Answer:
Step-by-step explanation:
The formula for determining the volume of a sphere is given as
Volume = (4/3) πr³
where r is the radius and π is a constant whose value is 3.14
From the information given,
Diameter = 9.4 mm
Radius = diameter/2 = 9.4/2
= 4.7 mm
Volume of sphere = 4/3 × 3.14 × 4.7³
= 434.67 mm³
The formula for determining density is expressed as mass/volume
Mass = 3.475 g
Density = 3.475/434.67 = 0.008g/mm³

Step-by-step explanation:
Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1
Answer:
x - 8y = - 56
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = x + 7
Multiply through by 8 to clear the fraction
8y = x + 56 ( subtract 8y from both sides )
0 = x - 8y + 56 ( subtract 56 from both sides )
- 56 = x - 8y, that is
x - 8y = - 56 ← in standard form
