Complementary angle add up to 90 degrees.

Angle A = x + 6

Angle B = x

They both add up to 90.

x + 6 + x = 90

2x + 6 = 90

2x = 90 - 6

2x = 84

x = 84/2

x = 42

Angle A = x + 6

Angle A = 42 + 6

Angle A = 48 degrees

Factorizing:

(n-9)(n-5) = 0

Therefore, the solution set of n2 - 14n = -45 is {5, 9}

Answer:

C x= 0   greater than

E x= 10 greater than

Step-by-step explanation:

4(2 – x) > –2x – 3(4x + 1)

Distribute

8 –4x > –2x – 12x -3

Combine like terms

8 –4x > – 14x -3

Add 14x to each side

8 –4x+14x > – 14x+14x -3

8 +10x >  -3

Subtract 8 from each side

8-8+10x>-3-8

10x > -11

Divide each side by 10

10x/10 >-11/10

x >-1.1

Any number greater than -1.1 is a solution

A x= -1.1   not greater than

B x= -2.2   not greater than

C x= 0   greater than

Step-by-step explanation:

because i did trial and error, i converted all the fractions into decimals until one of the conversions was equal to 2.444444444444...infinite

[tex]2 \frac{4}{9}[/tex] would be the correct answer.

This is not 2.4. This is "2.44444..." because of the line over the 4 after the decimal place (this applies for any decimal such as [tex]2.48\overline{47} = 2.484747474747...[/tex]).

The measurement of angle RST is 105

Answer:

Option C). 105°

Step-by-step explanation:

From the figure we can see a cyclic quadrilateral QRST

To find the measure of <RST

From the figure we can see that, angle RST is an obtuse angle.

The measure of angle RST is nearer to a right angle that is nearer to 90°

From the options we get the measure of angle RST = 105°

Answer:

=20.0

Step-by-step explanation:

We can first find the value of the angle at B using the sine formula.

a/sine A=b/Sin B

9/sin 15=12/sin B

Sin B=(12 sin 15)/9

Sin B=0.345

B=20.18°

Therefore angle C =180-(15+20.18)

=144.82°

a/Sin A=c/Sin C

9/Sin 15=c/Sin 144.82

c=(9 sin 144.82)/sin15

=20.0

Answer:C

Step-by-step explanation:4x _2y =64 because 8×8= 64

For this case we must find an equation equivalent to:

[tex]\frac {1} {4} x- \frac {1} {2} y = 8[/tex]

We add [tex]\frac {1} {2}[/tex] and on both sides of the equation:

[tex]\frac {1} {4} x = 8 + \frac {1} {2}y[/tex]

We multiply by 4 on both sides of the equation:

[tex]x = 32 + \frac {4} {2}y\\x = 32 + 2y[/tex]

squaring both sides we get

 4x-16=129

 4x=1296+16

 x=(1296+16)/4

  x=328 .

Answer:

x = 328

Step-by-step explanation:

The given equation is

[tex](4x-16)^{\frac{1}{2}}=36[/tex]

We need to find the solution of the given equation.

Taking square on both sides.

[tex]((4x-16)^{\frac{1}{2}})^2=(36)^2[/tex]

[tex](4x-16)^{\frac{2}{2}}=1296[/tex]

[tex]4x-16=1296[/tex]

Add 16 on both sides.

[tex]4x-16+16=1296+16[/tex]

[tex]4x=1312[/tex]

Divide both sides by 4.

[tex]x=\dfrac{1312}{4}[/tex]

[tex]x=328[/tex]

Therefore, the value of x is 328.

Answer: C

Step-by-step explanation:

Probability: the outcome you want (2) over the total number of outcomes (6).

Probability= 2/6= 1/3.

The probability of landing on 2 is 1/6 if the total number of outcomes is 6 and favorable outcomes are 1 option (C) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have a spinner shown in the picture.

Total number of outcomes = 6

{1, 2, 3, 4, 5, 6}

Total number of favorable outcomes = 1

{2}

P(landing on 2) = 1/6

Thus, the probability of landing on 2 is 1/6 if the total number of outcomes is 6 and favorable outcomes are 1 option (C) is correct.

Answer:

26,250

Step-by-step explanation:

25,000 + 5% = 26,250

:) please mark Brainliest

The Smiths' new car purchase price before taxes cannot exceed $23,809.52 considering they have $25,000 and need to pay a 5% sales tax on the purchase.

To calculate the maximum purchase price of the new car before taxes that the Smiths can afford, we need to account for the 5% sales tax they will have to pay on top of the purchase price. Since the Smiths have saved $25,000, this is the total amount they have available to pay for the car including the sales tax.

To find the purchase price before tax, call this price 'P'. The total cost including the sales tax will be P + 0.05P (which is the sales tax). This total cost must not exceed $25,000. Therefore, we can set up the following equation:

1.05P <= $25,000

Divide both sides of the equation by 1.05 to isolate P:

P <= $25,000 / 1.05

P <= $23,809.52

So, the purchase price of the Smiths' new car before taxes cannot exceed $23,809.52.

To find the simplified form of given expression

Let  (m/n) * (n/p) ÷ (p/q) can be written as,

(m/n) * (n/p) ÷ (p/q) =  (m/n) * (n/p) * (q/p)

 = (m * n * q)/(n * p * q)

 = (m * q)/(p * p)

Answer:

0.7557

Step-by-step explanation:

In this question use the Table of Standard Normal Probabilities for Negative z-scores and the Table of Standard Normal Probabilities for Positive z-scores

Where z=2.27 NORMDIST(2.27)=0.9884 (read from table for positive z-scores)

Where z=-0.73 NORMDIST(-0.73)=0.2327 (read from table for negative z-scores)

You know P(-0.73<z<2.27)= 0.9884-0.2327=0.7557

The probability that P(–0.73 < z < 2.27) is 0.7557.

The z score is used to determine by how many standard deviations, the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\where\ x=raw\ score,\mu=mean, \sigma=standard\ deviation,n= sample\ size\\\\\\[/tex]

From the normal distribution table, P(-0.73 ≤ z ≤ 2.27) = P(z < 2.27) - P(z<-0.73) = 0.9884 - 0.2327 = 0.7557

Answer:

The length is 16.1 ft and the width is 4.7 ft

Step-by-step explanation:

Let

x -----> the total length of the tables

y -----> the width of the tables

we know that

The area is equal to

[tex]A=xy[/tex]

[tex]A=75\ ft^{2}[/tex]

so

[tex]75=xy[/tex] -----> equation A

[tex]x=3y+2[/tex] -----> equation B

substitute equation B in equation A

[tex]75=(3y+2)y[/tex]

[tex]3y^{2} +2y-75=0[/tex]

Solve the quadratic equation by graphing

The solution is [tex]y=4.7\ ft[/tex]

Find the value of x

[tex]x=3(4.7)+2=16.1\ ft[/tex]

therefore

The length is 16.1 ft and the width is 4.7 ft

Answer:

The length and width of the serving table is 16.1 ft and 4.7 ft respectively.

Step-by-step explanation:

Consider the provided information.

Let the width of the table is x and length of the table is y.

The total length of the tables will be two more than three times the width.

This can be written as:

y = 2+3x

The area of the table is 75 ²ft

The area of rectangle is:

length × width = Area

Substitute width = x and length = 2+3x in above formula.

(x)(2+3x) = 75

2x+3x²-75 = 0

3x²+2x-75 = 0

The above equation is in the form of ax²+bx+c=0. Now use the quadratic formula to find the root of the equation.

[tex]x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Substitute a=3, b=2 and c=-75 in above formula.

[tex]x_{1,2}=\frac{-2\pm\sqrt{2^2-4(3)(-75)}}{2(3)}[/tex]

[tex]x_{1,2}=\frac{-2\pm\sqrt{904}}{6}[/tex]

[tex]x_{1,2}=\frac{-2\pm30.07}{6}[/tex]

[tex]x_{1}=\frac{-2+30.07}{6}[/tex]

Ignore the negative value of x as width should be a positive number.

[tex]x=4.7\ ft[/tex]

Now substitute the value of x in y = 2+3x.

y = 2+3(4.7)

y = 16.1 ft

Hence, the length and width of the serving table is 16.1 ft and 4.7 ft respectively.

Answer:

The function is defined when x > 0

Step-by-step explanation:

Functions with radicals are only undefined when the value in the radical is negative, because the root of a negative number is imaginary.  

We know the function is undefined when the denominator is equal to zero.  [tex]\sqrt{2x}[/tex] is equal to zero when x=0.

We also know that functions with radicals are undefined when the value in the radicals are negative, because the root of a negative number is imaginary.  .  [tex]8x^{2}[/tex] will always be positive, but [tex]2x[/tex] is negative when x < 0.

So the function is undefined when x = 0, and when x < 0.

Therefore it is defined when x > 0

Answer:

a. [tex]c(x) = 2x + 105[/tex]

b.  [tex]c(50) =\$205[/tex]

Step-by-step explanation:

The variable cost of $ 2 implies that for each manufactured calculator the total cost increases $ 2.

The fixed cost of $ 105 implies that regardless of the number of manufactured calculators there will always be a cost of $ 105.

If we call x the number of manufactured calculators then the total cost c(x) will be:

[tex]c(x) = 2x + 105[/tex]

Then, the cost of manufactured 50 calculators a day is:

[tex]c(50) = 2(50) + 105[/tex]
