Answer:

volume of cuboid = 2h(l+b)

Step-by-step explanation:

since you are asking the method on how to do this I will just help you out with basic idea.

first,

convert mixed fractions into fractions before writing them in given.

eg:

GIiven,

width(b)= (7×2+1)/2 = 15/2= 7.5 in

then you can find out the length by doubling the width since the question has said the length is twice the width.

after that we can find out the height by subtracting (2×2+1)/2 = 5/2= 2.5 in from the length.

finally figure out the volume by using formula for volume of cuboid i.e 2h(l+b)

Answer:

The average heart beat in a lifetime is 2,365,200,00 beats.

Step-by-step explanation:

Given;

An average human heart beats 60 times per minute.

If an average person lives to the age of 75.

Knowing that;

Question to Answer;

How many times does the average heart beat in a lifetime.

Base to the question,

An average human heart beats 60 times per minute.

And there is 60 beats in a minute and 60 minutes in an hour,

Thus,

Heart beat per hour = 60 beats × 60 minutes = 3,600 beats per hour.

Thus,

The amount of beats in an hour by the number of hours in a day.

Heart beats per day = 3600 × 24 hours = 86,400 beats per day

Thus,

The number of days in a year is 365 in a year, but use the flat rate of 365 since that is generally the accepted answer.

Heart beat per year = 86,400 × 365 days = 31,536,000 beats per year

For this reason,

An average person lives to the age of 75,

Heart beat in a lifetime to age of 75 years,

= 31,536,000 × 75 years = 2,365,200,00 beats in a lifetime.

Hence, The average heart beat in a lifetime is 2,365,200,00 beats.

Answer:

Step-by-step explanation:

What's the line plot about, so we can find an appropriate label for it?  

The area of the rectangle is [tex]12x^{2} + 74x + 44[/tex]

The degree of the polynomial is 2nd degree and the classification of the polynomial is trinomial

The closure property of the polynomial is demonstrated as follows:

[tex](6x + 4) (2x + 11) = (2x + 11 )(6x + 4)[/tex]

The sides of the rectangle are (6x + 4) and (2x + 11). Therefore,

The area of the rectangle is,

[tex]area = lw[/tex]

where,l = length,w = width.

Therefore, by using formula,

[tex]area = (6x + 4)(2x + 11)[/tex]

[tex]area = 12x^{2} + 66x + 8x + 44[/tex]

[tex]area = 12x^{2} + 74x + 44[/tex]

b).The degree of the polynomial is 2nd degree and the classification of the polynomial is trinomial(it has three terms)

c).When something is closed, the output will be the same type of object as the inputs. Therefore, to demonstrate the closure property:

[tex](6x + 4) (2x + 11) = (2x + 11 )(6x + 4)[/tex]

answer:

A. ( -1, 6), (0, 3), (1, 0), (2, -3)

explanation:

The x values fit the y values.

(a)

y = -3x + 3

y = -3(-1) + 3

y = 3 + 3

y = 6

(b)

y = -3x + 3

y = -3(0) + 3

y = 3

(c)

y = -3x + 3

y = -3(1) + 3

y = 0

(d)

y = -3x + 3

y = -3(2) + 3

y = -3

Answer:

Step-by-step explanation:

S x T = D

S = 45 km/h

T = 3.41 hours

D = 45 km/1 h x 3.41

D = 153.45/3.41

D = 45 km *
