175 students walk to school. 7+5=12 and 420 divided by 12 is 35. I checked how I did it was correct because of 5*35+7*35=420. Then I found the product of 5*35 which is 175.
Answer:
1. 490.6 mm²
2. 14.1 ft²
Step-by-step explanation:
1. 3.14×(12.5)²= 3.14 × 156.25 =490.6mm²
2. ½×3.14×3²= 3.14×4.5= 14.1 ft²
28/33 × 100% = 0.84848... × 100% ≈ 85%

Since we're not told the number of points per question, we don't actually have enough information to answer the question.
The complete question in the attached figure
we know that
The <span>probability on the first day is 3/5 since there are 3 novels out of 5 and when you take a book out at random, all of them have a equal chance of being picked. Since you returned the book to the bag, the next day too, we have the same probability. </span>
<span>Probability of a novel being grabbed both days is the product of the two probabilities-----> (3/5)*(3/5)----> 9/25
the answer is9/25</span>
