Ten yards of a particular kind of wire cost $15.30 . What is the cost of the wire per foot?
Answers
Given:
Length of wire = 10 yards
Total cost of wire = $15.30
To be able to determine the cost of wire per foot, let's first convert the unit of measure of the wire's length from yards to feet.
Recall: 1 yard = 3 feet
Step 1: Convert the measure of the wire length from yards to feet.
[tex]\text{ 10 (yards) x }\frac{\text{ 3 feet}}{\text{ 1 (yard)}}\text{ = }\frac{\text{10 x 3}}{\text{ 1}}\text{ feet}[/tex][tex]\text{ = 30 feet}[/tex]Therefore, 10 yards is equivalent to 30 feet.
Step 2: Divide the total cost by the total length of wire in feet.
[tex]\text{ Cost of wire per foot = }\frac{\text{ Total cost of wire}}{\text{ Total length of wire}}[/tex][tex]\text{ = }\frac{\text{ \$15.30}}{\text{ 30 feet}}[/tex][tex]=\text{ \$0.51 per foot}[/tex]Therefore, the cost of the wire per foot is $0.51

Find the amount and the percent increase. Fill in the chart
Answers
Answer:
Amount of increase = 60
Percent of increase = 40%
Explanation:
The amount of increase is equal to the difference between the new amount and the original amount. So, it is equal to:
New amount - Original amount = 210 - 150 = 60
Then, the percent of the increase is equal to the amount of increase divided by the original amount, so:
Amount of increase/Original amount = 60/150 = 0.4
Therefore, the answers are:
Amount of increase = 60
Percent of increase = 0.4 = 40%
Find an ordered pair (x, y) that is a solution to the equation.
4x-y=5
(x,y) = ( , )
Answers
Ordered pair for the equation 4x-y=5 which is a solution of a given equation is (0,-5).
An ordered pair refers to a pair of two numbers or variables written inside the bracket and separated by comma.
To find an ordered pair of a equation we just need to find the values of x and y which will satisfy the given equation.
Here given equation is 4x-y=5
So we will put x=0 and y=-5
⇒ 4(0)-(-5)=5
Therefore (0.-5) satisfy given equation.
Hence (0.-5) is an ordered pair of 4x-y=5.
Note:- There are many ordered pairs that satisfy the given equation.

Given the graph that shows the results of the survey, you know that it shows the results of 3 price surveys conducted at 4 area supermarkets in 3 months.
Notice that the white bar represents the results of September, the dashed bar represents the results in November and the black bar represents the results in March.
You can identify that on the x-axis are written the 4 area supermarkets and, on the y-axis are represented the prices in dollars.
Therefore, in order to identify the supermarket that lowered the price of the frozen beef dinners by the greatest dollar amount between September and November, you need to identify the supermarket that has the shortest dashed bars and white bars.
In this case, you can identify that the lowest price in September and November is:

What is the meaning of the slope of the equation in this context?
Answers
ANSWER
It is the cost for printing each DVD
EXPLANATION
We want to find out what the slope of the equation represents.
The equation given is a linear equation. The slope of a linear equation represents the rate at which the dependent variable changes with respect to the independent variable.
The independent variable is the number of DVDs while the dependent variable is the cost to make the DVDs.
Hence, the slope represents the cost of the DVDs per DVD. In other words, it represents the cost for printing each DVD.
Write two fractions where the denominator of one is a multiple of the denominator of other

The two fractions are; 1/3 and 1/9.
What is a fraction?A fraction has two parts: Numerator and Denominator.
It is in the form of a Numerator / Denominator. A fraction is a numerator divided by the denominator.
We need to write two fractions where the denominator of one is a multiple of the denominator of the other.
Let's consider the first fraction as;
1/3
Then other fraction must be multiple of the denominator of the other.
So, it can be 1/9
We can see that "the denominator of one is a multiple of the denominator of other".
Thus the two fractions are; 1/3 and 1/9.
