if a tv has a diagonal measurement of 55 and a height of 30, what is the tvs width? round to the nearest whole number
Sati [7]

Answer:

  46

Step-by-step explanation:

The geometry can be modeled by a right triangle. The diagonal measure is the hypotenuse, and the height is one leg. The width is the other leg, and can be found using the Pythagorean theorem.

__

<h3>Pythagorean theorem</h3>

The relation between the leg lengths (a, b) and the hypotenuse (c) is ...

  c² = a² +b²

Solving for b gives ...

  b = √(c² -a²)

<h3>application</h3>

In this problem, we have c=55 and a=30. Then the width of the TV is ...

  b = √(55² -30²) = √(3025 -900) = √2125

  b ≈ 46.098

The width of the TV is about 46.

2. A family buys a total of 32 tickets at a carnival. Ride tickets cost $1.50
Eduardwww [97]

Answer:

let the number of ride ticket be x and that of the food ticket be y

x+y=32

1.50x+3.25y=90

y=32-x

1.50x+3.25(32-y)=90

1.50x+104-3.25y=90

-1.75x=90-104

-1.75x=-14

x=14/1.75

x=8

y=32-x

y=32-8=16

I would appreciate if my answer is chosen as a brainliest answer

2+3x=-4(5+2x) solve for x, help please
Misha Larkins [42]

Answer:

x=-2

Step-by-step explanation:

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

Expand  \: the  \: parentheses:

2 + 3x =  - 4.5 - 4.2x

Simplify \:  the \:  arithmetic:

2 + 3x =  - 20 - 4.2x

Solve \:  by \:  distributing:

2 + 3x =  - 20 - 8x

Group  \: all \:  x  \: terms \:  on \:  the  \: left  \: \\  side \:  of  \: the \:  equation

2 + 3x =  - 20 - 8x

Add  \: 8x \:  to  \: both \:  sides:

2 + 3x + 8x =  - 8x  + 8x

Simplify  \: the \:  arithmetic:

11x + 2 =  - 20 - 8x + 8x

Group \:  like  \: terms:

11x + 2 =  - 8x + 8x - 20

Group \:  all  \: constants \:  on \:  the \:  right  \\  \: side \:  of  \: the \:  equation

11x + 2 =  - 8x + 8x - 20

Subtract \:  2  \: from  \: both \:  sides:

11x + 2 -  =  - 20 - 2

Simplify \:  the  \: arithmetic:

11x =  - 20 - 2

Simplify  \: the \:  arithmetic:

11x =  - 22

Isolate \:  the \:  x

11x =  - 22

Divide  \: both \:  sides \:  by  \: 11:

\frac{11x}{11}  =  \frac{ - 22}{11}

Simplify \:  the \:  fraction:

x =  \frac{ - 22}{11}

Find  \: the \:  greatest \:  common \:  factor  \\  \: of  \: the  \: numerator \:  and  \: denominator:

x =  \frac{ - 2.11}{1.11}

Factor \:  out  \: and \:  cancel  \: the \:  greatest   \\ \: common \:  factor:

x =  - 2

Thanks!!!!!!!
