well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).
Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.
Answer:
40
Step-by-step explanation:
Since the probability to choose a blue marble is 1/9, there must be 5 blue marbles since 45 * 1/9 = 5
Subtract 5 from 45 to get 40, since the rest of the marbles are red.
Step-by-step explanation:
55 + 55 ÷ 55
= 55 + 1
= 56

Percent means parts out of 100
15%=15/100
'of' means mutily
15% of 60=15/100 times 60=900/100=90/10=9/1=9
easy way is
15%=10%+5%
10% of 60=6
5%=1/2 of 10%
10%=6, 1/2 of 6=3
10%+5%=6+3=9
answer is still 9
Answer:
orders of magnitude.
Step-by-step explanation:
We know that 900 km is equivalent to 20 cm, because we need to fit the United Kingdom length on a sheet of paper. So:
- 1 cm in a paper will be 45 km in the real ground.
Therefore, if we divide 45 km by 0.00001 km (1 cm) we will have times to scale down.
I hope it helps you!
