Answer:
independent
Step-by-step explanation:
Dependent equations graph as the <em>same line</em>. These lines are not the same, so the equations are independent.
___
However, the lines are parallel, so the equations are also <em>inconsistent</em>. There is <em>no solution</em> to this system of equations.
Answer:
A. 3.6×10^5 grams
Step-by-step explanation:
Multiply the number of people by the amount per person:
(1.8×10^3)(2×10^2 g) = 3.6×10^5 g
__
The applicable rule of exponents is ...
(10^a)(10^b) = 10^(a+b).
Answer:
5^3 = 125 cm^3
Step-by-step explanation:
The Volume of a cube is expressed as: V = s^3 - where s is the side of the cube and V is volume. Since all sides are 5cm long then the volume of the cube is 125 cm^3 OR it could also be expressed as 125 mL (since 1 cm^3 = 1 mL).
In the x quarts of 2% fat milk, there is 0.02x quarts of fat.
in the y quarts of 4% fat milk there is 0.04y quarts of fat.
together, there is (x+y) quarts of milk, and 0.24 quarts of fat.
the equations are:
x+y=9
0.02x+0.04y=0.24
multiply the first equation with 0.02: 0.02x+0.02y=0.18
subtract this new equation from equaition 2 to eliminate x:
0.04y-0.02y=0.24-0.18
0.02y=0.06
y=3
x=9-3=6
x is twice as much as y.
He used twice as much as the 2% fat milk than the 4% fat milk.
so the first choice is the correct answer.
