Answer:

Step-by-step explanation:

Area of a Rectangle: A = lw

Since our l is 3 and our w is 4, we plug them in:

A = 3(4)

A = 12

Alternatively, we count the squares in the rectangle to get 12 as our answer.

Simply Savings Bank offers a simple interest rate of 10% per year. Compound Capital Bank offers an interest rate of 8% per year

d1i1m1o1n [39]

Answer:

She should choose the Simply Savings Bank, since she'll earn around 2 dollars more in comparison to the other bank.

Step-by-step explanation:

A simple interest rate account yields a return that follows the formula below:

$return = C + C*r*t$

Where C is the invested money, r is the interest rate and t is the elapsed time in years.

While a compound interest rate account yields a return that follows the formula below:

$return = C*e^{r*t}$

Therefore for the Simply Saving Bank she'll earn:

$return_{1} = 200 + 200*0.1*5\\return_{1} = 200 + 100\\retrun_{1} = 300$

While the Capital Bank she'll earn:

$return_2 = 200*e^{0.08*5}\\return_2 = 200*e^{0.4}\\return_2 = 200*1.49182\\return_2 = 298.364$

She should choose the Simply Savings Bank, since she'll earn around 2 dollars more in comparison to the other bank.

An arc of a circle measures 80 degrees and the length of 88pie cm. what is the diameter?

kondor19780726 [428]

If 80° ------> 88π cm
Then 360° ------> x cm

So:

x = (88π x 360) ÷ 80
x = 396 π (lenght of the circle)

The relationship of Lenght of circle and its diameter is:

L = d .π

replacing L:
396 π = d.π ----> d = 396 cm <---- here is your answer

Find the area of segment CED given the following information:

Hitman42 [59]

Area of sector CAD = 72 / 360 x pi x 6^2 = 7.2pi = 22.6195 in^2

Therefore, area of segment CED = 22.6195 - 17.18 = 5.44 in^2
