Answer:
B
Step-by-step explanation:
The dots are pretty close to each other and are going negatively so there is a correlation ( so C and D can't be right) and the dots are going negative ( so A can't be right) meaning B is right :)
The first thing you should remember is that the energy in this case will be given by the work done.
The work is defined as:
W = F * d
Where
F = Force
d = displacement.
Calculate it.
5 kg x 9.8 m / s ^ 2 x 21 m = 1029 J
Answer:
E, 297.1
Step-by-step explanation:
First, find the area of the triangle using the formula a= (bh) / 2
Base x height would be 16 x 12, which is 192
192 / 2 is 96 sq meters
Then, find the area of the circle using the formula a= Pi (r^2)
If the diameter is 16, the radius would be 8 because you divide by 2
8^2 is 64, 64 times Pi is approximately 201.1
Finally, add the areas together, 96 + 201.1 is 297.1 or E
Answer:
C. 28 fewer
Step-by-step explanation: Total population of students and teachers = 510
Students : teacher = 16 : 1
Population of students = 16/17 × 510 = 480 students
Number of kindergarten students = 1/5 of 480 = 1/5×480 = 96
Number of grade 5 and 6 students = 1/3 of (480 - 96) = 1/3×384 = 128
Number of grade 1 and 2 students = 1/4 of 480 = 1/4×480 = 120
Number of grade 3 and 4 = 480 - (96+128+120) = 480 - 344 = 136
Number of grade 3 students = 136/2 = 68
Number of kindergarten students = 96
Therefore, the number of students in grade 3 is 28 (96 - 68 = 28) fewer than the number of students in kindergarten
