Answer:
∛50 cm, 2∛50 cm, 3∛50 cm
Step-by-step explanation:
V= wlh
V=300 cm³
w= 1/3l
h= 2/3l
---------
- l*1/3l*2/3l=300
- 2/9l³=300
- l³= 1350
- l= ∛1350= 3∛50 cm
- w= 1/3*3∛50= ∛50 cm
- h= 2/3*3∛50= 2∛50 cm
Ratio of height of the man to the length of the shadow = 6:9 = 2:3
Ratio of height of the tree to the length of its shadow = x:25 = 2:3
x/25 = 2/3
x = (25 x 2)/3 = 50/3 = 16.67
Therefore the approximate height of the tree to the nearest foot is 17 feet.
Answer:
A. j > 11
B. x ≥ 8
Step-by-step explanation:
For A if 7j is greater than 77, then j has to be more than 11. 7 x 11= 77.
For B x has to be greater or equal to 17, and 8+9 is equal to 17.
