Answer:
Division is not commutative because 25÷5 does not equal 5÷25
Step-by-step explanation:
250/360 = x/60
x = 41.7 cm
This is because when the whole circle is 250 cm (angle is 360 degrees), 60 degrees means that the arc is 41.7 cm.
Answer:
The center is at (-3, -2) and the radius = 1.
Step-by-step explanation:
We can do this by converting the given equation to standard form.
x^2+6x+y^2+4y+12=0
x^2+6x+y^2+4y = -12
Completing the square on the x and y terms:
(x + 3)^2 - 9 + (y + 2)^2 - 4 = -12
(x + 3)^2 + ( y + 2)^2 = -12 + 9 + 4
(x + 3)^2 + ( y + 2)^2 = 1
So the center is (-3, -2) and the radius = 1.
Answer:
it is c because i took test review
Step-by-step explanation:
The answer is at the bottom.
3 times 4/5 = 3/1 times 4/5
so you get 12/5
the question says as the product of a whole number and unit fraction
so it is 2 2/5.
the answer is 2 2/5
