An ordinal variable is a categorical variable for which the possible values are ordered. Please mark me as brainliest.
Hi there
So, if the track is 1/8 of a mile, let's call every lap a "one-eighth mile" run. We know John ran 24 laps, or that he ran 24 "one-eighth miles," just consecutive, one right after another. Let's stop worrying about rates or tricks or math for a second, and just ask: how many real miles is 24 "one-eighth" miles? We know it's less than 24---a lot less, since you have to go around 8 times just to get to 1 mile. Well wait, if we go around 8 times, we get 1 mile. That means if we go around 28, or 16 times, we get 2 miles; And let's just think to the next full mile---if we go 38, or 24 times, we get 3 miles. He did go around 24 times, so he must have run 3 miles on a 1/8 track.
Division and multiplication are inverses of each other. So we solved this by looking for an intuition for how many full miles corresponded to how many laps, with a bunch of steps of multiplication. But you can cut right to the chase and solve it faster with division---24 laps * 1 mile per 8 laps, means:
total distance = 24 Lap (1 mi / 8 Lap) total distance = 24/8 total distance = 3
Answer
I attach the image of the circle in the picture below
Circumference larger circle = 62.831 in
Step-by-step explanation:
The perimeter of a circle is defined as
P = 2* pi* r
where
r corresponds to the radius of the circle.
In this case,
r = d/2 = 3 in
The perimeter of the smaller circle results
P1 = 2*(3.1416)*(3 in) = 18.8495 in
The circumference of the smaller circle is 30% of the circumference of the larger circle, so
P1 = 0.3* P2
P2 = 18.8495 in / 0.3 = 20
= 62.831 in
Answer:
-6
Step-by-step explanation:
6a - 5 = 7 + 8a
6a - 8a = 7 + 5
-2a = 12
a = 12/-2
a = -6
Hope it helps:)
