$54
30 divided by 5 is 6. then 6 times 9 is 54
Answer:
2%
Step-by-step explanation:
x is percentage (%)
490+(490*x)= 499.80
490*x=9.80
x=9.80/490
x=2/100
x=2%
Answer: 59.49 meters
In this case, Gabriella flew 4 times with different distance. To answer this question you just need to add all the distance, The calculation would be:
Total distance = distance 1 + distance 2 + distance 3 + distance 4
Total distance = 8.05 meters+ 17.71 meters + 14.38 meters + 19.35 meters= 59.49 meters.

Answer: 2*3*3*5 which is the same as 2*3^2*5</h3>
====================================================
Explanation:
Divide by the smallest prime 2
90/2 = 45
Then divide by the next smallest prime 3 (since 2 won't go into 45)
45/3 = 15
Repeat the last step
15/3 = 5
We stop because the result is prime.
Note the denominators are 2, 3, 3. The final result is 5 which is prime.
So the prime factors are 2, 3, 3, and 5
They multiply to 2*3*3*5 = 90.
We can condense it to 2*3^2*5 = 90 because 3*3 = 3^2.
Calculate the volume of sand, the cone will be completely filled and the cylinder will have sand up to the 30 mm level.
Volume of sand will = the volume of the cone:
= 1/3 * pi * (6 mm)^2 * 15
= 1/3 * pi * 36 * 15 =180 pi cubic mm
the cylinder will have a volume of sand equal to:
= pi * (6 mm)^2 * 30 mm
= pi * 36 sq mm * 30 mm
= 1080 pi cubic mm
The total sand is the sum:
= 1080 pi cubic mm +180 pi cubic mm
= 1260 pi cubic mm.
