8.34 * 3 = 25.02
8.34 * 0.5 = 4.17
25.02 + 4.17 = 29.19
Explanation:
As we know that set is the collection of elements and set builder is the method of defining the set with the help of specific property in which we can use arithmetic operations as well
Generally,
It is the general form of any set in which we can construct the complete set with the help of equation in the given in set builder form.
Since we have the elements : 45,55,65,75
So, the set builder form will be { x: x =5(2n+1) ,4≤n≤7,x,n∈ N }
We will read it as it is the value of x which will be find with the help of given equation i.e. x=5(2n+1) where n goes from 4 to 7 only and x and n are natural numbers only.
Answer:
c. Climax
Step-by-step explanation:
Climax community is an ecological community in it final stage of succession, in which the species that makes up the community are relatively stable unless a rare earth disaster like earthquakes, fire etc destabilize the system.
The climax community has reached the stable stage. The community is well defined and extensive . This stability is usually actualized when more complex organisms replace more simple organism. Succession in this kind of community has occurred severally until it reaches it reaches the climax stage. Most climax community takes hundreds and millions of years to reach stability. This stability is achieved through succession : a process whereby natural communities is replaced by another. For example grass may invade an ordinary flat sandy surface then the grass will provide humus for other more complex species to grow like oaks and beeches tree before it reaches a stable community.
Answer:
A
Step-by-step explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
Answer:
The mileage of the car is 30 miles per gallon
Step-by-step explanation:
Here, we are interested in calculating the gas mileage of the car.
The gas mileage refers to the number of kilometers the car can travel on a particular amount of fuel.
The full capacity of the car tank is 15 gallon
Now after traveling 300 miles, it stops for gas and 10 gallons of fuel are added to make the car full again.
What this means is that the car used up a total of 10 gallons of fuel for the 300 miles
Thus, the gas mileage of the car is that it used 10 gallons to travel a total of 300 miles
Expressing this as a ratio, we have 300 miles/10 gallons = 30 miles/ gallon
This means that on a gallon of fuel, the car can travel 30 miles
