Answer:
Answer:574.9ft^3.
Step-by-step explanation:
radius (r) = 6.5feet
π=3.14
volume of hemisphere=2/3 x π x r^3
Volume=2/3 x 3.14 x (6.5) ^3
Volume=2/3 x 3.14 x 6.5 x 6.5 x 6.5
Volume = (2x3.14x6.5x6.5x6.5) ➗ 3
Volume=1724.645 ➗ 3
Volume=574.9ft^3
for a put 6 and b put -9
Explain: 6(-9) is equal to -54
and 6- -9 is 15 because the minus turns into a plus sign and the negative number turns into a positive number.
Answer:
The length is 5 inches.
Step-by-step explanation:
9/3=15/?
If you divide 9 by 3, you get 3 if you compare things you have to do the same on the other 'side'. So you do 15 divided by 3, the answer is 5.
Answer:
3.08 km/h.
Step-by-step explanation:
We know that,
Ali traveled at a speed of s km/h for 2.5 hours.
Let d be the distance and t be the time.
...(1)
On his return journey, he increased his speed by 4 km/h and saved 15 minutes. So, distance is d and times is t-15.
...(2)
From (1) and (2), we get
Put t=40 in (1).
So, t=40 and d=100.
Now,
Total distance = d + d = 100 + 100 = 200
Total time = t + t - 15 = 40 + 40 - 15 = 65
So, the average speed is
Therefore, the average speed is 3.08 km/h.
So first, you will do $10.05x2
Then add the product of that to $18.95
Next you will get the sum of that and multiply it by 7%
Finally you will round to the nearest hundredth (0.01)
