ANSWER THIS QUICK!! IT¨S WORTH 46 POINTS

Mathematics
1 answer:
Tamiku [17]3 years ago
3 0

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

<h3>\frac{4\pi \sqrt{5} - 2\pi \sqrt{5}  }{3 \sqrt{5} }</h3>

<u>Simplify the numerator first</u>

Since they have the same square root that's root 5 we can subtract them directly

That's

<h3>4\pi \sqrt{5}  - 2\pi \sqrt{5}  = (4\pi - 2\pi) \sqrt{5}  \\  = 2\pi \sqrt{5}</h3>

So we have

<h3>\frac{2\pi \sqrt{5} }{ 3\sqrt{5} }</h3>

<u>Reduce the expression with √5</u>

We have the final answer as

<h2>\frac{2\pi}{3}</h2>

Hope this helps you

If the geometric mean of a and 28 is 16 sqrt 7 find a
kozerog [31]

Answer:

a = 64

Step-by-step explanation:

The geometric mean of 2 numbers a and b is \sqrt{ab} , then

\sqrt{28a} = 16\sqrt{7} ( square both sides )

28a = (16\sqrt{7} )² = 1792 ( divide both sides by 28 )

a = 64

A die is rolled 20 times. given that three of the rolls came up 1, five came up 2, four came up 3, two came up 4, three came up
Serjik [45]

Solution:

Number of times a die is rolled = 20

1 - 3=A

2 - 5=B

3 - 4=C

4 - 2=D

5 - 3=E

6 -  3=F

Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times

            = Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes

= 6! × [ 3! × 5! × 4!×2!×3!×3!]

= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]

= 895795200  Ways
