Answer:

  • area of rectangle: 48 cm²
  • area of triangle: 18 cm²
  • shaded area: 30 cm²

Step-by-step explanation:

The area of a rectangle is given by the product of its length and width.

... A = LW

For your rectangle, the overall area is ...

... A = (12 cm)(4 cm) = 48 cm² . . . . rectangle area

___

The area of a triangle is half the product of its base and height. Your triangle is shown with a base of 9 cm, and its height is the height of the rectangle, 4 cm. The triangle area is ...

... A = (1/2)bh

... A = (1/2)(9 cm)(4 cm) = 18 cm² . . . . triangle area

___

The shaded area of the figure is the difference between the rectangle area and the triangle area. (The triangle is fully included in the rectangle, but is not shaded.) That difference is ...

... shaded area = rectangle area - triangle area

... shaded area = 48 cm² - 18 cm² = 30 cm² . . . . shaded area

Lincoln invested $49,000 in an account paying an interest rate of 6\tfrac{1}{8}6
Orlov [11]

Using compound interest and continuous compounding, it is found that Lincoln would have $15,856 more in his account than Eli.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

A(t) = P\left(1 + \frac{r}{n}\right)^{nt}

In which:

  • A(t) is the amount of money after t years.
  • P is the principal(the initial sum of money).
  • r is the interest rate(as a decimal value).
  • n is the number of times that interest is compounded per year.

Hence, for Lincoln, we have that the parameters are as follows:

P = 49000, r = 0.06125, n = 365, t = 20.

Hence the amount will be of:

A_L(t) = P\left(1 + \frac{r}{n}\right)^{nt}

A_L(20) = 49000\left(1 + \frac{0.06125}{365}\right)^{365 \times 20}

A_L(20) = 166787

<h3>What is continuous compounding?</h3>

The amount is given by:

A(t) = Pe^{rt}

For Eli, we have that r = 0.05625, hence the amount will be given by:

A(t) = Pe^{rt}

A_E(20) = 49000e^{0.05625 \times 20} = 150931

<h3>What is the difference?</h3>

It is given by:

D = A_L(20) - A_E(20) = 166787 - 150931 = 15856

Lincoln would have $15,856 more in his account than Eli.

At a store, bananas cost $0.68 per pound. How much will 4 1/2 pounds of bananas cost?
yulyashka [42]

Answer:

$3.06

Step-by-step explanation:

Based on the question that was given, we can see that for every *one* pound,  the cost of the bananas is $0.68.

Since we are looking for how much 4 1/2 pounds is worth, we can convert this to 4.5 and simply multiply $0.68 by 4.5, giving us a grand total of $3.06
