Nick and Liz have decided to move from the city to the suburbs. This means that they will have to make the essential purchase of
sineoko [7]

Answer:

$=19400

Step-by-step explanation:

Average prices= $18,500

Number of prices that were quoted= 7

Expected sum that produces this mean= 7*18,500=$129,500

Sum of quoted prices=

$(15,500+ 18,800+ 16,900+ 19,900+18,000+21,000) =$110100

Next price to be quoted will be ;

$129,500-$110,100

$=19400

Jon ran around a track that was 1/8 of a mile long,he ran around the track 24 times,how many miles did Jon run
Sonbull [250]
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

Ex What factors do 12 and 24 have in common? 1, 2, 3, 4, 6, 12​
mestny [16]

Answer:

1, 2, 3, 4, 6, 12

Step-by-step explanation:

All these numbers are common factors of 12 and 24 because you can divide each one by all of the factors

ex. 12/3 = 4

24/3 = 8

if you don't get a decimal answer, then it is a factor of these numbers

Which of the following circles have their centers on the x-axis? Check all that apply.
Alexeev081 [22]

Answer: Option A and Option D

Step-by-step explanation:

By definition the general equation of a circle has the following form

(x-h)^2+ (y-k)^2=r^2

Where r is the radius and the point (h, k) is the center of the circle

All points that are on the x axis have the following form:

(h, 0)

Therefore all the circles that have their centers on the x axis will have a value of k = 0.

Identify among the options all those equations that have a value of k = 0

The circles that have their center on the x axis are option A and option D
