Add the soil mixtures so 2m3 plus 6m3 and add the percentage.
Answer: x=2±√3
Step-by-step explanation:
For the first one (aka 7) you would write 10² wich is the same as 10×10 and so the answer is 100
For the second one (aka 8) you would write 3×3×3×3×3×3×3×3×3 and the answer is 486 square miles
This is a part:part ratio. to answer the question, we need to change it into a part:whole ratio. to do this we add up the parts to equal 7. so the ratio of girls to students is 3:7. divide 238 (whole) by 7 (whole) to equal 34. now we multiply 34 by 3 for girls and by 4 for boys. girls: 102; boys: 136.
