A spherical container has a radius of 9 centimeters. It is filled with a solution that costs $2.10 per cubic centimeters.

Answer:

$8.19

Step-by-step explanation:

1. First, sum the prices of all items together

5.3 + 1.29 + 0.53 + 0.68 = 7.8

2. Next, calculate 5% of the total item cost

5% = 0.05

7.8 · 0.05 = 0.39

3. Finally, add the sales tax to the initial item total

7.8 + 0.39 = 8.19

Answer:

The resultant velocity will be 12 m/s

Step-by-step explanation:

If the river flows at 2m/s downstream while the boat travels downstream at 10m/s, simply add the two speeds to find the resultant velocity:

Resultant Velocity = 10 m/s + 2 m/s = 12 m/s.

Answer:

The fat percentage in the blend amounts to 8%.

Step-by-step explanation:

Let

x -----> represent the fat percentage in the mix.

We understand that

The total of milk's volume times its fat percentage, added to cream's volume times its fat ratio, must match the overall mixture's volume times its fat percentage.

Keep in mind that

15% = 15/100 = 0.15

3% = 3/100 = 0.03

therefore

Now, solve for x

Convert that into a percentage
