The sum of the adjacent angles of a parallelogram is always equal to 180°.
So we know that
.
When we simplify that expression:
Isolate the y by divide both sides by 3:
It’s either B or D. I’m sorry I’m not so sure but I think it’s either one of those.
When working a bunch of these, it is useful to program your calculator or a spreadsheet to do the number crunching. Here, I've defined Y₁(X) to give both the area and volume of a sphere of radius X.
1. Area = 113.097 cm^2
.. Volume = 113.097 cm^3
2. Area = 50.265 in^2
.. Volume = 33.510 in^3
3. Area = 314.159 cm^2
.. Volume = 523.599 cm^3
4. Area = 201.062 in^2
.. Volume = 268.083 in^3
5. Area = 31415.93 cm^2
6. Volume = 7238.23 in^3
Answer: 70% as a decimal is 0.7.
Step-by-step explanation: "Per" means 100. To find the decimal, divide 70 by 100.
70 / 100 = 0.7
Hence, that is our answer.
70% as a fraction is 70/100.
Again, Per means 100. To get that answer, look at the decimal. The number 7 is 7 tenths. Since it means tenths, instead of 100, put 10.
Hence, 70/100 and 0.7 is the answer.
