A perfect square is a number that is the square of a whole number. For example, 25 is a perfect square because it is the square

of 5: 5 × 5 = 25. How many perfect squares are greater than 0 but less than 1000?

Perfect squares are squares of integers and since 961 is the square of 31, it shows that there are 31 perfect squares  greater than 0 but less than 1000

<h3>What are perfect squares?</h3>

A perfect square is a number that is the square of a whole number. For instance, 36 is a perfect square being the square of 6.

Other perfect squares that are between 0 and 1000 are 1, 4, 9, 16, 25, 3649, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324... 961.

Since 961 is the square of 31, it shows that there are 31 perfect squares  greater than 0 but less than 1000.

Answer:

a) y=8

b) x= 9

Step-by-step explanation:

a)

y/16= 2/4

y= 16 * 1/2      (cross multiply)

y= 8

b) x/5 = 36/20

x= 5 * 36/20    (cross multiply)

x= 9

What's 17= z- (-9) days
Arte-miy333 [17]
Z - (-9) is the same as z + 9. Subtracting a negative is the same as adding.

Therefore 
17 = z - (-9)
is the same as
17 = z + 9

To get 'z' all by itself, we need to subtract 9 from both sides. We subtract 9 from both sides to undo the "plus 9" occurring to the 'z' on the right side.

17 = z + 9
17-9 = z + 9=9 ... subtracting 9 from both sides
8 = z
z = 8

So the answer is z = 8

---------------------------

Check:

17 = z - (-9)
17 = 8 - (-9) ... replace z with 8
17 = 8 + 9
17 = 17

1. Find the volume for 5 different spheres by randomly choosing different radii.
Sophie [7]

The volume of the sphere is given by :

V=\frac{4}{3}\pi r^{3}

And volume of cylinder is given as :

V=\pi r^{2}h

So, as given to select the radius randomly and the height of the cylinder will be the diameter of the sphere.

The radius are = 3, 5, 8, 10, 12

And height will be = 6, 10, 16, 20, 24

1. Volume of sphere with radius 3 = \frac{4}{3}*3.14*3*3*3= 113.04 units

Volume of cylinder with radius 3 and height 6 = 3.14*3*3*6=169.56 units

2. volume of sphere with radius 5 = 523.60 units

volume of cylinder with height 10 = 785.40 units

3. volume of sphere with radius 8 = 2144.66 units

volume of cylinder with height 16 = 3216.99 units

4. volume of sphere with radius 10 = 4188.79 units

volume of cylinder with height 20 = 6283.19 units

5. volume of sphere with radius 12 = 7238.23 units

volume of cylinder with height 24 = 10857.34 units
