Answer:

Approximately 57 minutes.

Step-by-step explanation:

5 ÷ 45 = 1/9

1/9 · 8.5 = 17/18

An hour = 60 mins so

60 ÷ 18 = 10/3

10/3 · 17 = 56.6666667

To find the area of a composite figure, you need to determine the areas of all the individual shapes that make up the composite figure and add them together.

The result will be the total area of the composite figure, expressed in square units.

Here are some steps you can follow:

Example: If the composite figure is made up of a rectangle with area 36 square units and a triangle with area 18 square units, the total area A would be 36 + 18 = 54 square units.

In this case, figure number 1, consists of two rectangles. To find the area of a rectangle, use the formula width x height. Follow these steps:

The Geometric Sequence if first term is 9 and common ratio is 3 is 9,27,81,243,729 .

What is Geometric Progression ?

Geometric Progression can be defined when in  a sequence of numbers , if the ratio between consecutive numbers is same than it is said to be in Geometric Progression.

Given

The first term is 9

and common ratio is 3

So, we need to find the geometric sequence ,

Geometric sequence, An  = a * r^(n-1)

so here a=9

r = 3

a1 = 9

a2 = 9 * 3^(2-1)

a2 = 9*3

a2 = 27

a3 = 9 * 3^(3-1)

a3 = 9 * 3 * 3

a3 = 81

a4 = 9 * 3^(4-1)

a4 = 9 * 27

a4 = 243

a5 = 9*3^(5-1)

a5 = 9 * 81

a5 = 729

The depreciation range ( Depreciated price) for 2021 RAV 4 LE FWD at $28,590 will be $17154-$20013 and for 2021 BMW Coupe 2-series at $45,500 will be $27300-$31850.

What is depreciation?

Almost everything we see around us has a useful life because it is being used up little by little every day or will become outdated as technology changes. Think about the computer you are using. You probably expect it to last only about five years because every time you access it, the components inside it get used up a little bit, and improved technology will eventually make it obsolete. This 'using up' is called depreciation, and that five years is considered the computer's useful life.

Now,

As given that average depreciation for cars is between 30% and 40%

that means their depreciated price will be between 60% and 70%.

Hence,

For 2021 RAV 4 LE FWD at $28,590

Depreciation range will be 60/100*28590 to 70/100*28590

i.e. $17154-$20013

For 2021 BMW Coupe 2-series at $45,500

Depreciation range will be 60/100*45500 to 70/100*45500

Answer:

To find the scale factor between the two similar figures, we can use the ratio of their surface areas. Similar figures have the same shape but different sizes, so their surface areas will be in proportion to the scale factor.

We are given that the surface area of the first figure is 169 cm² and the surface area of the second figure is 121 cm².

The scale factor is the ratio of the surface area of the first figure to the surface area of the second figure.

The ratio can be found by dividing the surface area of the first figure by the surface area of the second figure:

169 cm² / 121 cm² = 13/9

So, the scale factor between the two similar figures is 13/9

Therefore, the answer is 13:9.

The equation of line is y = -50x + 300 , where the slope is m = -50 and the time t when Alonso was 225 miles away was t = 1.5 hours

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 2 , 200 )

Let the second point be Q ( 5 , 50 )

Now , the slope of the line between the points is ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 200 - 150 ) / ( 2 - 5 )

Slope m = -150/3

Slope m = -50

And , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 200 = -50 ( x - 2 )

On simplifying the equation , we get

y - 200 = -50x + 100

Adding 200 on both sides of the equation , we get

y = -50x + 300

So , when Alonso is at 225 miles away ,

Substitute the value of y = 225 miles , we get

225 = -50x + 300

Subtracting 300 on both sides of the equation , we get

-50x = -75

Divide by -50 on both sides of the equation , we get

x = 75/50

x = 3/2

x = 1.5 hours

Hence , the equation of line is y = -50x + 300

Using Venn Diagram formula, 13 students ordered both food, 10 students ordered meat pie but not fried rice​.

A Venn diagram is a visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects. Circles that overlap share certain characteristics, whereas circles that do not overlap do not. Venn diagrams help to visually represent the similarities and differences between two concepts.

Using Venn diagram formula,

n(A U B) = n(A) + n(B) – n (A ⋂ B)

Given,

n(A U B) = Total students = 50

n(A) = 23 ordered meat pie

n(B) = 34 ordered fried rice

6 ordered neither meat pie nor fried rice

As 6 students ordered neither meat pie nor fried rice,

Total students = 50 - 6 = 44

According to n(A U B) = n(A) + n(B) – n (A ⋂ B)

⇒ 44 = 23 + 34 - n (A ⋂ B)

⇒ 44 = 57 - n (A ⋂ B)

⇒ - 57 + 44 = - n (A ⋂ B)

⇒ n (A ⋂ B) = 13

The two equations given, "Y = 5x - 9" and "X = y + 5", are a pair of linear equations. We can solve for the values of x and y by using substitution or elimination method.

Here's how to solve using the substitution method:

Y = 5x - 9

Y = (y + 5) + 5 - 9

5x - y - 4 = 0

y = 5x - 4

X = y + 5

X = (5x - 4) + 5

X = 5x + 1

5x + 1 = X

5x = X - 1

x = (X - 1) / 5

y = 5x - 4

y = 5((X - 1) / 5) - 4

y = X - 1 - 4

y = X - 5

So, the solution to the system of equations is (x, y) = ((X - 1) / 5, X - 5).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope of line passing through points (2, 5) and (–3, 5)

Step-by-step explanation:

The value of cos(A+B)​ is -4/5.

Suppose we've got trigonometric cosine of angle A and B measurements.

Then, we have:

[tex]\cos(A+B) = \cos(A)\cos(B) - \sin(A)\sin(B)[/tex]

If we get A = B, then:

[tex]\cos(2A) = \cos^2(A)- \sin^2(A)[/tex]

Given;

cosA=3/5

sinB=7/25

Now,cos(A+B) = cos A cos B - sin A sin B

for angle A 3^2+4^2 = 5^2

cos A = 3/5 so sin A = 4/5

for angle B 24^2 + 7^2 = 25^2

cos B = -24/25 and sin B = 7/25 because B is obtuse

Substituting the values in cos(A+B)​

=3/5*-24/25-4/5*7/25

=-72/125-28/125

=-100/125

=-4/5
