5/8 - 5/24 denominators

leva [86]

Answer:

$\frac{5}{12}$

Step-by-step explanation:

The fraction 5/8 is equivalent to 15/24:

$\frac{5}{8}\times\frac{3}{3}=\frac{15}{24}$

Subtracting:

$\frac{15}{24}-\frac{5}{24}=\frac{10}{24}$

Reducing:

$\frac{10}{24}\div\frac{2}{2}=\frac{5}{12}$

What is the value of b for the following circle in general form? x2 + y2 + ax +by+c=0

liberstina [14]

Answer:

Step-by-step explanation:

<u><em>(1).</em></u> (x - <em>h</em>)² + (y - <em>k</em>)² = <em>r</em>²

where <em>(h, k)</em> are coordinates of a center of the circle with radius <em>r</em>

<u><em>(2).</em></u> ( a ± b )² = a² ± 2ab + b²

~~~~~~~~~~~~~~

( 1 , - 2 ) ; r = 3

( x - 1 )² + ( y + 2 )² = 3²

x² - 2x + 1 + y² + 4y + 4 = 9

x² + y² - 2x + 4y - 4 = 0

a = - 2

b = 4

c = - 4

Rolando is making buttons that are shaped like circles. Each button has an area of

shutvik [7]

Lets work backwards. π r2 = 62 cm. 62 / 3.14 = 17.75. Square root of 17.75 = 4.21. Okay, now using the radius of 4.21 we will use the formula C = 2 πr. C = 2 (3.14)(4.21) = 2 (13.22) = 26.44. So the circumference of each button is approximately 26.44 cm.

Sin A= ?<br>c/a<br>a/c<br>a/b<br>b/c

S_A_V [24]

Answer:

$\sin A = \frac{a}{b}$

Step-by-step explanation:

Given:

We took here a Right Angle Triangle,Δ ABC at angle B as 90°

Side opposite to angle A = a

Side opposite to angle B = b = Hypotenuse

Side opposite to angle C = c

To Find:

Sin A = ?

Solution:

Property of a Sine rule for a Right Angle Triangle.

$\sin A =\frac{\textrm{side opposite to angle A}}{Hypotenuse}\\\sin A =\frac{a}{b}$

∴ $\sin A = \frac{a}{b}$
