An equilateral triangle has has an era of 43.5 square feet the height is 8.5 feet what is the Perimeter of the triangle
enot [183]

Answer:

30.7 ft

Step-by-step explanation:

<em>An equilateral triangle with area 43.5 has a height of 8.68 not 8.5</em>

<em>I will do the problem as written even though it is not a possible equilateral triangle</em>

<em>---------------------------------------------</em>

a = (1/2)bh

43.5 = (1/2)b(8.5)

43.5 = 4.25b

b = 43.5/4.25

b = 10.2352941176

-----------------------

p = 3b

p = 3 * 10.2352941176

p = 30.7058823528

~ 30.7 ft

Consider the quadratic function f(x) = –2x2 5x – 4. the leading coefficient of the function is?
evablogger [386]

Answer:

\text{-2 is the leading coefficient of the quadratic equation }f(x)=-2x^2+5x-4

Step-by-step explanation:

Given the quadratic function

f(x)=-2x^2+5x-4

we have to find the leading coefficient of given quadratic equation.

\text{The general form of quadratic equation is }ax^2+bx+c=0

The coefficient of x^2 i.e a is known as the leading coefficient.

Comparing given equation with the standard equation, we get

a=-2

\text{Hence, -2 is the leading coefficient of the quadratic equation }f(x)=-2x^2+5x-4

The difference of two supplemtary angles is 58 degrees. Find the measures of the angles
erik [133]

Answer:

The measure of the angles are 61° and 119°

Step-by-step explanation:

Let the first angle = x°

let the second angle = y°

The sum of two supplementary angles = 180°

x° + y° = 180° ----- equation (1)

based on the given question; "the difference of two supplementary angles is 58 degrees."

x° - y° = 58° ------- equation (2)

from equation (2), x° = 58° + y°

Substitute the value of x into equation (1)

(58° + y°) + y° = 180°

58 + 2y = 180

2y = 180 -58

2y = 122

y = 122 / 2

y = 61°

The second angle is given by;

x° = 58° + y°

x = 58° + 61°

x = 119°

Thus, the measure of the angles are 61° and 119°

A book was on sale for 40% off its original price. If
Kruka [31]

Answer:

Option C: $30 is the original price of book.

Step-by-step explanation:

Let the original price of book be x

Given that:

Sale price = x - 40% of x

As it is given that the sale price was $18

So,

$18 =  x - 40% of x

By simplifying:

$18 = x - 0.4x

$18 = 0.6x

Dividing both sides by 0.6:

x = $18/0.6

x = $ 30

So the original price of book will be $30

i hope it will help you!
