A fish tank at an aquarium has a volume of 1,568 cubic feet and a depth of 8 feet. If the base of the tank is square, what is th
Mice21 [21]

Answer:

The base is a 14 by 14 square

Step-by-step explanation:

Here is why, if you take 1,568 and divide by 8 you get 196. Square rooting that would give you 14. You need to square root since from the question the equation is clearly x^2*8 = 1568

Big Bob’s Pizza is having a special on pizza and is offering two different choices:
Anna71 [15]

Answer:

The Choice N#1 will give more pizza for your money

Step-by-step explanation:

step 1

Find the area of one slice Choice #1

The area of the circle is equal to

A=\pi r^{2}

we have

r=22/2=11\ in ----> the radius is half the diameter

assume

\pi =3.14

The area of one slice is equal to

A=(1/8)\pi r^{2}

substitute

A=(1/8)(3.14)(11)^{2}

A=47.4925\ in^{2}

Divide the cost by the area

4.95/47.4925=0.10\frac{\$}{in^{2}}

step 2

Find the area of the entire personal pizza Choice # 2

The area of the circle is equal to

A=\pi r^{2}

we have

r=6/2=3\ in ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=(3.14)(3)^{2}

A=28.26\ in^{2}

Divide the cost by the area

3.75/28.26=0.13\frac{\$}{in^{2}}

therefore

The Choice N#1 will give more pizza for your money

What are the midline, amplitude, and period of the graphed sine function?
Sunny_sXe [5.5K]

The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π

<h3>Midline, Amplitude and Period</h3>

The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1

The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4

Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
