t - length of side of a triangle
The perimeter of a square:
The perimeter of a triangle:
We have the area of a triangle:
The formula of an area of an equilateral trinagle:
Substitute:
<em>multiply both sides by 4</em>
<em>divide both sides by </em>
The perimeter of a triangle:
Substitute to the formula of a perimeter of a square:
<em>divide both sides by 4</em>
The formula of a diagonal of a square:
Substitute:
Answer:
The approximate volume is
Step-by-step explanation:
we know that
The exact volume of the cylinder is
so
To find the approximate volume of the cylinder, substitute the term by the approximate value of and then multiply
so
Answer:
A) x > 7
Step-by-step explanation:
Since it's more than, the inequality would be >
Since it's >, that means it's an open circle
So,
x > 7
Since triangle ABC is a right triangle (90*), and angle ACB 45*, angle CAB must also equal 45*
Angles of triangle = 180=90+45+x
180=135+x
180-135=135-135+x
45=x
The break-even analysis lets you determine what you need to sell, monthly or annually, to cover your costs of doing business—your break-even point. The break-even analysis table calculates a break-even point based on fixed costs, variable costs per unit of sales, and revenue per unit of sales.
