Answer:

Area of Shaded Region ≈ 0.23 cm^2

Step-by-step explanation:

Simple Question.

The diameter of the circle is 0.4 m, so the radius = 0.4/2 = 0.2 m.

The area of the circle = πr^2 = π(0.2)^2 = 0.04π

The area of the rectangle = 0.9*0.4 = 0.36

The area of the shaded region = 0.36 - 0.04π (π => 3.14) = 0.36 - 0.1256 = 0.2344 ≈ 0.23 cm^2

We were given the following details:

Car registration = $90

Car Insurance (annual) = $520

Home Insurance = $1020

Since we are to calculate for the monthly amount to budget for Car Insurance, we have:

\begin{gathered} CarInsurance(monthly)=\frac{CarInsurance\mleft(annual\mright)}{No\mathrm{}of\mathrm{}months} \\ CarInsurance(monthly)=\frac{520}{12}43.33\approx43.00 \\ CarInsurance(monthly)=\text{\$}43.00 \end{gathered}

herefore, the correct nanswer is A. ($43.00 per month)

From the above question, let's represent:

Number of candles sold for charity = x

The amount earned for charity = y .

Our equation is given as:

ŷ = 10x +41

Hence, x = 47

y = 10 × 47 + 41

y = 470 + 41

y = 511

The amount of money the charity should expect is 511
