Answer:
30 J
Step-by-step explanation:
W = mg = 3 N
h = 10 m
Potential Energy = mgh = 3*10 = 30 J
Answer: 1.5
Step-by-step explanation:Let the standard deviation of the shoe size be represented by ' ' and the mean shoe size be represented by ' = 7.5'. Also, the sizes of the shoe be represented by ' '. So, . Hence, the standard deviation of the shoe size data for the math class is 1.5.
Answer:
336in^3
Step-by-step explanation:
The volume of a rectangulur prism can be found by multiplying the length of the box with its height and width.
Thus, we can find the volume using the solution below:
v=l*w*h
l = 12in
h = 7in
w = 4in
12*7*4 = 336in^3
Answer: (7/2)^2
Step-by-step explanation:
2:3:4 gives 9 equal parts.
1.20 divided by 9 is 0.133.
2 * 0.133 would be 0.266m
3 * 0.133 would be 0.399m
4 * 0.133 would be 0.533m
To check this calculate 0.533 + 0.399 + 0.266 would be 1.198m (close enough)
