LeAnn is playing a math game. She chooses three cards. The value of each of her cards is shown.


First card: -12

Second card: 3

Third card: -5


What is the sum of the values of LeAnn’s three cards?

Answer:

The answer is D.

Step-by-step explanation:

a) Plugging x = 18 gets numerator 0^2/18 = 0 that not continuous.

b) Plugging x = 18 the denomiator becomes a value/0 making it undefined.

c) Plugging x = 18 gets tan(2pi) = 0/1 which is 0

d) f(x) = 36 is should be a straight lines at y =36. I think. Best option is D.

The vertices of the polygon form a trapezoid, and the area of the polygon is 28 unit squares

The vertices are given as:

C = (3,3)

A = (8,-2)

S = (3,-4)

H = (0, -2)

The area of the polygon is calculated using:

[tex]A = \frac 12 \sum\limits^{n-1}_{k = 0}(x_ky_{k+1} - y_kx_{k+1})[/tex]

So, we have:

A = 1/2 * |(3 * -2 - 8 * 3 + 8 * -4 - 3 * -2 + 3 * -2  - 0 * -4 + 0 * 3 -3 * -2)|

Evaluate

A = 1/2 * |-56|

Remove the absolute bracket

A = 1/2 * 56

Evaluate the product

A= 28

Hence, the area of the polygon is 28 unit square

Answer:

A. 5.4

Step-by-step explanation:

I think... I haven't done this sort of question in a while

A Circle is a closed plane geometric shape figure. The diameter of a circle is the longest chord of a circle. The radius drawn perpendicular to the chord bisects the chord. A Circle is always lie at an equal distance from a center point. Circles having different radius are similar.

The area of a circle is pi times the radius squared. The unit of area of circle is square units.

[tex]\longrightarrow Area_{(circle)} = \pi r^2[/tex]

Here, r is the radius of the circle.

We are asked to find the area of the circle in terms of pi if the diameter is 7 inches.

We know that, the diameter is twice the length of the radius of a circle. Therefore;

Now the area of circle will be:

[tex]\implies Area_{(circle)} = \pi r^2[/tex]

[tex]\implies Area_{(circle)} = \pi (3.5)^2[/tex]

[tex]\implies Area_{(circle)} = 12.25 \pi[/tex]

Hence, the area of the given circle is 12.25π square inches.

Answer:

Step-by-step explanation:

In the question we are given that diameter of circle is of 7 inches . And we have asked to find the area of the circle in term of pi ( π ) .

For finding area of circle we must have to know that what is the formula for finding area of circle. So :

[tex] \qquad \qquad \: \red{\underline{\red{ \boxed{ \frak{Area \: of \: Circle = \pi r {}^{2} }}}}}[/tex]

Where ,

Solution : -

As in the question we are given length of diameter . So for finding area we need to find the radius of circle .

We know that diameter of circle is two times its radius or ,

[tex] \qquad \: \rm {Diameter = 2 × Radius }[/tex]

So for radius we are dividing both side with 2 :

[tex]\qquad \: \rm { \dfrac{Diameter}{2} = \dfrac{ \cancel{2} × Radius}{ \cancel{2}} }[/tex]

We get that ,

[tex] \qquad \: \rm {Radius = \dfrac{Diameter}{2} }[/tex]

Therefore , we can say that radius of circle is half of its diameter .

Now using this firstly we are finding radius of circle . So :

[tex] \longmapsto \quad \: \boxed{\rm{ Radius = \frac{7}{2} \: \: inches}}[/tex]

Now , we are moving towards our final solution .

So ,

[tex] \longrightarrow \quad \: Area_ { (Circle)} = \pi( \dfrac{7}{2} ) {}^{2} [/tex]

Calculating further :

[tex]\longrightarrow \quad \: Area_ { (Circle)} = \pi \times \dfrac{7}{2} \times \dfrac{7}{2} [/tex]

After multiplication of 7/2 with 7/2 we get :

[tex]\longrightarrow \quad \: Area_ { (Circle)} = \pi \times \dfrac{49}{4} [/tex]

On dividing 49 by 4 we get :

[tex]\longrightarrow \quad \: \blue{{\boxed{\frak{Area_ { (Circle)} = 12.25\pi \: inches {}^{2} }}}}[/tex]

Remember one thing , we haven't put value of π as 22/7 or 3.14 because in the question it is given that we have to find the area of circle in terms of pi .

Answer:

37 decreased by 20% is 29.6.

Step-by-step explanation:

To do this, what we do is simply take 20% of 37 and subtract it from 37.

20% of 37. A trick to easily figure this out is multipling 37 by 20 and dividing by 100.

37*20 = 740

740 / 100 = 7.40

37 - 7.40 = 29.6

37 decreased by 20% is 29.6.

13 dollars a pizza because if you put 4x13 that is 52 then add the wings 8$ that is your answer 60....

Step-by-step explanation:

Hopefully It helped ya... (:

Answer:

p = 12

Step-by-step explanation:

Given:

Jalen bought 4 pizzas. He also spent $8 on wings. He paid a total of $60. He can use the equation 4p + 8 = 56 to determine the price of each pizza.

To Find:

How much was each pizza?

Solution:
Since it already given a equation thus we can just solve using the equation given:

4p + 8 = 56

Subtract 8 from both sides

4p + 8 = 56

      - 8     -8

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

4p = 48

Divide both sides by 4

4p/4 = 48/4

p = 12

Hence, each pizza cost $12.

Kavinsky

Answer: The answer is five

Step-by-step explanation:

Set y = z

50x + 75 = 65x

Subtract 50x from both sides

50x (-50x) + 75 = 65x (-50x)

75 = 15x

Divide both sides by 15

75 (/15) = 15x (/15)

5 = x

And there we have it, x = 5! So it takes 5 hours of work for each to cost the same.

x^3(-x+3)(x+3)

Step-by-step explanation:

-x^5 + 9x^3

factor out x^3

x^3(-x^2+9)

9 and -x^2 are perfect squares so we can factor out a 3 and an x to get (-x+3)(x+3)

the fully factored form would be x^3(-x+3)(x+3)

Answer:

-x^3(x - 3)(x + 3).

Step-by-step explanation:

-x^5+9x^3

the greatest common factor = x^3 so we can write it as

x^3(-x^2 + 9)

= -x^3(x^2 - 9)

The expression in the parentheses is the difference of 2 squares so we have:

-x^3(x - 3)(x + 3)   Answer.

Answer:

Step-by-step explanation:

-x + 2y = 16

y = mx + 8

Start with the top equation. Add x to both sides.

-x + 2y + x = x + 16                     Combine the left

2y = x + 16                                  Divide by 2

2y/2 = (1/2)x + 1/2(16)

y = 1/2 x + 8

If m = 1/2, both equations together will give an infinite number of solutions.

Answer:

1/6.

Step-by-step explanation:

Prob(Tail) = 1/2

Prob(gets number > 4 ,  that is a 5 or a 6) = 2/6 = 1/3.

So required probability = 1/2 * 1/3

= 1/6.

The individual probabilities are multiplied as the 2 events are independent.

The probability that Mario gets tails and rolls a number greater than 4 is,

⇒ 1 / 6

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

Mario flips a coin, then rolls a standard six-sided number cube.

Now, We get;

The probability to get tails is,

⇒ 1 / 2

And, The probability to get a number greater than 4 (5 and 6) is,

⇒ 2 / 6

⇒ 1 / 3

Thus, The probability that Mario gets tails and rolls a number greater than 4 is,

⇒ 1/2 × 1/3

⇒ 1 / 6

Answer:

number of action figures = 3 + 6(n-1)

at n = 9: number of action figures = 51

Step-by-step explanation:

first row: 3

second row: 6 more than the row before it (3) = 6 + 3 = 9

third row: 6 + 9 = 15

arithmetic series: [tex]a_n = a_1 + (n-1)d[/tex], where

[tex]a_n[/tex] is the nth term in the output

[tex]a_1[/tex] is the first output

n is the input

d is the difference between terms

here, we are given the row, and we want to figure out the number of action figures. thus, row = input and number of action figures = output.

the first output, in the first row, is 3

the difference between the number of action figures in each row is 6

thus, our formula is

[tex]a_n = 3 + (n-1)6 = 3 + 6(n-1)[/tex]

when the row is 9, the number of action figures is equal to

The question is an illustration of sample and population, and the estimate of the population of squirrel in the park is 55

The given parameters are:

Marked squirrels = 43

Captured squirrels = 50

Of the 50 captured squirrels, 38 are from the marked squirrels.

This means that the number of unmarked squirrels is:

Unmarked = 50 - 38

Evaluate

Unmarked = 12

The population of the squirrel is then calculated using:

Population = Marked + Unmarked

So, we have:

Population = 43 + 12

Evaluate the sum

Population = 55

Hence, the estimate of the population of squirrel in the park is 55
