Answers
Based on the ratio, 5¹/₂ : 1¹/₂, the unit rate can be found to be so the statement is TRUE.
How to find the unit rate?To find the unit rate of a ratio, you should divide the first number in the ratio by the second number in the ratio.
When given the ratio, 5¹/₂ : 1¹/₂, therefore, the unit rate is:
= 5¹/₂ ÷ 1¹/₂
= 11/2 ÷ 3/2
= 11/2 x 2/3
= 22 / 6
= 3.6667
= 3²/₃
In conclusion, the unit rate of 5¹/₂ : 1¹/₂ is 3²/₃.

Alejandro and some friends are going to the movies. At the theater, they sell a bag of popcorn for $3.50 and a drink for $4. How much would it cost if they bought 3 bags of popcorn and 8 drinks? How much would it cost if they bought p bags of popcorn and d drinks?
Total cost, 3 bags of popcorn and 8 drinks:______
Total cost, p bags of popcorn and d drinks:______
Answers
Answer:
Step-by-step explanation:
Using a proportional relationship, the costs are given as follows:
3 bags of popcorn and 8 drinks: $42.05.p bags of popcorn and d drinks: C(p,d) = 3.35p + 4d.What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
A proportional relationship may also involve multiple variables, as is the case in this problem, in which the cost is a function of the number of bags of popcorn p and the number of drinks d.
The constants are the prices of each product, hence the function for the total cost of p bags of popcorn and d drinks is given by:
C(p,d) = 3.35p + 4d.
Hence, for 3 bags and 8 drinks, the cost is:
C(3,8) = 3.35(3) + 4(8) = $42.05.

Phoebe, Andy and Polly share £270
Phoebe gets 3 times as much as Andy who gets twice as much as Polly
work out how much they get each?
Answers
Answer:
Phoebe=180
Andy=60
Polly=30
Step-by-step explanation:
let Polly be x
:Andy becomes 2x while Phoebe becomes 6x
therefore 6x+2x+x=270
9x=270
x=30
Hence: Phoebe=6x=180
Andy =2x=60
Polly=x=30
Reason:
Let Polly be x,
Hence Andy = 2x.
Then Pheobe = 6x [ie 3*(2x)]
Therefore, 6x + 2x + x = 270
Result x = 30
Pheobe gets 6x = 6*30 = 180
Andy gets 2x = 2*30 = 60
Polly gets x = 30
Total = 270

How to Translate a Sentence into an Equation?Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.
Thus, the sentence given can be translated as shown below:
The unknown number is represented as variable b.
"The sum of a number (b) and 3" would be translated as: b + 3.
"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).
Therefore, translating the whole sentence into an equation, we would have:
7(b + 3) = 1.

Find the area of parallelogram ABCD given mA = 30 and the following measures. AB = 6ft ; AX = 3 [square root] 3, A = ?
Answers
The area of the given parallelogram is: 9√3 sq. feet.
What is a parallelogram?A parallelogram is a simple quadrilateral with two sets of parallel sides in Euclidean geometry. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
Area of a parallelogram = Base of the Parallelogram * Height
Now, given:
A parallelogram ABCD,
AB = 6 feet, AX = 3√3. Angle A = 30°
To find: Area of the Parallelogram ABCD.
Finding: Here, AB = 6 feet = base
For height,
Height = perpendicular distance from X to AB
= AX(sinA)
Height = 3√3 (sin30) = 3√3 / 2
Thus, area of the parallelogram = [tex]\frac{3\sqrt{3}}{2}\times6= 9\sqrt{3}sq. feet.[/tex]
Hence, The area of the given parallelogram is: 9√3 sq. feet.

Answers
The rows of small jars of salsa are increased by 4 times.
The rows of ounces of salsa are increased by 32 times.
The pattern in the column of the table is
y = 8x
Therefore x = 4 then y = 8(4) = 32
x = 8 then y = 8(8) = 64
x = 12 then y = 8(12) = 96
x = 16 then y= 8(16) = 128.
x = 20 then y = 8(20) = 160.
The pattern in the column of the table is
y = 8x
Therefore x = 4 then y = 8(4) = 32
x = 8 then y = 8(8) = 64
x = 12 then y = 8(12) = 96
x = 16 then y= 8(16) = 128.
x = 20 then y = 8(20) = 160.
The relationship between ounces of salsa and small jars of salsa using a unit rate is
4 ounces = 1 serving
y = 4x
If x = 1 then y = 4
If x = 2 then y = 4(2) = 8
If x = 3 then y = 4(3) = 12
If x = 4 then y = 4(4) = 16
If x = 5 then y = 4(5) = 20
The relationship using the unit rate is
48 ounces = 4 medium jars of salsa.
For 1 medium jars of salsa = 48/4 = 12 ounces.
1 medium jar of salsa = 12 ounces.

Answers
The pool is full for 4 hrs.
Add the rates of filling of the 2 filling pipes and
subtract the rate of draining of the emptying pipe;
1st pipe's rate: ( 1 pool filled ) / ( 3 h);
2nd pipe's rate: ( 1 pool filled ) / ( 6 h );
3rd pipe's rate of emptying: ( 1 pool emptied ) / ( 4 h);
Let t = the time in hrs to fill the pool with all 3 pipes open
1/3+16-1/4 = 1/t;
Multiply both sides by 24t;
