As a town gets​ smaller, the population of its high school decreases by 5​% each year. The senior class has 320 students now. In how many years will it have about 100 ​students? Write an equation. Then solve the equation without graphing.

Answers

Answer 1

The number of years until the town will have 100 students is given as follows:

22.68 years.

How to model the situation?

A decaying exponential function is modeled as follows:

y = a(1 - r)^x.

In which:

a is the initial value.r is the decay rate.

The parameter values for this problem are given as follows:

a = 320, r = 0.05.

Hence the function is given as follows:

y = 320(0.95)^x.

The time it will take for the population to have 100 students is x when y = 100, hence:

100 = 320(0.95)^x

(0.95)^x = 100/320

(0.95)^x = 0.3125

x log(0.95) = log(0.3125)

x = log(0.3125)/log(0.95)

x = 22.68 years.

Describe the symmetries of a rhombus and prove that the set of symmetries forms a group. Give Cayley tables for both the symmetries of a rectangle and the symmetries of a rhombus. Are the symmetries of a rectangle and those of a rhombus the same?

Answers

The symmetries of a rectangle and those of a rhombus are not the same, as the rectangle has two additional symmetries.

A rhombus is a quadrilateral with all sides of equivalent length, and it has the accompanying symmetries:

Identity symmetry: The rhombus stays unaltered when reflected about its center.

Rotational symmetry: The rhombus stays unaltered when pivoted 180 degrees about its center.

Reflective symmetry: The rhombus stays unaltered when reflected about its two diagonals.

These symmetries structure a gathering under the operation of the organization of symmetries. A gathering is a bunch of components with a twofold operation (for this situation, the creation of symmetries) that fulfills the cooperative, identity and converse properties.

The arrangement of symmetries of a rhombus fulfills these properties, making it a group.

The Cayley table for the symmetries of a rhombus is as per the following:

E R1 R2 R3

R1 E R3 R2

R2 R3 E R1

R3 R2 R1 E

Where E addresses the identity symmetry, R1 addresses the 180-degree turn symmetry, R2 addresses the symmetry around one diagonal, and R3 addresses the symmetry about the other diagonal.

Then again, the symmetries of a rectangle are:

Identity symmetry: The rectangle stays unaltered when reflected about its center.

Rotational symmetry: The rectangle stays unaltered when pivoted 180 degrees about its center.

Reflective symmetry: The rectangle stays unaltered when reflected about its two vertical and two horizontal axis.

The Cayley table for the symmetries of a rectangle is as per the following:

E R1 R2 R3 R4

R1 E R3 R2 R4

R2 R3 E R1 R4

R3 R2 R1 E R4

R4 R4 R4 R4 E

Where E addresses the identity symmetry, R1 addresses the 180-degree turn symmetry, R2 addresses the symmetry around one vertical axis, R3 addresses the symmetry around one horizontal axis and R4 addresses the symmetry about the two diagonals.

We can see that the arrangement of symmetries of a rectangle and those of a rhombus are not something similar.

The rectangle has two additional symmetries, the symmetry around one vertical and one horizontal axis, which are not present in the rhombus.

Answer:

Case 1 : x = - 2, y = 3

Case 2 : x = 5. y = 2

Step-by-step explanation:

Case 1

y - x = 5  ---------> Eq 2

Add both Eq 1 and y,

5y + x = 13

 y  - x =  5

________

6y + 0 = 18

6y = 18

y = 18/6

y = 3

Substitute y = 3 in Eq 2,

3 - x = 5

3 - 5 = x

- 2 = x

x = - 2

Hence,

x = - 2

y = 3

Case 2

2x + y = 12 ---------> Eq 1

6x + 5y = 40 -----------> Eq 2

Multiply Eq 1 with 3,

6x + 3y = 36 --------> Eq 3

Eq 2 - Eq 3,

 6x + 5y = 40

2y = 4

y = 4/2

y = 2

Substitute y = 2 in equation 1,

2x = 12 - 2

2x = 10

x = 10/2

x = 5

Explain the features of term rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form. The rectangle's longer side is its length, while its shorter side is its breadth.

A walkway around a rectangular garden.

The garden's size is 4(4.5 x + 1.5) square meters.The garden's and the walkway's combined area is 5.5(8 x + 4).

The equation of the line parallel to the line is y = -4x + 10

The equation of the line perpendicular to the line is y = 1/4x +3/2

Using the point (1, 6) and (2, 2) on the line to get the slop:

Slope = 2-6/2-1

Slope = -4/1

Slope = -4

The equation is written in point slope form as y-y0 = m(x-x0)

Substitute a point and the given slope for the equation parallel to the line

y - 2 = -4(x-2)

y - 2 = -4x + 8

y+4x = 10

Hence the equation of the line parallel to the line is y = -4x + 10

The needed slope for the perpendicular line is 1/4.

Substitute a point and the given slope for the equation parallel to the line

y - 2 = 1/4(x-2)

4(y - 2) = x - 2

4y - 8 =x -2

models the growth of HCG for Brad's mother's pregnancy.

Answers

The required function is 200 (1.4)ˣ = 5, where the value of x is calculated to be -11.

The given function is y = a bˣ

x₁ = 0, y₁ = 200

x₂ = 2,  y₂ = 392

Let us determine a, b.

a b⁰ = 200

a b² = 392

a = 200

200 b² = 392

b² = 392/200 = 49/25 = 7/5 = 1.4

So, the function is y = 200 (1.4)ˣ

Now, let us determine x for y = 5,

200 (1.4)ˣ = 5

(1.4)ˣ = 0.25

Taking log on both sides,

log (1.4)ˣ = log 0.025

x log 1.4 = log 0.025

x = log 0.025/log 1.4

x ≈ -11

amy uses 41-cent stamps and 6-cent stamps to mail a gift card to a friend. if the postage is $1.77, how many of each stamp did amy use?

Answers

If Amy uses 41-cent stamps and 6-cent stamps to mail a gift card to a friend worth of $1.77 , then the number of 41 cent stamp used is 3  and the number of 6 cent stamps used is  9 .

Let the number of 41 cents stamps used in postage is = x ;

let the number of 6 cents stamps used in postage is = y ;

the amount 41 cents in dollars is = $0.41  ;

and amount 6 cents in dollars is = $0.06  ;

Amy used 41-cent stamps , 6-cent stamps to pay $1.77 in postage

it is represented in equation form as  ⇒ 0.41x + 0.06y = 1.77

Multiplying on both sides by 100 , we get

⇒ 41x + 6y = 177  ;

⇒ y = (177 - 41x)/6 ;

We will test for corresponding values of x and y to satisfies this equation and the number of stamps must be whole numbers.

If x = 1 , then y = 26.66

If x = 2 , then y = 15.83

If x = 3 , then y = 9

If x = 4 , then y = 2.16 .

395 gallons will contain 1,495.075 L of water.

A gallon is a unit of liquid measure equal to eight pints. It is approximately 4.546 litres in the United Kingdom.

It is about 3.785 litres in the United States.

To convert litres to gallons, for example, a quart is somewhat less than a litre and 4 litres is slightly more than 1 gallon. 1 litre equals 0.264 gallon (a little more than a quart), and 4 litres equals 1.06 gallon.

One US gallon is approximately 3.79 litres;

one imperial gallon is approximately 4.55 litres.

The dry gallon in the United States is roughly 4.41 litres. As a result, one gallon, regardless of kind, is always larger than one litre.

One gallon contains 3.785 L of water,

Hence 395 gallons will contain 3.785395 3.785×395 Liters of water,

Answers

The ratio of false positives to true positives is 8 over 54.

According to the Question

Results of a strep throat test performed on a sample of 400 ill people are displayed in the table's data. People who have the flu and those who don't are separated into two categories. The patients are then separated into groups based on whether they tested positive or negative for strep throat within each of these categories.

We must first define what a true positive and a false positive are in order to calculate the ratio of false positives to true positives. A patient who tests positive for strep throat but does not actually have the illness is said to have a false positive. The 8% of patients in this instance who tested positive for strep throat but did not have the flu would fall under that category. A patient who tests positive for strep throat and truly has the illness is said to have a true positive. That would be the 54% of patients who tested positive for both the flu and strep throat in this instance.

We divide the percentage of false positives (8%) by the percentage of true positives (54%), which gives us the ratio of false positives to true positives.

As a result, the ratio becomes 8% / 54%, or 8/54.

It's critical to remember that this ratio is dependent on the sample and test performed and may not be the same for different populations or testing methodologies.

Claim -

“If he planted an equal number in each row there were 3 remaining.”

Reasoning -

If the gardener needed to plant 75 shrubs in 4 equal rows then there would be 18 shrubs in each row, 72 shrubs would be planted. That would be that 3 shrubs are remaining.
The answer will be 3 left over.

Explanation: If the gardener has 75 shrubs and wants to plant them evenly in each row, you have to do division and see if there is any remainders.


75 divided by 4 is 18 with only 3 remaining.

So 18 is the shrubs planted evenly and 3 is the one remaining.

The height of the trapezoid is 5 cm

Answers

The area of trapezoid is 47.5 cm².

What is trapezoid?

A quadrilateral having only two sides parallel.The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).

Thus, if we have:

Length of its parallel sides = 'a' and 'b' units respectively

Perpendicular distance between its parallel sides = 'h' units,

Then, we get:

[tex]A = \dfrac{1}{2}\times(a+b) \times h \: \rm unit^2[/tex]

Given;

trapezoid has two bases that measure 11 cm and 8 cm.

a= 11 cm, b= 8 cm

Now, height= 5

A = (½* height) x (Sum of the bases)

A= 1/2 * ( 11 + 8) * 5

A= 95/2

Therefore, the Area trapezoid will be 47.5 cm²
