Value of x (2x+43) (2x-3)

Answers

Answer:

-46

Step-by-step explanation:

2x+43=2x-3

We simplify the equation to the form, which is simple to understand

2x+43=2x-3

We move all terms containing x to the left and all other terms to the right.

+2x-2x=-3-43

We simplify left and right side of the equation.

0x=-46

0=-46

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

The answer to this problem is -46!

Touching angles have to equal  the full amount of degrees. This means oppisite angles are the same so 7/6, 5/8, 1/4, 2/3. This then means that 1/4 and 5/8 are the same. 3 and 5 would add up to the full amount of a flat line. 2 and 7 could as well, but diffrently (i dont remebr the terms lol). 6/8 would be supplementary, but wouldnt show that the lines are parrlele.

Find the value of two numbers if their sum is 19 and and their difference is 5

Answers

Answer:

7 and 12

Step-by-step explanation:

x - y = 5

y = (5+x)

x+ (5+x) = 19

2x +5 = 19

2x = 14

x = 7

           19-7 = 12

12 +7  = 19

12-7 = 5

answers- 7 and 12

if a + b =19
then, a - b =5
so, a= b + 5

if, a = b + 5
then, b + b + 5= 19
(2b) + 5 =1 9
19- a(5)= 14
b= 7
a+7=19
a= 12

A traffic yield sign is in the shape of an equilateral triangle. If each side is 36 inches,
what is the height of the sign to the nearest tenth of an inch?

Answers

Answer:

31.2 inches

Step-by-step explanation:

Draw a line representing the height of the triangle, and divide it into 2 triangles.

Apply Pythagoras Theorem on one of the smaller triangles first.

[tex]h = \sqrt{ {36}^{2} - {(36 \div 2)}^{2} } \\ h = \sqrt{ {36}^{2} - {18}^{2} } \\ h = \sqrt{972} \\ h = 31.17691...[/tex]

h = 31.2 inches (rounded to the nearest tenth)

Winnie's bedroom has an area of 120 square feet. The width of the room is 5/6 the length of the room. What are the dimensions of Winnie's bedroom?​

Answers

Answer:

x----------> the length of the room

y----------> the width of the room

we know that

x*y=120---------> equation 1

y=(5/6)x--------> equation 2

substitute 2 in 1

x*[(5/6)x]=120------> (5/6)x²=120-----> x²=120*6/5-----> x²=144

x=12 ft

y=(5/6)*12-----> y=10 ft

the answer is

the dimensions of Winnie's bedroom are

the length of the room is 12 ft

the width  of the room is 10 ft

Happy I can help

Answer:

48

Step-by-step explanation:

We are going to use trigonometry to solve for the wanted angle

Remember these are the trigonometric functions

( Remember SOH CAH TOA )

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

For angle Ф

we are given its adjacent side length (6) and the hypotenuse (9)

Adjacent and hypotenuse corresponds with the trig function Cosine

So we will use cosine to solve for the missing angle

( let x = missing angle )

( remember cosine = adjacent over hypotenuse )

[tex]cosX=\frac{6}{9} \\\frac{6}{9} =.66\\cos(x)=.66[/tex]

now we want to get rid of the "cos" on the x

To do so we take the inverse of cos ( arc cos ^-!1 ) and apply it to each side

so...

[tex]arcos(cos(x))=x\\arccos(.66)=48.1[/tex]

we're left with x = 48.1

A local company had revenues of $2,800 last year. They spent 1/4 of their revenues on marketing and 1/7 of the remaining money on upgrading their facilities. How much money did they have left after marketing and upgrading the facilities? Group of answer choices

Answers

Answer:

$1,800

Step-by-step explanation:

Given

Total revenue last year = $2,800

If they spent 1/4 of their revenues on marketing;

Amount spent on marketing = 1/4 * 2800

Amount spent on marketing = $700

Remaining money = 2800 - 700

Remaining money = $2100

If 1/7 of the remaining money is spent on upgrading their facilities, then;

Amount spent on upgrading facilities = 1/7 * 2100

Amount spent on upgrading facilities = $300

Total amount spent on marketing and facilities  = $700 + $300

Total amount spent on marketing and facilities  = $1000

Amount left = $2,800 - $1,000

Amount left = $1,800

Assume that Jordan Enterprises's radio broadcast license is renewable at the end of each 10-year term and management has provided evidence that approval of the renewal is highly probable. In this case, the broadcast license qualifies as anindefinite-life intangible asset and is not subject to amortization. Therefore, the firm carries the broadcast license at its original cost of $786,000.On December 31, 2015 the company noted substantial declines in radio advertising revenues over the past year due to expanded satellite radiosubscriptions, Internet broadcasts, and the use of iPod players. Based on the required annual review and consideration of the available impairment indicators, management believes that it is more likely than not that the broadcast license may be impaired. Therefore, the company must test the broadcast license for impairment. Similar broadcast licenses have been sold in auctions for $676,000.Assuming that renewal of the broadcast license is probable for this indefinite-life intangible asset, analyze the accounting for impairment and prepare the journal entries.1.) Conduct the impairment test indicated forindefinite-life intangible asset at the end of the year and determine the impairment loss, if any.
