Answer

Find out the what is the value of x when y = 8 .

To prove

As given

The variables y and x have a proportional relationship.

y \propto x

y = kx

Where k is the constant of proportionality.

As y = 5 when x = 4

Put in the above

5 = 4k

k = \frac{5}{4}

Now find out the value of x , when y = 8

8 = \frac{5\times x}{4}

x = \frac{8\times 4}{5}

x= 6.5

Therefore when y = 8 than x = 6.4

Multiply. Express your answer in simplest form. 9 1/6 × 1 1/11
Sati [7]

Answer:

10

Step-by-step explanation:

First convert the fractions.

9 1/6 to 55/6  and 1 1/11 to 12/11

With these fractions, you can cross out 11 and 6.

55   times    12             5   ×    2

6                   11              1   ×    1

This equals 10/1 or 10

The two cylinders are similar. If the ratio of their surface areas is 9/1.44, find the volume of each cylinder. Round your answe
WITCHER [35]
R1² π : r2² π = 9 : 1.44
r1 : r 2 = 3 : 1.2
r2 = 1.2 · r1  / 3
r 2 = 0.4 · r1
If the two cylinders are similar than also: h 2 = 0.4 · h 2
V 1 = r1²   · π  · h1
V 2 = ( 0.4 r1)² π · 0.4 · h1 = 0.064 r1² · π · h1
V 2 ( small cylinder )= 0.064 · V 1 ( large cylinder ) 
851.22 m³= 13.300.25 m³ · 0.064

5x-1=15x-101 equation
sladkih [1.3K]
5x - 1 = 15x - 101
101 - 1 = 15x - 5x
100 = 10x
100/10 = x
x = 10

How this has been solved is by bringing the equations with (x) to one side and solving them and solving the other numbers on the other side..
