Answer:
B. 2340
Step-by-step explanation:
Interior angles of a polygon is given by
(n – 2)180 where n is the number of sides
(15-2) *180
13*180
2340
Answer:
S = v1 t1 = 7 t1 traveling downstream
S = v2 t2 = 5 t2 traveling upstream
7 t1 = 5 t2
7 (6 - t2) = 5 t2 since t1 + t2 = 6
42 - 7 t2 = 5 t2
t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs
S = 7 t1 = 7 * 2.5 = 17.5 mi
Also, S = 5 t2 = 5 * 3.5 = 17.5 mi
F(x)=x+c, where c is an arbitrary constant.
if c is positive then translation above
if c is negative then translation down
reflection of f(x)=x^2 across x-axis then
f(x)=-x^2
If you do 27-12 (which is 15) you add 15 to 13 and 20
.2 m^3 is 10 percent
.2 m^3 is 10 percent
.2 m^3 is 10 percent
.1 m^3 is 5 percent
therefore
.7m^3 is 35%
.6m^3 is 10%
.3 m^3 is 5%
so .9m^3 is 15 %
all in .9m^3 +.7m^3 = 1.6 m^3 will be sand
