Answer:
Step-by-step explanation:
6. 78-2(3+16) /4
(78-2x19)/4
( 78 -38)/4
40/4=10
7.
(66/11)3 -6*8
6x6x6 -48
216-48=168
8.
10/7+2(8-11/2)
10/7+2(8-5.5)
10/7+2*2.5
10/7+5
10/7 + 35/7
45/7 =
[ ( |500,000-700,000| ) / 500,000 ] * 100 = 40%

Answer:
32 cm³
Step-by-step explanation:
Volume of a sphere is:

Volume of a cylinder is:

The volume of the cylinder is 48 cm³.
The cylinder has the same radius (r) and height (2r) as the sphere.

Therefore, the volume of the sphere is:

Step-by-step explanation:
Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

Addition and subtraction requires that we find a common demoninator.
For example,

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

Then we add the numerators

Then we should reduce.

Division is a little trickier because we have to flip-flop the second term and then multiply. For example:
