A visual example of this is one my mother showed me. She drew a circle and laid out a piece of yarn around it so that it imitated the perfect shape of the circle. She laid out another piece that was as long as the circle's radius. She wrapped the longer piece around the shorter one, and I saw that it could wrap around it three times and still have at least 0.14 units left. I'm not sure if this helps, but the circumference of this circle is 18.84 cm ^2. I hope I answered your question.

Keisha has a total of $6000 to invest in two accounts for 1 year. One account pays 5% simple interest and the other pays 6% simp

adoni [48]

Answer: He invest $2500 in account with rate of interest 5% and invest $3500 in account with 6% of interest so that the total interest earned is $335.

Step-by-step explanation:

Given: The rate of interest for account 1= 5%=0.05

The rate of interest for account 2= 6%=0.06

Let P be the Principal amount Keisha invested in the account with 5% interest .

Then the amount she will invest in account with 6% interest= 6000-P

Time = 1 year

The simple interest is given by:-

$S.I.=Prt$

Simple interest for account 1= $P(0.05)(1)=0.05P$

Simple interest for account 2= $(6000-P)(0.06)(1)=360-0.06P$

According to the question,

Total Interest =$335

$\Rightarrow0.05P+360-0.06P=335\\\Rightarrow\ -0.01P=335-360\\\Rightarrow\ -0.01P=-25\\\Righgtarrow\ P=2500$

So, he invest in account with 5% interest= $2500

He invest in account with 6 % interest=$6000-$2500=$3500

What is the circumference of this circle r= 2km

gladu [14]

Answer:

6.28 km

Step-by-step explanation:

The formula for circumference is C = 2πr. Just plug in the radius. C = 2π2. 2 times 2 is 4. So, multiply 4π, which is 6.283185307 (rounded to the nearest billionths). Generally, you are supposed to round to the nearest hundredth. The 3 would round the 8 down, leaving 6.28. The unit used to measure the radius, so unless told otherwise by the problem, stick to km. This results in 6.28 km being your final answer.

(3x - 2y) / (z + 4)........x = 1, y = -2, z = 3
now we start subbing
