Arranged in descending order means the terms are arranged in the order of the exponent, from the largest to the smallest. the exponent is the little number up right to y,
3y^4+6y^3+2Y^2-5y
so the third term is 2y^2
Answer:
x = 38°
Step-by-step explanation:
x and the 142° angle are supplementary angles, meaning they add up to 180°
x + 142° = 180°
Subtract 142 from both sides.
x = 38°
Answer:
525 minutes
Step-by-step explanation:
3 weeks is 21 days because each week is 7 days.
in 1 week of reading it will be 25*7=175 mintues in 1 week
now becuase there is 3 weeks not 1 we will do 175*3 which is 525 minutes
Answer:
9 percent of 578 is 52.02.
Step-by-step explanation:
578/x=100/9
(578/x)*x=(100/9)*x - we multiply both sides of the equation by x
578=11.111111111111*x - we divide both sides of the equation by (11.111111111111) to get x
578/11.111111111111=x
52.02=x
x=52.02
The correct answer for the given question is B. Heat is written as a reactant in the equation.
<h3>What is endothermic reaction?</h3>
An endothermic reaction is a reaction in which is reactants absorbs heat from the surrounding to give the product or heat supplied is the reactant.
Suppose if A and B are reactants that forms product C and D,
and H be the heat absorbed or supplies to the reactants.
Then for an endothermic reaction we can write-
A + B + Heat ---> C + D
Since, Heat is absorbed at the reactant side then it is called as endothermic reaction.
Hence,the correct answer for the given question is B. Heat is written as a reactant in the equation.
