Which two ratios represent quantities that are proportional?
Answer:
D. 45/18 = 35/14Step-by-step explanation:
Lets simplify the ratios where possible and compare:
A. 3/4 = 9/12 ≠ 5/12B. 32/20 = 16/10 ≠ 22/10C. 7/5 = 14/10 ≠ 14/9D. 45/18 = 5/2 (divide by 9) and 35/14 = 5/2 (divide by 7)The last two ratios represent proportional quantities

Answer:
So is there are 10 cats for every 4 dogs,
If there are 5 cats that is half of 10 so half of 4 is 2
Now there are 32 dogs that is 8 times more than 4 so 10 x 4 is 40 so the answers are
Cats 10 5 8
Dogs 4 2 32

Give your answer in its simplest form
Answer:
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
[tex] \frac{130}{260} = \frac{1}{2} [/tex]
The fraction of the boys of Year 11 is 1/2.
What is a fraction?Fractions are used to represent smaller pieces (or parts) of a whole.
Given that, there are total 260 students of 11 years in which 130 are girls and 130 are boys.
The fraction of boys of 11 years = 130/260 = 1/2
Therefore, half of the strength of students are boys.
Hence, The fraction of the boys of Year 11 is 1/2.

The system of equations is graphed on the coordinate plane.
y=-5/3x+3
y=1/3x - 3
Enter the coordinates of the solution to the system of equations
in the boxes.
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.
Given constants a and b such that x2 + ax + b has factors (x + 7) and (x + 2) what is a?
Answer:
a=9 , b=14
Step-by-step explanation:
Just do the operation (x+7)(x+2)
x(x)+x(2)+7(x)+7(2)
x^2+2x+7x+14
x^2+9x+14
So a=9 and b=14

60% of 15 is what answer
Answer:9
Step-by-step explanation:
Think of it this way:
If 15=100%
then x= 60%
So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.
