If six chocolate bars cost £3. 80 how much is for 5

Answers

Answer:

5 chocolate bars cost 3.15 (i don't have that currency symbol on my keyboard)

Step-by-step explanation:

First, let's find out what one costs, so it'll be easier.

3.80/6=0.63

Multiply the amount for one chocolate bar by five:

0.63*5=3.15

And there you go! 5 bars cost 3.15

I hope this helped!

Answer:

 £4.56

Step-by-step explanation:

5 chocolate bars= £3.80

1 chocolate bar= £3.80 / 5 = £0.76

Therefore, 6 chocolate bars= £0.76 x 6 =  £4.56

A rectangle has sides measuring (6x 4) units and (2x 11) units. Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points) Part B: What are the degree and classification of the expression obtained in Part A? (3 points) Part C: How does Part A demonstrate the closure property for polynomials? (3 points).

Answers

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,

What is the area of a rectangle?

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]

(q+4)(9q+5)=0 solve for q

Answers

Answer:

q = -4
q = -5/9

Step-by-step explanation:

Hi!

To solve this question, we can use the zero product property.

What is the Zero-Product property?

The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.

We have (q+4)(9q +5) = 0

That means either q + 4 = 0, or 9q + 5 = 0.

Solve:

q + 4 = 0q = -4

9q + 5 = 09q = -5q = -5/9

We can check both cases:

(-4 + 4)(-36 + 5) = 0

0(-31) = 0

0 = 0

(-9/5 + 4)(9(-5/9) + 5) = 0

(2.2)(-5 + 5) = 0

(2.2)0 = 0

0 = 0

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;

1 hour has 60 minutes24 Hours in a day365 days in a year

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.

Kabita has two bags. In the first bag there are 5 blue discs and 3 red discs. In the second bag there are 7 blue discs and 4 red discs. Kabita takes at random a disc from the first bag. She then takes at random a disc from the second bag


Work out the probability that kABITA takes 2 red discs

Answers

The probability that Kabita would take 2 red discs from the bags is 3/22.

What is probability?

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

The probability that Kabita would take 2 red discs = (number of red discs in bag 1 / total number of discs in bag 1) x  (number of red discs in bag 2 / total number of discs in bag 2)

(3/8) x (4/11) = 3/22
