Answer:

Length = 20 inches

Area = 300 inches

Step-by-step explanation:

<em><u>TO FIND THE LENGTH</u></em>

Pythagorean Theorem: 15 squared + x squared = 25 squared

                                    = 225 + x squared = 625

                                     - 225                      - 225

                                    = x squared = 400

                                find square root

                                    = x = 20 inches

                                               x = 20 inches

                                                        Length = 20 inches

<u><em>TO FIND THE AREA</em></u>

length x width

length = 20 inches

width = 15 inches

20 x 15 = 300

             Area = 300 inches

What is the conditional probability that exactly four heads appear when a fair coin is flipped five times
cestrela7 [59]

Answer:

5/32

Step-by-step explanation:

If a coin if flipped five times with four heads, then it has exactly one tail. The number of way to arrange four heads and one tail are as follows:

T H H H H

H T H H H

H H T H H

H H H T H

H H H H T

Essentially, there are five way because there are five "positions" where the tail could be.

Then, you need to find the total amount of possibilities for flipping a coin five times. Every time you flip it, there are two possibilities- heads and tails. Therefore, for five flips, the total amount of possibilities is

2x2x2x2x2 = 32

You know that

probability= # of desired outcome

                   ----------------------------------  

                      # of total outcomes

So the probablity is 5/32.

If 2 over 5 tons of concrete covers 5 over 6 of a wall, how many tons of concrete are required to cover the entire wall?
Dominik [7]

Answer:

A. 12.25 tons

Step-by-step explanation:

We will let x represent the amount required to cover the entire wall.

We can divided 2/5 by 5/6 to solve for x

2/5 divided by 5/6=x

When you divide by a fraction, you can always multiply by the reciprocal (flipped number).

Our new equation is:

2/5·6/5=12/25
