Find the missing angle of a triangle if the first two values are 91* and 87 degrees

the set of 6 consecutive integers starting with -3:

{ -3,-2,-1,0,1,2 }

Answer:

Step-by-step explanation:

let :

x , x+1 , x +2 , x + 3 , x+4 , x+5 ....... ( 6  consecutive integers )

x +( x+1 ) + (x +2) + (x + 3)+ (x+4) + ( x+5) = - 3

6x+16 = - 3

6x = - 3 - 16

6x = - 18

x v= -18/6

x = - 3

6  consecutive integers  are : -3  ; - 2 ; - 1 ; 0 ; 1 ; 2

Answer: 51 feet

Since we know George's height, the length of George's shadow, and the length of the flagpole's shadow we have all the information we need

Now we can set up a relationship between George and the flagpole:

[tex] \frac{6}{10} = \frac{x}{85} [/tex]

6 represents George's height

10 represents the length of George's shadow

x is the unknown height of the flagpole

85 is the length of the flagpole's shadow

Now you solve for x:

[tex]x = \frac{85 \times 6}{10} \\ x = \frac{510}{10} \\ x = 51[/tex]

So, the height of the flagpole is 51 feet

Answer:

55mph

Step-by-step explanation:

car A distance, d1= 220

car b distance, d2= 260

speed of car A, s1= speed of car B- 10

let speed of car B be s2

s1= s2-10

speed = distance/time

time= distance/speed

As time of car A= time of car B

     distance of Car A/speed of Car A=distance of Car B/speed of Car B

220/s2-10= 260/s2

s2=(s2-10)260/220

s2=65

s1= s2- 10

  = 65-10

   =55

hence speed of first car is 55mph !

Answer: 55 mph

Answer:

x=-2

Step-by-step explanation:

Answer:

x = - 2

y = 7

Step-by-step explanation:

4x - 2y = - 20

Now substitute - 3x for y.

4x - 2(-3x) = -20           combine the xs in the brackets

4x + 6x = - 20               Make the addition      

10x = - 20                      Divide by 10

x = - 20/10                     Do the division

x = - 2                            

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

3x - 2y = - 20                 Put - 2 in for x  

3(-2) - 2y = - 20              remove the brackets              

- 6 - 2y = - 20                 Add 6 to both sides

-2y = - 20 + 6                 Combine

-2y = - 14                         Divide by - 2

y = - 14/-2                        

y = 7

7x + 12 = 3(5x - 12)

Step 1: Distribute the 3 to the numbers in the parentheses (5x and -12)

7x + 12 = (3 × 5x) + (3 × (-12))

7x + 12 = 15x + (-36)

Step 2: Combine like terms

x's go with x's (7x and 15x)

Subtract 7x to both sides

(7x - 7x) + 12 = (15x - 7x) + (-36)

(0) + 12 = 8x - 36

12 = 8x - 36

Normal numbers go with normal numbers

Add 36 to both sides

12 + 36 = 8x + (-36 + 36)

48 = 8x

Step 3: Isolate x by dividing 8 to both sides

48/8 = 8x/8

6 = x

Hope this helped!

Answer:

x = 6

Step-by-step explanation:

Eliminate parentheses using the distributive property.

7x +12 = 15x -36

You have x-terms and constants on both sides of the equal sign. One way to approach this is to find the x-term with the least coefficient (it is 7x) and subtract everything on that side of the equation.

(7x +12) -(7x +12) = (15x -36) -(7x +12)

Simplify, also known as "collect terms."

0 = 8x -48

Now, divide by the coefficient of x: 8.

0 = x -6

Add the opposite of the constant: 6.

6 = x

__

Alternate solution

By looking for the x-term with the smallest coefficient, we get a positive result when we subtract that term. If we were to subtract 15x from both sides of the equation, it would be ...

-8x +12 = -36 . . . . . . . with a negative x-coefficient

You can still work the problem this way, but it can introduce errors if you're not careful with signs. To finish this, we would subtract 12 to get the x-term by itself:

-8x = -48

Then we would divide by the x-coefficient, -8.

x = -48/-8 = 6 . . . . . same solution; same number of steps

Whenever you add, subtract, multiply, divide, you do the same thing to both sides of the equation.

Answer:

parenthesis

Step-by-step explanation:

A common technique that is being used in solving with several arithmetic operations is the PEMDAS. It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". It is the order to be followed when calculating involving more than one arithmetic operation.

The correct first operation to perform in a calculation involving multiple arithmetic operations is parentheses, as per the order of operations, known as PEMDAS or BEDMAS.

The correct operation that should be performed first for calculations involving more than one arithmetic operation is parentheses. According to order of operations, the sequence you would follow is: Parentheses (or grouping symbols), Exponents, Multiplication and Division (from left to right), and finally Addition and Subtraction (from left to right). This is also commonly remembered by the acronym PEMDAS in the American system or BEDMAS in the Canadian system, indicating the sequence: Parentheses/Brackets, Exponents, Multiplication/Division, and Addition/Subtraction.

For this case we have the following function:

[tex]c (f) = \frac {5} {9} (f-32)[/tex]

We must find the inverse function. For this we follow the steps below:

Replace c (f) with y:

[tex]y = \frac {5} {9} (f-32)[/tex]

We exchange variables:

[tex]\frac {5} {9} (y-32) = f[/tex]f = \frac {5} {9} (y-32)

We solve for "y":

[tex]\frac {5} {9} (y-32) = f[/tex]

We multiply by[tex]\frac {9} {5}[/tex]on both sides of the equation:

[tex]y-32 = \frac {9} {5} f[/tex]

We add 32 to both sides of the equation:

[tex]y = \frac {9} {5} f + 32[/tex]

We change y by[tex]c^{ -1} (f):[/tex]

[tex]c^{-1} (f) = \frac {9} {5} f + 32[/tex]

Answer:

[tex]c^{-1} (f) = \frac {9} {5} f + 32[/tex]

Answer:

[tex]f(c)=\frac{9}{5}c+32[/tex]

Step-by-step explanation:

Given function that is used to convert degrees to Fahrenheit to degrees Celsius,

[tex]c(f)=\frac{5}{9}(f-32)[/tex]

Let y represents the output value of the function and x represents the input value,

[tex]y=\frac{5}{9}(x-32)[/tex]

Switch x and y,

[tex]x=\frac{5}{9}(y-32)[/tex]

Isolate y,

[tex]9x=5(y-32)[/tex]

[tex]\frac{9}{5}x=y-32[/tex]

[tex]\implies y = \frac{9}{5}x+32[/tex]

[tex]\implies f(c)=\frac{9}{5}c+32[/tex]

Which is the required function.

Final answer:

The question appears to involve solving a quadratic equation using the quadratic formula, but there seems to be a typo in the provided figures. Nevertheless, the solution process entails substituting the given values into the quadratic formula and solving for x, which may result in two possible solutions depending on the discriminant.

Explanation:

The question involves solving a quadratic equation of the form ax² + bx + c = 0 using the quadratic formula, which is x = (-b ± √(b² - 4ac)) / (2a). Based on the provided values of a, b, and c, we would substitute these into the quadratic formula to find the solutions to the equation. It seems there may be a typo in the original question, as the given values do not match any standard form of a quadratic equation nor the matrix form of a linear system. However, I will provide a general step-by-step solution for the quadratic equation based on the format provided in the reference information.

First, calculate the discriminant using the formula √(b² - 4ac). Then, use the values of a, b, and c to evaluate the positive and negative solutions of x using the quadratic formula. For example, if a = 1, b = 0.0211, and c = -0.0211, the solutions would be found as follows:

-0.0211 ± √(0.0211)² - 4(1)(–0.0211)

2(1)

It is important to note that this structure is indicative of the process and the actual computations will differ with the correct values provided for a, b, and c.

Answer:

518.4 in³

Step-by-step explanation:

The ratio of the sides of the prisms = 5 : 6, hence

the ratio of their volumes = 5³ : 6³ = 125 : 216

let x be the volume of the larger prism then by proportion

[tex]\frac{125}{300}[/tex] = [tex]\frac{216}{x}[/tex] ( cross- multiply )

125x = 216 × 300 ( divide both sides by 125 )

x = [tex]\frac{216(300)}{125}[/tex] = 518.4

The volume of the larger prism is 518.4 in³

Answer:

9 bottles of soda can be bought.

Step-by-step explanation:

Let chips represented by x

and soda represented by y

then

x + y = 14     eq(1)

and

5x + 3y = 52    eq(2)

Solving the equations simultaneously we can find the value of x and y

Multiplying eq(1) with 5 and subtracting from eq(2)

5x + 3y = 52

5x + 5y = 70

-     -        -

___________

-2y = -18

y = -18/-2

y = 9

Putting value of y in eq(1)

x + y =14

x + 9 = 14

x = 14 - 9

x = 5

As y represents the soda, so 9 bottles of soda can be bought.

rolling a 5= 11/100

getting tails=71/29

i’m pretty sure you times the fractions together to get an overall probability

The probability of rolling a 5 on number cube and tail on coin is:

            [tex]P(A\bigcap B)=\dfrac{781}{10000}[/tex]

                                      or

          [tex]P(A\bigcap B)=0.0781[/tex]      

Let A denote the event of rolling a 5 on the number cube.

and B denote the event of coin landing on tails.

Let P denote the probability of an event.

Also, event A is independent of event B.

( Since, both the events are not affected by happening of each other )

We are asked to find the probability:  P(A∩B)

We know that:

[tex]P(A\bigcap B)=P(A)\cdot P(B)[/tex]

( Since, both the events are independent )

Also,

[tex]P(A)=\dfrac{11}{100}[/tex]

( Since, 5 occurs 11 times out of a total of 100 times on the number cube )

and

[tex]P(B)=\dfrac{71}{100}[/tex]

Hence, we have:

[tex]P(A\bigcap B)=\dfrac{11}{100}\times \dfrac{71}{100}[/tex]

i.e.

[tex]P(A\bigcap B)=\dfrac{781}{10000}[/tex]

i.e.

[tex]P(A\bigcap B)=0.0781[/tex]

in short, we simply graph her countertpart of y = 7, and then we test a point for "true" or "false" for that region.

say for example the point ( 3, 5 ), meaning x = 3, y = 5

y < 7

5 < 7  

is that really true?  5 smaller than 7?  yeap, so that region is the "true" region, and is the region we shade.

the line in the graph is a dashed one, because it does NOT include the points at the border, y < 7, "y" is less, not equals to, but less than 7.

It’s important to keep PEMDAS in mind (order of operations) when solving this.

PEMDAS stands for: Parentheses, exponents, multiplication, division, addition, subtraction.

So when doing this problem we can see that there are two multiplication problems (8 • 9) and (2 • 5) so let’s put those to the side and solve those.

8 • 9 = 72

2 • 5 = 10

Now we can put the problem back together as 72-10

So ... 72-10=62

Answer:

The answer is 6 schools.

In a box and whisker plot, every piece of whisker or box represents 25% of the whole number of schools.

The schools participated 1 year or less are represented by the left part of the whisker. Which stands for 25%.

BOOM

Step-by-step explanation:

On analyzing the boxplot, we find that 6 schools have participated for 1 year or less.

A boxplot is a standardized way of displaying the distribution of data based on a five number summary (minimum, first quartile (Q1), median, third quartile (Q3), and maximum).

The box extends from 1 to 6 on the number line. This implies first quartile (Q1) = 1 and third quartile (Q3) = 6.

There is a vertical line at 3.5, median = 3.5.

The whiskers end at 0 and 8, i.e., minimum = 0 and maximum = 8.

Since, Q1 = 1, this implies 25% of the schools participated for 1 year or less.

(First quartile (Q1) is the value under which 25% of data points are found when they are arranged in increasing order.)

Number of schools that have participated for 1 year or less = 25% of 24 = [tex]\frac{25}{100} * 24 = 6[/tex]
