Step-by-step explanation:

Radius (r) = 5.8 cm

circumference (c)

= 2πr

= 2 * 3.14 * 5.8

= 36.424

= 36.42 CM

Hope it will help :)

How many ways are there to select a 5-card hand from a regular deck such that the hand contains at least one card from each suit
Snezhnost [94]

Answer:

There are 685464 ways of selecting the 5-card hand

Step-by-step explanation:

Since the hand has 5 cards and there should be at least 1 card for each suit, then there should be 3 suits that appear once in the hand, and one suit that apperas twice.

In order to create a possible hand, first we select the suit that will appear twice. There are 4 possibilities for this. For that suit, we select the 2 cards that appear with the respective suit. Since there are 13 cards for each suit, then we have {13 \choose 2} = 78 possibilities. Then we pick one card of all remaining 3 suits. We have 13 ways to pick a card in each case.

This gives us a total of 4*78*13³ = 685464 possibilities to select the hand.

1.  You need to make a proportion

2. Your proportion would be 8 over 10 equals X over 15

3. Your equation would be 10x=15(8)

4. 15x8=125

5. 10x=125

6. you would divide 125 by 10

7. thats your answer

PLEASE HHELP!!! Bring the fraction:
Anna35 [415]

Answer:

\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}

\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}

Step-by-step explanation:

Given

\frac{b}{7a^2c}

Express the denominator as 35a^3c^3

To do this, we divide35a^3c^3 by the denominator

\frac{35a^3c^3}{7a^2c} = 5ac^2

So, the required fraction is:

\frac{b}{7a^2c} * \frac{5ac^2}{5ac^2}

\frac{5abc^2}{35a^3c^3}

Hence:

\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}

Given

\frac{a}{a - 4}

Express the denominator as 16 - a^2

Multiply the fraction a+4/a+4

So, we have:

\frac{a}{a - 4} * \frac{(a + 4)}{(a + 4)}

Apply difference of two squares to the denominator

\frac{a^2 + 4a}{a^2 - 16}

Take the additive inverse of the numerator and denominator

\frac{-(a^2 + 4a)}{-(a^2 - 16)}

\frac{-a^2 - 4a}{16 -a^2}

Hence:

\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}
