The perimeters of the two composite figures are listed below:

Case C: 50.913π mm

Case D: 20.310 cm

In this problem we find two composite figures, whose perimeter have to be found. Perimeter is the length of all borders of the figure. The first figure is formed two semicircles and the second figure is formed by two semicircles and two right triangles, whose perimeter formulas are:

Semicircle

s = π · r

Triangle

s = b + h + p

Where:

Case c - The perimeter of the shape is:

s = π · (28 mm) + π · (14 mm) + 28 mm

s = 50.913π mm

Case d - The perimeter of the shape is:

s = 2π · (1.8 cm) + 2 · (4.5 cm)

s = 20.310 cm

The inequality can be written as g * 37.5 >= 120.

What is linear inequality?

A linear inequality is a mathematical statement that describes a relationship between two or more variables that form a half-plane when graphed. The equation of a linear inequality is in the form of "ax + by < c" or "ax + by > c" or "ax + by <= c" or "ax + by >= c", where x and y are variables, and a, b and c are constants.

An inequality that could be used to determine the minimum number of gallons, g, of gasoline Darla would need to drive 120 miles to her brother's house is:

g >= 120/37.5

This inequality states that the number of gallons, g, must be greater than or equal to the number of miles Darla needs to drive, 120, divided by the number of miles per gallon her car gets, 37.5. This is because Darla wants to ensure that she has enough gasoline to make the trip, and she may not want to risk running out of gas on the way.

Another way to write this inequality is

g * 37.5 >= 120

This inequality represents the same meaning as before, we multiply g by the number of miles per gallon the car gets, 37.5 and it should be greater than or equal to the distance she needs to travel which is 120 miles.

Hence, the inequality can be written as g * 37.5 >= 120.

Since a triangle has three sides or three vertices, it is a polygon. It is a fundamental geometric shape. Triangle ABC is the moniker given to one of a triangle that has endpoints A, B, and C. When the points are not collinear, a singular plane and triangle are found in Euclidean geometry. A triangle is a polygon if it has three sections and three corners. The points where its three sides meet are known as the triangle's corners. The product of three triangle angles is 180 degrees.

The amount invested in each mutual fund is $400 and $1200 respectively

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 10 and 8x − 4y = 2

Let represent the amount the first fund get by x and the amount the second fund get by y.

Therefore x+y = 1600 equation 1

and 9/100 × x + 4/100 × y = 84

9x/100 + 4x/100 = 84

multiply through by 100

9x + 4x = 8400 equation 2

using elimination method

9x+ 9y = 14400 equation 3

9x + 4y = 8400 equation 4

subtract equation 4 from 3

5y = 6000

divide both sides by 5

y = 6000/5

y = $1200

substitute 1200 for y in equation 1

1200+x = 1600

x = 1600-1200

x = 400

Therefore the first fund will get $400 and the second fund will get $1200

What is arithmetic progression?

The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same amount. It also goes by the name Arithmetic Sequence.

We are given that the third term is 10.

This means that [tex]a_{3} =10[/tex]

So, n=3

Substituting this value in the given equations, we get

1)  [tex]a_{n}[/tex] = 8*3+10 = 34

2)  [tex]a_{n}[/tex] = 8*3 - 14 = 10  

3)  [tex]a_{n}[/tex] = 16*3+10 = 58

4)  [tex]a_{n}[/tex] = 16*3 - 38 = 10

So, the second and the fourth equation satisfy the condition.

We are also given that the fifth term is 26.

The rider has 141 laps left to finish the race.

If a rider has already cycled 4.75 km, and each lap measures 0.25 km, we can determine how many laps the rider has completed by dividing the distance already cycled by the distance per lap.

To find out how many laps the rider has left to finish the race, we will use the information on the total number of laps to complete the race: 160 laps.

The rider has completed:

4.75 km / 0.25 km = 19 laps

The rider has yet to finish:

160 laps - 19 laps = 141 laps

Answer:

Let x be the cost of the phone.

we know that the cost of the phone case is 10 times cheaper than the phone so the cost of the case is x/10

We also know that the total cost of the phone and the case is 660.

so we can write an equation:

x + (x/10) = 660

We can solve this equation for x by multiplying both sides by 10:

10x + x = 6600

11x = 6600

x = 600

So the cost of the phone is 600 and the cost of the phone case is 600/10 = 60

If rectangle is similarity to rectangle, to find the value of x we use proportion (c) 5/12 = 2/x.

When applying a scale factor, similar shapes are enlarged versions of one another.

All of the matching angles and lengths in related shapes are equal and in the same ratio.

If two figures share the same shape, congruent corresponding angles (which means the angles in the same places of each shape are the same), and identical scale factors, they are said to be "similar figures."

Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.

Thus, EF/JK = FG/KL

Since, EF = 5; JK = 12; FG = 2; and KL= x, therefore, the proportion to use in finding x would be:

The expression that does not show this relationship is P = l + w

It doesn't show the relationship because it doesn't take into account the two sides that are equal to the width and the two sides that are equal to the length.

Answer: To find the capacity of the tin can, we can use the formula for the volume of a rectangular prism, which is length x width x height. In this case, the length is 5 cm, the width is 4 cm, and the height is 15 cm. So the volume of the tin can is 5 x 4 x 15 = 300 cubic cm.

To find the capacity of the plastic cylinder, we can use the formula for the volume of a cylinder, which is pi x radius squared x height. The diameter of the circular base is 7 cm, so the radius is half of that, or 3.5 cm. So the volume of the plastic cylinder is pi x (3.5 cm)^2 x 10 cm = 385.4 cubic cm.

So the plastic cylinder has a greater capacity by 385.4 - 300 = 85.4 cubic cm.

On solving the question, unit rate by using the given graph could be 2.4 potatoes/pound

Graph can be defined as the visual representation which is used to represent the data.

The unit rate is the slope of the line.

The slope of the line =  (change in y-value)/(change in x-value)

= (36 potatoes - 12 potatoes)/(15 pounds - 5 pounds)

= (24potatoes)/(10 pounds)

= 2.4 potatoes/pound

The relationship here is proportional, so the line goes through the point (0, 0) and the unit rate can be figured from any point:

(12 potates)/(5 pounds)

= (24 potatoes)/(10 pounds)

= (36 potatoes)/(15 pounds) = 2.4 potatoes/pound

The polynomial h(x)=x^4+2x^3-13x^2-14x+24 in the factored form is (x−1)(x+2)(x−3)(x+4). The real roots of the polynomial is x= 1, x = 3, x = -2, x  = -4.

What is a polynomial function?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.

The polynomial function is -

h(x)=x^4+2x^3-13x^2-14x+24

Divide the polynomial h(x) by (x-1) -

(x^4+2x^3−13x^2−14^x+24)=(x−1)(x3+3x2−10x−24)

Divide (x^3+3x^2−10x−24) by (x+2) -

(x−1)(x^3+3x^2−10x−24)=(x−1)(x+2)(x^2+x−12)

Solve the quadratic equation x^2+x−12=0.

x^2+x−12=0

x^2+4x-3x-12=0

x(x+4)-3(x+4)=0

(x+4)(x-3)=0

So, (x−1)(x+2)(x^2+x−12)=(x−1)(x+2)(x−3)(x+4)

Therefore, x^4+2x^3−13x^2−14x+24=(x−3)(x−1)(x+2)(x+4) .

The Rational Root Theorem tells us that if the polynomial has a rational zero then it must be a fraction q/p, where p is a factor of the constant term and q is a factor of the leading coefficient.

We can see that p(1)=0 so x=1 is a root of a polynomial h(x).

Divide the polynomial by (x-1) -

(x^4+2x^3−13x^2−14x+24)/(x-1)=(x^3+3x^2−10x−24)

Divide (x^3+3x^2−10x−24) by (x-3) -

(x^3+3x^2−10x−24)/(x-3) = (x^2+6x+8)

To find the last zero, solve equation x+4=0

x=-4

Therefore, the real roots are - x = 1, 3, -2, -4.
