What is 1/4+3/8+1/2+5/8+7/8

Mathematics
1 answer:
Vadim26 [7]3 years ago
6 0

Answer:

2⅝

Step-by-step explanation:

You must convert each fraction to a <em>common denominator</em>.

The <em>least common multiple</em> of 2, 4, and 8 is 8.

  1/4  +3/8  + 1/2  + 5/8 + 7/8     Convert to a common denominator

= 2/8 + 3/8 + 4/8 + 5/8 + 7/8

= (2   + 3     + 4    + 5     + 7)/8

= 21/8                                        Convert to a mixed number

= (16 + 5)/8

=  2  +  ⅝

= 2⅝

Zielflug [23.3K]

Convert the 6 seconds to hours:

5 seconds x x 1/60 ( minutes per seconds) x 1/60 (Hours per minute) = 6/3600 = 1/600 hours.

Distance = speed x time

Distance = 585 x 1/600 = 585/600 = 0.975 miles

Convert miles to feet:

0.975 x 5280 = 5,148 feet

The plane traveled 5,148 feet in 6 seconds.

Given the following: P(A) =0.3 P(B) = 0.2 P(A OR B) = 0.5 P(A AND B) = 0 Which of the following is true?a. A and B are disjoint.
erastova [34]

Answer:

a. A and B are disjoint

Step-by-step explanation:

We know that P(A and B)=0, It means that event A and event B have nothing in common and it means that event A and event B are disjoints events.

The event A and event B are independent if

P( A and B)= P(A)*P(B)

P(A)*P(B)=0.3*0.2=0.06

So, P(A and B)≠P(A)*P(B)

Hence events A and B are not independent.

Option a is A and B are disjoints which is correct

Option b is A and B are neither disjoints nor independent which is partially false as A and B are disjoints event.

Option c states that A and B are independent which is clearly false.

Option d states that A and B are disjoints and independent which is partially false as A and B are not independent.

Hence the correct option is option A.

What is the solution to the equation?<br><br>√2x+10−6=2<br><br><br>*Picture of the Problem Below*
Klio2033 [76]

Answer:

x = 27

Step-by-step explanation:

Given

\sqrt{2x+10} - 6 = 2 ( add 6 to both sides )

\sqrt{2x+10} = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27
