DCAB would be 100. I'm pretty sure DCAB would be 100 because if DDAC is 20 that means the letters D,C, and A are 5. So if D,C, and A are all equal to 5 then B is equal to 85.
The earths crust depth in kilometers is 6.4 kilometers I hoped this helped
Solution:
<u>Note that:</u>
- Percentage formula: x/100 × y = x% of y
<u>Use the formula to solve 20% of 180.</u>
- x/100 × y = x% of y
- => 20/100 × 180
- => 1/5 × 180
- => 36
20% of 180 is <u>36.</u>
