You would use the volume of a cone formula ((1/3)(pi)(r^2)h) so it would be (1/3)(pi)(7^2)(24). That simplified to 392(pi) units^3. So the answer is c

Based on the graph, which equation represents the relationship between the height of trees (y) and the amount of rainfall (x)?

slega [8]

Given:

Given that the graph that shows the amount of rainfall( in centimeters) and the height of the trees( in meters)

We need to determine the equation that represents the relationship between the height of trees(y) and the amount of rainfall(x).

Slope of the equation:

The slope can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the points (20,10) and (40, 20) in the above formula.

Thus, we get;

$m=\frac{20-10}{40-20}$

$m=\frac{10}{20}$

$m=0.5$

Thus, the slope of the equation is 0.5

y - intercept:

The y - intercept of the equation is the value of y when x = 0.

Thus, from the graph, when x = 0, the value of y is 0.

Hence, the y - intercept is b = 0

Equation of the graph:

The equation of the given graph can be determined using the formula,

$y=mx+b$

Substituting the values, we get;

$y=0.5x+0$

$y=0.5x$

Thus, the equation that represents the relationship between the height of the trees (y) and the amount of rainfall (x) is $y=0.5x$

Hence, Option C is the correct answer.

The ratio of the number of cups of blue paint to the number of cups of red paint that Lara mixed to make a shade of purple paint

katrin2010 [14]

Answer:

Part A: Number of cups of blue paint are 3 that are mixed with each cup of red paint.

Part B: $\frac{1}{3}$

Part C: $8

Step-by-step explanation:

Given that:

The ratio of the number of cups of blue paint to the number of cups of red paint that Lara mixed to make a shade of purple paint is 3:1.

Part A:

The number of cups of blue paint = 3

The number of cups of red paint = 1

In sentence form, it can be written that:

Number of cups of blue paint are 3 that are mixed with each cup of red paint.

Part B:

3 cups of blue paint requires 1 cup of red paint.

$\frac{3}{3}=1$ cup of blue paint requires $\frac{1}{3}$ cup of red paint.

Here, unitary method is used.

So, $\frac{1}{3}$ cup of red paint should be added to each cup of blue paint to make shade of purple.

Part C:

6 cups of blue paint are purchased for $48.

1 cup of blue paint is purchased for $\frac{\$48}{6} = \$8$
