Answer:

<em>D.)</em> y=\frac{1}{7} g

Step-by-step explanation:

Yellow parakeets = y

Green parakeets = g

Blue parakeets = b

There are 7 times as many yellow as green, which leaves us with the following equation:

7y = g

We also know that there are 4 times as many green as blue - but this is just a distractor, this equation is irrelevant!:

4g =b

The proper equation to solve for is 7y=g!

To solve, we do the following:

7y = g\\*\frac{1}{7}\\y = \frac{1}{7} g

Which of the following is a solution of x² + 14x + 112 = 0? If necessary, round to the nearest hundredth.
Readme [11.4K]
To determine the solution of the quadratic equation, use the quadratic formula which states that,
                                x = ((-b  +/- sqrt (b² - 4ac)) / 2a
From the equation, a = 1, b = 14, and c = 112. Substituting these to the quadratic formula,
                               x = <span>((-14  +/- sqrt (14² - 4(1)(12)) / 2(1) = indeterminate
Thus, the equation does not a real number solution. </span>

Please help me with this.A rectangular field is
Karolina [17]
First, let's get the perimeter of the rectangle:
P=2W+2L
P=130m+210m
P=340m
Then, let's get the area of the bigger one:
A=WL
A=65m*105m
A=6825m^2

Then let's try using a rectangle with a smaller ratio:
P=100m+240m
P=340m
Then:
A=50m*120m
A=6000m^2

If you used a square:
P=170+170
P=340
A=WL
A=85^2
A=7225

There you have it. A rectangle with a smaller area with the same perimeter.
What does it show? The smaller the difference you get from width and length, the larger the area is.

The right rectangular prism shown below is made of equal-sized cubes. The side length of each cube is 2 1/2 inches. What is the
mr_godi [17]

The image of the right rectangular prism is missing, so i have attached it.

Answer:

volume of the right rectangular prism = 625 in³

Step-by-step explanation:

The rectangular prism is made of equal-sized cubes. Thus, let's first find the volume of 1 cube.

Formula for volume of one cube is;

V = a³

where

a is the length of one side of the cube

We are told that this length is 2½ inches

Thus;

a = 2½ = 5/2 inches

>> V = (5/2)³

>> V = 125/8 in³

Now, in the rectangular prism attached, if we count the number of cubes we have, it is equal to 40 cubes

Therefore, the volume of the prism is;

Volume of one cube × 40

>> volume of the prism = (125/8) × 40

volume of the prism = 625 in³
