Which expression has a positive quotient?

svp [43]

Answer:

Only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.

Option A is correct.

Step-by-step explanation:

We will solve to find out Which expression has a positive quotient.

We know the division rule: $\frac{-a}{-b}=\frac{a}{b}$ and $\frac{-a}{b}=\frac{-a}{b}$

We will use these rules

1) Negative three-fourths divided by Negative two-thirds

$=\frac{-\frac{3}{4} }{-\frac{2}{3} }\\=-\frac{3}{4}\times -\frac{3}{2}\\=\frac{9}{8}$

The quotient is positive.

2) Negative StartFraction 1 over 8 EndFraction divided by 3 and one-fifth

$\frac{-\frac{1}{8} }{3\frac{1}{5} }\\=\frac{-\frac{1}{8} }{\frac{16}{5} }\\=-\frac{1}{18} \times \frac{5}{16}\\=-\frac{5}{288}$

The quotient is negative.

3) 2 and StartFraction 2 over 7 EndFraction divided by negative one-fifth

$\frac{2\frac{2}{7} }{-\frac{1}{5} }\\= \frac{\frac{16}{7} }{-\frac{1}{5} }\\=\frac{16}{7} \times -5\\=-\frac{80}{7}$

The quotient is negative.

4) Negative 6 divided by Five-thirds

$\frac{-6}{\frac{5}{3} }\\=-6 \times \frac{3}{5}\\=-\frac{18}{5}$

The quotient is negative.

So, only 1st option Negative three-fourths divided by Negative two-thirds has positive quotient.

Option A is correct.

the length of a rectangle is 3 cm less than the width. the area is 54cm^2. what is the length and the width of the rectangle?

GrogVix [38]

Answer:

The length of the rectangle is 6cm while the width is 9cm

Step-by-step explanation:

Here, we are interested in calculating the length and width of the rectangle.

Let the length of the rectangle be x cm

We are told that the length is 3 cm

less than the width, this means that the width is (x + 3) cm

The area of the rectangle is 54cm^2

Mathematically;

Area of rectangle = L * B

Thus;

x(x + 3) = 54

x^2 + 3x = 54

x^2 + 3x -54 = 0

x^2 + 9x -6x -54 = 0

x(x + 9 ) -6(x + 9) = 0

(x -6)(x + 9) = 0

x -6 = 0 or x+ 9 = 0

x = 6 or -9

Since length cannot be negative we choose x = 6cm

But width = x + 3 = 6 + 3 = 9cm

A factory that produces piano keys churned out 545,952 keys in 12 months. A piano requires 88 keys. How many pianos can be produ

Mariana [72]

Divide the total amount of keys produced by the amount of keys a piano requires to find the amount of pianos a factory made:

$545,952 \div 88 = 6204$

The factory made 6204 pianos in 12 months.

Because the question asks for the amount of pianos made for the first 3 months, we'll divide the total 12 months by the 3 months the question asks for:

$12 \div 3 = 4$

Now we'll divide the total amount of pianos made in 12 months by this number to find the pianos made in 3 months:

$6204 \div 4 = 1551$

1551 pianos were made in the first 3 months of production.
