[6] It enables people to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations.[2]

4. Patient X is a 32 year old female. She goes to the gym less than 5 times a month. She
recently went to the doctor and it was determined that her kidneys are retaining sodium
causing an increase in blood volume. Use the information provided about this patient to
select the correct blood flow you would expect the patient to have and the correct effect
of that blood flow.
a. High Blood Pressure. Increased Blood Flow
6. High Blood Pressure. Decreased Blood Flow
C Low Blood Pressure increased Blood Flow
Lou Blood Pressure Decreased Blood Flow
Answers
Answer:
b. High Blood Pressure. Decreased Blood Flow
Explanation:
As per the details, patients's kidney is retaining more sodium causing increase in blood volume which will result into high blood pressure and decrease in blood flow.
This is because excessive salt in the body causes high blood pressure (hypertension) that results into stiff and narrow blood vessels and decreases blood flow to other organs. To overcome the supply of less blood to the organs, the heart pump blood with more intensity that further increases blood pressure.
Hence, the correct option is "b".

Are viruses considered living?
Are viruses considered a cell?
What does a virus need in order to
replicate/reproduce?
How do viruses look
Answers
Answer:
In order to replicate, viruses must first hijack the reproductive equipment of a host cell, redirecting it to 'photocopy' the genetic code of the virus and seal it inside a newly formed container, known as the capsid. Without a host cell, the virus simply can't replicate.
What does a virus need in order to
replicate/reproduce?
Explanation:
Viruses replicate in four stages:
1. Attachment
During this stage, the virus attaches itself to the host. It may have either spikes or pins to help it attach.
2. Penetration
The virus injects the nucleic acid into the host cell.
3. Transcription
The host cells nucleic acid disintegrates, and the virus assembles the fragments to create its own structure and its own DNA or RNA.
4. Lysis
The host cell is split open to release the newly copied viruses it created in the host cell.
The new copies of the virus then repeat the process in new host cells.

BLOOD VESSELS:
Blood vessels are a part of the components that make up the circulatory system. They function to convey blood from one location to the other.There are three types of blood vessels namely: veins, arteries and capillaries.
Veins: Veins are vessels that convey deoxygenated blood back to the heart (except pulmonary veins). Veins are characterized by the possession of valves that help prevent the backward flow of blood. Arteries: Arteries are vessels that carry oxygenated blood away from the heart. Capillaries: Capillaries are tiny vessels that connect arteries and veins.

Which one element makes up the majority of your body weight? Which one element makes up the majority of your body weight? carbon water oxygen hydrogen
Answers
Answer:
carbon
Explanation:
The element that makes up the majority of the bodyweight of all living organisms is carbon.
The body of organisms is made up of minerals and molecules of life, otherwise known as organic compounds. The molecules include protein, carbohydrate, lipids, etc. All the molecules are largely made up of carbon together with other elements such as nitrogen, phosphorus, oxygen, and sulfur.
Answer:
oxygen
Explanation:
Your body is mostly water. And water is, by weight, mostly oxygen. (There are two hydrogen atoms for every oxygen atom in water, but one atom of oxygen has much more mass than one atom of hydrogen). That is why, if you weigh 150 pounds, about 100 of those pounds is oxygen.
