Solve the following

Using the relation between velocity, distance and time, the equation that relates x and y is given by:

x + y - 3 = 0.

Velocity is distance divided by time, hence:

[tex]v = \frac{d}{t}[/tex]

In this problem, he wants to run 30 km at a rate of 10 km per hour, hence:

[tex]10 = \frac{30}{t}[/tex]

10t = 30

t = 3.

The total time is 3 hours. Considering x as the number of hours he runs and y the number of hours he walks, along with the total time, the equation is given by:

x + y = 3.

In standard form:

x + y - 3 = 0.

Step-by-step explanation:

You need to multiply the surface of the 'base' with height

Answer: 451 cm³

Step-by-step explanation: the rule of the volume is base times height so multiply 41

times 11 so the answer is 451 . The units is to the power of 3 in finding volume of figures . The hexagon is the base and the rectangle is the height so multiply their lengths and don't forget the units . Hope this helps .

Answer:

Step-by-step explanation:

The length of the rectangle is determined as x - 5 while the width is x² + 3.

The length of the rectangle is determined by the following formula shown below;

Area = Length x width

L = A/w

           x  - 5

          ------------------------------------

x² + 3 √x³ - 5x² + 3x - 15

           -(x³  + 3x)

        --------------------------

             - 5x²  - 15

              -5x² - 15

        ----------------------------

                     0

Thus, the length of the rectangle is determined as x - 5 while the width is x² + 3.

Answer:

C.

Step-by-step explanation:

In a function, one x-value must have just one y-value assigned to it. So in short, C is the only table that does not represent a function because it has two values of Y (-3, and -1) for one value of x (1).

Answer:

40mph

Step-by-step explanation:

use the speed = distance/time formula.

1. The first car has a speed of 30mph and travels one mile so the equation can be written as 30mph = 1/t.

Rearrange to get t = 1/30

1/30 of an hour is 2 minutes.

2. The second car has a speed of 60 mph and travels one mile so the equation can be written as 60mph = 1/t

Rearrange to get t = 1/60

1/60 of an hour is 1 minute.

The time it took for the total journey is 1 + 2 = 3 minutes

Writing 3 minutes as a fraction of an hour:

3/60 = 1/20

So using the s = d/t formula to calculate the average speed the formula can be written as (the speed is unknown, time is 1/20 and the distance is 2 miles):

Speed = 2/(1/20) = 2x20/1 = 40

Therefore the average speed of that car is 40 mph.

The point P is located on the second partition, when segment AB is divided into 5 subsegments

The ratio is given as:

AP : PB = 8 : 12

Simplify the ratio i.e. divide by 4

AP : PB = 2 : 3

The above ratio means that when the segment AB is divided into 5 equal segments, the point P is located on the second partition

Answer: Counter, 0, 0.

Step-by-step explanation:

Think about a clock. The hand of a clock goes clockwise. When you tighten something (righty tighty) you spin it clockwise. You can rotate an object, lets say a square, clockwise. You can also rotate it counterclockwise, in the other direction. Therefore, you can rotate an object clockwise and counterclockwise.

You can rotate a figure around any point, such as the center of the figure, the origin, or anywhere else. One common place to rotate a figure around, such as a square, is the origin. This is the center of the coordinate plane. This point is not up, down, left, or right at all from the center. This coordinate is (0, 0). Therefore, the next two blank spaces should both be filled with 0.

The blank spaces should look like this:

One direction is clockwise and the other is counterclockwise.

...

This can be any coordinate point such as the origin which is at ( 0 , 0 )

The Perimeter of the Field with a rectangular area of 1764 m² and the given width is; D: 170 m

We are given;

Area of rectangle; A = 1764 m²

We are told that the width of the field is 13 m more than the length. Thus;

W = L + 13

Thus;

L(L + 13) = 1764

L² + 13L = 1764

Using quadratic equation calculator;

L = 36 m

Thus;

W = 36 + 13

W = 49

Perimeter = 2(L + W)

Perimeter = 2(49 + 36)

Perimeter = 170 m
