Answer:
No diagram and no explanation what 9 is.
However, if it is an octagon with each side equal to 9 then
area = (# of sides * side^2) / (4 * tan (180 # of sides))
area = 8 * 9 * 9 / (4* tan (180 / 8)
area = 648 / 4 * 0.41421
area = 391.1059607446
answer is C
Step-by-step explanation:
Answer:
21.213
or
(21.213,0)
Step-by-step explanation:
y-intercept = 9
slope= -1/50x^2
I graphed it and it was a parabola and it hit the ground at this coordinate (21.213,0)
Answer:
Darnell can read 1,715 words in 7 minutes
Step by step Explanation:
1. I need to find out how many words he reads in 1 minute. Divide 735 by 3, my answer is 245
245
______
3)735
6 bring down the 3 to make 13
-_____
1 3
12 bring down the 5 to make 15
-______
1 5
15
___________
0
2. multiply 735 by 2 cause he reads 735 words in 3 minutes and we are tryna find out how many words he reads in 7 minutes. 3×2=6, so 735+735 (735×2) equals 1470
3. Add 245, for that extra minute that we missed. my answer is 1,715 words in 7 minutes
Answer:
37 1/2
Step-by-step explanation:
n - 2y = 3y- n/m,
find the value of n when y = 5 and m = -3
--------
n-2*5=3*5-n/-3
n-10=15+n/3
n-n/3=15+10
2n/3=25
2n=3*25
n=75/2
n=37 1/2 or 37.5
