Lets say you have 5x5. you would just add 5+5+5+5+5. To get a whole number for a fraction you have to do this. lets say you have 8/8 that would be equal to 8 circles and eight of those circles would be shaded in. 8/8 is one whole also 7/1 is a whole. It all depends on the problem you are trying to figure out

Multiplication is the same as repeated addition so let us take an example for a better understanding

2/3 * 4

Looks more like this

2/3 + 2/3 +2/3 = 2/3 = 8 /3

(If you add them up, we will get the same answer if we multiply it)

Same as 2/3 *4/1 = 8/3

On the other hand if you have whole numbers that you need to solve like 3*4 this means that 3 is added 4 times

3 + 3+ 3+ 3 = 12

Which would be the same thing as

3*4 = 12

Answer:

a = -2

Step-by-step explanation:

-3a + 8 = 14

14 - 8

= 6

-3a = 6

6/-3

= -2

a = -2

The base of a solid is the region in the first quadrant between the graph of y=x2 and the x -axis for 0≤x≤1 . For the solid, eac

Answer:

The volume of the solid is π/40 cubic units.

Step-by-step explanation:

Please refer to the graph below.

Recall that the area of a semi-circle is given by:

$\displaystyle A=\frac{1}{2}\pi r^2$

The volume of the solid will be the integral from x = 0 to x = 1 of area A. Since the diameter is given by y, then the radius is y/2. Hence, the volume of the solid is:

$\displaystyle V=\int_0^1\frac{1}{2}\pi \left(\frac{y}{2}\right)^2\, dx$
