Answer:
Slope = 7.2 g/mL
Step-by-step explanation:
Density = mass/volume
Density is also the slope of the relationship between mass and volume.
When a graph between mass and volume is plotted, its slope gives the density of the object.
If the density is 7.2 g/mL, it would mean that the slope is 7.2 g/mL. Hence, this is the required solution.
The right equations are a+c=30 (total number of people) and 8a+c=100 (total amount of money). So answers B and D cannot be right.
a+c=30 can be rewritten as c=30-a and filled into the second one:
8a + 30-a = 100 => 7a = 70 => a=10
That leaves answer A as the right one.
We are given that 9/10 of the state land is about 45
million acres of farm. Therefore about 1/10 of the state land is not made up of
farms, therefore:
1/10 = 0.1
9/10 = 0.9
0.9 (state land) = 45 million acres
state land = 50 million acres
Hence,
not farmland = 0.1 * 50 million acres
not farmland = 5 million acres
