How do I write an inequality for 6x+8>2

Hatshy [7]

Answer:

The inequality is $x>-1$

Step-by-step explanation:

Given:

The inequality to solve is given as:

$6x+8>2$

Now, in order to solve it for 'x', we need to isolate 'x' on one side of the inequality.

<em>Adding -8 on both sides, we get:</em>

$6x+8-8>2-8\\\\6x>-6$

<em>Dividing both sides by 6, we get:</em>

$\frac{6x}{6}>\frac{-6}{6}\\\\x>-1$

Therefore, the inequality for 'x' is given as:

$x>-1$

So, 'x' include all the values that are greater than -1.

determine the radius of the cone ,if the voulime of the cone is 125 cm to the power of 3 and the height of the cone is 12cm. Rou

Salsk061 [2.6K]

For this case we have that by definition, the volume of a cone is given by:

$V = \frac {1} {3} * \pi * r ^ 2 * h$

Where:

r: It is the radius of the cone

h: It is the height of the cone

According to the statement data we have:

$h = 12 \ cm\\V = 125 \ cm ^ 3$

Substituting in the formula:

$125 = \frac {1} {3} * \pi * r ^ 2 * 12$

We cleared the radius:

$3 * 125 = \pi * r ^ 2 * 12\\\frac {3 * 125} {12 \pi} = r ^ 2\\9.9522 = r ^ 2\\r = \pm \sqrt {9.9522}$

We choose the positive value:

$r = 3.1547$

We round and we have that the radius of the cone is:

$r = 3.16 \ cm$

ANswer:

$r = 3.16 \ cm$

Fist lets find the % of people using boats
100%- (36+53+2)= 9%
then find the number of people of 9%
200= 100%
B=9%
100B=200x9
