Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to point distance. the calculation is: d
Ronch [10]

we are given two points as

(1.0, 2.0) and (1.0, 5.0)

so,

(x1, y1)= (1.0 , 2.0)

(x2, y2)= (1.0 , 5.0)

x1=1 , y1=2

x2=1 , y2=5

now, we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

and we get

d=\sqrt{(1-1)^2+(5-2)^2}

d=\sqrt{(0)^2+(3)^2}

d=\sqrt{(3)^2}

d=3

so, distance between points is 3...........Answer

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
AlekseyPX

Answer:

No Solution

Step-by-step explanation:

If you grouped like terms, you would get n+(-n)+5-10=1

Both <em>n's</em> would cancel each other out.

I hope this helps! (If it's wrong, then tell me, I'll try to find the correct answer...)

You ask 120 randomly chosen students to name their favorite ice cream flavor. There are 1800 students in the school. Based on th
Stella [2.4K]
39/120 = x / 1800....39 choc. chip to 120 students = x choc. chip to 1800 students

now we cross multiply because this is a proportion
(120)(x) = (39)(1800)
120x = 70200
x = 70200/120
x = 585 <===

or u could do it this way as well...
39 out of 120 picked chocolate chip....
39/120 = 0.325 = 32.5%....so 32.5% chose chocolate chip.

32.5% of 1800 = 0.325(1800) = 585 <==
