If you draw a rectangle divided up into eight even parts, and label them each as 1/8, then you can show your work for how you double it. You do this by "coloring" one in, and then doing the same for a second piece (but color that one in a different way). You can visually double an eighth in that way.
Or, you can simply multiply by 2 to double 1/8:
1/8x2/1=2/8
Answer:
The average rate of change
At t = 1
at t=3
Step-by-step explanation:
<u><em>Step(I)</em></u>:-
The given function h(t) = 3+70t - 16t²
The 
70 - 32 t = 0
⇒ 70 = 32 t
⇒ 
<em>Step(ii</em>):-
The average rate of change in h(t) between t = 1 second and t = 3 second
At t = 1
At t = 3

Answer:
He average for this semester so far is 81 points.
Step-by-step explanation:
Since his score is 10% lower this semester than last semester, then he present score is 100% from the prior semester minus 10%, which equals to 90% of the previous semester. In order to calculate that percentage we can use a rule of three as shown below:
90 points -> 100%
x points -> 90%
100*x = 90*90
x = 8100/100 = 81
He average for this semester so far is 81 points.
Answer:
d. 12 cm
Step-by-step explanation:
Corresponding sides have the given ratio:
EG/AC = 3/2 = EG/8 . . . . . . . fill in for AC
EG = 8(3/2) = 12 . . . cm . . . . . . . multiply by 8
