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:
Step 1: Calculate the change by subtracting old cost ($52) from the new cost ($64)
Step 2: Divide that change by the old cost ($52). You will get a decimal number
Step 3: Convert the decimal number to a percentage by multiplying by 100%
Answer: 5/9
Solution: 2x^2+16x-10=0
According to formula: X=(-16+_sqrt(16^2-(-10•2)) / 2•2
X=5/9
Answer:
Step-by-step explanation:
The general formula for slope-intercept form is y = mx + b
We can see that m (slope) equals 1/3 here. We can also see that the y-intercept (b) is -2. Another way to find the y intercept is to make x equal to 0. You get 0 - 2 which equals -2
Note:
If youre ever asked for the x-intercept, make y equal to zero and solve for x.
