Answer:
After 900 minutes
Step-by-step explanation:
when we convert the velocities of the ships into miles/ min we get
The equations determining the distances of the ships from the port M (set at x=0) are
(for 45mph ship)
(for 36mph ship)
The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.
Answer:
each side is 36
Step-by-step explanation:
144÷4=36
You have to use the Pythagorean theorem because it is a right triangle. Consequently it is the square root of 12 squared plus 17 squared or approximately 20.81
The total length of a boundary defines the perimeter of an equilateral triangle.
<h3>What is the Perimeter of an Equilateral Triangle?</h3>
- The total of the three sides makes up the perimeter of an equilateral triangle.
- The following fundamental characteristics define a triangle as being equilateral:
- The three sides are equal.
- There is a 60° angle between all three.
- The sides of the triangle PQ = QR = RP in the following illustration have equal lengths.
- The triangle's angles are also equal in addition to this. An equilateral triangle is what this is.
- An equilateral triangle's perimeter is now equal to 3a, where a denotes one of the triangle's sides.
- Perimeter of Equilateral Triangle Formula : P = 3a, where 'a' stands for one of the triangle's sides, is a simple formula for calculating an equilateral triangle's perimeter. An equilateral triangle has three equal sides, hence the sum is equal to three equal sides, or 3a.
- Additional equilateral triangle formulas include the following: When we need to determine a triangle's height from its sides, we can apply the following formula: Equilateral Triangle Height = (3a)/2
- The semi-perimeter of an equilateral triangle must be determined in a few situations. Half of a perimeter, or semi-perimeter, is equal to 3a/2, which is derived using the formula semi-perimeter = (a + a + a)/2.
