Answer:

No.

Step-by-step explanation:

Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!

90 / 9 does equal 10, but 90 / -9 equals -10.

The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.

Thus, the correct answer should be -10.

If the perimeter of the equilateral triangle is 18 cm then the width of the rectangle be 11.2 cm.

Given that the perimeter of the equilateral triangle be 18 cm and the perimeter of all the three triangles be 46.4 cm.

We are required to find the width of the rectangle.

Rectangle is basically the shape which is having opposite sides equal to each other.

Perimeter of equilateral triangle=3 *side

3* side=18

side=18/3

side=6

Since it is on the length of the rectangle so the length of rectangle be

6 cm.

Perimeter of all the three triangles=2*width of the rectangle+1 length+perimeter of 1 equilateral triangle.

T1 and T2 are the other triangles.

Suppose the width of the rectangle be x.

Perimeter=2*x+6+18

46.4=2x+24

2x=46.4-24

2x=22.4

x=11.2

So,the width of the rectangle is equal to 11.2 cm.

Hence if the perimeter of the equilateral triangle is 18 cm then the width of the rectangle be 11.2 cm.

HELP MEEEEE<br> In complete sentences, describe the characteristics of this scatterplot.
Umnica [9.8K]

Step-by-step explanation:

Scatter plots are dots scattered all over the graph.  I think that this is the easiest graph because all you need to do is put a dot where you want it.

A scatter plot doesn't need any lines, all it needs is dots.

How do I find the slope of the line through (–9, –10) and (–2, –5)?
storchak [24]
Answer:
slope of line is 5/7

Explanation:
The slope of the line can be calculated using the following rule:
slope = \frac{y2-y1}{x2-x1}

The given points are:
(-9,-10) which represent (x1,y1)
(-2,-5) which represent (x2,y2)

Substitute with the points in the above equation to get the slope as follows:
slope = \frac{-5-(-10)}{-2-(-9)} = 5/7

Hope this helps :)
