4/6 = 12/18
8/10 = 16/20
2/5 = 4/10
1/4 = 4/16
Can I get brainiest please.
Answer:
A= ~2.55
Step-by-step explanation:
Using Pemdos, or gemdos, you can find you do the exponent first
4^2 = 16
then to everything else in left to right order since they're all multiplication or division
22/7 = ~3.14 * 13 = ~40.86/16 = ~2.55
(I'm using "~" to mean about/rounded to)
Solution :
Volume of ball = Volume of outer ball - Volume of inner ball

Now, density of iron is, d = 7300 kg/m³.
So, mass of iron ball is :

Hence, this is the required solution.
112 is 80% of 140.
80% can be written as 0.80 or 0.8.
how i got 140 is by finding the x value of this equation: 0.8x=112
to find the x, i divided 0.8 from both sides,
0.8 divided by 0.8 cancel out.
112 divided by 0.8 is 140.
therefore, 112 is 80% of 140
