56=8+(9-1)d
48=8d
d=6
t22=8+(22-1)6
T22=134
<h3>Answer:</h3>
<h3>Explanation:</h3>
You can try the choices to see which one works. The differences between an values double each time. They have the sequence 1, 2, 4, 8. So, you know that choices A) and D) do not work. They show the difference to be constant at 1 or 8. Since the differences are multiplied by 2, C) is a reasonable choice. Trying that, we find it describes the sequence perfectly:
a2 = 2·2 -1 = 3
a3 = 2·3 -1 = 5
a4 = 2·5 -1 = 9
a5 = 2·9 -1 = 17
___
Trying choice B on the last term, we have
... a5 = 3·a4 -3 = 3·9 -3 = <em>24 ≠ 17</em>
8x+1=x-6
7x+1=-6
7x=-7
X=-1
Y=x
Y=-1
If Allison scored 78.5 and Hannah scored 74.65 you’ll subtract 74.65 from 78.5 and get 3.85. That’s how many points more Allison scored
Answer:
3750 J
Step-by-step explanation:
We are given that
Total number of cartons=10
Height of loading dock from the side walk=1.5 m
Length of ramp=10 m
Mass of each carton=25 kg
We have to find the work done by the delivery man on the cartons to move them to the loading dock.
Work done=
Where M=Total mass of object
h=Height of object above the ground
g=Acceleration due to gravity=
Total mass of cartons=M=
h=1.5 m
Substitute the values then, we get
Work done=J
Hence, the total work done by the deliverman on the cartons to move them to the loading dock=3750J
