Elizabeth and Herman are collecting aluminum cana for a frundraiser at their school. Elizabeth was able to collect 50 cans each day from Monday to Friday, Herman was able to collect double that amount each day except Friday, when he collected none. Each can is worth 2 cents. What are the quantities in this situation?

Answers

The total cans collected by both Elizabeth and Herman is 650 and the total amount of money realized is 1300 cents.

What is rate?

A rate is a ratio in which the two terms being compared have different unit's.For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces.

The aluminum cans collected by Elizabeth from Monday to Fridays is 50× 5days = 250 cans

Herman collected double from Monday to Thursday and collected non on Friday, therefore the total cans collected by Herman = 50×2× 4 days= 400cans

the total cans collected = 250+ 400 cans = 650cans

therefore the total money realized since 1 can is with 2 cent is 650× 2= 1300cents

Given CB || ED,;CB=ED prove CBF= EDF using isometric ridged transformation outline the necessary transformation to prove CBF = EDF using a paragraph proof. Be sure to name specific sides or angles used in the transformation and any congruency statements

Answers

The given triangle is rotated about 180 degrees and as such, we can say that the triangle CBF is congruent to the triangle EDF.

How to prove congruent angles?

From the attached image, we see that CB is parallel to ED. We also see that the transversal lines are  BD and CE.

The point E will become the image of point C by a rotation of 180° around the point F.

Now, the point D will be the image of point B by a rotation of 180° around the point F.

Rotation is a type of transformation and as such  ΔEDF will be the image of  ΔCBF.

Therefore we can conclude that ΔCBF ≅ ΔEDF

The second way to prove this congruency is as follows;

∠B = ∠D  (Due to the fact that alternate angles are congruent)

∠C = ∠E  (Due to the fact that alternate angles are congruent)

Now, since CB ≅ ED , then it means that ΔCBF ≅ ΔEDF by SAS congruency postulate

Give your answer correct to three significant figures.

Answers

The percentage increase in Hayley's fuel bills from 2021 to 2022 is equal to 17.105%.

What is a Percentage Increase?

The phrase "percentage increase" (or "percentage change" in general) refers to the difference between the final and starting values of a quantity, expressed as a percentage of that number's original value.

Steps to Calculate Percentage Increase?

The formula to calculate Increase (I) is given by, [tex]I=Y-X[/tex], where [tex]X[/tex] is the original value and [tex]Y[/tex] is the new value.The percentage increase formula is given by, [tex]\%I=\frac{I}{X} \times 100[/tex]

Here, in the question, it is given that,

The original amount (X) or the fuel bill in 2021 is £76.

The new amount (Y) or the fuel bill in 2022 is £89.

So, the Increase (I) in the fuel bills from 2021 and 2022 is calculated as,

[tex]I=Y-X\\\implies I=89-76\\\implies I=13[/tex]

Now, we can calculate the percentage increase in fuel bills from 2021 to 2022 as,

[tex]\%I=\frac{I}{X} \times 100\\\implies \%I=\frac{13}{76} \times 100\\\implies \%I=17.105\%[/tex]

Therefore, the percentage increase in Hayley's fuel bills from 2021 to 2022 is 17.105%.

one serving of a certain brand of yogurt contains 7g of fat. the low fat version contains 45.75% less fat per serving. how many grams of fat does one serving of the low fat yogurt contain?

Answers

The grams of fat that are contained in one serving of the low-fat yogurt are: 3.7968g.

How do we obtain the grams of fat for one serving of low-fat yogurt?

To obtain the number of grams of fat that is contained in one serving of the low-fat yogurt, we need to first note the percentage content of the low-fat version of yogurt.

100 - 45.75% = 54.25% or 0.5425

Since one serving of the yogurt contains 7g of fat, then the low-fat serving will be equal to:

7g × 0.5425  = 3.7968

The quadratic equation in standard form that contains the roots 5 + 4√10 and 5 - 4√10 is y = x² - 10 · x - 135.

How to determine quadratic formula in standard form

In this question we must derive a quadratic equation in standard form, that is, a polynomial of the form:

y = a · x² + b · x + c

Where b / a = - r₁ - r₂ and c / a = r₁ · r₂ and r₁ and r₂ are the roots of the polynomial. If we know that a = 1, r₁ = 5 + 4√10 and r₂ = 5 - 4√10, then the quadratic equation is:

y = a · [x² + (b / a) · x + (c / a)]

y = x² + (- 5 - 4√10 - 5 + 4√10) · x + (5 + 4√10) · (5 - 4√10)

Seven of the angles of a decagon have measures whose sum is 1220. Of the remaining 3 angles, exactly two are complementary and exactly two are supplementary. Find the measures of these three angles.

Answers

The measures of the remaining three angles of the decagon are 40, 50 and 130 degrees.

How to find angles of a decagon?

A decagon simony means a polygon with 10 sides. In a regular decagon, the interior angles add up to 1440 degrees, and the exterior angles add up to 360 degrees.

Complementary angles sum up to 90 degrees while supplementary angles sum up to 180 degrees.

Therefore,

1440 - 1220 = 220

Let the angles be a, b and c.

Therefore,

a + b + c  =220

a + b = 90

b + c = 180

Hence,

a = 220 - 180

a = 40°

b = 90 - 40

b = 50°

c = 180 - 50

c = 130°

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given the functions as;

f(x)=4x-2

g(x)=5-x^2

We need to find (f o g)(-2)

So, first, we will find the function (f o g)(x) as follows:

[tex]\begin{gathered} \mleft(f\circ g\mright)(x)=f\lbrack g(x)\rbrack=4(5-x^2)-2 \\ (f\circ g)(x)=20-4x^2-2 \\ (f\circ g)(x)=18-4x^2 \end{gathered}[/tex]

Now, substitute with x = -2 then we get;

[tex](f\circ g)(-2)=18-4\cdot(-2)^2=18-4\cdot4=18-16=2[/tex]

Thus, the answer to the part is (a) (f o g)(-2) = 2

b) (g o f)(-2)

We need to find (g o f)(x) as follows:

[tex](g\circ f)(x)=g\lbrack f(x)\rbrack=5-(4x-2)^2[/tex]

Now Substitute with x = -2, then we get;

A telephone exchange operator assumes that 8% of the phone calls are wrong numbers.

If the operator is correct, what is the probability that the proportion of wrong numbers in a sample of 494 phone calls would differ from the population proportion by more than 3%? Round your answer to four decimal places.

Answers

The probability that the phone calls would differ from the population proportion by more than 3% is 0

How to determine the probability value?

From the question, the given parameters about the distribution are

Proportion, p = 8%Sample size, n = 494The actual proportion, x = greater than 3%

The mean is calculated as

Mean = np

So, we have

Mean = 8% * 494 = 39.52

The standard deviation is calculated as

Standard deviation = √np(1 - p)

So, we have

Standard deviation = √494 * 8% (1 - 8%) = 0.77

The z-score is calculated using the following formula

[tex]z = \frac{\bar p - p}{\sqrt{p(1 - p)}/n}[/tex]

Substitute the given parameters in the above equation

[tex]z = \frac{8\% - 3\%}{\sqrt{8\% * (1 - 8\%)}/494}[/tex]

Evaluate

z = 90.9

The probability is then calculated as:

P(x > 3%) = P(z > 90.9)

From the z table of probabilities, we have;

P(x > 3%) = 0

Hence, the probability is 0

This is the required exponential function.

Since x represents time here, then x has to be positive

Domain of the function is all positive real number

Now

As  [tex]x\rightarrow \infty[/tex], [tex]f(x) \rightarrow \infty[/tex]

As  [tex]x\rightarrow -\infty[/tex], [tex]f(x) \rightarrow 0[/tex]

Range is [tex](0, \infty)[/tex]

For y- intercept, x = 0

Putting x = 0, we get y = 3

y- intercept is 3

This means initial value of the coin is $3

The graph of the function has been attached here
