Subtracting -9 from any number is the same as

Answer:

c, b, a

Step-by-step explanation:

Because angles in a triangle add up to 180 degrees, we know that the unknown angle is 180-(55+68), or 57 degrees. Because of the side-angle inequality theorem, we know that B is equal to 57 degrees, C is equal to 68 degrees, and A is equal to 55 degrees.

68>57>55

Step-by-step explanation:

i hope i have been useful buddy.

good luck ♥️♥️♥️♥️♥️.

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.

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.

Therefore the closest estimate to the final answer would be 5289.25 cm squared

[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]

10 1/9

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

10 3/27, to simplify

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.

Answer:

D

Step-by-step explanation:

The option fourth represents the difference quotient of the function f(x) option fourth is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

[tex]\rm f(x) = - \sqrt{8x-35}[/tex]

[tex]\rm f(x+h) = - \sqrt{8(x+h)-35}\\\\\rm f(x+h) = - \sqrt{8x+8h-35}\\\\[/tex]

Difference quotient:

[tex]\rm = \dfrac{f(x+h)-f(x)}{h}[/tex]

[tex]\rm = \dfrac{- \sqrt{8x+8h-35}+ \sqrt{8x-35}}{h}[/tex]

After rationalization;

[tex]\rm = \dfrac{- \sqrt{8x+8h-35}+ \sqrt{8x-35}}{h} \times \dfrac{ \sqrt{8x+8h-35}+ \sqrt{8x-35}}{\sqrt{8x+8h-35}+ \sqrt{8x-35}}[/tex]

[tex]\rm = \dfrac{8}{-\sqrt{8x+8h-35}- \sqrt{8x-35} }[/tex]     , h ≠ 0

Thus, the option fourth represents the difference quotient of the function f(x) option fourth is correct.

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 answer is “B” (Reflects over the x-axis)

Step-by-step explanation:

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) ].

Answer:

[tex]\frac{5}{11}[/tex]

Step-by-step explanation:

The line over 45 indicates 45 is being repeated, that is

0.4545....

Create 2 equations with the repeating values after the decimal point

let x = 0.4545..... → (1) ( multiply both sides by 100 )

100x = 45.4545..... → (2)

Subtract (1) from (2) eliminating the repeating decimal

99x = 45 ( divide both sides by 99 )

x = [tex]\frac{45}{99}[/tex] = [tex]\frac{5}{11}[/tex]

Thus 0.4545... = [tex]\frac{5}{11}[/tex]

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]
