Answer:

22 students

Step-by-step explanation:

Given,

Total number of students = 40,

∵ Number of students who play viola = \frac{1}{4} of the total students

= \frac{1}{4}\times 40

= 10

Also, number of students who play cello = \frac{1}{5} of the total students

= \frac{1}{5}\times 40

= 8

So, the remaining students = total students - students who play viola - students who play cello

= 40 - 10 - 8

= 22

Hence, 22 students play violin.

22 play violin.
1/5 * 40 = 8
1/4 * 40 = 10
8+10=18
40-18=22

22!

All of these #'s are not less then 4.1 and also not greater then 4.2...they are between the 2 numbers

An airplane is flying between two towns at an altitude of 8km. One town is to the west of the plane and the other is to the east
prohojiy [21]
So this can be solve by solving the distance of the plane and the town to the west and also the distance of the plane to the town to the east.  
So the town with an angle of depression of 34 degrees
Let x be the distance of the plane and town  
Cos 34 = x / 8
x = 8 cos 34
x = 6.63 km  
So the town with an angle of depression of 49 degrees
Let y be the distance of the plane and town  
Cos 49 = y / 8
y = 8 cos 49
y = 5.25 km  
<span>so the distance of the towns is 5.25 + 6.63 = 11.88 km</span>

slamgirl [31]

Answer:

7.5632 *10^{4}

Step-by-step explanation:The simplification

1+1×80+5-23+456×47+56784-2647

=1+80+5−23+(456)(47)+56784−2647

=81+5−23+(456)(47)+56784−2647

=86−23+(456)(47)+56784−2647

=63+(456)(47)+56784−2647

=63+21432+56784−2647

=21495+56784−2647

=78279−2647

=75632

Converting 75632 into standard form 7.5632 *10^{4}
