Which equation can be used to find the perimeter of a regular octagon with sides of length 12 m?

1 answer:

5 0

The basic definition of a perimeter is the boundary line of an object. For shapes and figures, this is basically the sum of the outermost sides that define the object. Since an octagon has eight sides, with each side measuring 12m, the perimeter can be obtained by multiplying 12 m by 8 sides, or in equation form:

P = 8(12)

Among the choices, this is letter B.

jenna is designing a statue for a monument. The torso needs to be 2.5 times the lenght of the head, and the legs need to be 1.6

klio [65]

T = 2.5h
l = t + 1.6

l = 2.5h + 1.6
5.2 = 2.5h + 1.6
5.2 - 1.6 = 2.5h
3.6 = 2.5h
3.6 / 2.5 = h
1.44 = h <===== length of head is 1.44 meters

Brian invests £8200 into his bank account.

Svetradugi [14.3K]

Answer:

£9184

Step-by-step explanation:

Interest = PRT/100

P = Price

R = Rate

T = time

First Let's find the interest for 2 years

$interest = \frac{8200 \times 6 \times 2}{100} \\ = 984$

So, the interest is £984

Now let's find the full amount he received after two years ,

$8200 + 984 = 9184$

Total Amount = £9184

Hope this helps you

Let me know if you have any other questions :-):-)

C) 0.179

Step-by-step explanation:

Since the trials are independent, this is a binomial distribution:

Recall:

Binomial Distribution --> $P(k)={n\choose k}p^kq^{n-k}$
$P(k)$ denotes the probability of $k$ successes in $n$ independent trials
$p^k$ denotes the probability of success on each of $k$ trials
$q^{n-k}$ denotes the probability of failure on the remaining $n-k$ trials
${n\choose k}=\frac{n!}{(n-k)!k!}$ denotes all possible ways to choose $k$ things out of $n$ things
