Lee and Fred are elementary school teachers. Fred works for a charter school in Pacific Palisades, California, where class size reduction is a goal for 2013. Lee works for a non charter axhool where funds do not allow for class size reduction policies. Lee’s fifth-grade class has 1.5 times as many students as Fred.

a) If there are total 55 students, how many students does Fred have? (Round your answers to the nearst whole number.)

b) If there are total 55 students, how many students does Lee have? ( Round your answers to the nearst whole number.)

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

2,600 divided by 80 = 32.5

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
