Example: Set up proportions.

3/4 cups → 1 batch
x cups → 2 batches

x = 2(3/4) = 6/4 = 1 1/2 cups

3/4 cups → 1 batch
y cups → 9 batches

y = 9(3/4) = 6 3/4 cups

IRINA_888 [86]

Answer:

$60 for a noble fir, and $40 for a douglas fir

Step-by-step explanation:

Let x represent the number of noble fir trees

Let y represent the number of douglas fir trees

We can set up a system of equations to solve this problem

5x + 3y =  420  

12x + 9y = 1080      

We can use elimination method to solve this.  9 is a multiple of 3, so we'll multiply the first equation by -3 to get...

-15x - 9y = -1260

12x + 9y = 1080

Now add them together...

-3x = -180         now solve for x...

        x = 60

If x = 60, them

5(60) + 3y = 420        now solve for y

  300 + 3y = 420

      3y = 120

           y =  40

How many cubes with side lengths of 1/3 cm does it take to fill the prism?
user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = \frac{1}{3} cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 \frac{2}{3} = \frac{8}{3} cm

The height of prism (h) = \frac{2}{3} cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³   cm³

Or,  Volume of cube with length (l) = (\frac{1}{3})^{3}  cm³

Or,  Volume of cube with length (l) = (\frac{1}{27})  cm³

Again , Volume of prism  = \frac{1}{2}\times Length \times width \times height

Or, Volume of prism = \frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}

Or, Volume of prism = (\frac{8}{9})  cm³

<u>So , The number of cubes to fill prism  </u>

 The number of cubes × Volume of cube = Volume of prism

Or, x × (\frac{1}{27})  cm³ = (\frac{8}{9})  cm³

or   x = \frac{8\times 27}{9} = 24

Hence The number of cubes which fill the prism is 24  Answer

Ivory created a scaled copy of rectangle A.
9966 [12]

The scale factor that Ivory used to create their scaled copy is;

<u><em>Scale is 1 interval on graph represents 4 units of the rectangle. This is 1:4 ratio.</em></u>

  • From the given image, we can see that the y-axis of the rectangle has 3 intervals while the x-axis has 1 intervals

  • Now, from the image, we are told that the area of the scaled copy is 48 square units.

What this means is that the area of the triangle she is trying to represent with that graph is 48 square units.

  • Now, if one interval of the graph is x-units, then it means;

length; y-axis = 3x units

width; x-axis = x units

  • Area of a rectangle is given by;

Area = Length × width

Thus;

3x * x = 48

3x² = 48

x² = 48/3

x² = 16

x = √16

x = 4

<em>Thus, 1 interval on the graph represents 4 units of the rectangle.</em>
