Answer: 5.6 N/cm^2
============================================
Work Shown:
Pressure = (Force)/(Area)
P = F/A
P = (84 N)/(15 cm^2)
P = (84/15) (N/cm^2)
P = 5.6 N/cm^2
For every square cm, 5.6 newtons of force is applied.

Extra info:
If you wanted to convert this to pascals, then you would need to convert 15 cm^2 to 0.0015 square meters. Then apply the formula above to get 56,000 pascals. 1 pascal is equivalent to 1 N/m^2.
X=real height of the tree
1 cm / 0.75 m=6.5 cm / x
x*1cm=0.75 m*6.5 cm
x=(0.75 m*6.5 cm) / 1 cm=4.875 m
therefore: the real height of a tree is 4.875 m,
Mrs. Cali's Lower Quartile:2
Mrs. Cali's Upper Quartile:4
Mr. Ronald's Lower Quartile:4
Mr. Ronald's Upper Quartile: 7
Lower Quartile 2<4 (Mr.Ronald's is greater)
Upper Quartile 4<7 (Mr.Ronald's is greater)
Mr. Ronald's Upper and Lower Quartiles are Greater than Mrs. Cali's Upper and Lower Quartiles.
Mr. Ronald's Lower Quartile:4
Mrs. Cali's Upper Quartile:4
D is correct because Mrs. Cali's upper Quartile is at 4, which is where Mr. Ronald's Lower Quartile is.
Hopefully that helps!
Good Job getting it right on your own!
Answer:
The first 4 are correct and the last one is incorrect
Step-by-step explanation:
1. The diameter of the circle is 30.8 m ( Correct )
Radius = 15.4 so diameter is 2 times the radius which is 30.8 m
2. The circumference in terms of π is 30.8 π ( Correct )
Circumference = π × Diameter
Circumference = π × 30.8
Circumference = 30.8 π
3 . The circumference of the circle can be found using 2 × π × 15 . 4 ( Correct )
Circumference = π × Diameter
Circumference = π × 30.8
Circumference = 30.8 π
4 . The approximate circumference of the circle rounded to the nearest tenth is 96.7 m ( Correct )
Circumference = 30.8 π = 96.7610537306
5 . A little more than 6 diameters could be wrapped around the circle
( False )
Circumference = 96.7610537306
Diameter = 30 . 8
96.7610537306 ÷ 30 . 8 = 3.14
