Answer: 9.202 x 10²
8.6x107= 920.2
256 * 40 = 10,240 cm needed
so if the balls are 30 cm each then
10, 240 divided by 30 = 341.3
so the teacher will need 342 balls.
Answer:
The answer to this question is D.60
Answer: 240 people get the news from social media
Step-by-step explanation:
The ratio of the number of people who get their news from social media to the number of people who their news elsewhere is 3:7
Total ratio is the sum of the proportion of those that get their news from social media and those that got their news elsewhere.
It becomes 3+7 = 10
Total number of people in the town is 800
To determine the number of people that got their news from social media, we will divide the proportion of those that get their news from social media by the total ratio and multiply by the total number of people in the town. It becomes
3/10 × 800 = 240
