Half of the distance from one side, through the middle, to the other side.

The radius is the distance from the center point of a circle to the "edge" of the circle. To calculate the circumference you use the formula: C=(D)(pi)...D stands for distance from one end of the circle to the other through the center point - basically the distance is the radius of any circle just doubled.

PLEASE SHOW YOUR WORK!!!<br><br><br><br><br><br> Solve for y: 3^3 + 14 y- (25y - 13) = y + 7y - 9y
Marina86 [1]
<h2 /><h2>⟹</h2>

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3^3+14*y-(25*y-13)-(y+7*y-9*y)=0

Equation at the end of step 1

((3³ + 14y) - (25y - 13)) - -y = 0

Pull out like factors :

40 - 10y = -10 • (y - 4)

Equation at the end of step3:

-10 • (y - 4) = 0

STEP4:

Equations which are never true:

Solve : -10 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

Solve : y-4 = 0

Add 4 to both sides of the equation :

y = 4

<h2>y = 4</h2>

2.5 X 10^5 divided by 1.0 X 10^10
bekas [8.4K]

Answer:

0.000025

Step-by-step explanation:

PEMDAS (Exponets first.)

10^5 = 100,000

10^10 = 10,000,000,000

rewrite

2.5 x 100,000 divided by 1.0 x 10,000,000,000

PEMDAS (multiplication next.)

2.5 x (10^5) = 250,000

1.0 x (10^10) = 10,000,000,000

rewrite.

250,000 divided by 10,000,000,000 = 0.000025

0.000025
