Step-by-step explanation:

((-3+2)/2),((-5+5)/2)

(-0.5),(0)

Answer:

(-0.5,0)

Step-by-step explanation:

Mid point is the point at the middle of the line, therefore takings the average Y value and the average X value, will obtain the middle point.

Y point: (-3+2)/2 = -0.5

X point: (-5+5)/2 = 0.0

Midpoint: (-0.5,0)

Answer:

[tex]x<-6\text{ or } x>2[/tex]

Step-by-step explanation:

We have the inequality:

[tex]\frac{2}{5}|5x+10|-14>-6[/tex]

First, we can factor out a 5 from our absolute value. This yields:

[tex]\frac{2}{5}(5|x+2|)-14>-6[/tex]

Simplify:

[tex]2|x+2|-14>-6[/tex]

Add 14 to both sides:

[tex]2|x+2|>8[/tex]

Divide both sides by 2:

[tex]|x+2|>4[/tex]

Definition of Absolute Value:

[tex]x+2>4\text{ or } -(x+2)>4[/tex]

Solve each case individually:

Case 1:

[tex]x+2>4[/tex]

Subtract 2 from both sides:

[tex]x>2[/tex]

Case 2:

[tex]-(x+2)>4[/tex]

Divide both sides by -1. Flip the sign:

[tex]x+2<-4[/tex]

Subtract 2 from both sides:

[tex]x<-6[/tex]

So, our answers are:

[tex]x<-6, x>2[/tex]

Since our inequality is a greater than, we will have an "or" inequality.

So, our answer is all values left to the first solution and all values to the right of the second solution:

[tex]x<-6\text{ or } x>2[/tex]

And we're done!

Answer:

Step-by-step explanation:

The meaning of the solution x < - 10 or x ≥ 25 is the solution is in the interval (- ∞,- 10) ∪ [25, ∞).

An interval is a collection of real numbers that lie between two given values known as the interval's endpoints.

We are aware that two sets' components were combined to create the set. The set of elements in A, B, or both is the result of adding sets A and B together. It's indicated by '∪'.

For x < - 10 , the solution is in the interval (- ∞,- 10).

For x ≥ 25, the solution is in the interval [25, ∞).

For x < - 10 or x ≥ 25, we can say that the solution is in the interval

(- ∞,- 10) ∪ [25, ∞).

Therefore the meaning of the solution x < - 10 or x ≥ 25 is the solution is in the interval (- ∞,- 10) ∪ [25, ∞).

Answer:

Probability at least one car will get punctured: 0.39347

Step-by-step explanation:

B(10,000 , 0.00005)

P(X ≥ 1) = 1 - P(X = 0)

            = 1 - (1 - 0.00005)^10,000

            = 1 - (0.99995)^10,000

            = 1 - 0.60652...

            = 0.39347 (probability that at least one car will get punctured)

As you can tell P(X ≥ 1) as we have to solve for the probability that at least one car will get punctured. That is of course 1 - [ P(X = 0) ].

Problem 1

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

Work Shown:

1 liter = 1000 mL

0.56 liters = 560 mL (multiply both sides by 0.56)

x = number of tablespoons needed to fill water bottle

1 tablespoon = 15 mL

x tablespoons = 15x mL (multiply both sides by x)

Set 15x and 560 equal to each other. Solve for x

15x = 560

x = 560/15

x = 37.333

x = 37.33

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

Problem 2

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

Work Shown:

From the previous problem, a 0.56 L water bottle has 560 mL of water.

Subtract off 15 mL to get

560 - 15 = 545

A filled water bottle has 545 more mL of water compared to a tablespoon of water.

The year in which the total personal income will reach 22 trillion dollars is 2033 years.

The year in which the total personal income will reach 22 trillion dollars is calculated by applying a method known as extrapolation for the data in the table.

At year 1996, total personal income = 8429.2

At year 2001, total personal income = 10,239.5

At year ?, total personal income = 22,000

(? - 2001) / (2001 - 1996) = (22,000 - 10,239.5) / (10,239.5 - 8429.2)

(? - 2001 ) / 5 = 6.496

? - 2001 = 5 x 6.496

? - 2001 = 32.48

? = 2001 + 32.48

? = 2033.48

? ≈ 2033 years

Thus, the year in which the total personal income will reach 22 trillion dollars is 2033 years.

Answer:

x=20

Step-by-step explanation:

x/24 = 30/36 simplify

x/24 = 5/6 divide 24 by 6 and multiply it to 5

x = 20

The solution to the equation x/24 = 30/36 is x = 20.

Option A is the correct answer.

We have,

To solve the equation x/24 = 30/36, we can cross-multiply and solve for x.

Cross-multiplying gives us:

36x = 24 * 30

Simplifying further:

36x = 720

Now, we can divide both sides of the equation by 36 to isolate x:

x = 720/36

Simplifying the right side:

x = 20

Therefore,

The solution to the equation x/24 = 30/36 is x = 20.

The solution that is the closest estimate of the amount of glass Maria will need to construct her pyramid would be =5289.25 cm squared. That is option C.

To calculate the area of a square based pyramid, the formula that should be used would be given below as follows:

[tex]area = {a}^{2} + 2a \sqrt{ \frac{a2}{4} } + {h}^{2} [/tex]

Where:

a= 44cm

height= 44²-22²= 38.1cm

Area= 44²+ 2(44) × √44²/4 + 38.1²

= 1936+88 × √ 484+1452

= 2024× √1936

= 5807.61 cm².

Step-by-step explanation:

To make it easier to answer, make both of them into an improper fraction

4 1/5 = 21/3

1 4/9 = 13/9

Now we can multiply them easier

21/3 x 13/9 = 273/27

27 goes into 273 10 times and the left over is 3 so the mixed fraction would be

Two angles are complementary when their sum is equal to 90°.

So, ( 2x + 39 ) + ( 7x - 21 ) = 90°

9x + 18° = 90°

x = 8°

Putting value of x in the angles given :

( 2x + 39 )° = 2(8°) + 39° = 55°.

( 7x - 21 )° = 7(8°) - 21° = 35°.

Therefore, the angles are 55° and 35°.

Hence, this is the required solution.

[tex]\boxed{\pink{\sf The \ inverse\ of \ the \ function \ is \ f^{-1}(x)= \dfrac{2}{x}-\dfrac{1}{2} }}[/tex]

Step-by-step explanation:

A function is given to us and we need to find its inverse . So the given function is ,

[tex]\implies f(x) = \dfrac{4}{2x+1} [/tex]

1) So ,let us take f(x) = y . Equation becomes ,

[tex]\implies y = \dfrac{4}{2x+1} [/tex]

2) Firstly replace x with y and y with x. We get ,

[tex]\implies x = \dfrac{4}{2y+1} [/tex]

3) Now , solve for y.

[tex]\implies x = \dfrac{4}{2y+1} \\\\\implies x(2y + 1) = 4 \\\\\implies 2y+1 =\dfrac{4}{x}\\\\\implies 2y = \dfrac{4}{x}-1 \\\\\implies 2y = \dfrac{4-x}{x} \\\\\implies y = \dfrac{4-x}{2x} [/tex]

4) Now replace y with [tex]f^{-1}(x) [/tex]

[tex]\implies f^{-1}(x) = \dfrac{4-x}{2x} \\\\\ \implies f^{-1}(x)= \dfrac{4}{2x} - \dfrac{x}{2x} \\\\\underline{\boxed{\orange{\tt \implies f^{-1}(x) = \dfrac{2}{x}-\dfrac{1}{2} }}}[/tex]

Answer:

A) Each of the smaller donations is $20.

B) The larger donation is greater than the smaller donations by $15.

Step-by-step explanation:

4+4+7 is equal to 15, and divide 75 by 15 to get $5 per part. Multiply 4 by 5 to get $20 for a smaller donation, and 7 by 5 to get $35 for the larger donation. Hope this helped :)

Answer:

Smaller donations each cost $20

The bigger donation is $15 more than the smaller ones.

Step-by-step explanation:

Let 4x be defined as the amount of the smaller donation, and let 7x be defined as the larger amount of the donation. We can then set up an equation:

4x+4x+7x = 75

15x = 75

x = 5

We can now plugin 5 for x to solve for the smaller donation and the larger donation:

Smaller donation = 4*5 = 20

Bigger donation = 7*5 = 35

Now, to find how much greater the bigger donation is, we just subtract 35 from 20, which is 15.

Answer: Samuel no necesita comprar mas cajas.

Step-by-step explanation:

Cada mosaico es un cuadrado de 20cm por lado.

Entonces el área de cada mosaico es:

A = 20cm*20cm = 400cm^2.

En una caja hay 14 mosaicos, entonces cada caja puede cubrir:

14*400cm^2 = 5,600cm^2.

Ahora, el problema dice que la pared mide 3cm por 2 cm.

En ese caso, con un solo mosaico cubrirías la pared, entonces supongo que esta mal escrito.

Las dimensiones de la pared serian 3 metros por 2 metros.

1 m = 100cm

Entonces la pared es 300cm por 200cm.

El área total de la pared seria:

300cm*200cm = 60,000cm^2.

Ahora, cada caja de mosaicos cubre 5,600 cm^2.

Entonces el numero de cajas necesarias para cubrir toda la pared es:

(60,000cm^2)/(5,600cm^2) = 10.7

Entonces se necesitan 10.7 cajas para cubrir esa pared, y Samuel tiene 11, entonces el no necesita comprar mas cajas.

Samuel necesita 150 mosaicos, y en sus cajas tiene 154, por lo que no necesita comprar más cajas.

Dado que Samuel tiene 11 cajas con mosaicos cuadrados de 20 cm por lado, y quiere cubrir una pared que mide 3 metros de largo y 2 metros de alto, si en caja hay 14 mosaicos, para determinar si será necesario que compre mas cajas se debe realizar el siguiente cálculo:

Por ende, se necesitan 150 mosaicos para cubrir toda la pared.

A su vez, en total Samuel tiene 154 mosaicos.

Por lo tanto, Samuel no necesita comprar más cajas.
