20 points due in a hour : ( show how you got the answer tomas asked 15 students whether summer break should be longer. he used his calulator to divide the number of student who said yes to the total number of students. his calculator showed result as 0. a. write this number as a fraction. b. how many students said that summer break should be longer?

well we know the fraction must be out of 15.

so keep plugging in numbers (1-15) out of 15 to see which equals 0.933...

14/15 = 0.9333... after some strenuous work with a calculator.

this means 14 students said "yes" to summer break should be longer

just in case you didnt follow along: A. 14/15, B. 14 students

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
