What's the perimeter of a semicircle with a diameter of 12 miles?

Answers

Answer 1

Answer: The perimeter, or circumference, of a circle is pi x diameter. A semicircle would just be 1/2pi x diameter. In this case, that would equal 6 pi. If you are supposed to use 3.14 as pi, then it would equal 18.84.

i will give all star to whoever and fan Logan plans to use $1200 to open a savings account with an annual interest rate of 1.25%. How much more interest will he earn over 5 years if he chooses a compound interest account that compounds interest quarterly instead of a simple interest account? Round your answer to the nearest cent. anyone who noes how to deal with finance and money?

Answers

Given:
Principal : 1200
interest rate: 1.25%
term : 5 years

Simple Interest = 1,200 * 1.25% * 5
S.I = 75
1,200 + 75 = 1,275

Interest compounded quarterly:
A = P (1 + r/4)^4t
A = 1,200 (1 + 0.0125/4)⁴ˣ⁵
A = 1,200 (1.003125)²⁰
A = 1,200 (1.064)
A = 1,276.80

Given a mean of 100, and a standard deviation of 5.3, what is the Z-score for 130?

Answers

Answer:

5.66038

Step-by-step explanation:

Given

Mean= μ=100

SD= σ=5.3

Z-score of 130= ?

The z-score of any value tells us that how many standard deviations that value is from the average or mean.

The Z-score of any data value is found by subtracting the mean from it and then dividing by the standard deviation.

z-score= (x- μ)/σ

z-score of 130= (130-100)/5.3

=30/5.3

=5.66038

(02.01)Seth has game and education apps on his tablet. He noticed that he has 5 game apps for every 2 education apps. Which of the following is another way to write this ratio?

Answers

Answer:

i) 5 to 2

ii) $(5)/(2)$

iii) 5 : 2

Step-by-step explanation:

Ratio is comparing the number of two things of the same kind.

The ratio can be written three different form.

i) a to b

ii) $(a)/(b)$

iii) a : b

Similarly, we can write 5 game apps for every 2 education apps.

i) 5 to 2

ii) $(5)/(2)$

iii) 5 : 2

you could write it as 5:2 (or 5/2) (game apps to education apps). alternately, you could write it as 2:5 or 2/5 (education apps to game apps).

Is 0.602 equvalent to 0.62

Answers

No.
0.602 = 0.6020 = 0.60200 etc
0.62 = 0.620 = 0.6200 etc
Adding zeros to the end of a decimal doesn't change the value, the order of the digits does.

No.. 0.62 is a larger number than 0.602
