What whole number is equivalent to 8/2

svetoff [14.1K]

4 is the whole number equivalent. When dealing with an improper fraction or one that is "top heavy" you take the denominater (the bottom number) unto the numerator.
Two(2)goes into 8, 4 times, making it whole!

viva [34]

Answer:

4 [miles].

Step-by-step explanation:

1) the condition 'the entire trip took 5 hours' can be written as (where t_us - time spent upstream, t_ds - time spent downstream)

$t_{us}+t_{ds}=5;$

2) but the distance [D] upstream is equal the distance downstream, then the condition above can be written:

$\frac{D}{V_{us}} +\frac{D}{V_{ds}} =5; \ (V_{us}-rowing \ upstream,V_{ds}-rowing \ downstream);$

3) finally,

$D=\frac{5V_{us}*V_{ds}}{V_{us}+V_{ds}};$

D=5*4/5=4 [miles].

A = {a, b, c, d}

Helen [10]

Answer:

Johnny is wrong.

$A \cup B = \left\{a,b,c,d,e,f,g,h\right\}$

Step-by-step explanation:

Johnny is wrong.

A better definition would be: $A \cup B$ is the set of all elements that belong to at least one A or B.

So, the elements that belong to both A and B, like c and d in this exercise, also belong to $A \cup B$ .

So:

$A \cup B=\left\{a,b,c,d,e,f,g,h\right\}$

Need help with this plz

Answer:

$x = \frac{ - 24 \pm \sqrt{ - 288} }{4} \\ = \frac{ - 24 \pm \sqrt{ ( - 1) {(12)}^{2} (2)} }{4} \\ = \frac{ - 24 \pm \sqrt{ - 1} \sqrt{ {12}^{2} } \sqrt{2} }{4} \\ = \frac{ - 24 \pm i 12\sqrt{2} }{4} \\ =-\frac{24}{4}\pm \frac{i12\sqrt{2}}{4}\\= - 6 \pm \: i3 \sqrt{2}$
