Melissa’s speed = 1lawn/8hours

1/8 + x = 1lawn/5hours

1/5 - 1/8 =

8/40 - 5/40 = 3/40 = 1/13.3333333

Jing can mow 1 lawn in 13.3333333 hours.

1/13.333333 = r/1

Jing could mow 7.5% of the lawn in 1 hour.

What is the frequency of the sinusoidal graph ?
disa [49]

Answer:

The frequency of the given sinusoidal graph is 4.

Step-by-step explanation:

The frequency of a sinusoidal graph is the number of cycles it completes in the interval 0 to 2π radians.

From the given sinusoidal graph it is noticed that the the graph complete its one cycle in the interval 0 to \frac{\pi}{2}.

If the complete its one cycle in \frac{\pi}{2}, then the number of cycles completed by the graph in the inteval 0 to 2π is

\frac{\pi}{2}\times frequency=2\pi

frequency=2\pi \times \frac{2}{\pi}

frequency=4

Therefore the frequency of the given sinusoidal graph is 4.

The number of tropical fish that an aquarium can hold depends on the volume of the fish tank. the interior dimensions of the fis
Stells [14]
<span>To figure the amount of tropical fish in the aquarium you multiple length*height*width to find the cubic centimeters of the tank, then divide that number by 10,000. 60*50*30=90,000 cubic centimeters. 90,000/10,000=9. 9 tropical fish could be places in a tank with those dimensions.</span>

I need to show how to find these solutions 1/4 and 3/4 by completing the square!
Arlecino [84]

Answer:

See explanation, and ask for more details if unclear!

Step-by-step explanation:

The perfect square of this equation is x^2-x+\frac{1}{4}, since the square would be (x-\frac{1}{2})^2. 1/4=4/16, meaning that you can set up the equation in the following way:

(x^2-x+\frac{1}{4})-\frac{1}{16}=0

(x-\frac{1}{2})^2=\frac{1}{16}

Take the square root of both sides:

x-\frac{1}{2}=\pm \frac{1}{4}

Add 1/2 to both sides:

x=\frac{1}{2}\pm \frac{1}{4}=\frac{3}{4}, \frac{1}{4}. Hope this helps!

I have 15a but I need 15b and 14
Naily [24]
14. For a prism, the volume is given by
.. V = Bh . . . . . . . . where B is the area of the base, and h is the height of the prism

For a pyramid, the volume is given by
.. V = (1/3)*Bh . . . . where B is the area of the base, and h is the height of the pyramid

The volume is proportional to the area of the base. If the dimensions of the base decrease linearly to zero at the height of the geometry as they do for pyramids and cones, then the volume formula includes a factor of 1/3.


15b. The volume of a pyramid is 1/3 that of a prism with the same base area and height.
