Answer:
acres of land
Step-by-step explanation:
Given:
Number of trees on 1/2 of the land owned by Jill = 150
There are 5 trees for every 1,000 square feet of land.
To find: Acres of land owned by Jill
Solution:
As there are 5 trees for every 1,000 square feet of land,
150 trees are on ×1000=30000 square feet of land
Now as Jill has 150 trees on 1/2 of the land, so total land owned by Jill = 2×30000 = 60000 square feet of land
As 1 acre= 43,560 square feet,
Jill owns acres of land
Remember that sec=1/cos:
Invert both members:
Consider the arccos of both sides:
Arccos and cod simplify:
Add 15 to both sides:
Divide both sides by 2:
the volume formula is sideXsideXside
so your equation is 4.8X4.1X15=295.2
Answer:
Step-by-step explanation:
1. 2x + 6 + 4x = 6x + 6
2. 4 + 2x - 4 - 4 = 2x - 4
3. 12x - 24 - 3x = 9x - 24
4. -x + 3
