-- IF all 90 pieces in the bag are oranges or apples,
THEN there are 9 apples and 81 oranges.
-- You didn't specify that, so it's possible that there could be
2 apples, 18 oranges, and 70 kumquats or sabra pears.
<span>perimeter of a semicircle is calculated as follows;
diameter = 35 inches
circumference of circle - 2</span>πr
<span>r - radius -
r = diameter / 2 = 35 /2 = 17.5 inches
circumference = 2 x 3.14 x 17.5 = 109.9 inches
circumference is perimeter of whole circle. we need to find the circumference for half the circle.
therefore perimeter for the curved line = 109.9 / 2 = 54.95 inches
perimeter of half circle = diameter + curved line perimeter = 35 + 54.95 = 89.95 inches
answer is B. 89.95 in.</span>
Answer:
5(n+1)/((n+1)(n+3))
5/(n+3) is a answer
Step-by-step explanation:
(n+1)/(n+1)=1
So basically you can determine which of them are functions by using the vertical line test. If you can draw any vertical line that intersects more than one point of the relationship, then it is not a function.
I'm not complete sure about the discrete one but, hopefully it's right :).
