Step-by-step explanation:

"Evaluate" means to substitute given values (numbers) for the variables and then determine the value of the expression using the Order of Operations.

The value of the expression is 19.

Answer:

C

Step-by-step explanation:

[tex](6.2)(4.3) = 26.66[/tex], so [tex]26.66 \leq 6.2n[/tex] is true.

26.66 ≤ 6. 2n

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

Explanation:

Let's replace n with 4.3 in choice A

3n < 12.9

3*4.3 < 12.9

12.9 < 12.9

The last inequality mentioned is false. No number is smaller than itself. So the original inequality is false when n = 4.3

We can rule out choice A.

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

Let's try choice B

5n > 21.7

5*4.3 > 21.7

21.5 > 21.7

This is false as well. You can think of it like saying 215 > 217 is false.

We can rule out choice B.

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

Now onto choice C

26.66 ≤ 6.2n

26.66 ≤ 6.2*4.3

26.66 ≤ 26.66

This is true. The "or equal to" portion is the reason why. Without this, then we'd have a repeat scenario of choice A earlier.

This is why choice C is the final answer.

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

We could stop since we found the answer by now. However, for the sake of completeness, let's look at choice D.

31 ≥ 7. 4n​

31 ≥ 7. 4*4.3

31 ≥ 31.82

which is false because it should be the other way around and it should be 31 ≤ 31.82 or at the very least 31 < 31.82

We can rule out choice D as well.

Answer:

The correct answer is 0.94147

Step-by-step explanation:

Let A denote the event that the podiatrist finds the first person with an ingrown toenail.

And (1 - A) denote the event that the podiatrist does not find the ingrown toenail.

While examining seven people, the podiatrist can find the very first person to have an ingrown toenail. Similarly he can find the second patient to have the ingrown toenail. Going in this way the probability of the first person to have an ingrown toenail is given by:

= A + (1 - A) × A + (1 - A) × (1 - A) × A + (1 - A) × (1 - A) × (1 - A) × A + (1 - A) × (1 - A) × (1 - A) × (1 - A) × A + (1 - A) × (1 - A) × (1 - A) × (1 - A) × (1 - A) × A + (1 - A) × (1 - A) ×  (1 - A) × (1 - A) × (1 - A) × (1 - A) × A.

Answer:

- 1/6

Step-by-step explanation:

Answer:

y=-1/2x+b

Step-by-step explanation:

we can see that the line is going through (0,9) and the closest point is goes through next is (1,7).

so knowing that y=mx+b, we can plug in numbers to this equation.

take on of the points, and find the slope. the slope is -1/2.

so we would plug in one of our points plus the slope into our equation:

7=-1/2(1) +b

now we do the algebra and find that 7 1/2 =b.

so now the equation is y=-1/2x+b.

Answer:

t= -1

Step-by-step explanation:

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

[tex] \frac{1}{7} = \frac{ - 7 - ( - 6)}{t - 6} [/tex]

[tex] \frac{1}{7} = \frac{ - 7 + 6}{t - 6} [/tex]

[tex] \frac{1}{7} = \frac{ - 1}{t - 6} [/tex]

cross multiply:

1(t -6)= 7(-1)

t -6= -7

+6 on both sides:

t= -7 +6

t= -1

k=4 C) is the correct answer.

Option B is correct

Answer:

A large box costs $19.

A small box costs $16

Step-by-step explanation:

s = cost of a small box

l = cost of a large box

From the problem, we can make these two formulas.

# of small boxes + # of large boxes = total cost

10s + 3l = 217

3s + 12l = 276

Rewrite one equation for either s or l:

3s = 276 - 12l

s = 92 - 4l

Now use substitution to solve. Plug the s equation from above into

10s + 3l = 217

10 (92 - 4l) + 3l = 217

920 - 40l + 3l = 217

-37l = -703

l = 19

This is the cost of a large box.

Plug l into:

s = 92 - 4l

s = 92 - 4(19)

s = 16

This is the cost of a small box.

Since you need conversion from meters to centimetres, thus, you need some data about how does a meter relates to centimetre.

Thus, Option D: 100cm = 1m is the equality which will be useful for given calculation.

If a quantity is expressed in one unit and has to be converted to other unit, then you need to have some data by which you can relate those two units together so as to know how much of first scale is equal to that of a unit of second scale or vice versa.

Since the given quantity asks to know how many centimetres are there in a meter, thus from given option, the fourth option is most appropriate and useful.

Thus,

Option D:  100cm = 1m is the equality which will be useful for given calculation.

Answer:

x < 5, so the increase must be less than 5°F or there will be school

Step-by-step explanation:

By direct division, we will find that the length of each piece of rope is 10.5m

So e start with a 42 meter long rope and we cut it into 4 equal parts, then we know that each one of these pieces will have a length equal to:

L = (42m/4)

To perform that division, you can see that 42 is not a multiple of 4, so we can write:

L = (40m + 2m)/4 = (40m/4) + (2m/4)

The first quotient is just equal to 10m, while the second one is:

(2m/4) = (1m/2) = 0.5m

Then we have:

L =  (40m/4) + (2m/4) = 10m + 0.5m = 10.5m

Each piece of rope has a length of 10.5m

Answer:  [tex]p = -10+\sqrt{3}[/tex]

When writing this on a keyboard, we could say p = -10+sqrt(3)

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

Explanation:

We're told the angle between the line and x axis is [tex]\tan^{-1}\left(\frac{-1}{\sqrt{3}}\right)[/tex]

This is one of the infinitely many exact solutions to the equation [tex]\tan(\theta) = \frac{-1}{\sqrt{3}}[/tex] where [tex]\theta[/tex] (Greek letter theta) is the angle in question.

It turns out that the tangent ratio is exactly the slope of a line.

Both describe a ratio of how far something moves up or down, over how far it moves to the right.

So saying [tex]\tan(\theta) = \frac{-1}{\sqrt{3}}[/tex] means that the slope of our mystery line is exactly [tex]\frac{-1}{\sqrt{3}}[/tex]

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

What we'll do is compute the slope on the points [tex](\ -p, -2\sqrt{3} \ ) \text{ and } (4, -1)[/tex]

That produces some algebraic expression in terms of p. That expression is set equal to the previously mentioned slope of [tex]\frac{-1}{\sqrt{3}}[/tex] which will allow us to solve for p.

Part 1

[tex]m = \text{slope}\\\\m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-1-(-2\sqrt{3})}{4-(-p)}\\\\m = \frac{-1+2\sqrt{3}}{4+p}\\\\-\frac{1}{\sqrt{3}} = \frac{-1+2\sqrt{3}}{4+p} \ \ \text{ ... plug in the previously mentioned slope}\\\\-(4+p) = (\sqrt{3})(-1+2\sqrt{3}) \ \ \text{ ... cross multiply}\\\\[/tex]

To solve the problem we must know about the equation of a circle and complex numbers.

Radius² = (Distance between the center and any point on the circle)²

Radius = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Complex Number, z = (x +iy)

Another point that will lay on the same circle is (12 + 10i).

Given to us

Solution

We know that equation for a circle can be written as,

Radius of the Circle

= √(Distance between the center and any point on the circle)²

Radius of the Circle = √[4-19]²+[-5 -(-13)]²

                                 = √[-15]²+[8]²

                                 = √225 + 64

                                 = √225 + 64

                                 = √289

                                 = 17

Now compare the distance between the center of the circle and the points.

A.)  –11 –3i

Distance between the center and point on the circle

= √[4-(-11)]² + [-5 - (-3)]²

= √[15]² + [-2]²

= √225 + 4

= √229

B.)  –4. 5+3. 5i

Distance between the center and point on the circle

= √[4-(-4.5)]² + [-5 - (3.5)]²

= √[9.5]² + [-8.5]²

= √90.25+ 72.25

= √162.5

C.)  12 + 10i

Distance between the center and point on the circle

= √[4-(12)]² + [-5 - (10)]²

= √[-8]² + [-15]²

= √64+ 225

= √289

= 17

D.)  21 + 12i.

Distance between the center and point on the circle

= √[4-(21)]² + [-5 - (12)]²

= √[17]² + [-17i]²

= √289+ 289

= √578

Hence, another point that will lay on the same circle is (12 + 10i).
