Answer:
Participant A
Step-by-step explanation:
Rate: jumping jacks per minute
Rate of A: 120jjs / 10mins = 12 jumping jacks per minute
Rate of B: 140jjs / 14mins = 10 jumping jacks per minute
Option A, x < 0
When looking at line graphs, it's relatively easy to figure out how they work.
Start by locating where the point is. In this case, the point is on 0. Now, is the point hollow? If it is, then you know that the inequality is either < or > (if it's hollow, it means that the integer isn't included). However, if the circle's filled in, you know that it's either ≥ or ≤ (if the circle's filled in, the integer is included)
Now, check to see which way the line goes. Does the number get smaller or bigger as you go across the line? If the number gets bigger, then x > 0. If the number gets smaller, then x < 0.
-T.B.
The area of a circle is calculated as pi*(r^2). Given a diameter of 26 cm, the radius is half the diameter, which is 26/2 = 13 cm.
Therefore the area is pi*(13^2) = 169 pi.
Another alternative formula for the area is pi*(d^2 / 4). Substituting d = 26 would give pi*(26^2 / 4) = pi*(676/4) = 169 pi, which is the same answer.
So the correct answer is C.
