Answer:

1. 247 mg ÷ 10 = 24.7 cg

2. 247 mg ÷ 100 = 2.47 dg

247 mg ÷ 1000 = 0.247 g

Step-by-step explanation:

1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.

2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.

3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.

Number 2 and please provide a step by step explanation!!!!
Alekssandra [29.7K]

The number of students in 5th grade is 60, since 24% of 250 is 60.

Since 90 is 38% if 250, 38 is going to be the percent of all students in sixth grade.

20% of 250 is 50, so the percent of all students in seventh grade is 50.

Finally, 45 is 18% of 250, so 18 percent of all students are in eight grade.

Hope this helped :)

a white-tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 per minute. Which
guajiro [1.7K]
For the answer to the question above,
In 1 minute, bison runs 3520 feet
In 60 minutes, the bison would run
3520*60 feet
211200 feet per hour.
These are equivalent to;
40 miles per hour since 1 mile is equivalent to 5280 feet.
The bison is faster by 10 miles per hour
Then If you convert the bison's speed to mph you get that it can run at speeds up to 40 mph.

I got this by seeing how many feet that they run in one hour so 3520 x 60 is 211200 which divided by 5280 is 40 mph.

I hope my answer helped.
