The answer is B.
Because half of 35 and 30 is 32.5 so She can expect to grow 2.5 each year.
I hope this helps :)
The slope m = 3/2 and the y-intercept = ( 0, -6 ).
The graph is a solid line and shaded area below the boundary line since y is less than (3/2)x - 6.
<h3>What is the Graph the solution set of the inequality?</h3>
Given that:
3x -2y ≥ 12
First we write the inequality in slope intercept form y = mx + b.
Solve for y
3x -2y ≥ 12
-2y ≥ 12 - 3x
Now, divide each term by -2
y ≤ -6 + 3x/2
We re-arrange
y ≤ (3/2)x - 6
Using the slope intercept form y = mx + b. we can see that;
m = 3/2
b = -6
Hence, the slope m = 3/2 and the y-intercept = ( 0, -6 ).
The graph is a solid line and shaded area below the boundary line since y is less than (3/2)x - 6.

Answer: 60
Step-by-step explanation:
Using Heron's formula, we know that
Step 1: Calculate "s" (half of the triangles perimeter):
s = (a+b+c)/2
Step 2: Then calculate the Area:
Herons formula A = sqrt( s(s-a)(s-b)(s-c) )
So S = 36/2 = 18
so
So our final answer is the square root of 3600, which equals 60.
Answer:
He did not control for lurking variables and their impacts on the results of his experiment. Amount of sunlight and water received are two outside variables(or confounding variables) that may impact the growth of his plants and influence the results. He needs to apply the same amount of sunlight and water to each plant within a different planting soil in order to rule out the influence of those two variables and test the sole effect of the soil brand on the plant growth. Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received
Answer:
Option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.
Step-by-step explanation:
Given is the graph of Amount of water (in gallons) v/s Time (in seconds).
It is a linear graph whose general equation is given as follows:-
y=mx+b.
Where y = Amount of water, x = Time, m = slope, b = y-intercept (when time is zero).
Finding slope of line, m = (2.3 - 2.5)/(1 - 0) = -0.2 gallons per second.
Finding y-intercept of line, b = 2.5 gallons (at t=0).
Hence, option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.
