The most appropriate choice for fraction will be given by

Fraction of banana bread will be donated to the homeless is [tex]\frac{1}{4}[/tex]

What is a fraction?

Suppose there is a collection of objects and some part of the objects are taken from the collection. The part which has been taken is called fraction. In other words, part of a whole is called fraction.

The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.

Here,

Total number of banana breads 16

Number of adults who got banana bread = 6

Number of Children who got banana bread = 6

Total number of children and adult who got banana bread = 6 + 6 = 12

Number of banana breads given to the homeless = 16 - 12 = 4

Fraction of banana bread given to the homeless = [tex]\frac{4}{16}[/tex]

                                                                                 = [tex]\frac{1}{4}[/tex]

The expression can be rewritten as:

2*(n - 3)

This is twice an integer number, so this is an even number

Here we know that n is an integer larger than 1, and we have the expression:

n² - (n - 2)² - 2

Now, remember that for any integer m, 2m is always an even number.

Expanding the term in the middle of the expression we get:

n² - (n - 2)² - 2

n² - (n² - 4n + 4) - 2

4n - 4 - 2 = 4n - 6 = 2*(n - 3)

Integer numbers are closed under addition, then n - 3 is an integer, so we have:

Notice that

Then, the answer is c=25.

The total surface area of the pyramid (a) is  624.32 cm² , and of pyramid (b) is 265.6 m²  .

The Total Surface Area of the Pyramid with pentagon base can be calculated using the formula

TSA = 5/2*b(a+s) ,

where b is the base length (side of pentagon)

s is the slant height ,

a is the apothem

and the Total Surface Area of the Pyramid with square base can be calculated using the formula .

TSA = b² + 2bs

where , b is the base and

s is the slant height .

Pyramid (a)

we can see from the figure that ,the pyramid has a pentagon base ,

So, the TSA will be 5/2*b(a+s) ,

in the figure , given that height =12 cm , apothem = 7.8cm

we find the slant height by Pythagoras theorem

(slant height)²=(height)²+(apothem)²

(slant height)² = 12² + 7.8²

(slant height) = √(12² + 7.8²)

(slant height) = √(144+60.84)

(slant height) = 14.3 cm

Substituting in TSA formula , TSA = 5/2*b(a+s)

we get ,

TSA = 5/2*11.3(7.8+14.3)

= 2.5*11.3(22.1)

= 28.25*22.1

=624.32 cm²

Pyramid (b)

we can see from the figure that ,the pyramid has a square base ,

So, the TSA will be b² + 2bs,

in the figure , given that height =12 m , apothem = 4 m

we find the slant height by Pythagoras theorem

(slant height)²=(height)²+(apothem)²

(slant height)² = 12² + 4²

(slant height) = √(12² + 4²)

(slant height) = √(144+16)

(slant height) = 12.6 m

Substituting in TSA formula , TSA = b² + 2bs

we get ,

TSA = 8² + 2*8*12.6

= 64 + 16*12.6

= 64 + 201.6

= 265.6 m²

Therefore , the total surface area of the pyramid (a) is 624.32 cm²  , and of pyramid (b) is 265.6 m² .

By using a translation rule, the coordinates of C' are (- 1, - 2). (Correct choice: E)

Triangles are defined by the locations of its three vertices on Cartesian plane and we must find the locations of the images of the three vertices after applying a translation rule. In this case, we must translate each vertex  2 units upward and 4 units to the right. The general translation formula is described below:

P'(x, y) = P(x, y) + T(x, y)

Where:

If we know that C(x, y) = (- 5, - 4) and T(x, y) = (4, 2), then the location of the image of point C is:

The exponential function which shows the exponential growth rate of graduating women is: A(t) = A₀e∧(0.037t).

The following equation can be used to calculate an exponential function again for number of women graduating from four-year colleges in t years after 1930:

A(t) = A₀e∧(rt)

In which A₀ is the starting point and r is the exponential growth rate expressed as a decimal.

In 1930, 48780 women received a bachelor's degree.

This implies that;

A₀ = 48780

In 2004, approximately 756000  people

The year 2003 is 73 years after 1930, that also means

Using the equation as an example:

A(t) = A₀e∧(rt)

Put the values;

756000 = 48780 e∧(73r)

e∧(73r) = 756000/ 48780

e∧(73r) = 15.49

Taking log both side;

73r = ㏑ 15.49

r = 2.7/7

r = 0.037

The function becomes;

A(t) = A₀e∧(0.037t)

a)The expression for the total cost for all four classes can be given as 32s + 200. b) the rational expression for the cost per student is 2(4s+25)/s c) if each class has 20 students then the cost per student is equal to $10.50.

a) Total cost expression can be determined as follows:

total fees of admission + fees of bus = total cost

total cost = (4s × 8) + 200

total cost = 32s + 200

b) A rational expression to determine the cost per student can be calculated as follows:

cost per student = total cost ÷ the total number of students

cost per student = 32s + 200 ÷ 4s

We now factor the numerator by using its GCF;

cost per student = 4 × 2 (4s + 25) / 4×s

cost per student =2 (4s + 25) / s

c) Now using this expression we can find the cost per student if each class has 20 students;

cost per student = 2 (4s + 25) / s

cost per student = 2 ( 4×20 + 25)/ 20

cost per student = 2 ( 80 + 25) / 20

cost per student = 2 (105) / 20

cost per student = 210 / 20 = $10.50

The triangle is Isosceles and Acute.

From the given data, the coordinates of the three points of the triangle are, A(2, 3), B(8, 3), and C(5, 6).

applying the distance formula, D = √((x2-x1)²+(y2-y1)²) the distance AC and BC are obtained as 3√2 and the distance AB as 2√3.

From this, it can be concluded that AC=BC≠AB.

thus since two of the sides, AC and BC are equal and the third side AB is not equal to AC and BC hence the given triangle is an isosceles triangle.

To check whether the given triangle is right, acute.

A right triangle is a triangle with one of its angles equal to 90 degrees.

An acute triangle is a triangle with all three of its angles less than 90 degrees.

An obtuse triangle is a triangle with at least one of its angles greater than 90 degrees.

To check whether the given triangle is right, acute, or obtuse we use the law of cosines.

To find the angle of a triangle given 3 of its sides, let the angle between the sides AB and AC be A then,

cos(A) =  (AC² + AB² − BC²)÷(2×AB×AC).

cos(A) = (3√2² + 2√3² - 3√2²)÷(2×2√3×3√2) =2÷√6

[tex]cos^{-1}[/tex](2÷√6) = 39.182.

Let the angle between the sides AB and BC be B then,

cos(B) =  (BC² + AB² − AC²)÷(2×AB×BC).

cos(B) = (3√2² + 2√3² - 3√2²)÷(2×2√3×3√2) =2÷√6

[tex]cos^{-1}[/tex](2÷√6) = 39.182.

Let the angle between the sides AC and BC be then,

cos(C) =  (AC² + BC² − AB²)÷(2×AC×BC).

cos(C) = (3√2² + 3√2² - 2√3²)÷(2×3√2×3√2) =2÷3

[tex]cos^{-1}[/tex](2÷3) = 53.544.

Since all the angles A, B, and C is less than 90 degrees the triangle is acute.
