The first thing we must do for this case is find the amount of BTU produced by the 20 people.
We have then:
Then, we must find the volume of The ice sand, which we can model as a rectangular prism:
Where,
l: length
w: width
h: height
Substituting values we have:
Then, we look for the BTU rate per cubic foot.
We have then:
Answer:
B. .525 BTUs per cubic ft
Answer:
The solution is (-1,-8)
Step-by-step explanation:
Equation 1 :6x−2y=10
Equation 2 : 10x−y=−2
Multiply equation 1 by 1 and Equation 2 by 2
So, Equation 1 will be : 6x-2y=10
So, Equation 2 will be : 20x-2y=-4
Subtract 1 from 2
So, 20x-2y-6x+2y=-4-10
14x=-14
x=-1
Substitute the value of x in 1
So,6(-1)-2y=10
-6-2y=10
-16=2y
-8=y
Check solution:
Substitute the values in equation 1 :
6x−2y=10
6(-1)-2(-8)=10
-6+16=10
10=10
Hence Verified
So, The solution is (-1,-8)
<span>Answer:
When bob starts walking The distance between them is 45-3 = 42 miles
If they meet at time t then Yolanda would have walked
X/3 minutes and Bob would have walked (42-X)/4 mins
X/3 = (42-X)/4 so X = 18
Bob would have walked 42-18 = 24 miles.</span>
Answer:
1. 0.507
2. 5.006
3. 9.062
Step-by-step explanation:
If a value has “thousandths” in the question, the decimal place goes 4 places to the left: ex. 0.007.
