Answer:

1.715km

Step-by-step explanation:

If it travels 343m/s, and we know there are 1000m in a km therefore it travels 0.343km in one second.

0.343km x 5s= 1.715km in 5 seconds.

Answer:

To find the speed of sound you must use this equation: v= (331.5 +0.6 x T) m/s.

Step-by-step explanation:

You have to convert 68 F to Celsius which is 20 degrees. Then write down the equation and the knowns and unknowns.

So the equation is this

v= (331.5 + 0.6 x 20) m/s

The answer is: 0.3435 km/s times 5 = 1.7175 (5km)

Make sure to show all these steps. I believe it is correct.

Given the original statement "If a number is negative, the additive inverse is positive,” which are true? Select three options.
Sergeu [11.5K]

Answer:

The three options are;

1) If p = a number is negative and q = the additive inverse is positive, the original statement is p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement the inverse of the original statement is ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q

Step-by-step explanation:

Given a statement if p then q, we have, p → q. The converse of the original statement is then, if q, then p while the inverse of the original statement is then if not p then not q, and the contrapositive statement is then if not q then not p

Mathematically, we have;

The given conditional statement;

If a number is negative, the additive inverse is positive which can be expressed as follows;

The conditional statement is p → q

The converse statement is q → p

The inverse statement is ~p → ~q

The contrapositive statement is ~q → ~p

Therefore, we have;

1) The conditional statement, if p = a number is negative and q = the additive inverse is positive, the original statement which is a conditional statement is therefore p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement, which is a conditional statement is p → q, the inverse of the original conditional statement is therefore, ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the original statement, which is a conditional statement is therefore, q → p, the contrapositive of the original conditional statement  is therefore ~p → ~q.

- 5g = 20<br> How do you solve this
dezoksy [38]

Answer:

g= -4

Step-by-step explanation:

-5g = 20

<u>Divide the -5 to both sides</u>

-5g / -5 = 20/ -5

<u>both -5 cancel out and g is left alone</u>

<u>20/-5 = -4</u>

<u>g= -4</u>
