Answer:
22 rows and 22 flags are needed
Step-by-step explanation:
Total number of vendors = 88
Existing number of rows and flags= 4
Number of rows and flags needed= 88/4 =22
Answer:
4rows and 16flags
Step-by-step explanation:
Since there were 88 vendors at the craft fair and 4flags on each rows. To set up equal number of vendors on each row, we will use the expression;
Number of vendors per row = Total number of vendors/total number of flags per row = 88/4 = 22 vendors
If there are 22 vendors in a rows and there are 88vendors in total, the total of rows will be;
Total number of vendors/number of vendors per row
= 88/22
= 4 rows
If there are four rows in total and 4flags in each row, the total of flags needed will be;
Total number of row × total flag per row
= 4×4
= 16flags
This shows that there are 4rows and 16flags were needed.
Answers
100 and 28.
Explanation
Factors are number that you can multiply to give a certain number.
For example, 2 × 3 = 6. In this case 2 and 3 are factors of 6.
∴ To get the factors of 2800, we have to find numbers that you can multiply to give you 2800.
2800 / 2 = 1400
∴ 2 × 1400 = 2800. ⇒ 2 and 1400 are factors of 2800.
2800/100 = 28
∴ 100 × 28 = 2800 ⇒ 100 and 28 are also factors of 2800. 2800 have many factors but two of them are 100 and 28.
Answer: The correct reason is (B) each input value is mapped to a single output value.
Step-by-step explanation: The given statement is:
"The graph of a function never has two different points with the same x-coordinate."
We are to select the correct reason for the above statement.
The definition of a FUNCTION is as follows:
In simple language, a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
That is, if y = f(x) is a function of a variable 'x', then we have
(A) The first statement is "the graph of a function cannot be a straight line."
The statement is false. For example, let us consider y = x + 2. Obviously, it is a function because every value of 'x' will result in only one value of 'y'.
Also, the graph here will be a straight line as shown in the attached figure (1).
(B) The first statement is "each input value is mapped to a single output value."
The statement is true according to the definition of a function.
(C) The third statement is "each input value is mapped to more than one output value."
The statement is false by the definition of a function.
(D) The fourth statement is "the graph of a function is a vertical line."
The statement is false. For example, if we consider the vertical line x = 2. Then, we see from the attached figure (2) that the points (x, y) = (2, 1), (2, 0), (2, 3), etc. all lie on the line.
This shows that one input value leads to infinitely many values of 'y'. Hence, this vertical line cannot be the graph of a function.
Thus, (B) is the correct statement.
