Answer:
1/4 hr longer
Step-by-step explanation:
There are 8 triangles in this circle
An entire circle = 360 degrees
360/8=45
So I think the answer should be 45%

Answer:
$3103.6
Step-by-step explanation:
Given data
Total sales= $26,480
Returns and Allowances=$1250
Commission = 7%
Let us find the amount in commission earned
=7/100*26,480
=0.07*26480
=$1853.6
Hence the gross earnings
=1853.6+1250
=$3103.6
Answer:
centre = (2, - 1), radius = 6
Step-by-step explanation:
Rearrange the equation by placing the x and y terms together and adding 31 to both sides
Given
x² + y² - 4x + 2y - 31 = 0, then
x² - 4x + y² + 2y = 31
Use the method of completing the square
add ( half the coefficient of the x/y term )² to both sides
x² + 2(- 2)x + 4 + y² + 2(1)y + 1 = 31 + 4 + 1
(x - 2)² + (y + 1)² = 36
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
compare to (x - 2)² + (y + 1)² = 36, then
centre = (2, - 1) and r =
= 6
