To solve this question we need to convert all numbers into decimal system.
calculate:
1 can be written as 1.00
4/5 can be written as 0.8
-7/4 = -1.75
41% = 41/100 = 0.41
-1.3 can remain as it is because it itself is in decimal form.
Hence the order from greatest to smallest is as

Complete (assume $60,000 of overhead to be distributed): (Enter amount of overhead allocated as whole dollar amounts. Round your ratio answers to the nearest hundredth.) Sq. Ft. Ratio Amount of Overhead Allocated Dept. A 10,000 A B Dept. B 30,000 C D
The calculation of the ratios, resulting from the square feet occupied by Departments A and B, and the amounts of allocated overhead costs to the two departments are as follows:
Ratio Amount
Department A 1/5 $10,000
Department B 4/5 $40,000
What is the ratio?The ratio is the relative value relationship shared by two or more numbers.
Ratios are fractional values depicted in fractions, decimals, and percentages.
Like proportions, ratios show how much a value or variable is contained in another.
Total overhead = $60,000
Overhead Allocation:Department Square Feet Ratio Amount of Overhead Allocated
Dept. A 10,000 A = 1 B = $15,000 ($60,000 x 1/4)
Dept. B 30,000 = 3 D = $45,000 ($60,000 x 3/4)
Ratios = 10,000:30,000
= 1:3
Sum of Ratios = 4
Thus, based on the ratios, Department A is allocated $15,000, while Department B will be allocated $45,000 of the distributable overhead costs.

at a ratio of 4e:1a and having 60e: there are (60/4=15) 15 appetizers
at a ratio of 2e:1a and having 60e: there are (60/2=30) 30 appetizers
Because they already have 15 appetizers, they will need:
30 appetizers - 15 appetizers = 15 more appetizers

suppose v varies directly as g,and v=36 when x=4.Find v when g=11
Answer:
v = 99
Step-by-step explanation:
given v varies directly as g then the equation relating them is
v = kg ← k is the constant of variation
to find k use the condition v = 36 when g = 4 , then
36 = 4k ( divide both sides by 4 )
9 = k
v = 9g ← equation of variation
when g = 11 , then
v = 9 × 11 = 99
Tara and friends order a pizza. Tara eats 3 of the 10 slices and pays $4.50 for her share. If Tara has paid atleast her fair share, WRITE, and SOLVE to represent the cost of the pizza.
The equation that represents the cost of the pizza is 10x where x is the cost of one slice of pizza and the value of x is $15.
According to the question,
We have the following information:
Tara eats 3 of the 10 slices and pays $4.50 for her share.
Now, let's take the cost of one slice of the pizza to be $x.
So, we have the following expression:
3x = 4.50
Dividing by 3 on both sides of the equation:
x = 4.50/3
x = $1.50
Now, there are 10 slices in pizza.
Cost of pizza = 10x
Cost of pizza = 10*1.50
Cost of the pizza = $15
Hence, the equation that represents the cost of the pizza is 10x where x is the cost of one slice of pizza and the value of x is $15.

The value of the x is 60 km and the value of the y is 70 km.
Given that a man travels x km at 60 km/h and y km at 40 km/h and the total time traveled is 11/4 i.e 2.75 h.
Let's suppose that the time traveled for the x km is t1, time traveled for the y km is t2 and total time is T ,so by using the speed distance formula t1 & t2 will be :
t1 = x/60 and t2 = y/40 ;
T = t1 + t2;
i.e 2.75 = x/60 + y/40 ;
Multiply both sides with 120,
330 = 2x + 3y ............i
Now given that man traveled 5x km at 40 km/h and 3y km at 50 km/h in total time of 11. 7 hours. Similarly the equation for this situation will be :
T = t1 + t2;
x/8 + 3y/50 = 11.7 ;
Multiply both sides with 200, we will get

The operating income of Division B will increase by $640,000
How to calculate the increase in Division B's operating income?
Given that: Division B incurs variable costs of $10 per unit and a transfer price of $18 per unit is established between the two divisions and 80,000 units of materials are transferred to Division A
This cost of production by division B is:
cost = $10 × 80,000 = $800,000
Division B uses a transfer price of $18 per unit. That is:
Selling price = $18 × 80,000 = $1,440,000
Operating income increase = Selling price - cost
Operating income increase = $1,440,000 - $800,000 = $640,000
Therefore, Division B's operating income increase will be $640,000

30 years ago zoe was 2/3 as old as luke, 18 years ago zoe was 5/6 as old as luke how old are they now
Based on the mathematical statements, Zoe is 56 years old and Luke is 66 years old, now
How to determine how old they are now?From the question, we have the following statements that can be used in our computation:
30 years ago
Zoe was 2/3 as old as Luke
18 years ago
Zoe was 5/6 as old as Luke
Let their present ages be represented as
Zoe = x
Luke = y
So, we have the following representations
30 years ago
Zoe was 2/3 as old as Luke
x - 36 = 2/3(y - 36)
18 years ago
Zoe was 5/6 as old as Luke
x - 18 = 5/6(y - 18)
So, we have the following system of equations
x - 36 = 2/3(y - 36)
x - 18 = 5/6(y - 18)
Make x the subject in x - 18 = 5/6(y - 18)
x = 5/6(y - 18) + 16
Substitute x = 5/6(y - 18) + 16 in x - 36 = 2/3(y - 36)
5/6(y - 18) + 16 - 36 = 2/3(y - 36)
Open the brackets
5/6y - 15 + 16 - 36 = 2/3y - 24
Evaluate the like terms
5/6y - 35 = 2/3y - 24
Multiply through by 6
5y - 210 = 4y - 144
Evaluate the like terms
y = 66
Substitute y = 66 in x = 5/6(y - 18) + 16
x = 5/6(66 - 18) + 16
Evaluate
x = 56
Recall that
Zoe = x
Luke = y
So, we have
Zoe = x = 56
Luke = y = 66
Hence, they are 56 and 66 years, now

y = 120
x + y = 210
x + 120 = 210
x = 90
