P= 2I + 2W, -2I -2W
Solve for P by Simplifying both sides of the equations, then isolating the variable.
Answer:
7/3
Step-by-step explanation:
Let the two numbers be x and y which are relatively prime to each other.
a/b = 5/2
So you want the ratio of
(a + b) / (a - b)
- Take out a common factor of b
- numerator: b(a/b + 1)
- denominator: b(a/b - 1)
- Put them together
- The b's cancel out
- (a/b + 1) / (a/b - 1)
- but a/b = 5/2
- (5/2 + 1) / (5/2 - 1)
- Numerator: (5/2 + 2/2) = 7/2
- Denominator: 5/2 - 2/2 = 3/2
- numerator over denominator = 7/2 // 3/2 = 7/2 * 2/3 = 7/3
Answer: 7/3
Nice problem: Thanks for posting.
In a right triangle, the measure of one acute angle is 30 less than twice the measure of the other acute angle. Find the measure of each angle.
---
The sum of the 2 acute angles is 90 degrees.
x + y = 90
x = 2y-30
----
Substitute for "x" and solve for "y":
2y-30 +y = 90
3y = 120
y = 40
x = 90-y
x = 90-40
x = 50
Answer:
15
Step-by-step explanation:
If ∠BAC = 120°, then the area of sector BAC is equal to 120 / 360 = 1/3 of the entire circle.
