Find the length of the circumference:
Circumference = 2 x pi x radius
Circumference = 2 x 3.14 x 7
Circumference = 43.96 kilometers
90 degrees is 1/4 of a circle ( 360/4 = 90)
Arc length = 43.96/4 = 10.99 kilometers
(Round answer as needed)
Answer:
area = 12.6 m²
Step-by-step explanation:
r = 4/2 = 2
area = πr² = (3.14)(2²) = 12.56 m²
Answers:
<h2>A, C, & E</h2>
Step-by-step explanation:
To see which ordered pairs work in the inequality, substitute the ordered pairs in for the variables. If you get a true statement, this means the pair is a solution to the inequality.
A. 3, 18
-3x + y <u>></u> 7
-3(3) + 18 <u>></u> 7
-9 + 18 <u>></u> 7
9 <u>></u> 7 Correct :)
3, 18 is a solution to this inequality.
B. -2, -3
-3(-2) + -3 <u>></u> 7
6 + -3 <u>></u> 7
3 <u>></u> 7 Incorrect :(
-2, -3 is not a solution to this inequality.
C. -1, 8
-3(-1) + 8 <u>></u> 7
3 + 8 <u>></u> 7
11 <u>></u> 7 Correct :)
-1, 8 is a solution to this inequality
D. 1, 9
-3(1) + 9 <u>></u> 7
-3 + 9 <u>></u> 7
6 <u>></u> 7 Incorrect :(
1, 9 is not a solution to this inequality.
E. 0, 7
-3(0) + 7 <u>></u> 7
0 + 7 <u>></u> 7
7 <u>></u> 7 Correct :)
0, 7 is a solution to this inequality.
<em>PLEASE MARK BRAINLIEST</em>
If you're going to write negative exponents, please enclose them inside parentheses:
12 / c^(-8)
12 8d^2
<span>12/c^-8d^2 becomes --------- - ---------
c^8 1
Here the LCD is c^8, so the above expression becomes:
12 c^8*d^2 12-(c^8)(d^2)
------- - ------------- = ---------------------
c^8 c^8 c^8</span>
Find the mean of 10 and 9. Wen you do that then you will have the median.
