the number of two digit is equal to four times the sum of digits. if the product of digits is 8 .find the number.​

Answers

Answer 1

Answer:

I think you are only intended to find

24

Explanation:

10x + y = 4(x + y)                         Remove the brackets

10x + y = 4x + 4y                         Subtract 4x from both sides

10x - 4x + y = 4x - 4x + 4y          Combine like terms

6x + y = 4y                                  Subtract y from both sides

6x + y - y = 4y - y                        Combine

6x = 3y                                        Divide by 3

6x/3 = 3y/3

2x = y

Put this result in the equation below

x*y = 8

x(2x) = 8

2x^2 = 8                                      Divide by 2

2x^2/2 = 8/2

x^2 = 4                                         Take the square root.

√x^2 = √4

x = ± 2

y = 2*x = ±4

Answer

The plus answer for x and y is the one we'll see about first.

10x + y = 20 + 4 = 24

24 =? 4(2 + 4)

24 =? 4*6 = 24

The product of it's digits = 2 * 4 = 8.

24 is definitely one answer.

========================

What about -2 and - 4

-24 = 4(-2 + -4)

-24 = 4*-6 = -24

That works as well

The number of valence electrons an element has changes often, so we cannot use the periodic table to predict the number of valence electrons an element
has
True
False

Answers

Answer:

False

Explanation:

The number of valence electrons on an element is also the same or else it would be a different element.

The statement that the periodic table cannot be used to predict the number of valence electrons  is: FALSE

The number of valence electrons an element has will always remain the same for the element to remain the same element, elese the element will changes with a change in valence electrons.  therefore we can use the periodic table to predict the number of valence electrons that an element has.

A valence electron is an electron that is located in the outermost shell of an  atom or element. It is negative and it is used for the formation of bonds between atoms or elements.

Hence we can conclude that The statement that the periodic table cannot be used to predict the number of valence electrons  is: FALSE .

Jasmine is a healthy girl who is playing outside. Her internal body temperature rises to 38 degrees Celsius, which is above normal. How does her body most likely respond to help her return to homeostasis?

Answers

Answer:

See the answer below

Explanation:

Jasmine's body would help her return to homeostasis by using the negative feedback loop.

The negative feedback loop works to negate the process or processes that lead to the body's setpoint being breached. The setpoint refers to the normal range of operation of body processes such as temperature, pressure, etc.

The skin of Jasmine acts as a sensor and sends information to the control center, the brain. The brain reads the temperature data, finds out that the setpoint has been exceeded, and sends information to the effectors to initiate processes that will return Jasmine's body temperature to normal.

One of the effectors, the blood vessels that supply blood to the skin becomes dilated. Consequently, more blood is supplied to the skin and more heat is lost from the skin due to radiation - blood being a conductor of heat in the body. Another effector, the sweat glands, release sweat to the skin. The evaporation of sweat from the surface of the skin causes the body to cool down. These processes work synergistically to return the body temperature of Jasmine back to homeostasis.

What characteristic of water helps in regulating cell temperature and maintaining homeostasis?

Someone please help i need a claim, evidence, then a reasoning !

Answers

Answer:

The characteristic of water that helps regulate the temperature of the cells and maintain homeostasis is specific heat (Claim).

Explanation:

Specific heat is a physical property that is defined as the amount of heat needed to raise one gram of a substance by one degree Celsius. In the case of water, its specific heat is higher than that of other substances, being its value 4.186 joules/gram °C, or also 1 calorie/gram °C.

- Claim: The property of water that allows cells to regulate temperature and maintain homeostasis is specific heat.

- Evidence: a high specific heat value of water means that in bodies that possess this molecule in large quantities it is more difficult to raise the temperature

- Reasoning: Living beings are formed mostly by a high percentage of water, much of it in the intracellular compartment. The specific high heat of the water makes it difficult to have sudden changes in the internal temperature, even when the environmental temperature is high, which is a property of water that allows thermoregulation and maintains the balance or homeostasis.

If someone stole your DNA, could they steal your identity?

Yes

Criminals might steal DNA to use the genetic identity of their victim

Answer:

yes and no

Explanation:

if someone actually stole your DNA you wouldn't be alive right now,

but if someone stole "parts" of your DNA you would still be the same person because it doesn't matter what you look like you are your own person an example of this are identical twins, identical twins share the same exact DNA but they aren't the exact same person since they both can like different stuff and have different personalities. but if you mean in a biological stand point "if someone stole your DNA, could they steal your identity" of course not, at least not with our technology.

Demand of oxygen in water does not increase with increase in

a/concentration of solid waste
b/number of aquatic plants
c/number of aquatic animals
d/rapid flow of water​

Answers

Answer:

b. number of aquatic plants

Explanation:

The number of aquatic plants doesn't increase the demand for oxygen in water because these plants take in carbon dioxide rather than oxygen. This means that an increase in their number will not trigger an increase demand for oxygen, rather it will trigger an increase demand for carbon dioxide in its dissolved form.

An increase in the concentration of solid waste, increases the demand for oxygen because it is needed for decomposition.

An increase in aquatic animals will increase the demand for oxygen in its dissolved form because aquatic animals take in oxygen to survive.

An increase in the flow of water increases the demand for oxygen because as water flows, it mixes with air. The more rapid it is, the higher the chance to mix with oxygen.

explain how the microscopic fixation of nitrogen can have such a large impact on life?

Answers

because nitrogen is required to biosynthesize basic building blocks of plants, animals, and other life forms. it is found in everything we eat, drink, and even breathe.

The N2 must be changed through a procedure known as nitrogen fixation. Fixation transforms atmospheric nitrogen into forms that plants' root systems can absorb.

What is nitrogen fixation?

Nitrogen fixation is defined as a chemical process that turns airborne molecular nitrogen, which has a powerful triple covalent bond, into ammonia or other related nitrogenous chemicals, usually in aquatic or soil systems but also in industry. In order to give plants access to a vital nutrient that they are unable to naturally obtain from the air, nitrogen-fixing bacteria are used.

Since plants and animals cannot directly utilize atmospheric nitrogen, this mechanism is crucial. Although N2 gas makes up 78% of the atmosphere, most organisms cannot utilize it directly since it must first be transformed into another form. It is transformed into ammonium (NH4+) by bacteria, which plants can subsequently absorb.

Thus, the N2 must be changed through a procedure known as nitrogen fixation. Fixation transforms atmospheric nitrogen into forms that plants' root systems can absorb.

As thermal energy is added to a substance, which of the following changes can be predicted?
O
Spacing between particles will decrease
Vibration of individual particles will increase
Temperature of the substance will decrease
The pressure of the air around the substance will increase

Answers

Answer:

Vibration of individual particle will increase

Explanation:

This is due to the fact that whenever any substance of matter is increased in temperature, the atoms begins to move away from each other. Take for instance an ice cube for example, when an ice cube (a solid) is heated it becomes water, (a liquid). Proving that when a substance is heated, no matter the density of the material, the individual particles, or atoms, begins to spread apart.

Nitrogen is required for protein formation. What is responsible for the bulk of nitrogen fixation?
A.
air

B.
animals

C.
bacteria

D.
lightning

Answers

Answer:

The factor with the responsibility for nitrogen fixation is bacteria (option C).

Explanation:

The nitrogen that contributes to the formation of proteins comes from plants. Due to the inorganic nature of nitrogen, plants require bacteria to contribute to the assimilation of this element, a process called biological nitrogen fixation.

Nitrogen fixing bacteria in plants are called diazotroph and, in some cases, establish a symbiosis with the plant's roots, the rhizobia.

The other options, air, animals and lightning, do not correspond to biological nitrogen fixers with the ability to incorporate nitrogen into plants.
