Solve the equation. x² =96 A 4/6 B 16/6 C 9 D 9,-9

alexgriva [62]

Answer:

x = ± 4 $\sqrt{6}$

Step-by-step explanation:

Given

x² = 96 ( take the square root of both sides )

x = ± $\sqrt{96}$ = ± $\sqrt{16(6)}$ = $\sqrt{16}$ × $\sqrt{6}$ = ± 4 $\sqrt{6}$

How would I solve this? Because I don't understand it at all.

Mandarinka [93]

Answer:

v= s/t = sqrt(360^2+480^2) x 0.3048/0.5 = 365.76(m/s)

Step-by-step explanation:

s =sqrt(360^2+480^2)

s-ft-to-m = s*0.3048

t = 0.5

A car travels about 34 feet in one second. At this speed,

natta225 [31]

Answer:

Step-by-step explanation:

34 * 7= 238

34 feet per second, means that we have to mulitply 7 by 34.

Its really simple!

1 second: 34

7 seconds: ?

for example, if we needed 2 seconds we would muliplty by 2, 34 * 2 because we double it, the same way we would solve that, we would solve 34*7

A survey of 64 informed voters in Kenya revealed the following information:

Elena L [17]

Answer:

i) 12 believe neither of these things.

ii) 3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.

Step-by-step explanation:

I'm going to solve these question treating these events as Venn sets.

I am going to say that:

Event A: Voting is a waste of time.

Event B: They have been abducated by space aliens.

45 believe that Voting is a waste of time

This means that $A = 45$

49 believe that they have been abducted by space aliens

This means that $B = 49$

42 believe both of these things

This means that $A \cap B = 42$

i). How many believe neither of these things?

Total of 64.

At least one is:

$A \cup B = A + B - A \cap B$

With the values we have

$A \cup B = 45 + 49 - 42 = 52$

None:

$64 - 52 = 12$

12 believe neither of these things.

ii). How many believe Voting is a waste of time but don't believe that they have been abducted by space aliens?

This is:

$A - B = A - (A \cap B) = 45 - 42 = 3$

3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.
