Ann and Ben translate documents from German into English. A set of documents that would take Ann 10 days would take Ben 12 days. Ann starts to translate the documents. After 2 days Ann and Ben both work on translating the documents. How many more days will it take to complete the work? You must show your working. Answer:
Using the together rate, it will take more 3.45 days to complete the work.
What is the together rate?The together rate is given by the sum of each separate rate.
For this problem, the rates are given as follows:
Ann: 1/10 = 0.1.Ben: 1/12 = 0.0833.Together: 1/x.Hence the amount completed in 2 days is:
2 x (0.1 + 0.0833) = 0.3666.
The amount it would take them to complete 100% of the project working together is found by the together rate as follows:
[tex]\frac{1}{x} = \frac{1}{10} + \frac{1}{12}[/tex]
[tex]\frac{1}{x} = \frac{6 + 5}{60}[/tex]
x = 60/11
x = 5.45 days.
The time it would take to do the remaining 100 - 36.66 = 63.34% of the project is:
0.6334 x 5.45 = 3.45 days.
It will take more 3.45 days to complete the work.

The scale on a map is 1:500000
Two towns are 7cm apart on the map
Work out the actual distance between the towns. Give your answer in kilometres
Answer:
Step-by-step explanation:
1: 500,000 cm
500,000cm can also be written as 5000m or 5 km
So it becomes 1:5km
the 1 represents 1cm on the map so every centimeter in the map is 5 kilometers in real life
If we want to get what 7 cm would be in kilometers then we have to multiply both sides by 7.
So it would be 1 x 7 and 5x 7
it would end up being 7 : 35 km
The answer is: 35km
Suppose that a function pairs elements from set A with elements from set B . Recall that a function is called onto if every element in B is paired with at least one element in A .
c. For the domain, is the function onto the set of nonnegative real numbers? Explain.
If a function is onto, then its domain can be a set of all non negative real numbers if the function is defined as y = √ x.
It is not necessary that function that is onto should have the domain as non negative real numbers only.
It can also have negative real numbers in its domain.
If the function is of the form:
y = √ x
Then the function will have a domain that is non negative real numbers.
But if function is of the form:
y = x²
Then it can have the domain as all real numbers.
Therefore, we get that, if a function is onto, then its domain can be a set of all non negative real numbers if the function is defined as y = √ x.

The length of AB is 2cm
From the question, we are to determine the measure of the angles and the length of line AB.
From the given information, we have that
Quad ABCD. is similar to Quad, EFGH
In the diagram,
Measure of ∠F = 60°
But, ∠B ≅ ∠F
∴ The measure of ∠B = 60°
Measure of ∠H
∠E + ∠F + ∠G + ∠H = 360° (Sum of angles in a quadrilateral)
From the diagram,
m ∠E = 90°
m ∠F = 60°
∠G ≅ ∠C
m ∠C = 75°
∴ m ∠G = 75°
Thus,
90° + 60° + 75° + ∠H = 360°
225° + ∠H = 360°
∠H = 360° - 225°
∠H = 135°
Hence, the measure of ∠H is 135°
Length of AB
The length of HE is twice the length of DA,

Given points are (2,-2) and (-3,-1)
Let A(2,-2), B(-3,-1)
We need to calculate the distance between two points.
We know that distance between two points means the length of the line segment that connects two points in the 2D plane.
The formula for finding the distance between the two points A(x₁, y₁),
B(x₂, y₂) in a plane is given by
D = √((x₂ - x₁)² + (y₂ - y₁)²)
Now we have two points A(2,-2), B(-3,-1)
By using the above formula we get the distance as
D = √((-3 - 2)² + (-1 - (-2))²)
D = √((-5)² + (-1+2)²)
D = √(25 + (1)²
D = √(25+1)

A small pool filled only with water will require an additional 300 gallons of water in order to be filled to 80% of its capacity. if pumping in these additional 300 gallons of water will increase the amount of water in the pool by 30%. what is the total capacity of the pool in gallons?
The total capacity of pool in gallons is 1625.
Let us assume the water in the pool be x liters. Forming the equation according as per the statement in question -
x + 300 = 80% of total volume - Equation 1
Forming the equation according to second statement -
30% × x = 300
30/100 × x = 300 - Equation 2
Finding the initial volume of water using equation 2-
x = 300×100/30
Cancelling zero and performing division and multiplication to find the initial volume of water
x = 1000 gallons
Now finding the total volume or capacity of pool by keeping the value of x in first equation -
1000 + 300 = 80/100 × total volume
Total volume = 1300×100/80
Performing multiplication and division to find the total capacity of pool
Total capacity of pool = 1625 gallons

Henry and emma want to buy a total of 0.5 yds of fabric. the fabric costs $8.72 per yard. how much will each pay if they want to split the cost evenly? $1.09 $2.18 $2.36 $4.36
If Henry and Emma want to buy a total of 0.5 yds of fabric and the fabric costs $8.72 per yard then the amount each will pay if they want to split the cost evenly is equal to $2.18.
The amount Henry and Emma will have to pay if they want to split the cost can be calculated by using division.
First, we calculate the cost of 0.5 yards of fabric.
1 yard of fabric cost = $8.72
0.5 yards of fabric cost = x
Here x is the cost of 0.5 yards of fabric
8.72 × 0.5 = x
x = $4.36
As the cost of 0.5 yards of fabric is calculated to be $4.36, the amount each will pay if they want to split the cost evenly can be found by dividing the cost of 0.5 yards by 2.
cost of 0.5 yards of fabric / 2 = 4.36 / 2 = $2.18.
Hence each one of them will pay $2.18 if they want to split the cost evenly.
