The problem is simply asking us to convert the units from BTU to units of foot pound force. To do this, we use the conversion ratio 1 BTU/778.169 ft-lbf. We do as follows:
1500 BTU/hr ( 777.169 lbf-ft / 1 BTU ) = 1165753.5 lbf-ft/hr
Hope this answers the question.
Answer:
Step-by-step explanation:
Change 2/5 to a decimal
2/5 = 0.4
Change 1 2/15 of a fluid ounce to a decimal.
1.133333
Set up your proportion.
0.4 / 1.133333 = x / 5 Cross multiply
0.4*5 = 1.133333*x
2 = 1.133333 x Divide by 1.1333333
2/1.33333 = x
x = 1.5 ounces.

Answer:
The total cost of the party (C), can be expressed as;
C=10 n+30, where n is the number of children
Step-by-step explanation:
Step 1
We can use the expression below to calculate the total cost of the party as shown;
C=F+(V×n)
where;
C=total cost of the party
F=fixed cost to design party
V=cost per child
n=number of children at the party
In our case;
F=$30
V=$10
n=n
replacing;
C=30+(10×n)
C=30+10 n
The total cost of the party (C), can be expressed as;
C=10 n+30, where n is the number of children
