Let
be the amount of the 30% alloy and
the amount of the 60% alloy the metalworker will use. However much is used, the final alloy will have a mass of

kilograms. For each kg of the 30% alloy used, 0.3 kg is copper; similary, each kg of the 60% alloy contributes 0.6 kg, so that

Now,






Answer:
58075

Answer:
X is 12 Y is 124
Step-by-step explanation:
left and right side have equal degrees of 56
so x would be 12 because you would multiply 4×12
since in total it will be 360 degrees
you add 56 and 56 together to get 112
then just subtract 112 from 360 and you get 248 then divide 248 by 2 and you have your bottom and top value of 124
Answer:
x = 125
Step-by-step explanation:
4 hrs : 200 mi
2.5 hrs : x mi
4/2.5 = 1.6 hrs
200/1.6 = 125 mi
x = 125 mi
Well,
26.50
In this case, the hundredths place is the 0.
Since there are no more digits after that, 26.50 must already be rounded to the nearest hundredth.
26.50 is the final answer.
