Answer:
--- of perimeters
--- of areas
Step-by-step explanation:
Given
Represent the sides of the first triangle with x, y and z
The sides of the second triangle will be 6x, 6y and 6z
Solving (a): Ratio of perimeter.
The perimeter of the first is:
The perimeter of the second is:
Factorize:
The ratio is:
Cancel out x + y + z
Solving (a): Ratio of Areas.
If the height of the first is h and the base is b.
The height of the second will be 6h and the base, 6b.
The area of the first is:
The area of the second is:
The ratio is:
Divide by 0.5bh
Answer:
18
Step-by-step explanation:
Answer:
1 gallon
Step-by-step explanation:
Since the relationship is direct, meaning as the number of square feet decreases, the number of gallons also decreases.
3:900 = x:300
solution:
3(300) = 900x
900=900x
x=1
Answer:
Vertex = (-3, -1)
Axis of Symmetry: x = -3
Step-by-step explanation:
The vertex is (-3, -1), the axis of symmetry is x = -3. The x-intercept is -2 and -4, the y intercept is 8, the domain is R, the range is [-1, inf.]
The function is increasing in {-3, inf.} and decreasing in {-inf., 3}
