1 trillion is 10^9.
Thus, 21 1/2 trillion is 21 1/2 times 10^9, or 2.15 times 10^10
Hope this helps. If not, ask for clarification.
Answer:
π/90 or 0.0035 units
Step-by-step explanation:
equation: <em>length of the arc = ∠of the angle/360 * circumference</em>
Substitute: <em>S = 0.4/360 * 10π</em> --> C = 2πr
Simplify: S = 1/900 * 10π
Simplify: S = π/90 ≈ 0.003489 units
Answer:
Step-by-step explanation:
AD = DC and BE=EC ⇒
DE = 1/2AB
- 4x + 1 = 1/2(11x - 25)
- 2(4x + 1) = 11x - 25
- 8x + 2 = 11x - 25
- 11x - 8x = 2 + 25
- 3x = 27
- x = 27/3
- x = 9
DE = 4*9 + 1 = 36 + 1 = 37
Mark saved $1.20 daily.
Carlos saved $1.50 daily.
Let M = total saved by Mark.
1.20/1.50 = M/(11.40)
Solve for M
Given:
To find:
The value of x.
Solution:
We have,
By cross multiplication, we get
Isolating variable terms, we get
Divide both sides by 4.
Therefore, the solution of the given equation is x = 0.25.
