In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.
Simplify the expression by combining like terms. Then,
evaluate the expression by substituting the given values
for the variables.
x=5 and y=2
y^2 + xy – 7y^2
Answer:
-14
Step-by-step explanation:
The like terms in this equation is y^2 and -7y^2 so combining the two the equation becomes:
xy-6y^2
Then we substitute the values in:
5×2-6×2^2 = -14
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
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
Find the Distance rounded to a whole number.
Give the distance between (2,1) and (5,2)
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.

What is the length of the unknown leg of the right triangle rounded to the nearest tenth of a foot?
Answer:
Around 8.8
Step-by-step explanation:
This problem requires the Pythagorean Theorem. We are given the hypotenuse and a leg, so we can plug in what we know.
[tex]{x^2+2^2}=9^2 \\{4+x^2}=81 \\x^2=77\\\sqrt{x^2}=77\\x=\sqrt{77}\\x=8.8, approximately[/tex]

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?
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.
please do this for me

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that one-third of a number is at least 5 units from 31. The unknown number is x.
( 1 / 3 )x + 5 = 31
x + 15 = 31 x 3
x + 15 = 93
x = 93 - 15
x = 78
Therefore, one-third of the number is at least 5 units from 31. The number is 78.

Write a function rule in terms of x and y for the line that contains the points (-7.4, -9.7) and ( 8.4, 6.1) .
Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
