What 8?

There is no 8 in the problem.

The answer is not a specific value for n.

3n < 18

Divide both sides by 3.

3n/3 < 18/3

n < 6

ANSWER: n < 6

What does the answer mean?

It means that n must be less than 6 to make the original inequality a true statement.

====================================================

Explanation:

One general template of exponential functions is

f(x) = a*(b)^x

The 'a' is the initial amount, which in this case is a = 300

----------------------

Extra info:

The b is the base of the exponential, which is b = 1.16

The value of b is helpful to determine if you have exponential growth or decay, and how much of either. Because b = 1.16 is greater than 1, it indicates exponential growth. The rate of growth is found by solving 1+r = 1.16 to get r = 0.16, which leads to 16% growth.

Answer:

98

Step-by-step explanation:

It would be the same amount because when the lines are parallel, the corresponding angles will also be the same.  

We can tell the difference between the two types of angles (Supplementary and complementary) 98 and 82 would be the two types of angles.

So, the angle measure would be 98.

Answer:

Costo final= $412.38

Step-by-step explanation:

Dada la siguiente información:

Costo inicial= $355.5

Recargo de la tarjeta= 16% = 0.16

Para calcular el costo final que debe pagar Silvia, debemos usar la siguiente información:

Costo final= costo inicial*(1 + recargo)

Costo final= 355.5*1.16

Costo final= $412.38

Answer:

3x, 2x + 5, and x - 3

Step-by-step explanation:

Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.

Our equation is:

6x³ - 3x² - 45x

First, we can factor out an x:

x (6x² - 3x - 45)

From here, we can see that by factoring out a 3:

3x (2x² - x - 15)

Now, after completing the square and factoring:

3x (2x + 5) (x - 3)

These are our three expressions.

Answer:

(-2, 3) = domain -2 = range 3

(3, -2) = domain 3 = range -2

(1, 3), = domain 1 = range 3

Answer:

28 in^2

Step-by-step explanation:

Given,

Height of the parallelogram = 14 in

Base of the parallelogram = 2 in

Therefore, area of the parallelogram = base × height

= 2 in × 14 in

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 28 {in}^{2} (ans)[/tex]

Answer:

y=10

x=10

Step-by-step explanation:

THis is isosceles triangle

180-90-45=45

used pyagorous therum thingy

10over2= square root of 200

so c2=asquare X b squared in this case x=y

so 200/2 = 100

x=100square

y=100 square

simplify = 10

Answer:

54.22 mm

Step-by-step explanation:

Find the circumference of the circle and then divide it by 2.

We start with the formula for the circumference for the circle:

C = 2πr

To find r, divide 22 by 2:

22/2=11

Now find the cicumference:

C = 2πr = 2(3.14)(11) = 108.46 mm

NOW, to find the perimeter of the semicircle, divide the circumference by 2:

108.46/2 = 54.22 mm

Answer:

9x² + y² + 64 - 6xy - 16y - 48x

= 9x² - 6xy - 48x + y² - 16y + 64

= 9x² - 6x(y - 8) + y² - 2.8y + 8²

= (3x)² - 6x(y - 8) + (y - 8)²

= [3x - (y - 8)]²

= (3x - y + 8)²

Answer:

18.34times

Step-by-step explanation:

the explanation is given in the pictures...

The road roller is turning at the rate of [tex]18.3rev/minute[/tex]

To get our answer, first note that

[tex]speed=\dfrac{distance}{time}[/tex]

since the distance travelled by the road roller can be gotten by

[tex]distance= circumference\times revolutions[/tex]

our speed formula can be expressed as

[tex]speed=\dfrac{circumference\times revolutions}{time}[/tex]

making the number of revolutions the subject of the formula, we get

[tex]revolutions=\dfrac{speed \times time}{circumference}[/tex]

carrying out the following substitutions

[tex]speed=3miles/hour=\frac{3\times63360}{60}inches/minute=3168inches/minute\\time=1minute\\circumference=2\times3.14\times\frac{55}{2}=172.7inches[/tex]

we can now calculate the number of revolutions

[tex]revolutions=\dfrac{speed\times time}{circumference}\\\\=\dfrac{3168\times 1}{172.7}\approx18.3rev/minute\text{ (to the nearest tenth)}\\\\[/tex]
