a pizza shop delivered 8 pepperoni pizzas to a college on the first night of final exams. the total cost of the pizzas was $56. a small pizza costs $3 and contains 4 ounces of pepperoni. a medium pizza costs $5 and contains 9 ounces of pepperoni. a large pizza cost $11 and contains 12 ounces of pepperoni. the owner of the pizza shop used 4 pounds 12 ounces of pepperoni in making the pizzas. how many pizzas of each size were delivered to the college?

Answers

From the word problem given, the number of pizzas each that were delivered are:

1 small7 medium; and2 large.
What is the calculation justifying the above solution?

Step I

Let a = number of small pizzas delivered

Let b = number of medium pizzas delivered

Let c = number of large pizzas delivered

Step 2 - Creating relevant expressions based on number and type ordered, we have:

a + b + c = 8.............................1

3a + 5b + 11c = 56..................2
4a + 9b + 12C = 4 * 8 + 12.....3a

We can rewrite (3) as
4a + 9b + 12C = 44 ....3b

Step 3

Multiply both sides of (1) by 4

We have

4a +4b +4c = 32

If we remove (1) from (3) we have

4a + 9b + 12C = 44

-
4a +4b +4c = 32
5b +8C = 12......................(4)

Multiply both sides of (1) by 3 and subtract from (2), and we have:

3a + 3b + 3c = 24, removing this from (2) we have

3a + 5b + 11c = 56

-
3a + 3b + 3c = 24
2b + 8c = 32.....................(5)

Step 4 - Subtract (4) from (5)

2b + 8c = 32
-
5b + 8c = 12
-3b = 20

b = - 20/3

= - 6.67
Since we cannot have negative values, we work with absolute value to get:

b [tex]\approx[/tex] 7

Since b = 7

2(7) + 8c = 32
8c = 32 - 14
c = 18/8

c [tex]\approx[/tex] 2


Plug in that back into a we have

a + b + c = 8
a + 7 + 2 = 8

a = 8-9
a = -1 (recall we must have absolute values)
a therefore = 1.

Hence the number of pizzas that were ordered are:

1 small
7 medium; and

2 large.

what is the line that passes through the point -1, four and is parallel to the line 2
X plus Y equals one

Answers

The line that passes through the point -1, four and is parallel to the line 2 X plus Y equals one is y + 2x = 2.

What is a slope?

Slope is measure of steepness of a line.

The Equation of line is y = mx + c

where,

m is slope

c is y intercept

To find equation of the parallel line we must first find the slope of the original line

The original line is 2x + y = 1

We must first write equation in the general form above

That's

y = - 2x + 1

Comparing with general equation above

Slope = - 2

Since lines are parallel their slope are also same

Slope of parallel line = - 2

So the equation of line using point

( - 1 , 4) and the slope - 2 is

y-4= -2(x+1)

y-4= 2x-2

y+2x= -2+4

We have final answer as

y + 2x = 2

Multiplicative inverses or ______, is a number that when multiplied by the ___________ gives the product as 1.

Answers

Answer: Multiplicative inverses or reciprocal, is a number that when multiplied by the given number gives the product as 1.

Step-by-step explanation:

In 1787 the French scientist Jacques Charles observed that when he plotted the graph of volume of a fixed amount of air versus the temperature of the air, the points lay along a straight line. Therefore, he concluded that volume of a gas varies linearly with temperature. Suppose that at 27º C a certain amount of air occupies a volume of 500 cm3. When it is warmed to 90º C, it occupies 605 cm3.
a) Write the particular equation in slope-intercept form expressing volume in terms of temperature.
b) Predict the volume at 60º C.
c) The process of predicting a value between two data points is called “interpolation”.
What is the origin of the word?
d) Predict the volume at 300º C.
e) The process of predicting a value beyond any given data points is called
“extrapolation”. What is the origin of this word?
f) Extrapolate your mathematical model back to the point where the volume is zero.
That is, find the temperature-intercept.
g) What is the special name given to the temperature in part f)?

Answers

The relationship between the volume, V, and temperature, T, of a given mass of gas, found by the French scientist Jacques Charles, gives;

a) The slope–intercept form of the equation that expresses the volume in terms of the temperature of the gas is; [tex] \displaystyle{ V = 1. \bar 6 \cdot T + 455}[/tex]

b) The volume at 60 °C is 555 cm³

c) Interpolation originates from the verb interpolare

d) The temperature at 300 °Cis 955 cm³

e) Extrapolation originates from 'extra' (meaning outside) and the shortened form of Interpolation

f) The temperature–intercept is -273 °C

g) The special name is the absolute zero temperature

What is Charles law for gases?

Charles law states that the volume of a given mass of gas is directly proportional to its temperature given in Kelvin.

Mathematically, Charles Law states that; V = K•T

Where;

V = The volume of the gas

T = The gas temperature

K = The proportionality constant

The volume occupied by the gas at 27 °C = 500 cm³

The volume occupied at 90 °C = 605 cm³

a) To write the equation in slope–intercept form, we have;

[tex] \displaystyle{ Slope = \frac{605 - 500}{90 - 27} =1. \bar{6} =1. \bar{6}}[/tex]

The equation of the line in point and slope form is therefore;

Point–slope form; [tex] \displaystyle{ V - 500 = 1. \bar{6} \times (T - 27) }[/tex]

[tex] \displaystyle{ V = 1. \bar{6} \cdot T -45 + 500 = 1. \bar{6} \cdot T + 455}[/tex]

The equation in slope–intercept form of expressing the volume, V, in terms of the temperature, T, is therefore;

Volume equation; [tex] \displaystyle{ V = 1. \bar{6} \cdot T + 455}[/tex]

b) The volume at 60 °C is given from the equation that gives the volume, V, in terms of time, T as follows;

[tex] \displaystyle{ V(T) = 1. \bar{6} \cdot T + 455}[/tex]

When T = 60 °C

[tex] \displaystyle{ V(60) = 1. \bar{6} \times 60 + 455=555}[/tex]

The volume occupied by the gas at 60 °C is 555 cm³

c) The word interpolate originated from the Latin word interpolare which means to alter or refurbish

d) The volume occupied by the gas at 300 °C is given by the function for the volume, V, in terms of temperature, T, equation as follows;

When T = 300 °C

[tex] \displaystyle{ V(300) = 1. \bar{6} \times 300 + 455 = 955}[/tex]

The volume of the gas at 300 °C is 955 cm³

e) Extrapolation originate from the word 'extra' which refers to the outside of an area. Extra is combined with a short form of interpolate to give the word, extrapolation

f) When the volume is zero, the volume function equation can be used to find the temperature as follows;

Volume function; [tex] \displaystyle{ V = 1. \bar{6} \cdot T + 455}[/tex]

When V = 0

[tex] \displaystyle{ V = 0 =1. \bar{6} \cdot T + 455}[/tex]

[tex] \displaystyle{ -455 = 1. \bar{6} \cdot T }[/tex]

[tex] \displaystyle{T = \frac{3 \times (-455)}{5}= -273 }[/tex]

The temperature at which the volume of the gas is zero is -273 °C

g) The special name given to -273 °C of the gas is the absolute zero temperature.

There are more than 12 pens in the box.
Simon is going to take at random two pens from the box.

The probability that Simon will take two pens of the same colour is
27/55
Work out the number of green pens in the box.

Answers

Answer:

Green Pens : 21

Step-by-step explanation:

Let the number of
green pens = x

Three more blue pens than green pens translates to
=> number of blue pens = number of green pens + 3
=> blue pens  = x + 3

Total number of pens = blues + green = x + 3 + x = 2x + 3

Probability of taking 2 green pens:
The first time a green pen is taken out, the probability
P( 1s green pen) = Number of green pens/Total number of pens

= [tex]\dfrac{x}{2x + 3}[/tex]

After the first green pen is removed, the number of green pens will be one less and so will the total number of pens

Number of green pens = x - 1
Total number of pens = 2x + 3 - 1 = 2x + 2

P(second green pen | first green pen)

[tex]=\dfrac{x-1}{2x + 2}[/tex]

P(2 green pens) = P(first green pen) x P(second green pen)
[tex]= \dfrac{x}{2x + 3} \times \dfrac{x-1}{2x + 2}\\\\=\dfrac{x(x -1)}{(2x +3)(2x+2)}[/tex]          [1]

Probability of 2 blue pens

P( 1st blue pen) = number of blue pens/total number of pens
[tex]=\dfrac{x + 3}{2x + 3}[/tex]

P(second blue pen = (number of pens remaining if first was blue) ÷ total number of pens - 1

If the first pen taken was blue then there will be 2x + 3 - 1 blue pens out of a total of 2x + 3 - 1 pens

P(2nd blue pen | first blue pen)

[tex]=\dfrac{x + 2}{2x + 2}[/tex]

[tex]\text{P(2 blue pens)} =\dfrac{x + 3}{2x + 3} \times \dfrac{x + 2}{2x + 2}[/tex][tex]=\dfrac{(x + 3)(x+2)}{(2x + 3)({2x + 2})}[/tex]  [2]

The probability of either 2 green pens or 2 blue pens is the sum of the two probability expressions [1] and [2]

[tex]= \dfrac{x(x -1)}{(2x +3)(2x+2)} + \dfrac{(x + 3)(x+2)}{(2x + 3)({2x + 2})}[/tex]

[tex]= \dfrac{x(x - 1)+ (x + 3) (x +2)}{(2x + 3)(2x + 2)}\\\\\\= \dfrac{2x^2+4x+6}{(2x + 3)(2x + 2)}\\\\\\\\[/tex]

Numerator: factor out 2 to get 2(x² + 2x + 3)

denominator = 4x²+10x+6 = 2 (2x² + 5x + 3)

2 of numerator and 2 of denominator cancel out to give the final expression:

[tex]\dfrac{x^2\:+\:2x\:+\:3}{2x^2+\:5x\:+\:3}[/tex]

But we are given that the probability of picking 2 pens of the same color = 27/55

This will give us:
[tex]\dfrac{x^2\:+\:2x\:+\:3}{2x^2+\:5x\:+\:3} = \dfrac{27}{55}[/tex]

Cross-multiplying we get

[tex]55\left(x^2+\:2x\:+\:3\right)=27\left(2x^2+\:5x\:+\:3\right)[/tex]

=> [tex]55x^2+110x+165 = 54x^2+135x+81[/tex]

Grouping like terms and simplifying gives
[tex]x^2-25x+84=0[/tex]

This is a quadratic equation which can be solved using a scientific calculator (as I did)

The solution set is

x = 21, x = 4

Remember x = number of green pens. We can ignore x = 4 because the total number of pens given by the expression 2x + 3 will be less than 12 and we are told there are more than 12 pens total

So the solution is x = 21 (number of green pens)
Number of blue pens = x + 3 = 21 + 3 = 24

Answer: Green Pens : 21   and Blue Pens: 24

The value of a negative number such that the sum of that number and its square is 42 is -7.

What are negative numbers?A negative number is one that always has a value lower than zero and is denoted by the minus (-) symbol. On a number line, negative numbers are displayed to the left of zero. Negative numbers include -6 and -15 as examples.

Let the negative number be -x.

According to the question, the sum of the negative number and its square is 42.

So, we form an equation

- x + (-x)² = 42

x² - x - 42 = 0

Solving the quadratic equation,

x² - 7x + 6x - 42 = 0

x(x - 7) + 6(x - 7) = 0

(x - 7)(x + 6) = 0

x = -6 and x = 7

We have taken the number -x to be negative.

What is a factor?

In Mathematics, factors are positive integers that can divide a number evenly.  Suppose we multiply two numbers to get product. The number that is multiplied are the factors of the product. Each number is factor of itself.  Factors have many real-life examples, such as arranging sweets in box, arranging numbers in pattern, distributing chocolates among children, etc. To find the factors of number, we need to use the multiplication or division method.

Factors are numbers that can divide a number exactly.  Hence, after the division, there is no remainder left. Factors are numbers you multiply together to get the another number. Thus, factor is the divisor of another number.

f(x)=[tex]x^{4}-px^{3}+7qx+1[/tex]

To solve the question  [tex]\frac{3.1 * 10}{2.0 * 10^{2}}[/tex].

Canceling out 10 from the denominator and numerator

= [tex]\frac{3.1 }{2.0 * 10}[/tex]

= 3.1 / 20

Remove the decimal point from the numerator and add one zero in the denominator

= 31/ 200

As we divide the numbers using the long division method we get the decimal number as a result,

= 0.155

a family decides to have children until it has three chil- dren of the same gender. assuming p(b) 5 p(g) 5 .5, what is the pmf of x 5 the number of children in the family?

Answers

one is the pmf or probability mass function of X = number of children in the family

The Probability Mass Function (PMF) is also called a probability function or frequency function which characterizes the distribution of a discrete random variable.

X takes values: { 3, 4, 5 }

where:  P ( X = 3 ) + P ( X = 4 ) + P ( X = 5 ) = 1

For X = 3 we have : BBB or GGG.

P ( X = 3 ) = ( 1/2 * 1/2 * 1/2 ) * 2 = 1/8 * 2 = 2 / 8 = 1/4

P ( X = 4 ) = ( 1/2 * 1/2 * 1/2 * 1/2 ) * 6 = 6 /16 = 3/8

P ( X = 5 ) = ( 1/2 * 1/2 * 1/2 * 1/2 * 1/2 ) * 12 = 12 / 32 = 3/8

1 / 4 + 3 / 8 + 3 / 8 = 8 / 8 = 1

The first term of the arithmetic progression is 5

What is an arithmetic sequence?

An arithmetic sequence can simply be defined as a sequence of numbers or terms in which the differences between successive or consecutive terms are always equal.

The formula for the nth term of an arithmetic sequence is expressed as;

Tn = a + (n-1)d

Where;

Tn is the nth term of the sequencea is the first term of the sequencen is the number of termsd is the common difference between successive terms

Given that the first term of the sequence is a, the 43rd term is 26 and the common difference is 1/2

Substitute the values into the formula

26 = a + (43 -1)1/2

expand the bracket

26 = a + (42)1/2

Multiply through

26 = a + 21

collect like terms

a = 26 - 21

a = 5

Thus, the value is 5

this dude has a farm and 1/8 were pigs, 2/3 were horses, and the rest were chickens. there are 10 chickens, how many animals are on the farm?

Answers

The number of animals that are on the farm is 48.

How many animals are on the farm?

A fraction is a non-integer that is made up of a numerator and a denominator. An example of a fraction is 2/3.

The first step is to determine the fraction of the animals that are chickens.

Fraction that are chickens = 1 -  fraction that are pigs and horses.

[tex]\frac{1}{8} + \frac{2}{3}[/tex]

[tex]\frac{3 + 16}{24}[/tex] = [tex]\frac{19}{24}[/tex]

Fraction that are chickens = 1 - 19/24 = 5/24

The next step is to divide the number of chickens by the fraction of the chickens.

Number of animals = number of chickens ÷ fraction of chickens

10 ÷ 5/24

10 x 24/ 5 = 48
