In the velocity - time graph, the value of t is 180 seconds

Velocity-time graph is a plot between Velocity and Time. It shows the Motion of the object that moves in a Straight Line. Magnitude of Velocity at a given instant is equal to its Instantaneous Speed. It is drawn for 1-D motion only and can take both positive and negative values.

The formula of speed by using the distance and time represented as

speed = distance / time

In the velocity time graph, we have we walked back home at constant speed of 2m/s

This can be represented mathematically as

2 = 150 / t - 105

solve for t in the equation

150 = 2(t - 105)

150 = 2t - 210

2t = 150 + 210

2t = 360

t = 360 / 2

t =  180 seconds

Based on the charged amount, Lupita drove 8.76 miles.

Let us assume the number of miles rode bh Lupita be x. Forming the equation now -

Total charge = flat rate + cost per mile × number of miles

Keep the values in above mentioned equation to find the value of x

40.03 = 6.75 + 3.20×x

Rewriting the equation with respect to x

3.20x = 40.03 - 6.75

3.20x = 33.28

Shifting 3.20 to Right Hand Side of the equation

x = 33.28 ÷ 3.20

Performing division on Right Hand Side of the equation

x = 8.76 miles

Thus, Lupita drove 8.76 miles.

Given,you rotate a triangle 270° counterclockwise about the origin.

Then you translate its image 2 units right and 1 unit down.

The vertices of the final image are (0, 2), (8,-1), and (5,-2).

we are asked to find  the vertices of the original triangle =?

Before translating the image of final image 2 units right and 1 unit down.

the vertices of the triangle is:

(0-2,2+1) → (-2,3)

(8-2,-1+1) → (6,0)

(5-2 , -2+1) → (3,-1)

{translate the final image 2 units left, 1 unit up again}

then before rotate 270° counterclockwise.

the vertices of the triangle is:

(-2,3) → (-3,-2)

(6,0) → (0,6)

(3,-1) → (1,3)

{rotate 270° clockwise again }

Hence the vertices of the original triangle is:

(-3,-2) (0,6) and (1,3)

The area of the given quadrilateral trapezoid ABCD with vertices A (-3,2) B (1,5) C (7,-3) D (0,-2) will be 37.5 square units.

A quadrilateral is a geometrical 2d shape with four sides, each side being connected and making a close polygon.

In other words, a quadrilateral is a polygon in which four sides, such as a trapezoid, square, and parallelogram, are quadrilateral.

As per the given quadrilateral as trapezoid,

The area of the trapezoid = 1/2 x (sum of parallel length) x perpendicular

The given trapezoid has been drawn below,

The length associated to two points (x₁, y₁) and (x₂, y₂)  is given by the formula;

[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

The smaller parallel line = 5 unit

Bigger parallel line = 10 unit

Perpendicular distance = 5 unit

Area = 1/2 x (5 + 10) x 5 = 37.5 unit square.

Hence "The area of the given quadrilateral trapezoid ABCD with vertices A (-3,2) B (1,5) C (7,-3) D (0,-2) will be 37.5 square units".

1. When a function passes the horizontal line test, we can infer that its inverse is both known and exists.

You can use the vertical line test to determine whether an expression is actually a function; if it succeeds, it is. If the graph does, in fact, pass the vertical line test before passing the horizontal line test, it is a function. If it also passes the horizontal line test, it is a one-to-one function, which means there is a unique x-coordinate value for every unique y-coordinate value. Only one-to-one functions have an inverse expression that is also a function.

Given that a photocopier takes 8s to make 20 copies and we need to find out how long would it take to make 45 copies .

This can be solved using Unitary Method as ,

To make 20 copies it takes 8 s.

To make 1 copy it would take 8/20 s

Hence to make 45 copies it would take 8/20*45 = 18s

And we are done!

Answer:

45 copies = 18 seconds

Step-by-step explanation:

Time taken to make 1 copy,

→ Total time ÷ Total copies

→ 8 ÷ 20

→ 8/20 seconds

Then the time taken for 45 copies,

→ 45 × (8/20)

→ (45 × 8)/20

→ 360/20

→ 18 seconds

Hence, time taken is 18 seconds.

The number of green fish are in the aquarium is 6.

Given that,

The aquarium has 3 more yellow fish than green fish.

60 percent of the fish are yellow.

Let us assume the green fishes be x and the yellow fishes are y.

Total no of fished = x + y.

And, y = x + 3

Based on the above information, the calculation is as follows:

Now, put y = x + 3

So,  

60%(y+x)=y

[tex]\frac{60}{100}(x+3+x)=x+3[/tex]

60(2x+3)=100(x+3)

120x + 180 = 100x + 300

What is an average gradient?

The gradient of a straight line drawn between two points is the average gradient between the two points.

Here, we have

A road has a gradient of 1/5 for 90 m.

Horizontal section 130 m long

The final section has a gradient of 1/5 for 200 m.

First, we will find the total height gained from start to finish

Total height from start to finish = 90 ×1/5 +200 × 1/5

= 18 + 40  

Total height from start to finish =58 m

The average gradient from start to finish = 58/(90 + 130 +200)

The first 100 natural numbers are 1,2,3,...,100 is 50.5.

An average is a single number chosen to represent a group of numbers; it is typically the sum of the numbers divided by the number of numbers in the group. The average of the numbers 2, 3, 4, 7, and 9 is, for instance, 5.

We know that the sum of the first n natural numbers is = 2n(n+1)

​Therefore, the sum of the first 100 natural numbers is = 2×100(101)

                                                                             =200(101)=20200

Hence, the sum of the first 100 natural numbers is = 20200  = 101
