If we are asked to to find the x-intercept of the graph given its equation, we substitute y = 0 into the equation, because:
The x-intercept is the point where the graph intersects the x-axis and hence the y-coordinate of that point will be 0
The y-intercept will be 0
The x-intercept is the point where the graph intersects the y-axis and hence the y-coordinate of that point will be 0
The x-intercept is always at (0, 0)

In the 2009-2010 school year in country A, there were 138,000 foreign students from country B. This number is % more than the number of students from country C. How many foreign students were from country C?
The number of students from country C using mathematical operations is 113,115.
What are the mathematical operations?The mathematical operations are addition, subtraction, multiplication, and division.
These mathematical operations are used to determine the output value, given some input values.
Data and Calculations:The number of foreign students from country B = 138,000
Students from country B are 22% more than the number of students from country C.
Assume that the number of students from country C = 100%
Then the number of students from country B = 122% (100 + 22)
If the number of foreign students from country B is 138,000, which is 22% more, then the number of students from country C is as follows:
The number of students from country C = 113,115 (138,000/1.22)
Thus, the number of students from country C using mathematical operations is 113,115.

The correct answer is option A that is 74.
First, we need to put the expression in the form of mathematical equation. A mathematical equation may be defined as the combination of numbers and arithmetic symbols which are related to each other according to the expression given. The expression in the form of mathematical expression can be written as:
(9 - 2/3×√9)² + (1-6)²
Solving the brackets separately.
(9 - 2/3×3)² + (-5)²
Now in the next step, simplify the equation.
=>(9 - 2)² + 25
=>(7)² + 25
=>49 + 25
=>74.
Therefore, the required answer is 74.

What is the least integer whose square root is an irrational number between 5 and 7? 13 6 25 26
Answer:
26
Step-by-step explanation:
Comment
Irrational means that the number cannot be represented as a fraction. This question means that the square root itself is between 5 and 7. Be careful how you read the question.
That means you have to take the square root of the given number and see where it lands.
√13 = 3.61 which is not between 5 and 7
√6 is going to be even smaller. Not the answer
√25 = 5 The question says between. Not the answer.
√26 = 5.09 which is greater than 5 and and less than 7

find the average of 1/8, 1/6, and 3/4
Answer:
Average= [tex]\frac{25}{72}[/tex]
Step-by-step explanation:
o find the average add up the values and divide the sum by the number of values.
Rewriting all values as fractions, rewriting any negatives if necessary and, setting up as an addition problem
= [tex]\frac{1}{8}[/tex] + [tex]\frac{1}{6}[/tex] +[tex]\frac{3}{4}[/tex]The least common denominator (LCD) is: 24.
Rewriting as equivalent fractions with the LCD:
= [tex]\frac{3}{24\\}[/tex] + [tex]\frac{4}{24}[/tex] + [tex]\frac{18}{24}[/tex]Rewriting numerators over the common denominator,
= [tex]\frac{3 + 4 + 18}{24}[/tex]Totaling the numerator:
= [tex]\frac{25}{24}[/tex]
Dividing by the number of values: 3
[tex]\frac{25}{24}[/tex] ÷3 =[tex]\frac{25}{24}[/tex] ×[tex]\frac{1}{3}[/tex] = [tex]\frac{25}{72}[/tex]
Average of the fractions is:
Average= [tex]\frac{25}{72}[/tex]
In 2008, the number of digital cameras shipped totaled 186 million. There were 24 million shipped in 2013. Find and
interpret the average rate of change in the number of digital cameras shipped per year.
Step-by-step explanation:
the average change rate for a function g(x) is defined for an interval of x values as
(g(interval end) - g(interval begin))/(interval end - interval begin)
in our case that is
(g(2013) - g(2008))/(2013 - 2008) =
= (24 mil. - 186 mil)/5 = -162 mil./5 =
= -162,000,000 / 5 = -32,400,000
that means that as a mean value there were 32,400,000 digital cameras shipped less every year.
in other words, fewer and fewer digital cameras are sold. the demand is strongly declining.
actually, following the mean values and their trend, there should have been no new digital cameras shipped in 2014 anymore (as 24 mil. - 32.4 mil is less than 0).

Suppose that you're designing a concrete patio. The patio will have height of 6 inches (1/2 foot) and have a rectangular base with a perimeter of 70 feet. If you have 138 cubic feet of concrete, what are the dimensions of the concrete patio?
The dimensions of the concrete patio should be 23ft x 12ft x 0.5feet.
What are the dimensions of an object?Since a rectangle is two-dimensional, while a cube is three-dimensional, the dimensions of the concrete patio include its length, width, and height or thickness.
Data and Calculations:The quantity of concrete required = 138ft³
The perimeter of the patio = 70 feet
Height = 6 inches or 1/2 foot or 0.5 ft
Perimeter = 2(L + W)
70 = 2(L + W)
L + W = 35 (70/2)
The possibilities for the length and width include 20 and 15, 25 and 10, and lastly, 23 and 12, which are also the two pair factors of 276.
Let L = 23 (the length is always longer than the width)
W = 12 (35 - 23)
Check:
Volume of concrete = 138ft³
Area = 276ft² (138ft³/0.5ft)
Two pair factors of 276 are 92 and 3, 46 and 6, 23 and 12, 2 and 138, and 1 and 276.
Given also that (23 + 12)2 = 70 (perimeter)
The dimensions that meet the two requirements are:
Length = 23 feet
Width = 12 feet
and Height = 0.5 feet
= 23 x 12 x 0.5 = 138
Thus, the dimensions of the concrete patio should be 23ft x 12ft x 0.5feet.

66) The number of feet of fencing that Ms. Hamilton needs to buy is 75 feet.
67) The distance around a rectangle is called a perimeter.
68) What are the instances of the use of Maths skills?The use of Mathematics skills is all-encompassing. Every activity involves some mathematical calculations and the use of mathematical operations, like additions, subtractions, divisions, and multiplication.
When you visit a Merchandise Store, you undertake some mathematical activities by computing how much is needed and the balance you will get. Future projections depend on maths skills.
For instance, budgeting how much it costs you weekly to maintain your hairstyle also involves maths skills.
As you return to school after the summer breaks, you decide how much savings you must spend. It is maths. Any time calculations are involved, it requires maths.
Data and Calculations:Length of the yard = 24.75 feet
Width of the yard = 12.75 feet
Perimeter of the yard = 75 feet (24.75 + 12.75)2
Charges for a yard of iron fencing = $50 per yard
3 feet = 1 yard
75 feet = 25 yards (75/3)
The cost of 25 yards = $1,250
Thus, Ms. Hamilton will need to spend $1,250 on this decorative iron fence project.

There are 496 black sedans in the parking lot and 640 non-black sedans in the parking lot. What is the ratio of non-black sedans to black sedans
Answer: the ratio is 1.13
Step-by-step explanation:
The ratio of non-black sedans to black sedans is 40/31, as of the given condition.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
The total number of sedans in the parking lot is,
496 black sedans + 640 non-black sedans = 1136 sedans.
The ratio of non-black sedans to black sedans can be found by dividing the number of non-black sedans by the number of black sedans:
Ratio = 640 non-black sedans / 496 black sedans
Ratio = 640/496
Ratio = 40/31
So, the ratio of non-black sedans to black sedans is 40/31.

∠1 and ∠2 form a linear pair. If m ∠1 is eight more than m ∠2 find the measures of both angles
A linear pair is formed of ∠1 and ∠2. The measures of the angle ∠1 is 20 and ∠2 is 160.
Given that,
A linear pair is formed of ∠1 and ∠2.
We have to find the measurements of both angles if m∠1 is eight more than m∠2.
When they refer to something as "linear," they mean that two angles create a straight line (or, 180 degrees). In other words, the two angles add up to 180.
Let us take the ∠1 as x
Then ∠2 will be 8x.
Now, we can write as
x+8x=180
9x=180
x=180/9
x=20
Therefore, the measures of the angle ∠1 is 20 and ∠2 is 8×20=160.
