Answer:

l = p - 2w / 2

Step-by-step explanation:

You can make your own problem and plug it in. I substituted 5 for w and 6 for l. That means the perimeter would be 22. Now plug those numbers into all the problems. The one that gives you the correct answer is the top right answer.

6 = 22 - 5 / 2

Convert 0.533333... to a fraction. (only the 3 is repeating) Please show the work!!

Let x = 0.5333333333 ...

So 100x = 53.3333333333 ...
and 10x = 5.3333333333 ...
---------------------------------
90x = 53 – 5 = 48.

So x = 48/90 = 8/15 after reduction to lowest terms (by factor of 6)
0.3333... = ⅓. and that 0.5 = ½.

So 0.533333... = 0.5 + 0.0333333...0.5 + 0.3333.../10 = 1/2 + (1/3)/10 = 1/2 + 1/30 = 16/30 = 8/15

Answer:

p = 4

Step-by-step explanation:

Given equation:

$x^2+(p-3)y^2-4x+6y-16=0$

Standard equation of a circle:

$(x-a)^2+(y-b)^2=r^2$

(where $(a,b)$ is the centre of the circle, and $r$ is the radius)

If you expand this equation, you will see that the coefficient of $y^2$ is always one.

Therefore, $p-3=1$

$\implies p=1+3=4$

Additional information

To rewrite the given equation in the standard form:

$\implies x^2+y^2-4x+6y-16=0$

$\implies x^2-4x+y^2+6y=16$

$\implies (x-2)^2-4+(y+3)^2-9=16$

$\implies (x-2)^2+(y+3)^2=16+4+9$

$\implies (x-2)^2+(y+3)^2=29$

So this is a circle with centre (2, -3) and radius √29

the lenght of the longer leg of a right triangle is 9 ft longer than the lenght of the shorter leg x. The hypotenuse is 9 ft sho

trasher [3.6K]

Answer:

see below

Step-by-step explanation: 5 23 8 03

the lenght of the longer leg of a right triangle is 9 ft longer than the lenght of the shorter leg x. The hypotenuse is 9 ft shorter than twice the lenght of the shorter leg.

shorter leg = x

longer leg = x + 9

hypotenuse = 2x - 9

Pythagorean theorem = a² + b² = c²

shorter-leg² + longer-leg² = hypotenuse²

x² + (x+9)² = (2x - 9)² solve for x

x² + (x+9) (x+9) = (2x - 9)(2x - 9)

x² + (x²+18x+81) = (4x² - 36x + 81)

(2x²+18x+81) = (4x² - 36x + 81)

0 = 2x² -54x

0 = x(2x - 54)

0 = x and 0 = 2x -54

54 = 2x

27 = x

shorter leg = 27

longer leg = 36

hypotenuse = 45

divided all the values by 9 and you get a 3, 4, 5 right triangle, so the answer checks correct

How is 24 not a square number

Naily [24]

Because the closest square number is 5 which results in 52=25 therefor you cannot get the perfect square of 24
