The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 3 to 2 if there were 4440 total votes how many yes votes were there

Answers

Answer:

Y / N = 3 / 2

N + Y = 4440

Since Y = 3/2 N

3/2 N + N = 4440

5/2 N = 4440

N = 8880 / 5 = 1776

Y = 1776 * 3 / 2 = 2664

1776 + 2664 = 4440

2664  / 1776 = 3 / 2

Last night 30cm of snow fell in 6 hours. If it continues snowing at the
same rate, how long will it take for 45cm of snow to fall?​

Answers

Answer: 9 hrs for 45cm of snow to fall

Step-by-step

If 30cm = 6 hrs

Then divide 30/6 to get the unit rate of the amount of snow per hr

Which is 5/1

So 5cm per hr

Then add 30+5+5+5 to get 45

And since we know 5cm equal 1 hr

Add the original amount of hours which is 6 plus 3 ones

Which is 6+1+1+1

In total, it will take 9 hrs for 45cm of snow to fall.

Find the Distance rounded to a whole number.
Give the distance between (2,1) and (5,2)

Answers

Answer:

[tex]\sqrt{10}[/tex]

Step-by-step explanation:

The distance between two points can be found using the Pythagorean Theorem [tex]a^{2} + b^{2} = c^{2}[/tex].

This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates ([tex]x_{2} -x_{1}[/tex]) and the height by the distance between the y coordinates ([tex]y_{2} - y_{1}[/tex]). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.
