Answer:
Distances travelled towards east from point A will be represented by positive integer i.e. +20 km.Distance travelled towards the west from point B will be represented by negative integer, i.e., —30 km.Final position of Rita from A= 20 km – 30 km = – 10 kmHence, the required position of Rita will be presented by a negative number, i.e., -10.
Step-by-step explanation:
[20 2/3]/3 can be rewritten as an improper fraction.
20 2/3 = 62/3. Now we divide 62/3 by 3, which is the same as multiplying by 1/3.
62/9 is the number of hours each day, or 6 8/9 hours. Almost 7 hours. And this makes sense, as 20 2/3 is almost 21 hours.
Answer:
11:
since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=<u>26</u>
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=<u>111</u>
