How do you simplify 2i<6u ?

marusya05 [52]

In simplifying inequalities, there are a few things that you have to remember. Here are some:

<span>Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
But these things will change direction of the inequality:<span>Don't multiply or divide by a variable (unless you know it is always positive or always negative)

We simplify as follows:
2i/2<6u/2
i<3u</span></span>

AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Llana [10]

Formula for the volume of cone is $\frac{1}{3} \pi r^2h$

Where r= radius of the cone

h = height of the cone

The value of pi is 3.14

Given volume of larger cone is 131 cm^3

Volume of larger cone = $\frac{1}{3} \pi r^2h$

131 = $\frac{1}{3} \pi 5^2h$

Solve for h

131 = 26.1667 *h

So h= 5 cm

The height of bigger cone = 5cm

Now we find the volume of smaller cone

Two cones similar so the sides are in proportional

$\frac{radius(small)}{radius(large)}= \frac{height(small)}{height(large)}$

$\frac{2}{5} =\frac{ height of small}{5}$

Height of smaller cone = 2cm

volume of smaller cone = $\frac{1}{3} \pi 2^2*2$

= 8.38cm^3
