To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.

Answer:
Option (b) is correct.
The solution of the quadratic equation
is -7 and 3
Step-by-step explanation:
Consider the given quadratic equation
This can be rewritten as,
We can solve the quadratic equation using middle term splitting method,
4x can be written as 7x-3x , we get,
Taking terms common, we get,
Thus,
Thus, we get (x-3)= 0 or (x+7)= 0
this gives x = 3 or x = -7
Thus, the solution of the quadratic equation
is -7 and 3
Answer:
167.467mm^3
Step-by-step explanation:
Volume of cone:1/3hpir^2
1/3(10)(pi)(4)^2
=160/3(pi)
(Pi=3.14)
160/3pi=167.467mm^3
Which part of the question?
Ratio of their
x = 27*36 / 8 volumes = 2^3 : 3^3 or 8:27
so 8/27 = 36/x
x = 27*36 / 8 = 121.8 cubic units
