Find the product of 21 and (6.3 • 10-4).

Answers

Answer 1

Answer:

Answer:

1,239

Step-by-step explanation:

This problem can be rewritten as 21 • (6.3 • 10 - 4)

Following the order of operations (PEMDAS) we first have to solve what's in the parentheses.

The next letter is M for multiplication so we have to do 6.3 times 10 which makes 63. That makes 63 - 4 which is 59.

Lastly, since we finished the parentheses, we then do 21 • 59, which solves to be 1,239.

In 1 hour how many more times does a rabbits heart beat than a dogs rabbits heart beat per 1 minute 212 dogs heart beat per 1 minute

Answers

Answer: In 1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat

Step-by-step explanation:

Since we have given that

Rabbit's heart beat in 1 min 212 times more than dog's heart beat in 1 min.

So, in 1 hour , we get,

$1\text{ hour }= 60\text{ minutes}\nso, heartbeat = 212* 60=12720$

So, in 1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat .

Beverly can drive 600 miles in the same time as it takes Susan to drive 500 miles. If Beverly drives 10 mph faster than Susan, then how fast does Beverly drive?

Answers

t = D/rtimes the sameBev = Susan's time600mi/r+10 = 500mi/r
600r = 500r + 5000100r = 5000r = 50mph, Susan's speed. Beverly's is 60 mph 50+10And...checking600/60 = 500/50 = 10hr

600/x +10 =500/x Cross multiply.
600x=5000+500x
100x=5000
X=50
50+10=60
Check work. Beverly drives 60mph

What is 1/10 of 90000

Answers

The $$\n((1)/(10)) ^(th)$ of 90000 is 9000.

We have a number - 90000

We have to determine $$\n((1)/(10)) ^(th)$ part of this number.

Evaluate 1/5 of 100.

The $$\n((1)/(5)) ^(th)$ part of 100 will be -

$(1)/(5) * 100$ = 20

According to the question, we have -

Number - 90000

Therefore, 1/10 of 90000 will be -

$(1)/(10) * 90000$ = 9000

Hence, $$\n((1)/(10)) ^(th)$ of 90000 is 9000.
