Answer:
3 feet per second
Step-by-step explanation:
If the time is multiplied by 2, the inverse relationship tells you the speed is multiplied by 1/2.
(1/2)(6 ft/s) = 3 ft/s
The swimmer's average speed is 3 ft/s.
They are as a result of the side angle side postulate. there is a vertical angle in the center, with a congruent side, and an equal angle (SAS)
Answer: 
Step-by-step explanation:
To find the circumference of a circle, you can use 
. You can set this equal to 21 (feet). The equation to solve at this point would be 
.
Answer:
-9
Step-by-step explanation:
If x varies directly with y, we can write an equation like: x = ky, where k is some constant. We want to solve for k first, so let's use the given numbers of y = 12 and x = 4:
x = ky
4 = 12k
k = 1/3
Now, our equation looks like this: x = (1/3)y. We want to find the value of y when x = -3, so plug -3 in for x:
x = (1/3)y
-3 = (1/3)y
y = -9
Thus, the answer is -9.
Hope this helps!
