Answer:
$140.90
Step-by-step explanation:
**22% = 0.22**
X = 109.90 / (1 - 0.22)
X = 109.90 / 0.78
X = 140.90
Answer:
$725.95
Step-by-step explanation:
129.95 times 5 is 649.75
649.75 plus 76.20 = 725.95
Answer:
- 5/2
Step-by-step explanation:
Arrange this line equation into y = mx + b form m = slope
y = 2/5x + 12/5
then perpindicular line = - 1/m = - 1/ (2/5) = - 5/2
Answer:
Center: (1, 5)
Radius: r = 5
Step-by-step explanation:
Step 1: Rewrite equation
x² - 2x + y² - 10y = -1
Step 2: Complete the Square (x2)
x² - 2x + 1 + y² -10y + 25 = -1 + 1 + 25
(x - 1)² + (y - 5)² = 25
Step 3: Find answers
Center = (h, k)
(1, 5) as Center
Radius = <em>r</em>
r² = 25
r = 5
Answer:
1.
Original square side: s
Area = s^2
Modified square:
Length = 1.3s
Width = 0.82s
Area = 1.3s * 0.82s = 1.066s^2
(1.066 - 1)/1 * 100% = 6.6%
The area increases by 6.6%
