For Nina: 117.60 / 1414 = 0.083168317 For Ty: 148.50 / 1818 = 0.081683168 For Kim: 137.60 / 1616 = 0.085148515 Then Kim has the highest pay rate in dollars per hour with a total of 0.085148515 $ / h.
First you have to estimate.
$3.98 —>$4.00
$4.19 —>$4.00
$0.79 —>$1.00
Then we need to add.
4+4+1=9
So the answer is C, $9
Answer: <em>time = 55.48 years</em>
Explanation:
Given:
Principal amount = $10000
Interest rate = 2% p.a
Amount = $30000
We can evaluate the time taken using the following formula:
Solving the above equation, we get
Now taking log on both sides, we get;
<em>time = 55.48 years</em>
Answer:
The area of the shaded = 8 - 2π units²
Step-by-step explanation:
The area of the shaded portion = area square - area not shaded portion
Not shaded portion consists of two equal segments
∵ The side of the square = the radius of the circle = 2
∵ The measure of each angle of the square = π/2 (90° = π/2 rad)
∵ Area each segment = Area sector - area triangle
∵ Area triangle = 1/2 × (2) × (2) = 2 units²
∵ Area sector = (1/2)r²Ф ⇒ r = 2 , Ф = π/2
∴ Area sector = (1/2) (2)² (π/2) = π units²
∴ Area each segment = π - 2
∴ Area not shaded = 2(π - 2) = 2π - 4 units² ⇒ two segment
∵ Area square = 2 × 2 = 4 units²
∴ Area shaded portion = 4 - (2π - 4) = 4 - 2π + 4
= 8 - 2π units²
