The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.
Answer:
B 720 sq m
Step-by-step explanation:
A= 24^2 + 12^2
= 720 sq m
Answer:
option C 2*x + 3*y = 7.20
4 *x + 2*y = 8.80
1.4
Step-by-step explanation:
PART A
Steve
2lbs of grapefruit
3lbs oranges for $7.20
kennedy
4lb grapefruit
2lb oranges for $8.80
price 1 pound grapefruit x
1 pound oranges y
Then for steve
2*x + 3*y = 7.20
for kennedy
4 *x + 2*y = 8.80
PART B
now we have to find y from above equations
2x + 3y = 7.20 multiply by 2 on both sides 4x + 6y = 14.4
4x + 2y = 8.80
next by substracting the above two equations we get
6y - 2y = 14.4 - 8.80
4y = 5.6
y = 1.4
The roller coaster is an illustration of a right triangle
- The equation needed to solve the horizontal distance is
- The horizontal distance is 16.58 feet
<h3>How to determine the equation</h3>
The height is given as: 25 feet.
From the complete question, the length of the roller coaster is 30 feet.
Represent the horizontal distance with h.
Given that the roller coaster represents the hypotenuse side length, the following equation can be used to find h
Collect like terms
<h3>The horizontal distance</h3>
In (a), we have:
This gives
Take the roots of both sides
Hence, the horizontal distance is 16.58 feet
