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

13.At the Finch School bake sale, donuts sell
aliina [53]

Answer:

c)

Step-by-step explanation:

create a system of equations:

d + m = 104

2d + 3m = 243

now use substitution method based on 'd = 104 - m'

2(104 - m) + 3m = 243

208 - 2m + 3m = 243

208 + m = 243

m = 35

So, 35 muffins and 69 donuts were sold.

This is 34 more donuts than muffins.

If she saves 1$ the first week 3$ the season week 9$ the third week how much will she save in 5 weeks
ycow [4]

Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).

Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.

Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.

Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks
