Answer:

3.349 \times {10}^{ - 10} \:  {mm}^{3}

Step-by-step explanation:

d = 4 \times  {10}^{ - 3}  \: mm \\ r = 2 \times  {10}^{ - 3}  \: mm \\ V_{sphere}  =  \frac{4}{3} \pi {r}^{3}   \\ = \frac{4}{3}  \times 3.14 \times {(2 \times  {10}^{ - 3} )}^{3} \\  = \frac{4}{3}  \times 3.14 \times 8\times  {10}^{ - 9}  \\ = \frac{100.48}{3}  \times   {10}^{ - 9}  \\  = 33.4933333\times   {10}^{ - 9}  \\  = 33.49 \times {10}^{ - 9} \\  = 3.349 \times {10}^{ - 10} \:  {mm}^{3}

19x+rx=−37x+w solve for x
Oksanka [162]
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)

A rectangular room measures 14 feet by 144 inches. Edgar said the area of the room is 2,016 square feet. Explain his mistake, th
valina [46]
Change the inches into feet. There are 12 inches in a foot so divide 144 by 12. That gives you 12, so then multiply 12 by 14. You are left with 168 feet.

Hello please help me! There are 3 questions, I will give brainliest!
Shalnov [3]

Answer:

1) There are 13 students in Jerry's study.

2) There are 39 students in Kathy's study.

3) Jerry's study is more trustworthy!

Step-by-step explanation:

1) Jerry's study is the one with the dot plot.

Now, the number of students is calculated by adding the total number of dots in the plot.

We have a total of 13 dots.

Thus, there are 13 students in Jerry's study.

2) Kathy's study is the one with the histogram.

The total number of students is gotten by adding the corresponding number of students on the y-axis for each range of distance on the x-axis.

Total number of students = 9 + 11 + 7 + 12 = 39 students

3) Jerry's study where he used a dot plot is likely to be more trustworthy because it gives exact values of the number of students for each distance represented whereas, Kathy's study where she used a histogram doesn't give exact values but just gives a range of distances for a particular number of people.
