Answer:

≤ and ≥ means bigger / smaller or even.

x≤23 means that x is either smaller than 23 or it is 23

x≥23 means that x is either bigger than 23 or it is 23

< and > means bigger / smaller

x<23 means that x is smaller than 23

x>23 means that x is bigger than 23

hope it helps (:

The cylinder below has a volume of 536.94 cubic inches. What is the radius of the cylinder? (Use 3.14 for π.)

Anestetic [448]

We have been given volume of the cylinder which is 536.94 cubic inches. Now question says to find the radius of the cylinder.

Then we need to use formula of volume of cylinder which is given by :

$Volume = \pi r^2 h$

We see that there are three unknown values in the formula: {volume, radius-r, height-h}

So to find any one of them we must know other two values.

Volume is given but height is missing. So just for explanation i'm going to use height of the cylinder h= 19 inches

Now plug the value of volume and height in above formula

$536.94 = \pi r^2 *19$

$536.94 = 3.14 r^2 *19$

$536.94 = 59.66r^2$

$\frac{536.94}{59.66} =r^2$

$9=r^2$

take square root of both sides

3=r

Hence radius of the cylinder is 3 inches.

What graph represents −3x+1≤10

nalin [4]

The solution of the inequality is x ≥ -3 and the graph is shown below

<h3>Graph of inequalities </h3>

From the question, we are to determine the graph that represents the given inequality

The given inequality is

−3x + 1 ≤ 10

First, we will solve the inequality

−3x + 1 ≤ 10

Subtract 1 from both sides

−3x +1 -1 ≤ 10 - 1

−3x ≤ 9

Divide both sides by -3 and<u> flip the sign</u>

x ≥ -3

The graph of the inequality is shown below

A pharmaceutical company sells bottles of 500 calcium tablets in two dosages: 250 milligram and 500 milligram. Last month, the c

Svetach [21]

X = 250 mg tabs
y = 500 mg tabs

2200x + 1800y = 39200....multiply by -1
2200x + 2200y = 44000
--------------------------------
-2200x - 1800y = - 39200 (result of multiplying by -1)
2200x + 2200y = 44000
--------------------------------add
400y = 4800
y = 4800/400
y = 12...... the 500 mg tabs (y) costs $ 12 per bottle

2200x + 2200y = 44000
2200x + 2200(12) = 44000
2200x + 26400 = 44000
2200x = 44000 - 26400
2200x = 17600
x = 17600/2200
x = 8 <== the 250 mg tabs (x) costs $ 8 per bottle
