3 * 54/100
3/1 * 54/100 = 162/100
1 62/100 = 1 31/50
Answer: 1 and 31/50
now simply just multiply the numerators and denominators;
3 × 54 = 162
100 × 1 = 100

You would multiply the two terms which are -6y^2 and -13x^2*y^5.
Multiplying -6 by -13 yields 78, which will be the new coefficient.
Since there is only the x^2 from the second term, that remains the same. However, there are two y values that we can multiply together: y^2 and y^5. y^2 * y^5 = y^(2 + 5) = y^7.
Therefore, your answer is 78x^2*y^7.
The test tube is warm.
The test tube is very hot.
The test tube is the same temperature as the air.

The testtube is cold best describes what is felt.
Option A is the correct answer.
What is a chemical reaction?
A chemicalreaction is a process that leads to the transformation of one set of chemical substances into another.
In other words, it is the process of breaking and forming chemical bonds between atoms to create new compounds with different properties than the original substances.
We have,
An endothermicreaction is a type of chemical reaction that absorbs heat from the surrounding environment, resulting in a decrease in temperature.
In this case,
The chemicalreaction that occurred in the test tube absorbed heat from the surroundings, including the air and the test tube itself.
As a result, the temperature of the test tube decreased, making it feel cold to the touch.
Thus,
The testtube is cold best describes what is felt.

Final answer:
In an endothermic reaction, the test tube will feel cold because heat is absorbed by the system from the surroundings.
Explanation:
A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. In the course of an endothermic process, the system gains heat from the surroundings, and so the temperature of the surroundings decreases.
The quantity of heat for a process is represented by the letter q. The sign of q for an endothermic process is positive because the system is gaining heat.
A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases.
The sign of q for an exothermic process is negative because the system is losing heat.
