A zookeeper is monitoring the population of birds. The flock needs to have exactly three times more females than males to thrive
KIM [24]

Answer:

The constraints are

0 < x\leq 20  and 0 < y\leq 60

Step-by-step explanation:

Let

x ----> represent the number of male birds

y ----> represent the number of female birds

we know that

The flock needs to have exactly three times more females than males to thrive

so

y=3x ----> equation A

The zoo only has room for a maximum of 20 male birds

so

0 < x\leq 20 ----> inequality B

we know that

The maximum number of male birds is 20

For x=20

substitute in the equation A

y=3(20)=60

so

The maximum number of female birds is 60

so

0 < y\leq 60 ----> inequality C

therefore

The constraints are

0 < x\leq 20  and 0 < y\leq 60

2. A drawing of a sailboat was made using a rectangle and two right triangles, as shown. What
Zarrin [17]

Answer:

  45 square centimeters

Step-by-step explanation:

The area of the triangle is given by ...

  A = (1/2)bh

where b is the base, 2 cm + 3 cm = 5 cm, and h is the height, 6 cm.

  A = (1/2)(5 cm)(6 cm) = 15 cm^2

__

The area of the rectangle is given by ...

  A = bh

where b is the base, 12 cm, and h is the height, 2.5 cm.

  A = (12 cm)(2.5 cm) = 30 cm^2

__

The area of the whole figure is the area of the triangle added to the area of the rectangle:

  drawing area = 15 cm^2 + 30 cm^2 = 45 cm^2

An oblique prism with a square base of edge length x units has a volume of One-halfx3 cubic units. Which expression represents t
lara [203]

Answer:one-half x units

Step-by-step explanation:

Given

Prism has a square base with length x\ units

If the volume of prism V=\frac{1}{2}x^3\ units

We know

Volume=base\ area\times height

Base area =x\times x=x^2\ units

height=\frac{Volume}{area}

height=\frac{\frac{1}{2}x^3}{x^2}

height=\frac{x}{2}\ units
