Answer:
3 days
Step-by-step explanation:
First, let's convert 400 meters to km (kilometers):
To find km from m we divide the meters by 1000:
400/1000 = 0.4
Therefore, there are 0.4 km in 1 meter.
Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:
(10)(0.4) = 4
Kali runs 4 kilometers every day
Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4
12/4 = 3
It will take Kali 3 days to run a total of 12 kilometers.

Question is Incomplete, Complete question is given below.
School started at 8:05 a.m and ended at 2:40 p.m. the work below shows Erica's calculation of the length of the school day
Which two errors did Erica make
A.She subtracted instead of adding the times
B.She subtracted the end time from the start time
C.She did not regroup on hours for 60 minutes to subtract the minutes
D.she did not account for a.m. and p.m. in the start and end times.
E.see switch to hours and minutes in both the start and end times
Answer:
B. She subtracted the end time from the start time and
D. She did not account for a.m. and p.m. in the start and end times.
Step-by-step explanation:
The school started at 8:05 a.m. and ended at 2:40 p.m.
And the length of the school day is calculated by Erica and it is shown in the attached photo.
See the attached photo.
Erica has done two errors which are
B. She subtracted the end time from the start time and
D. She did not account for a.m. and p.m. in the start and end times.
QRST is a rhombus
Let’s look at the diagonals
Length QS = sr(4^2 + 0) = 4
Length RT = sr(0 + 6^2) = 6
This means it cannot be a square or rectangle as they both have equal length diagonals.
QS is horizontal (y values same)
RT is horizontal (x values same)
This means it is a rhombus because diagonals are perpendicular and different lengths.
Squares have perpendicular diagonals of same length
Rectangles have diagonals of same length but not perpendicular
