There are 3 because 12 divided by 4 is 3.
Answer:
1.75 hours
Step-by-step explanation:
Time for day 1 : 4.5 hrs
Time for day 2: (4.5 ×2.5)
Time for day 3: let it be denoted by a variable ,say T.
Total Time= 17.5
(Time for day 1 ) + (Time for day 2) +(Time for day 3) =17.5
4.5 + (4.5×2.5) + T = 17.5
4.5+11.25+T =17.5
15.75+T=17.5
T=17.5-15.75
T= 1.75

Answer:
3
Step-by-step explanation:
A ( 2, 2 )
( x1, y1 ) = ( 2, 2 )
Here,
x1 = y1 = 2
B ( - 2, - 2 )
( x2, y2 ) = ( - 2, - 2 )
Here,
x2 = y2 = - 2
Distance formula : -
d = √ ( x2 - x1 )² + ( y2 - y1 )²
AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²
= √ ( - 2 )² + ( - 2 )²
= √ 4 + 4
AB = √8
The value of √8 is 2.828.
Roundoff to nearest 10 is 3.
