Percent mean parts out of 100
0.2%=0.2/100=0.02/10=0.002/1=0.002
'of' means multiply
'what number'=x
'is' means '='
so
0.2% of what number is 12
0.002 times x=12
divide both sides by 0.002
x=6000
the number is 6000
An unknown variable ..............
Answer:
first one x = 26
second one x = 11.12
Step-by-step explanation:
a^2 + b^2 = c^2
24^2 + 10^2 = c^2
676 = c^2
26 = c
a^2 = c^2 - b^2
a^2 = 12^2 - 4.5^2
a^2 = 123.75
a = 11.12
<u>Answer:</u>
