Let
x----------> number total of pictures

we know that
A------>25
B------> 4%----> 4/100------> 0.04x
C-----> 0.29------> 29%-------------------> 0.29x
D------> 27/100 --------> 27%--------------> 0.27x

[B+C+D]=4%+29%+27%--------> 60%
that means A=100%-60%---------> 40%
so
A-------------> 0.40x
A------>0.40 xB------> 0.04xC-----> 0.29xD------> 0.27x

the answer is
the photographers list in order from least to greatest by the amount of pictures they take is
B------> 0.04x
D------> 0.27x
C------> 0.29x
A------> 0.40x

What are the possible values of x and y for two distinct points, (5, –2) and (x, y), to represent a function?
bonufazy [111]

The <em><u>correct answer</u></em> is:

Any real number for x except 5, and any real number for y.

Explanation:

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.  This means that no x can be mapped to more than one y, so if we have the same number used twice for x, we do not have a function.

This means that 5 cannot be used for x in the other ordered pair.

Since there is no restriction on y in order to be a function, y can be any real number.

What are symbols of inclusion
Kipish [7]

Answer:

Symbols of inclusion are symbols used in mathematical expressions that group terms or factors together. They indicate that when we are simplifying expressions, we are to perform what's inside the symbols first. The three types of symbols of inclusion are parentheses, brackets, and braces.

A wine maker has 2 wine barrels labeled A and B. There is more wine in barrel A than in barrel B. The wine maker wants the 2 bar
Rudiy27

Answer:

Step-by-step explanation:

Gonna take this nice and slow.  First, at the end it says together both barrels have 48 pints when equal, which means added together they have 96.  This stays even as we  pout from one to the other.  So A+B = 96.  Keep that in mind.  Also I hope you're good with your systems of equations.

One step at a time.  We start with A and B

First, he doubles what is in B, which means he takes that much out of A.

A turns to A-B and B turns to 2B, hopefully you understand that.

Second A is doubled, which means that much is taken out of B.

A-B turns to 2(A-B) or 2A - 2B and 2B turns to 2B - (A - B) or 3B - A

Third and finally B is doubled again

2A - 2B turns to 2A - 2B - (3B - A) or 3A - 5B and 3B - A turns to 2(3B - A) or 6B - 2A

Now we have our system.

A + B = 96

3A - 5B = 6B - 2A or to make it a little nicer 5A = 11B

Let me know if you need help witht he system solving, but you wind up with

A = 66

B = 30

Again, let me know if you don't understand some part.
