Answer:
D ≈ 0.925926 g/cm³
Step-by-step explanation:
Density = Mass / Volume
Step 1: Define
M = 25 g
V = (3 cm)³ = 27 cm³
D = ?
Step 2: Substitute and Evaluate for Density
D = 25g / 27 cm³
D = 25/27 g/cm³
D ≈ 0.925926 g/cm³

therefore x+6=0
x = -6 hope this helps and you understand it.
Answer:
C)25.5
Step-by-step explanation:
The area of the rectangle is
A = l*w = 6*3.5 =21 m^2
The area of the triangle is
The height is the total height minus the height of the rectangle
A = 1/2 b*h = 1/2* 6 * (5-3.5)
1/2 (6) *1.5 = 4.5
Then add the ares together
A total = 21+4.5 = 25.5 m^2
Answer:
145
Step-by-step explanation:
If she did 87 sit-ups in 3 minutes then we would divide 87 by 3 so we know how many sit ups in each minute.
87 divided by 3 is 29
since we want to know how much she would complete in 5 minute we would have to multiply 29 by 5
29x5=145
hope that answers ur question
