Answers

heterogeneous, because it does not have a uniform texture

hope That helps

Answer:

Heterogenous, I just took the quiz

Explanation:

given: f(x) 3x-1. g(x) 2x^2-3
=(3x-1) + (2x^2-3)
= 3x-1 + 2x^2-3
=5x^2-4

can someone tell me if its correct, im not sure if i am ;-;​

Answers

Solution:

f(x) = 3x - 1 = 0

f(x) = x = 1/3

By putting the value of x in g(x), we get

g(x) = 2(1/3)^2 - 3

g(x) = 2(1/9) - 3

g(x) = 2/9 - 3

g(x) = -25/9

Answer:

g(x) = -25/9

Answer:

[tex]2x^{2} + 3x - 4[/tex]

Explanation:

(f + g)(x)=(3x-1)+(2x^2-3)

Simplify:

2x^2+3x−4

A loaf of bread has a mass of 0.5kg and a volume of 2500cm³. what is the density of the bread

Answers

Density is mass divided by volume.

Since mas is 0.5kg we need to convert it to grams. Using conversion factors we get the mass of the bread to be 500g.

So densty=500/2500

density =1/5 grams per cubic centimeter

What do you think happens to the matter in a food sample as it is burned?

Answers

Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed

The thing that is happen in a food sample as it is burned is the chemical and physical change.

What is combustion reaction?

Comubustion reactions are those reactions in which organic compound get burnt in the presence of oxygen for the formation of carbon dioxide gas and water molecule.

If the food sample contains the organic compound then it will convert into water and carbon dioxide gas and if it contains the matter in the form of inorganic compounds then it will convert into another product but having the same mass.

Hence if matter of food sample is burned then it will convert into small products as a result of physical or chemical change.

O The Zn and HCl both retained their identity
Either Zn or HCI, but not both, retained its identity
O Evaporation of one of the substances occurred
One or more new substances formed

Answers

Answer:

Hydrogen gas and a salt formed at the end of the reaction.

Explanation:

Hydrogen Gas has formed which inflated the balloon

Usually, metals and acids react to form a salt and Hydrogen Gas.

Here's what happened:

Answer:

One or more new substances formed.

Explanation:

This is an example of a chemical property because bubbles formed, and the mixture produced a gas which allowed the balloon to inflate. The production of bubbles is an indicator of a chemical change. When a chemical change occurs, one or more new substances form as a result.

3/4 needs to be times by 4

so it's

12/16 then you minus 7/16

the answer is

5/16

Answer: 5/16

Explanation:

Multiply tonys 3/4 by 4 in order to get the same denominator as mike's 7/16. You should get 12/16 since 4x3=12, and now you can subtract the smaller fraction 7/16 from the bigger one 12/16, you should get a difference of 5/16.

Scientist at the CDC (Center for Disease Control) in Atlanta, GA are currently developing and testing new treatments and vaccines for the coronavirus. What kind of research are they conducting?

Answers

Answer:

Applied research

Explanation:

The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.

This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.
