The inequality that represents the sentence "two more than a number is less than 14" is [tex]n+2 < 14[/tex].

Let the number be n

2 more than number = n+2

Inequality is the relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

It is given that,

Two more than a number is less than 14

This means, [tex]n+2 < 14[/tex]

Therefore, the inequality that represents the sentence "two more than a number is less than 14" is [tex]n+2 < 14[/tex].

The polynomial is prime because the provided polynomial can not be factored shown in the X-method chart.

X-method is the method to find the factors of the polynomial equation.

An x-method chart shows the product a c at the top of x and b at the bottom of x.

Above the chart is the expression,

[tex]ax^2+bx+c[/tex]

The given polynomial in the problem is,

[tex]x^2 +8x - 6[/tex]

Let's check if the factors of polynomial. To find the factor, we need, to find the two number whose sum or different is 8 and the product is 6 (6 × 1).

As there is no number which gives has the sum or different is 8 and the product is 6 (6 × 1). Thus, the above polynomial can not be factored. Thus this polynomial is prime.

Thus, the polynomial is prime because the provided polynomial can not be factored, shown in the X-method chart.

Answer:

x=21

Step-by-step explanation:

4x+12=96

subtract 12 from both sides

4x=84

divide both sides by 4

x=21

Answer:

x = 21

Step-by-step explanation:

to solve:

1. subtract 12 from both sides:

4x=12=96

    -12 -12

2. This gives you 4x=84. Then divide both sides by 4:

[tex]\frac{4x}{4}[/tex][tex]=\frac{84}{4}[/tex]

4x/4 = x

84/4 = 21

So, you get x = 21

Answer:

62

Step-by-step explanation:

step 1: find the height of half the yellow coloured triangle (right angled triangle). remember that the angle formed at the center is always 36° for a pentagon.

tan36° = opposite/ adjacent

tan36° = 3/h (h for height)

h × ( tan36°) = 3

h = 3 / tan36°

h = 4.13

step 2: calculate area of the right angled triangle

Area = 1/2 × b × h

= 1/2 × 3 × 4.13

= 6.195

step 3: calculate the area of a Pentagon

a Pentagon can be divided into ten right angled

triangle

6.195 × 10

total area = 61.95

rounded off = 62

14.23n - 15 = 41.92

Explanation :

In mathematics "n" denotes any non-negative integer

as in this case "n" denotes the number of necklaces Christine bought

If 1 necklace costs $14.23

n no. of necklaces costs $14.23 × n = 14.23n

She used a coupon for $15 off

so the total amount spent

= the cost for n no. of necklace – $15

= 14.23n – 15

that's technically how the equation given in the question has been derived

total amount spent = $41.92 ( stated in question )

previously we derived an equation for the total amount spent which is = 14.23n – 15

14.23n - 15 = 41.92

14.23n = 41.92 + 15

14.23n = 56.92

n = 56.92 / 14.23

n = 4

no. of necklaces bought = n = 4 necklaces

Answer:

The pool is 5 ft. deep.

Step-by-step explanation:

If he wants a pool that 500 cubic feet and the base is 100, simply do 500/100

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{-4})\qquad \qquad \stackrel{slope}{m}\implies -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-4)}=\stackrel{m}{-3}(x-\stackrel{x_1}{1}) \\\\\\ y+4=-3x+3\implies y=-3x-1[/tex]

Answer:

$57

Step-by-step explanation:

I'll assume the pool's dimensions are 18 x 40 x 6.

The total volume is (18 x 40 x 6) = 4320 ft^3.

Use the conversion factor (2.64 gallons/1 ft^3) to find the gallons of water in a full pool.  Full pool, cool.

Water (gal) = (4320 ft^3)*(2.64gallons/ft^3) = 11,405 gallons

At $0.005/gal, this would cost (11,405 gallons)*($0.005/gal) = $57.02

$57 to the nearest dollar.

The difference in the price per bag for 150 bags versus 50 bags is $0.15 per bag.

If 150 bags on the x axis is traced to the y axis, the price of the bag is $38.

If 50 bags on the x axis is traced to the y axis, the price of the bag is $20.

Price per bag:

150 bags = 38 / 150 = $0.25

50 bags = $20 / 50 = $0.4

The difference = $0.4  $0.25 = $0.15

Depends on the pool you are pulling them from.

There are currently 11 different denomination accessible.

That would be 1 out of 11.

But considering that 4 of those bills are uncommon, the odds become 1 out of 7

Answer:

Volume for a cylinder in this case is

V=˜ πr^2h

So R being radius

H being height

V being volume.

We know the volume is 250π

The height is given in the diagram which is 10.

Plug in the infromation into the formula.

250π = πr^2*10

Simplify and solve for r (radius).

Let’s divide by π on both sides

250 = r^2 * 10

Divide by 10 to get rid of 10

25 = r^2

√25 = r

√25 = 5

The radius is 5
