irina1246 [14]

Answer:

We need to put $801.88 amount in the bank.

Step-by-step explanation:

given that

t=3 yr

Need amount $850 after 3 yr so P= $850

Interest rate=2%

We know that for simple interest

P=A\left(1+\dfrac{rt}{100}\right)

Where r is the Interest rate,t is the time,A is the present amount and P is principle amount after t time.

Here given that  P= $850

So now putting the values

850=A\left(1+\dfrac{2\times 3}{100}\right)

So A=$801.88

We need to put $801.88 amount in the bank.

Calculate the area of the composite figure.<br> 9 in<br> 5 in<br> 18 in<br> 5 in<br> 17 in
denpristay [2]

Answer:

Let's split the figure first:

9 x 5 = 45(area of small rectangle on top)

18 - 5 = 14(height)

17 - 9 = 8(width)

14 x 8 = 112(area of rectangle in the middle nearly)

18 - 5 = 14(base)

5(base 1) + 14(base 2) = 19

17 - 9 = 8(height)

19 x 8 = 152

152 divided by 2( x 1/2) = 76(area of a trapezoid on the side)

Now let's add all the given areas:

45 + 112 + 76 = 233 in^2 is your answer.
