Heart beats 2,320 times during 20 minutes of rowing. While resting the heart is beating 16 times in 15 seconds. What is the diff

Mrac [35]

Answer: 0.87 times per second (Or 52.2 times per minute)

Step-by-step explanation:

You need to make the conversion from minutes to seconds.

Remember that 1 minute has 60 seconds. Then 20 minutes to seconds is:

$(20minutes)(\frac{60seconds}{1minute})=1,200seconds$

Find the number of times the heart beats in 1 second when it is rowing:

$x_1=\frac{(2,320times)}{1,200seconds}=1.93\ times\ per\ second$

Find the number of times the heart beats in 1 second when it is resting:

$x_2=\frac{(16times)}{15seconds}=1.06\ times\ per\ second$

Then the difference is:

$difference=(1.93-1.06)\ times\ per\ second\\difference=0.87\ times\ per\ second$

(Or 52.2 times per minute)

A) Simplify the expression and explain each step. (2 points) 4(3x+2) -2 = ?

TiliK225 [7]

Answer:

6 (2 x + 1)

Step-by-step explanation:

Simplify the following:

4 (3 x + 2) - 2

Hint: | Distribute 4 over 3 x + 2.

4 (3 x + 2) = 12 x + 8:

12 x + 8 - 2

Hint: | Group like terms in 8 + 12 x - 2.

Grouping like terms, 8 + 12 x - 2 = 12 x + (8 - 2):

12 x + (8 - 2)

Hint: | Subtract 2 from 8.

8 - 2 = 6:

12 x + 6

Hint: | Factor out the greatest common divisor of the coefficients of 12 x + 6.

Factor 6 out of 12 x + 6:

Answer: 6 (2 x + 1)

Brianna answers 5 questions for each chapter of a book she reads in English class.

Pani-rosa [81]

Answer:

q=5c

Step-by-step explanation:

q is the total number of questions, so the other numbers/variables must be multiplied together to equal q.

c is the number of chapters read, so that must be multiplied by 5 (questions per chapter) in order to equal q.
