Let m = measure of each interior angle of a regular polygon
It turns out that
m = [180*(n-2)]/n
where n is the number of sides
We have n = 9 sides, so
m = [180*(n-2)]/n
m = [180*(9-2)]/9
m = [180*7]/9
m = 1260/9
m = 140
Each interior angle is 140 degrees
Answer: D) 140
Answer:
The correct answer is 64
Step-by-step explanation:
we know that,
volume =4x
=4×4×4
=64

Ok
y=-0.04x^2+8.3x+4.3
when the rocket reaches the ground (when height=0, ie when y=0), then the rocket will land, find the x coordinate
set y=0
0=-0.04x^2+8.3x+4.3
use quadratic formula
if you have ax^2+bx+c=0, then
x=
a=-0.04
b=8.3
c=4.3
x=
x=208.017 or -0.516785
xrepresents horizontal distance
you cannot have a negative horizontal distance unless you fired and theh wind blew it backwards
therefor x=280.017 is the answer
208.02 m
Answer:
DP = 9/5
Step-by-step explanation:
DP + PE = DE
DP: x
PE: 4x + 7
DE: 10x - 2
x + 4x + 7 = 10x - 2
5x + 7 = 10x - 2
-5x = -9
x = 9/5
DP: 9/5
PE: 4(9/5) + 7
DE: 10(9/5) - 2
Check:
9/5 + 4(9/5) + 7 = 10(9/5) - 2
1.8 + 7.2 + 7 = 18 - 2
16 = 16
