A fishbowl shaped like a sphere is filled with water. The fishbowl has a diameter of 16 inches. Which measurement is closet to t
rjkz [21]

Answer:

A) 2144.66 in³

Step-by-step explanation:

A fishbowl shaped like a sphere is filled with water. The fishbowl has a diameter of 16 inches. Which measurement is closet to the volume of water in the fishbowl in cubic inches?

Volume of a sphere = 4/3πr³

Diameter = 16 in

Radius = Diameter/2 = 16 in/2 = 8 in

Volume of a Sphere = 4/3 × π × 8³

= 2144.66 cubic Inches

Option A.is correct

Which system of equations is equivalent to the following system? 3x + 5y = 29 x + 4y = 16 3x + 5y = 29 −x − 4y = 16 3x + 5y = 29
sp2606 [1]

Answer:

Option 3x+5y=29 and -3x-12y=-48 is the system of equations equivalent to the given system of equations 3x+5y=29 and x+4y=16

Step-by-step explanation:

Given system of equations  is 3x+5y=29 and x+4y=16

To find the equivalent system of equations to the given system of equations :

Option 3x+5y=29 and -3x-12y=-48 is the system of equations represents the given system of equations.

Because we can write the given equations as below

3x+5y=29 and x+4y=16

x+4y=16 rewritting as below

When multiply the above equation into (-3) we get

(-3)\times (x+4y)=16\times (-3)

-3x-4y=-48 as same as the equation x+4y=16 so we can say that they are equivalent

Therefore Option 3x+5y=29 and -3x-12y=-48 is the system of equations represents the given system of equations

Therefore 3x+5y=29 and -3x-12y=-48 is the system of equations equivalent to the given system of equations 3x+5y=29 and x+4y=16

What can you say about the y-values of the two functions f(x) = 3x -3 and<br> g(x) = 7x2 -3?
Elena-2011 [213]

9514 1404 393

Answer:

  • the y-values of g(x) are limited to values of at least -3, those of f(x) are not limited
  • the y-values are the same for two different x-values

Step-by-step explanation:

You can say lots of things about the y-values of these functions. A couple of observations are listed above. In addition, we can say the y-values of g(x) will be greater than those of f(x) for x-values not equal or between the x-values where the y-values are the same.
