$Solving \ an \ equation \ means \ finding \ a \ value \ of \ a \ variable$ $that \ make \ the \ equation \ true.$

<span> $Each \ sides \ of \ the \ equation \ should \ be \ equal \ at \ all \ times.

$ </span><span> $Whatever \ we \ do \ to \ one \ side, has \ to \ be \ done \ on \ the \ opposite \ side.$ </span>

Fifty metal spheres, each with a radius of 2 cm, are melted. The melted solution is poured into a box. What is the volume of all

bazaltina [42]

Answer:

<h2>The first option is correct 1675.5 cm^3</h2>

Step-by-step explanation:

Step one:

we are given the radius as

r=2cm, and the number of spheres is 50 in numbers

let us find the volume of one sphere and multiply the area by 50 to get the volume of the 50 spheres

Step two:

$volume=4/3 \pi r^3$

$volume=4/3*3.142 *2^3\\\\volume=100.5/3\\\\volume=33.5$

The volume of one sphere is 33.5in^3

Hence the volume of the 50 spheres will be

=33.5*50

=1675.7cm^3 approx.

25. The width of a rectangle is (x+1) and the length is (X-6). What is the length and width of the rectangle if the area is

Elis [28]

Answer:

x=−4 or x=9

Step-by-step explanation:

1- As we know the formula for Area of rectangle = length x width

2- Multiply given width = (x+1) with length = (x-6)

3-Equation will be (x+1)(x-6) = 30

4- Solving x^2−5 x−6 = 30

5- x^2−5 x -36 = 0

6-Factor left side of equation.

(x+4)(x−9)=0

Set factors equal to 0.

x+4=0 or x−9=0
