Answer:

2513 miles

Explanation:

\sf Length \ of \ arc = \dfrac{\theta}{360} * 2\pi r

Here given:

∅ = 36°

radius = 4000 miles

Insert following:

\sf \rightarrow  \dfrac{36}{360} * 2\pi (4000)

\sf \rightarrow  800\pi \  \ \ (in \ terms \ of \ \pi )

\sf \rightarrow  2513.3 \ \ (rounded \ to \ nearest \ tenth)

\sf \rightarrow  2513 \ \ (rounded \ to \ nearest \ mile)

I wanna know the answer and steps to how to do this
Elanso [62]
Recognize that the triangle is isosceles, so the two side lengths are equal.

b = 2√2

Recognize it is a right triangle, so you can use the Pythagorean theorem to compute the length of "a".

a^2 = (2√2)^2 +(2√2)^2
a^2 = 8 +8 = 16
a = √16
a = 4

The new ranking functions make it easy to include a column in a result set that provides the sequential ranking number of each r
arlik [135]

Answer:

Partition

Step-by-step explanation:

Partition in mathematics is a way of calculating maths problems that involve enormous numbers by halving or ranking them into smaller units so they’re straightforward to work with. For instance, rather than adding up digits in a column,

86

+32

118

You can rank these numbers into units, like this…

80 + 6 + 30 + 2

Rearrange and the tens up

80+30+6+2=118

Which expressions are equivalent to -6n+(-12)+4n
GaryK [48]

Answer:

-2n - 12

Step-by-step explanation:

Combine like terms. Note that each term has one variable (n). Also note  that one negative sign and one positive sign results in a negative sign.

-6n + (-12) + 4n = -6n  + 4n - 12 = -2n - 12

-2n - 12 is your answer
