Mathematics
1 answer:
Nana76 [90]3 years ago
5 0

Step-by-step explanation:

as with any division of a multiplication of various factors, we can always simplify by reducing the factors in the top and the bottom of the same base.

in the same way we can for example do

36×2⁶×3⁴×5² / 4×2⁵×3³×5²

and deal with every exponent base individually creating

9×2¹×3¹×5⁰ = 9×2×3

we can do with variable based exponents.

24a⁸b⁸c⁶ / 8a⁷b³c³ =

= 3a¹b⁵c³

you know, when we divide, we simply subtract exponents.

8-7, 8-3, 6-3

and the constants are simply divided 24/8 = 3

A cylinder has a radius of 5 feet and a height of 8 feet. Which of the following can be used to calculate the volume of a cone t
Lilit [14]
The answer is 1 over 3(3.14)(5²)(8) 

The volume of the cylinder (V1) is:
V1 = π · r² · h                (r - radius, h - height)

The volume of the cone (V2) is:
V2 = 1/3 π · r² · h         (r - radius, h - height)

It is given:
r = 5 feet
h = 8 feet
π = 3.14

Therefore, the volume of the cone is:
V2 = 1/3 · 3.14 · 5² · 8   which is the same as 1 over 3(3.14)(5²)(8).

The mean score on a set of 17 test is 72. Suppose two more students take the test and score 68 and 63. What is the new mean?
Masja [62]

Answer:

New mean=71.32

Step-by-step explanation:

The expression for the total initial score is;

T=M×S

where;

T=total initial score

M=mean score

S=number in the set

replacing;

T=unknown

M=72

S=17

replacing;

T=72×17=1,224

The total initial score=1,224

Determine the total score by;

total score=total initial score+total final score

where;

total initial score=1,224

total final score=(68+63)=131

replacing;

total score=1,224+131=1,355

Determine the new mean;

New mean=total score/new number

where;

total score=1,355

new number=(17+2)=19

replacing;

new mean=1,355/19=71.32
