Option 4. x>2 should be an open circle on 2 going right. x<=-2 should be a closed circle on -2 going left. Remember, < equals open circle and <= equals closed circle.
Answer:
1750 trees
Step-by-step explanation:
Scale :
1 inch² = 1 mile²
Number of pine trees per square inch = 35
Area of model = 50 inch²
Hence,
Since scale factor is ; 1 inch² = 1 mile²
Area of forest will also be 50 mile²
Approximate number of trees on forest ;
Area * number of trees per square inch
50 * 35
= 1750 pine trees
Answer:
Volume = = 138⁶/32 cubic meters
Step-by-step explanation:
Given:
Length = 8⅜ m
Width = 2 m
Height = 8¼ m
Required:
Volume as a mixed number
Solution:
Volume of rectangular prism = L*W*H
Plug in the values
V = 8⅜ × 2 × 8¼
Change to improper fraction
V = 67/8 × 2 × 33/4
= (67 × 2 × 33)/(8 × 4)
= 4,422/32
= 138⁶/32 m³
Answer:
6 miles in 1 hour
Step-by-step explanation:
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
