they will approximately require 4.4 days to complete the remaining work together.
Ann alone take = 10 days to translate a document.
Work done in 1 day by Ann = 1 / 10
In 2 days = 2 / 10
Work left = 8 / 10
Now, Ben alone take = 12 days to translate a document.
Work done in 1 day by Ben = 1 / 12
We will now use addition.
Combined work of both Ann and Ben in 1 day = 1 / 10 + 1 / 12 = 11 / 60
Time taken to complete the rest of the work = 8 / 10 ÷ 11 / 60
= 48 / 11 = 4.4 days.
Therefore, they will approximately require 4.4 days to complete the remaining work together.

*Note, my question had Ann as 8 days and Ben as 12, so adjust accordingly*
Answer:
3 3/5
Step-by-step explanation:
After 2 days, 1/4 are done so 3/4 are left
1/8 + 1/12 = 10/48
3/4 ÷ 10/48
3/4 × 48/10 = 144/40 = 3 24/40 = 3 6/10 = 3 3/5

Suppose that E and F are points on the number line.
If EF=15 and E lies at 4, where could F be located?
If there are several locations, separate them with commas.
When E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.
We are given that:
E and f are the points on a number line.
We are also given that the distance between E and F is:
EF = 15 units
Now, we know that E lies at 4
E = 4
We need to find the location of the point F
Now, since we also know that:
EF = F ± E
Substituting the values:
15 = F ± 4
We get that:
15 = F + 4 or 15 = F - 4
F = 15 - 4 or F = 15 + 4
F = 11 or F = 19
Therefore, we get that, when E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.

The domain and range of of the graph in interval notation are [-4,3) and (-5,5).
Domain and range of a graph.The domain are the independent variables for which an expression or equation exists while the range are the dependent variables for which an expression or equation exists.
The given graph is a piecewise function since there are several lines that make up the graph.
Te domain are values of the function lying along the x-axis of the line graph while the range are values of the function along the y-axis of the line graph.

Answer:
4, 3, 0
Step-by-step explanation:
Let f(y)=x.
[tex]x=-\frac{1}{2}\sqrt{y+3} \\ \\ -2x=\sqrt{y+3} \\ \\ 4x^2=y+3 \\ \\ y=f^{-1}(x)=\boxed{4}x^2-\boxed{3}[/tex]
The domain of the inverse is the same as the range of the original function. For the original function, we know that it is decreasing, so the range is

From these problems, we have that:
The algebraic expression is: 10 + 9y.When y = 3, the expression has a value of 0.The quotient between two numbers is the division between them(it is not clear which numbers are in the quotient).What is the equivalent algebraic expression?The product of 9 and y is given by 9y.10 more than the expression is 10 added to the expression, hence 10 + 9y.Hence the algebraic expression is: 10 + 9y.
How to find the numeric value of a function/expression?To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the expression is:
(10 - 3y) - 1.
When y = 3:
(10 - 3 x 3) - 1 = 1 - 1 = 0.

11h-5(h+3)=-63 find they value of h
Answer:
h = -13
Step-by-step explanation:
Use PEMDAS to solve this problem.
11h - 5(h + 3) = -63
~Use distributive property to simplify [ a(b + c) = ab + ac ]
11h - 5h + 15 = -63
~Combine like terms
6h + 15 = -63
~Subtract 15 to both sides
6h = -78
~Divide 6 to both sides
h = -13
Best of Luck!
Answer:
Step-by-step explanation:
11h - 5(h + 3) = -63
-Multiply parenthesis so
-5(h) + -5(3) = -5h - 15
New equation: 11h - 5h - 15= -63
+15 +15
(add 15 to both sides)

Point B ∈ AC . Find the lengths of segments AB and BC if AC = 20 cm
The length of the segments AB and BC if AC = 20 then:
AB = 12cm

What is the simplest definition of a line segment?In geometry, a line segment is defined as two different points on a line. In contrast, a line segment is a piece of a line that connects two points. A line has no endpoints and runs indefinitely in both directions, whereas a line segment has two fixed as well as definite endpoints.
Is there a distinction between a line segment as well as a ray?Yes. A ray is not the same as a line segment. A ray has one endpoint, but a line segment has two. The ray's one end extends indefinitely, whereas the endpoints of a line segment are always specified and fixed.
According to the given data:We know that:
a:b=c:d as a/b=c/d
AB:BC = 3:2
is AB/BC=3/2
AB=3/2*BC
AC=20=AB+BC

A computer programmer receives a weekly wage of $1350, and &229.50 is deducted for income tax. Find the percent of the computer programmer’s salary deducted for income tax.
The percent of the computer programmer’s salary deducted for income tax is 17%.
What is percentage of a number?
A percentage is a ratio or number that can be expressed as a fraction of 100. In order to calculate a percentage of a number, we must divide it by 100 and then multiply the resulting number by 100. The proportion therefore denotes a component per 100. A percentage of one hundred is what is meant by the word "percent."
Given, weekly wage is $1350 and deduction amount for income tax is $229.50.
The percent of deduction is
[tex]\frac{229.50}{1350} \times 100\\=0.17 \times 100\\=17[/tex]
