Bernie has $16000 invested, part at 3% and the remainder at 5%. If the yearly interest on each investment is the same, how much

Snowcat [4.5K]

If the interest is the same for both accounts then:

.03x=.05(16000-x)

.03x=800-.05x

.08x=800

x=10000, since the interest is the same for both we can just double the interest from one investment to find the total interest earned each year...

.03(10000)2=$600.00

For questions 1 – 6, find the area of the circle to the nearest hundredth.<br> Any help appriciated!

Ganezh [65]

Step-by-step explanation:

The area of a circle is given by :

A = πr²

r is the radius of the circle

(4) Diameter = 22 cm

Since, radius = diameter/2

r = 11 cm

Now, area of the circle,

$A=\pi \times (11)^2\\\\A=380.13\ cm^2$

(5) Diameter = 30 cm

Since, radius = diameter/2

r = 15 cm

Now, area of the circle,

$A=\pi \times (15)^2\\\\A=706.85\ cm^2$

(6) Diameter = 4cm

Since, radius = diameter/2

r = 2 cm

Now, area of the circle,

$A=\pi \times (2)^2\\\\A=12.56\ cm^2$

So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
