The proportions equal to the ratio 9 : 5 is given by the equation A = 18 : 10 , 27 : 15 and 36 : 20
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the equation will be
A = 9 : 5
Now , the proportion equivalent to the proportion A is given by
A = 9/5 be equation (1)
Multiplying the numerator and denominator by 2 , we get
A = 18/10
So , the value of A = 18 : 10
Now , Multiplying the numerator and denominator by 3 , we get
A = 27/15
So , the value of A = 27 : 15
Now , Multiplying the numerator and denominator by 4 , we get
A = 36/20
So , the value of A = 36 : 20
Hence , the proportion is 9 : 5

Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was 1 meter long. How long was each pipe?
Answer: 5cm
Step-by-step explanation:
First and foremost, we should note that
1 meter = 100 centimeters
Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:
= 100 / 20
= 5cm each.
Each pipe is 5cm long.

Work out the gradient of a line that passes through co-ordinates (3,4) & (6,16).
Answer:
4.33
Step-by-step explanation:
Given data
x1= 3
y1=3
x2=6
y2=16
M= y2-y1/x2-x1
substitute
M=16-3/6-3
M= 13/3
M=4.33
Hence the gradient is 4.33

PLEASE HELP I NEED THIS I AM GIVING LOTS OF POINTS!!!!!!!!!!! How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height 2 1/3 inches?
===================================================
Work Shown:
Let's find out how many smaller cubes are needed to go along the 2 & 2/3 inch side length of the bigger box.
First convert to an improper fraction
2 & 2/3 = 2 + 2/3 = 6/3 + 2/3 = 8/3
Divide this over the side length of the small cube to get
8/3 divided by 1/3 = (8/3)*(3/1) = 24/3 = 8
So we need exactly 8 small cubes along the 2 & 2/3 inch side length.
Let A = 8 so we can use this later.
------------------
Repeat the same steps for the 3 & 1/3 inch side length
3 & 1/3 = 3 + 1/3 = 9/3 + 1/3 = 10/3
10/3 divided by 1/3 = (10/3)*(3/1) = 30/3 = 10
We need 10 cubes along the 3 & 1/3 inch side length.
Let B = 10.
------------------
Repeat for the 2 & 1/3 inch side length
2 & 1/3 = 2 + 1/3 = 6 + 1/3 = 7/3
7/3 divided by 1/3 = (7/3)*(3/1) = 21/3 = 7
We need 7 cubes along the 2 & 1/3 inch side length
Let C = 7
------------------
Multiply out the values of A,B,C to get
A*B*C = 8*10*7 = 560
This means we need 560 cubes that are each 1/3 of an inch along the the side to fill up a box that has dimensions of 2 & 2/3 inches by 3 & 1/3 inches by 2 & 1/3 inches.
5. Which integer best represents a deposit of $37? *
A. 37
B. −37
C. −⎪37⎥
D. −⎪−37⎥
Answer:
A. 37.
Step-by-step explanation:
In B, that is making a withdrawal.
In C, because of the *||*s around it, this means that the number inside of those lines will always be positive. But the negative is outside of the lines so it is still negative.
In D, you might think that the |-37| cancels out the - on the outside. But like I said, those lines mean that anything inside of the lines will always be positive. Meaning that the |-37| inside just becomes |37| and still turns negative because of the - on the outside.
Hope this helped, the detailed explanation took a minute! :D

PLESE HELP MEE AND SHOWW YOUURR WOORKK PLEASE :)
Answer:
a) 13.4
Step-by-step explanation:
This will use the pythagorem theorm. Which is a^2 + b^2 = c^2. You'll start with 12^2 + 6^2 = c^2. Then you'll solve from there.
12^2 + 6^2 = c^2
144 + 6^2 = c^2
144 + 36 = c^2
180 = c^2
then you'll find the square root of 180 (i don't have that symbol on my keyboard)
/180 = c
6/5 = c
then in decimal form it's 13.4164...
so rounded it's 13.4
How do you find the diameter of a circle. Or what is the diameter of 56.52
Answer:
Assuming that the Radius is 56.52, the diameter would be 113.04
Step-by-step explanation:
The equation for finding diameter of a circle is r2 (I think) but it means Radius times 2, as radius if half of the diameter.
CAN SOMEONE HELP I WILL GIVE BRAINLIST PLEASE!
Answer:
1) Perimeter = 34 yards
If one of the width = 5 yards then the other width = 5 yards so 10 yards
34 yards - 10 yards = 24 yards divide by 2
Length = 12 yards
2) Perimeter = 24 m of fencing
Width = 7 m
2nd Width = 7 m
24 m - 14 m = 10 m divide by 2
Length = 5 m
3) The perimeter of a square is 12 feet
Note: All sides in a square is equal!
Side = 3 feet
4) The perimeter of a square pool is 30 feet
Note: All sides in a square is equal!
Side = 5 feet
3) When Jackie took her children to the movie theater, she bought one box of candy and three small drinks for
$14.75. When Alex went to the same theater and bought two boxes of candy and five small drinks, he paid
$26.
a) Set up a system of equations to model this situation. Be sure to define the variables that you use.
b) Determine, algebraically, the cost for one box of candy and one small drink
Answer:
c + 3d = 14.75
2c + 5d = 26
A box of candy is $4.25 and a drink is $3.50
Step-by-step explanation:
Let c represent the cost of a box of candy and let d represent the cost of a drink
c + 3d = 14.75
2c + 5d = 26
Solve by elimination by multiplying the top equation by -2
-2c - 6d = -29.5
2c + 5d = 26
Add them together
-d = -3.5
d = 3.5
Plug in 3.5 as d into one of the equations to solve for c
c + 3d = 14.75
c + 3(3.5) = 14.75
c + 10.5 = 14.75
c = 4.25
So, a box of candy is $4.25 and a drink is $3.50
If the simple interest on $7000 for 3 years is $1890, then what is the interest rate?
Answer:
0.09 or 9%
Step-by-step explanation:
I = Prt
Given:
I = 1890
P = 7000
t = 3
Work:
I = Prt
r = I/(Pt)
r = 1890/(7000 x 3)
r = 1890/21000
r = 0.09

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly.
Find the errors in her solution. What should her answer have been?
Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-1/2 = x
Answer:
22
Step-by-step explanation:
Answer:
1/2 = x
Step-by-step explanation:
8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (-13)
8x - 24 + 7 = -26x
8x - 17 = -26x
-17 = -34x
1/2 = x
