Hey there! :)

Answer:

Step-by-step explanation:

To find the solution to the inequality, we can begin by solving for 'x':

2x + 1 ≥ 3

Subtract 1 from both sides:

2x ≥ 2

Divide both sides by 2:

x ≥ 1.

This means that the graph must contain all values of x greater or equal to one. The only number line that shows solutions greater than 1 is B.

Round your answer to the nearest tenth if necessary. Use 3.14 for .

harina [27]

Answer:

$\boxed{\rm \: Volume_{(Drum)} = 5024 \: in {}^{3} }$

Step-by-step explanation:

Given :

Diameter of a drum = 20 inches
Deep ( height ) of the drum = 16 inches
π = 3.14

To Find:

The volume of the drum.

Solution:

We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.

$\boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}$

Where,

r = radius
h = height (deep)
π = 3.14

The value of radius ain't given,but the diameter is given.We can use the formulae of radius.

$\rm \: Radius = D/2$

D = diameter

Substitute the value of diameter:

$\rm \: Radius = \cfrac{20}{2} = 10$

Hence,the radius is 10.

So we could now use the formulae of the volume of cylinder:

$\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h$

π = 3.14
r =10 in
h = 16 in

<em>[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]</em>

$\rm \: Volume_{(Drum)} = \pi(10) {}^{2} (16)$

$\rm \: Volume_{(Drum)} =\pi100(16)$

$\rm \: Volume_{(Drum)} = 1600\pi$

$\rm \: Volume_{(Drum)} = 1600 \times 3.14$

$\boxed{\rm \: Volume_{(Cylinder)} = 5024 \: in {}^{3}}$

<u>Hence, we can conclude that:</u>

The volume of this drum is 5024 in^3.

3 + x < 7 possible sloution for this

krok68 [10]

Answer: x<4

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

x+3<7

Step 2: Subtract 3 from both sides.

x+3−3<7−3

x<4
