To find the perimeter, the equation is (w2 + l2 = p)

Where w is width and l is length and p is perimeter.

If you have the width, then you double it for both widths.

Then subtract that number from the perimeter.

150-60 = 90

90 is the remaining number for the lengths. Since both lengths needs to be equal, you split the 90. 45.

You length equals 45.

45(2) + 30(2) = Perimeter of 150.

Your answer is 45.

What are the intercepts of the graph of the equation 6 x − 1 . 5 y = 18?

WITCHER [35]

For this case we have the following equation:

$6x-1.5y = 18$

We find the intersections with the axes:

Intersection with the x axis:

Making $y = 0$ we have:

$6x-1.5 (0) = 18\\6x = 18\\x = \frac {18} {6}\\x = 3$

Thus, the intersection with the x-axis is: $(3,0)$

Intersection with the y axis:

Making $x = 0$ we have:

$6 (0) -1.5y = 18\\-1.5y = 18\\y = \frac {18} {- 1.5}\\y = -12$

Thus, the intersection with the y-axis is $(0, -12)$

Answer:

The intersection with the x axis is: $(3,0)$

The intersection with the y axis is: $(0, -12)$

A designer builds a model of a sports car. The finished model is exactly the same shape as the original, but smaller. The scale

lesantik [10]

Answer:

$Ratio = 2 : 15$

Step-by-step explanation:

Given

$k = 2 : 15$ --- scale factor

Required [missing from the question]:

The ratio of width of the model to the original

From the question, we understand that the scale factor is: 2 : 15

The ratio of the width of the model to the original equals the given scale factor i.e.

$Ratio = 2 : 15$

A ferry traveled 1/6 of the distance between two ports in

wel

First, we determine the speed of the ferry by dividing the distance by the time it took to cover that certain distance.

speed = (1/6) / (3/7)

speed = 7/18

Then, the distance it will travel for an hour is calculated through the procedure below.

distance = (7/18hour) x (1 hour)

distance = 7/18

Therefore, after an hour, the ferry will be able to travel 7/18 of the distance between two ports.
