Radius I think is 4
Because 8/2=4 and the diameter is 2 times the radius
Check work:
4*2=8
Have a awesome night/day
Answer:
six less than a number is n-6
Step-by-step explanation:
n-6
So, the ration is 17:3, you know that. Therefore, the change from # of students to the 17 is the same change as # teachers to 3. Knowing this, you also know that the total # of people ihas the same change as the total ratio. So 17+3 = 20. 740/20 = 37. So the change is 37. 3x37= 111 17x37=629
You can check to make sure this answer is correct by adding the two final numbers. 111+629 = 740. (Some find it easier to see lined up really pretty)
17 -- 3 total 20
x -- y total 740
Or, if you are visual, look at the picture I drew:
1) It takes 1435.75 hours for Mercury to complete a full rotation.
2) The weed can grow at 0.445 inches per hour.
<h3><u>Time calculation</u></h3>
1) Given that to make a full rotation, 59 days, 19 h, and 45 min goes by for Mercury, to determine how many hours does it take Mercury to complete a full rotation, the following calculation must be performed:
- 59 x 24 + 19 + 0.75 = X
- 1416 + 19.75 = X
- 1435.75 = X
2) Given that a plant grows up to 0.89 ft per day, to determine how fast in inches per hour can this weed grow, the following calculation must be performed:
- 0.89 / 24 = ft per hour
- 0.037 = ft per hour
- 1 ft = 12 inches
- 0.037 x 12 = 0.445
