1) if the cost of one case of fresh pineapples is $14.95 for a case of 6, and the
calculated waste factor is 15 percent, what is the actual cost of each pineapple?

Answers

Answer 1

Using proportions, it is found that the actual cost of each pineapple is of $2.12

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, considering that the waste factor is of 15%, the total price should be of:

P = 0.85 x $14.95 = $12.7075.

For a case of 6 pineapples, hence the price of each is given by:

Pp = $12.7075/6 = $2.12.

Answer 2

The actual cost of each pineapple with a waste factor of 15% is $12.71

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

The cost of one case of fresh pineapples is $14.95 and the calculated waste factor is 15 percent. Hence:

Actual cost = 14.95 - 15% of 14.95 = $12.71

The actual cost of each pineapple with a waste factor of 15% is $12.71

The equation [tex]y = x^2 - 8x + 3[/tex] is an illustration of a quadratic equation

The vertex of the quadratic equation [tex]y = x^2 - 8x + 3[/tex] is (4,-13)

How to determine the vertex?

The equation is given as:-

[tex]y = x^2 - 8x + 3[/tex]

A quadratic equation is represented as:

[tex]y = ax^2 + bx + c[/tex]

By comparison, we have:

a = 1; b = -8; c = 3

The x-coordinate of the vertex is:
[tex]x = -\frac b{2a}[/tex]

So, we have:

[tex]x = \frac 8{2*1}[/tex]

[tex]x = 4[/tex]

Substitute 4 for y in [tex]y = x^2 - 8x + 3[/tex]

[tex]y = 4^2 - 8 * 4 + 3[/tex]

[tex]y = -13[/tex]

When x = 2 and 3, we have:

[tex]y = 2^2 - 8 * 2 + 3 = -9[/tex]

[tex]y = 3^2 - 8 * 3 + 3 = -12[/tex]

When x = 5 and 6, we have:

[tex]y = 5^2 - 8 * 5 + 3 = -12[/tex]

[tex]y = 6^2 - 8 * 6 + 3 = -9[/tex]

So, the table of values is:

x       y

2      -9

3      -12

4      -13

5      -12

6      -9

What are the zeros of the function y=6x^2-11x+3

Answers

To algebraically find the zeroes of this function, we must factor by grouping

y = ax^2 -bx +c
y = 6x^2 - 11x + 3

Multiply a and c.

6 x 3 = 18

Identify b, b= -11

We need to think of 2 numbers that when added, will give us the b value -(11) and when multiplied, will give us (ac) 18.

-9 + -2 = -11

-9 • -2 = 18

Now, we rewrite the equation using these 2 numbers.

y = 6x^2 - 9x - 2x + 3

Now, we put brackets around the first 2 and last 2 terms.

y = (6x^2 - 9x) (-2x + 3)

Now, simplify the two sets of brackets individually. You will find that the things left inside the brackets will be the exact same.

y = -3x(2x + 3) -1(2x + 3)

Attach the 2 coefficients together and rewrite.

y = (-3x - 1)(2x + 3)

Since we are solving for zeroes, make y = 0

0 = (-3x - 1) (2x + 3)

Both of these binomials equal 0, we must evaluate them separately.

0 = -3x - 1

3x = -1

x = -1/3

Second one:

0 = 2x + 3

-3 = 2x

x = -3/2

zeroes: (-1/3) , (-3/2)

if necessary, round your answer to the nearest whole number.

Answers

Answer: 1,393 meters tall

Step-by-step explanation:

Plug in 1710 meters for the initial amount, 0.05 for the rate of decrease, and 4 millennia for the time elapsed.

y

= a(1–r)t

y

= 1,710(1–0.05)4 Plug in values

y

= 1,710(0.95)4 Subtract

y

= 1,710(0.81450…) Simplify

y

= 1,392.80568… Multiply

Round to the nearest whole number.

1,392.80568… → 1,393

To the nearest whole number, the mountain will be 1,393 meters tall.

What is the difference between a factor of a number and a multiple of a number? use the number 25 has an example

Answers

Answer:

factor: a submultiple; an integer value that gives an integer quotient when the number is divided by it.multiple: the product of the number and another integer

Step-by-step explanation:

Factors

A set of factors of a number (N) is a set of integers {f1, f2, f3, ...} whose product is the number:

  f1 × f2 × f3 × ... = N

Often the term "factors" is used to mean "prime factors," the set of prime numbers whose product is N.

When N = 25, the prime factors are {5, 5}. That is ...

  5×5 = 25

__

Divisors

A "divisor" of a number is a sub-multiple of N. That is, the quotient N/k is an integer for some divisor k of N. Usually, we're interested in integer divisors. All prime factors will be integer divisors of N. The term "factor" is often used when the term "divisor" is meant.

Divisors of N = 25 include 1, 5, and 25. There will be an odd number of integer divisors (as here) if the number N is a perfect square.

__

Multiples

For an integer k, the value k×N is called a multiple of N, often, the k-th multiple of N.

Multiples of 25 include 25, 50, 75, 100, 125, and any other decimal number ending in 25, 50, 75, or 00.

__

Another example

When N=30, the prime factors are {2, 3, 5}. The divisors are {1, 2, 3, 5, 6, 10, 15, 30}. (Note there are an even number of divisors.) Multiples of 30 include 30, 60, 90, 120, ....

find the circumference of circle with radius rcm​

Answers

Step-by-step explanation:

By definition, pi is equal to c/d, where c is the circumference and d is the diameter.

This means that C = pi(d).

However, since diameter is twice the radius, if we let the radius be r cm, d=2r.

This gives that C=2pi(r).

Factoring a polynomial is expressing the polynomial as a product of two or more factors.

We can factor out a 2.

Now, we can write down the 2 and factor the [tex](x^2 - x - 20)[/tex].

[tex](x^2-x - 20)=x^2-5x+4x-20\\ =x(x-5)+4(x-5)\\ =(x+4)(x-5)[/tex]

[tex]f(x)=2x^2 -2x -40=2(x^2 - x - 20)=2(x+4)(x-5)[/tex]
