Determine the scale measurement in centimeters
The scale can be represented as:
Substitute 19.2 for Actual Length
Represent as a fraction
--- (1)
Recall that:
Represent as a fraction
--- (2)
Equate (1) & (2)
Multiply through by 19.2m
Convert to centimeter
<em>Hence, the length of the scale model is 80 cm</em>
Answer:
3/8 cups
Step-by-step explanation:
Total fraction = 1/4 + 1/8
= 2/8 + 1/8
= 3/8
You'll want to work with the center-radius form of a circle equation for this. the center formula is <span>(x – h)</span>²<span> + (y – k)</span>²<span> = r</span>², where (h, k) is your center and r is your radius. plug in the information your circle gives you: A(-3, 12), radius = 5
(x + 3)² + (y - 12)² = (5)² ... simplify the right side
(x + 3)² + (y - 12)² = 25 ... from here, you need to foil both of your binomials to convert this to the "general form" that your answer choices are in.
(x + 3)² = (x + 3)(x + 3) = x² + 6x + 9
(y - 12)² = (y - 12)(y - 12) = <span>y² - 24y + 144
</span>
x² + 6x + 9 + y² - 24y + 144 = 25 ... combine like terms
x² + 6x + y² - 24y + 153 = 25 ... subtract 25
x² + 6x + y² - 24y + 128 = 0 is your equation. reorder it so that it's from the highest degree to the lowest: x² + y² + 6x - 24y + 128 = 0 is your result (C).
It’s the replacement of the Lena and width of the x+y
The most you can sell for each one is 9$ because its the greatest common factor
