Alexandra's drafting class is building a scale model of the school's courtyard. Alexandra chose to make a model of a campus oak tree for the assignment as shown. The tree is 10 yards tall and the base of the tree is 5 yards away from the edge of a park bench. She calculated that her oak tree model should be 0.4 yards tall. What is the distance, in yards, from the base of the model tree to the edge of the model bench?

Answers

Answer:

It's 0.20

Step-by-step explanation:

The distance between the base of the model tree to the edge of the model bench is  0.2 yard.

Examine the linear graph to find the slope , y-intercept, and write the equation for this linear relationship ​

Answers

Answer:

The slope of the line is: [tex]m=-\frac{1}{2}[/tex]

The y-intercept b = 3

The slope-intercept equation of the line is:  [tex]y\:=\:-\frac{1}{3}x+3[/tex]

Step-by-step explanation:

Taking two points from the given graph

(0, 3) and (6, 0)

Determining the slope m

The slope between (0, 3) and (6, 0) using the formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m is the slope between (x₁, y₁) and (x₂, y₂)

In our case,

(x₁, y₁) = (0, 3) (x₂, y₂) = (6, 0)

now substitute (x₁, y₁) = (0, 3) and (x₂, y₂) = (6, 0) in the slope formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{0-3}{6-0}[/tex]

[tex]m=-\frac{3}{6}[/tex]

[tex]m=-\frac{1}{2}[/tex]

Thus, the slope of the line is: [tex]m=-\frac{1}{2}[/tex]

Determining the y-intercept (b)

The slope-intercept form of the line equation is given by

[tex]y = mx+b[/tex]

where

[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept

From the graph, we can figure out the y-intercept by checking the value of y at x = 0.

If we closely check the graph, at x = 0, the value of y = 3

Therefore, the y-intercept b = 3

Slope-intercept Equation

We already know that the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

substituting b = 3 and m = -1/2

[tex]y\:=\:-\frac{1}{2}x+3[/tex]

Therefore, the slope-intercept equation of the line is:  [tex]y\:=\:-\frac{1}{2}x+3[/tex]

Stuff mart sells ice cream toppings in two different packages. Package one has eight blueberry toppings for $22. Package two has four blueberry and seven strawberry toppings for $22. Find the cost of each topping

Answers

Answer:

the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57

Step-by-step explanation:

The computation is shown below:

Let us assume the blueberry topping be x

And, the strawberry topping be y

Now as per the question

8x = $22

Divide by 2 to the both sides

4x = $11

x = $11 ÷ 4

= $2.75

And,

4x + 7y = $22

Now put the x value in the above equation

4 × (11 ÷ 4) + 7y = $22

11 + 7y = $22

7y = $22 - $11

7y = $11

y = $11 ÷ 7

= $1.57

Hence, the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57
