Answer:
Let the proportion of the $0.20 be x
Then the proportion of the $0.68 is 1−x
Set the target at $0.54
Dropping the unit of measurement ($ ) for now we have
0.20x+(1−x)0.68=1×0.54
0.20x−0.68x+0.68=0.54
−0.48x+0.68=0.54
Lets get rid of the decimals for now and multiply everything by 100
−48x+68=54
48x=68−54
x=1448
x=724 of the blend at $0.20
So the proportion of the $0.68 is 1−724=1724
The surface area is 13.08 and the volume is 3.14
Step-by-step explanation:
74 is total surface area
keeping in mind that there 60 seconds in 1 minute, and about 1.609 kilometers in 1 mile.
