Suppose your heart beats 70 times a minute. Combine the time it will take for it to beat 1 million times.

Answers

Answer:

For example, if your heart beats 72 times per minute, 70 beats per minute would give a reasonable estimate. Next find how many days it takes for 1 million heartbeats: 1,000,000 ÷ 100,000 = 10. Thus, 1,000,000 beats take 10 days.

Step-by-step explanation:

Answer:

14285.7142857

Step-by-step explanation:

1,000,000 divided by 70 equals 14285.7142857

Find the measures of two supplementary angles if their measures are in the given ratio.
3:7

Answers

Two supplementary angles are in the ratio 3:7. Find the angles ?

Let the two angles be 3x and 7x.

Supplementary angles add up to 180 degrees.

Therefore:

3x + 7x = 180

10x = 180

x = 18

3x = 3 * 18 = 54

7x = 7 * 18 = 126

Measure of angles are 54° and 126°.

What is Supplementary angle?

Sum of two or more angles are 180 degrees then, the angles are called supplementary angle.

Given that;

The ratio of angles are 3 : 7.

Now,

Let the two angles be 3x and 7x.

Since, Supplementary angles are add up to 180 degrees.

So,

3x + 7x = 180

10x = 180

x = 18

So, First angle of supplemental angles = 3x

                                                           = 3 × 18  

                                                           = 54

And, Second angle of supplemental angles = 7x

                                                                   = 7 × 18

                                                                   = 126

Thus, Measure of angles are 54° and 126°.

here are some numbers 2 9 14 36 40 what number is a multiple of 12 which number is a prime number which number is a factor of 64

Answers

Answer:  36 is a multiple of 12

2 is a prime number.

2 is a factor of 64

Step-by-step explanation:

12 × 3 =36, so 12 is one of the factors.

2 is the only even prime number. All other even numbers are multiples of 2.

9 is not a prime number. 3 × 3 = 9

2 is a factor of 64.  2 × 32 = 64  None of the other numbers given can divide evenly into 64, so they are not factors of 64.

grapes are sold for $3.20 per bag. if you have $12, how many bags of grapes can you buy?

Answers

Answer:

you can buy 4 bags of grapes with $12.

Step-by-step explanation:

Hope this helps :)

Answer:

Step-by-step explanation:

Since we know that one bag of grapes = $3.20, we can divide $12 by $3.20 to get how many bags of grapes you can buy.

12/3.2=3.75.

In the exact amount, you can buy 3.75 bags of grapes. Now you can't buy .75 of a bag. Rounding it, you would have approximiatly bought 4 bags. Reality, you would have bought 3 bags.
