Answer:
$41.96
Step-by-step explanation:
30% of 59.95 is 17.99 (rounding to the nearest hundredth place since it was 17.985)
subtract 17.99 since it is the sale (30%)
59.95 - 17.99 = 41.96
the cd is worth $41.96 on sale for 30% off.
Answer:
3199
Step-by-step explanation:
3387 – 45 – 46 – 48 – 49 = 3199
Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
Step-by-step explanation:
In order for us to find the circumference, we need to find the radius from the given area by rearranging the area formula.
Now that we have the radius, we can find the circumference.
So, when given 113.1 in sq for the area, the circumference of the circle is 37.68 in.
B. The square root function is the quadratic function reflected across
the line y = x, with a limited domain.
