a kittens heartbeat can be as fast as 240 beats per minute . to find the number of times a kittens heart beats in 30 seconds , A

Alina [70]

I do not agree. If you divide 240 by 30, it would be 8 heartbeats, which is absurd. It's impossible for something to survive with 8 heartbeats per 30 seconds.
In order to get the CORRECT answer, divide 240 by 60 seconds.
This would give you 4 heartbeats per second.
Then, multiply it by 30 seconds, which would give you 120 heartbeats.

CORRECT answer: 120

Write the following expression with as few symbols as possible, using the notational conventions:

My name is Ann [436]

Answer:

The simplified expressions are (<em>x</em> + <em>y·</em>z' + <em>t</em>) and <em>x·</em>(<em>x</em> + <em>y</em>' + <em>z</em>) respectively.

Step-by-step explanation:

The expressions provided are:

$(i)\ x+((y\times (z')) +t)\\\\(ii)\ x\times((x+(y'))+z)$

(i)

Simplify the first expression with as few symbols as possible:

$x+((y\times (z')) +t)=x+(yz'+t)$

$=x+yz'+t$

(ii)

Simplify the second expression with as few symbols as possible:

$x\times((x+(y'))+z)=x\times ((x+y')+z)$

$=x (x+y'+z)$

Thus, the simplified expressions are (<em>x</em> + <em>y·</em>z' + <em>t</em>) and <em>x·</em>(<em>x</em> + <em>y</em>' + <em>z</em>) respectively.
