Answer:

33.49 cubic units

Step-by-step explanation:

V_{sphere}  =  \frac{4}{3}  \times  \pi {r}^{3}  \\  \\ V_{sphere}  =  \frac{4}{3}  \times  \pi {(2)}^{3}  \\  \\  V_{sphere}  =  \frac{4}{3}  \times  \pi  \times 8 \\  \\ V_{sphere}  =  \frac{32 \times 3.14}{3}  \\  \\ V_{sphere}  =  \frac{100.48}{3}  \\  \\ V_{sphere}  = 33.4933333\\  \\ V_{sphere}   \approx 33.49\: units^3

Stevens and Sons Painting won the bid to paint 4 identical houses. Mr. Stevens painted the first house in 5 days. One of his son
Sladkaya [172]
In one day, Mr. Stevens painted 1/5 of a house.
Each son paints 1/4.5 of a house in one day.

If Mr. Stevens and his two sons work together, the would paint (1/5+1/4.5+1.4.5)=(9/45+10/45+10/45)=29/45 of a house in one day.

It will take them 1/(29/45)=45/29 days to finish painting the house, assuming their work is additive, like no waiting for drying for the second coat, etc.

Two sides of a triangle have the following measure of 7,8.what is the range of possiable values for the 3rd side?
astraxan [27]
The third side of the triangle could be between 1 and 15 units, exclusive. This is because there is a theorem in geometry that states that, if you add 2 of a triangle's sides, the third side has to be less than the sum of the first two sides. This means that the third side has to be less than 8 + 7 = 15. So the third side is less than 15 units. This also means that the third side plus another side has to be greater than the last side. To find the minimum value, you take the smallest side, in this case, 7, and create an inequality. The inequality would be 7 + x [the third side] > 8. Solving this inequality, you get that x > 1. This means that 1 < x < 15. That is the range of values for the third side.

The ratio of children to adults at the football game was 23. If there were 140 children at the football game,
inessss [21]

Answer:

Therefore, the number of adults at the football game was 6.

Step-by-step explanation:

Let A represents the number of adults and C represents the number of children.

Therefore, the ratio of children to adults is given as follows:

23:1 = C:A ....................... (1)

Since C = 140, this is substituted into equation (1) as follows:

23:1 = = 140:A ....................... (2)

Transforming equation (2) and solve for A, we have:

23 / (23 + 1) = 140 / (140 + A)

23 / 24 = 140 / (140 + A)

0.958333333333333 = 140 / (140 + A)

0.958333333333333 (140 + A) = 140

(0.958333333333333 * 140) + 0.958333333333333A = 140

134.166666666667 + 0.958333333333333A = 140

0.958333333333333A = 140 -134.166666666667

0.958333333333333A = 5.833333333333

A = 5.833333333333 / 0.958333333333333

A = 6.08695652173878

Rounding to a whole number, we have:

A = 6

Therefore, the number of adults at the football game was 6.
