Density = 0.8 g/cm³
Volume = 9000 cm³
D = m / V
0.8 = m / 9000
m = 0.8 x 9000
m = 7200 g
hope this helps!
The answer would be 1.6. The way you do this problem is you square the hypotenuse(in this case 11.56), then subtract the squared version on the side you do have (in this case 9). Then when you subrtact the two, find the square root of the difference (which would be 1.6 in this case).
Answer:
Step-by-step explanation:
(0, 1) (4, -2)
(-2 - 1)/(4 -0) = -3/4
Answer: It is D
Step-by-step explanation:
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
