Im pretty sure
a = 65
b= 80
Answer:
C. 8.0
Step-by-step explanation:
The mechanical advantage is got from dividing the circumference of the shaft by the pitch of the screw.
Therefore, the circumference= 2πr
=2×π×2.3mm
=14.45mm
Mechanical advantage=14.45mm/1.8mm
=8.03
At least 15% of the players in the shipment will have no defects
Answer:
<em>5,9,13,17,21</em>
Step-by-step explanation:
We can the values in "n"
a(1)=4(1)+1
a(1)=5
a(2)=4(2)+1
a(2)=9
a(3)=4(3)+1
a(3)=13
a(4)=4(4)+1
a(4)=17
a(5)=4(5)+1
a(5)=21
As you can see, each value consecutively increases by 4, this is also known as the common difference (d).
If $26 represents the cost of the 5 used CDs, than your formula would be "26+4x" ,x being the amount of extra CDs you purchase.
The number CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $26 group.
26+4(6-5)
26+4(1)
26+4
30
6 CDs would cost $30
