Hello,
Let a the first, b the second and c the third.
a+b+c=53
b=a/3
c=2a
==>a+a/3+2a=53
==>10a/3=53
==>a=15.9
c=2*a=2*15.9=31.8
b=a/3=15.9/3=5.3
Proof: a+b+c=15.9+5.3+31.8=53
The second number is 5.3
Answer:
5 1/4
Step-by-step explanation:
4 1/5 - 2 7/20 + 3 1/4
Common denominator = 20.
4 4/20 - 2 7/20 + 3 5/20
7 12/20 - 2 7/20 = 5 5/20 = 5 1/4
Step-by-step explanation:
Volume of a cylinder : πr^2*height.
Volume : 150cm^3
height : 7.2m
π =3.14
150 = 3.14*r*r*7.2
150=22.608*r*r
r^2= 150/22.608
=150/23cm^2
r=√6.5
r=2.569cm
r=2.6cm
We will use the following coordinates (4,4) and (5.5,3.5) these two are closest to the line.
Then we will do the following to find the gradient (slope)
(3.5-4)/(5.5-4) = - 1/3
rounded to 3 decimal places would give us -0.333
