Negative two and one-fourth divded by negative one and one-half

Bond [772]

Answer:

The answer is 3/2 or 1 1/2

Step-by-step explanation:

First, you have to make it as a improper fraction :

$- 2 \frac{1}{4}$

$= - \frac{( 2 \times 4) + 1}{4}$

$= - \frac{9}{4}$

$- 1 \frac{1}{2}$

$= - \frac{(1 \times 2) + 1}{2}$

$= - \frac{3}{2}$

Next, you can divide it by cutting out the common factor :

$- \frac{9}{4} \div - \frac{3}{2}$

$= - \frac{9}{4} \times - \frac{2}{3}$

$= - \frac{ 3}{2} \times - 1$

$= \frac{3}{2}$

$= 1 \frac{1}{2}$

The length of a rectangle is one unit more than the width. if the area is 30 square units find the dimensions of the rectanhgle

solmaris [256]

Width = w

Length = w + 1

Area = 30

w(w+1) = 30

w² + w = 30

w² + w - 30 = 0

w² + 6w - 5w - 30 = 0

w(w + 6) -5(w + 6) = 0

(w + 6)(w - 5) = 0

w = 5 or -6

Since the width cannot be negative, the width is 5 units.

Hence, the width is 5 units and the length is 6 units.

Simplify sin^2y/sec^2 y−1 to a single trigonometric function

liubo4ka [24]

Answer:

$\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y$

Step-by-step explanation:

We know that ${ \tan }^{2} y = { \sec }^{2} y - 1$

Also , ${ \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y }$

So ,

$\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y$
