Answer:55.227
Step-by-step explanation:
Given data
mass =13lb
spring stretches by =4.5in=0.375 ft
g=
Now Spring constant K
mg=kx
k=
For critical damping
and
substituting values
c=55.227 lb.sec/ft
Answer:
x + y = 10
Step-by-step explanation:
The mean is calculated as
mean = , thus
= 5 ( multiply both sides by 6 )
20 + x + y = 30 ( subtract 20 from both sides )
x + y = 10
Answer:
There are 2 red pens in each pack
There are 3 blue pens in each pack
Step-by-step explanation:
<u> we know that</u>
270=2*3^{3} *5
180=2^{2}*3^{2}*5
<u>Find the Greatest Common Factor (GCF)</u>
The GCF is equal to------> 2*3^{2}*5=90
the greatest number of packs she can make is 90
Find the number of red pens in each pack 180/90=2 red pens
Divide the total number of red pens by the total number of packs
Find the number of blue pens in each pack 270/90=3 blue pens
Divide the total number of blue pens by the total number of packs
