The diameter of a cookie is 2 inches. If pico’s 3.14, what is the area of the cookie, rounded to the nearest 10th?
Amanda [17]

For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

A = \pi * r ^ 2

Where:

r: It is the radius of the circle

According to the data we have:

r = \frac {2} {2} = 1 \ in

Thus, the area of the cookie is:

A = \pi * (1) ^ 1

We have \pi = 3.14

A = 3.14 * 1\\A = 3.14

We round:

A = 3.1

Thus, the area of the cookie is 3.1 \ in ^ 2

Answer:

3.1 \ in ^ 2

a clothing store office very often various promotions to attract customers but wants to maintain the same amount of profit to do
vova2212 [387]

Since 3 neckties will be out from the store, so you need to know how much is the cost of 3 ties.

$59.99 x 3 = $179.97 and divide it by two because the costumer will only pay for 2

$179.97 / 2 = $89.99 is the new price

Mark up = 89.99 – 59.99 = $30.00

% mark up = [(89.99/59.99) -1] * 100

= 50%

Jackson purchased some power tools totaling $1,543 using a six month deferred payment plan with an interest rate of 23.76%. He d
skad [1K]
Suppose he makes the payment with two equal annual instalments, the present value of the amount he is owing is $1,543 , the interest rate is 23.76% = 0.2376.

The amount of payment he makes in two of the periodic payments is given by:

PV = P\left( \frac{1-(1+r)^{-n}}{r} \right) \\  \\ \Rightarrow1,543=P\left( \frac{1-(1+0.2376)^{-2}}{0.2376} \right) \\  \\ =P\left( \frac{1-(1.2376)^{-2}}{0.2376} \right)=P\left( \frac{1-0.6529}{0.2376} \right) \\  \\ =P\left( \frac{0.3471}{0.2376} \right)=1.4609P \\  \\ \Rightarrow P= \frac{1,543}{1.4609} =1,056.20

Therefore, in 2 years, the amount he has paid for the tools is 2(1,056.20) = 2,112.40
