Answer:

34.54

Step-by-step explanation:

So the first thing you need to know is that to find the circumference of a circle is to use the formula 2 Pi R. R=Radius and to get the radius of a circle, the problem will either tell you or it will give you a diameter (11 inches). Divide the diameter by 2 and you will get 5.5. But if the radius is 5.5 then you multiply that by 2, you will get back to 11 inches. So the last step is to do 11 x 3.14 and you get 34.54.

The answer is 34.54. The formula for circumference of a circle is 2*pi*radius, or pi times diameter. (The radius is half of the diameter.) The diameter is 11, and we are using 3.14 for pi. 11 times 3.14 = 34.54.

I have no idea please help

22. Alternate angles

23. 4: ( $h_{b} = 2 \frac{a}{b}$ , substitute b with 10 and a with 20 and you get 4.)

24. 0.28: 0.12 + 0.60 = 0.72. Probability is always out of 1, so 1 - 0.72 should give you the probability of losing, which is 0.28.

What is the mean of this data set 82,105,247,119,94,202

Kazeer [188]

To find the mean, add the numbers, and divide by the amount of numbers there is.

(82 + 105 + 247 + 119 + 94 + 202)/6

Simplify. Remember to follow PEMDAS. First, add

(849)/6

Next, divide by 6

849/6 = 141.5

141.5 should be your answer

hope this helps

Investigate the difference between compounding annually and simple interest

Gennadij [26K]

Step-by-step explanation:

Simple interest formula

$A = P (1 + rt)$

Compound interest formula

$A = P(1 + \frac{r}{n})^{nt}$

$A = 5000 (1 + 0.025*1)\\A=5000(1.025)\\A=5125$

Simple interest is $125

. $A = 5000 (1 + \frac{0.025}{1})^{1*1} \\A=5000(1.025)\\A= 5125$

Compound interest is $125

c. the result for both a and b are the same

$A = 5000 (1 + 0.025*3) \\A=5000(1.075) \\A=5375$

the simple interest is $375

. $A = 5000 (1 + \frac{0.025}{1})^{1*3}] \\A=5000(1.025)^3 \\A=5000(1.077)\\A= 5385$

the compound interest is $385

f. the result compared, compound interest is $10 more than simple interest

$A = 5000 (1 + 0.02*6) \\A=5000(1.12) \\A=5600$

the simple interest is $600

$A = 5000 (1 + \frac{0.02}{1})^{1*6}] \\A=5000(1.12)^6 \\A=5000(1.9738) \\A= 9869$

the compound interest is $4869

i. the result from g and h, h is over 8 times bigger than g.

j. interest compound annually is not the same as simple interest, only for the case of a and b seeing that it is for 1 year. but for 2years and above there is difference as seen in c to h
