Answer:
The heat is produced by a 150-W light bulb that is on for 20-hours is 10200 BTU.
Step-by-step explanation:
To find : How much heat (Btu) is produced by a 150-W light bulb that is on for 20-hours?
Solution :
A 150-W light bulb is on for 20-hours.
The heat produced by bulb is given by,
We know that,
Converting W-hr into BTU,
Therefore, The heat is produced by a 150-W light bulb that is on for 20-hours is 10200 BTU.
- - Solve:
Start of by simplifying both sides of your problem.
3*2x+3*-7=32
6w+-21=3
6w-21=3
- - Now you need to add 21 to both sides to be able to finish solving.
6w-21+21=3+21
6w=34
- - Final step:
Answer: w=4
Start of by simplifying both sides of your problem.
3*2x+3*-7=32
6w+-21=3
6w-21=3
- - Now you need to add 21 to both sides to be able to finish solving.
6w-21+21=3+21
6w=34
- - Final step:
Answer: w=4
Answer:
---- Set Builder
(50, ∞) ---- Interval Notation
Step-by-step explanation:
Given
x > 50
Required
Write as a
- Set builder
- Interval notation
As Set Builder:
x > 50 means that x is an integer and x is greater than 50.
In set builder notation, integers are represented with z.
So, the above can be represented as:
This translates to:
x is a member of the set of integers such that x is greater than 50
As Interval Notation:
In interval notation, we make use of brackets to represent the intervals.
In this case > is represented by (a,b)
Where a and b are the intervals of the notation
Since x > 50, then a = 50 and b = ∞ because we only know the starting point and not the end point.
<em>Hence: x > 50 in interval notation is (50, ∞)</em>
