Answer:
Formula to the area of a parallelogram is A = base x height
A = 14.3 x 11.4
A = 163.02in^2
(you got it right!)
Why yes it is right. good work
Step-by-step explanation:
A)
Janet's took 34.56 seconds to cover 50m freestyle swim.
In words it could be said as: thirty four and fifty six hundredths.
B)
Race # Time (in sec.) time( after roundoff to nearest integer)
<em> 1 34.56 35</em>
<em> 2 35 35</em>
<em> 3 34.8 35</em>
4 34.137 34
5 33.92 34
Hence, the first 3 race times were equal after rounding off to nearest integer.
C)
on arranging the time of Janet's from fastest to slowest we get the table as:
Race # Time( in sec.)
5 33.92
4 34.137
1 34.56
3 34.8
2 35
since, after decimal we arrange the numbers in order same as we do for the natural numbers.
as in race #5 '33' is the smallest among all hence we keep it in first place.
for race 4,1 and 3 we have the same digit before decimals so now we have to look for the number after decimals.
D)
Janet's time in race #4 was: 34.137 sec.
But Grace was 1.8 seconds faster than Janet.
Hence, Grace time=34.137-1.8=32.337 sec.
Answer:
Infinite many solutions
Meaning there is more than one solution
Hope this helps!
Let me know if this is right.
Answer:
10,000
Step-by-step explanation:
We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.
1 m = 100 cm
10 m = 1000 cm
40 m = 4000 cm
area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2
area of tile = s^2 = (20 cm)^2 = 400 cm^2
number of tiles = 4,000,000/400 = 10,000
Answer: 10,000 tiles
