Answer:
6,7
Step-by-step explanation:
Answer:
1. d=m/v
=57.6/112.9
=0.51018601
=0.510g/cm³(3s.f.)
2. m=d×v
=1.8×54
=97.2g
3. v=m/d
=63.8/12.7
=5.02362205
=5.02cm³(3s.f.)
4. v=length×breath×height
=12×2×6
=144m³
216g=0.216kg
d=m/v
=0.216/144
=0.0015kg/m³
Step-by-step explanation:
density=mass/volume
mass=density×volume
volume=mass/density
*make sure the units are correctly placed.
*g/cm³, kg/m³
Answer:
84563 to 3 significant figure is 85,000.
Step-by-step explanation:
In this problem, we need to round off 84563 into 3 significant figures.
Significant figures are the digits that reliable and absolutely necessary to indicate the quantity of something. If a number expressing the result of measurement of something.
In 84563, it is eighty four thousand five hundred and sixty three. It is rounded off to 3 significant figures as 85,000.
Hence, 84563 to 3 significant figures is 85,000.
Answer:
y = -3/5x + 3/2
Step-by-step explanation:
begin with the slope-intercept form of a line which is: y = mx + b
'm' is the slope and 'b' is the y-intercept
the y-intercept is given but we need to find the slope
we can do so by using the points created by the x-and-y intercepts:
(0, 3/2) and (5/2, 0)
3/2 ÷ -5/2 = -3/5 (slope)
y = -3/5x + 3/2
