Answer:
Step-by-step explanation:
Mode (most occurring) - 4
mean (average) - 8
median (middle number from least to greatest) - 4
The answer is 0.154 m
Step 1. Calculate the volume of gasoline tank (V) using the known mass (m) and density of gasoline (D).
D = m/V
⇒ V = m/D
D = 719.7 kg/m³
m = 45.0 kg
V = 45.0 kg/719.7 kg/m³ = 0.0625 m³
Step 2. Calculate the depth of the tank (d) using the known volume (V) of gasoline and width (w) and length (l) of the tank:
V = d * w * l
0.0625 = d * 0.900 * 0.450
0.0625 = d * 0.405
d = 0.0625 / 0.405
d = 0.154 m
This depends on the necessary number of copies.
ANSWER
EXPLANATION
The first equation is
The second equation is
We want to eliminate y, so we multiply the first equation by
We now subtract equation (3) from (2)
Multiply both sides by
Substitute into the first equation to solve for x .
Multiply to obtain
Multiply both sides by 2.
The solution is
