Use the KCF method to divide
3/6 / 5/2 = 3/6 x 2/5, which equals 1/5
Hope that helps :)
62.50 * .18 = $11.25
Add tip-
11.25 + 62.50 = 73.75
Total - $73.75
The answer would be:
93
+75
-------
168
Angle ABC is an inscribed angle so would be half of the arc.
So, 4x-5.5=1/2(5x+25)
4x-5.5=5/2x+25/2
4x-5.5=2.5x+12.5
4x-2.5x=12.5+5.5
1.5x=18
x=12
So angle ABC=4(12)-5.5=48-5.5=42.5
Arc AC=5(12)+25=60+25=85
Check: 42.5(2)=85
Answer: Arc AC is 85
Answer:
Alloy = 12.6 lbs.
Step-by-step explanation:
( 2/7 ) = ( Nickel /4.9)
Nickel = 1.4 lbs.
Ratio of Copper to Zinc:
( 9/7 ) = ( Copper /4.9)
Copper = 6.3 lbs.
Alloy = Zinc + Nickel + Copper
Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.
Alloy = 12.6 lbs.
