Your equation would look like this . . .

n/-9 + 10 = 11

*solve by subtracting 10 from both sides, and then multiplying both sides by -9

n = (11 + 10)*-9 = -9

<u><em>n = -9</em></u>

So the division of a number and -9 or
x/-9

+10=11 or

(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9

Asphere has a diameter of 10 in. What is the volume of the sphere?

Pavel [41]

Answer: $\frac{500}{3}$ π $in^{3}$

Step-by-step explanation: diameter=10 in

radius= $\frac{diameter}{2}$ = $\frac{10}{2}$ =5 in

volume= $\frac{4}{3}$ $r^{3}$

= $\frac{4}{3} X 5^{3}$ x π = $\frac{500}{3}$ π $in^{3}$

a rectangular pool has an area of 640 square feet. the is 12 feet shorter than the width. the length of the pool is feet and the

Ray Of Light [21]

Given:

Area of rectangular pool = 640 square feet

The length is 12 feet shorter than the width.

To find:

The length and width of the pool.

Solution:

Let width of the pool = x feet

Then, Length of the pool = (x-12) feet

Area of a rectangle is

$Area=length\times width$

$Area=(x-12)\times x$

Area of pool is 640 square feet. So,

$(x-12)x=640$

$x^2-12x-640=0$

Splitting the middle term, we get

$x^2-32x+20x-640=0$

$x(x-32)+20(x-32)=0$

$(x+20)(x-32)=0$

Using zero product property, we get

$x=-20,32$

Dimensions cannot be negative. So, x=32.

Now,

Width of the pool = 32 feet

Length of the pool = 32-12 = 20 feet

Therefore, the length of the pool is 20 feet and width is 32 feet.
