Answer:
Between 3 and 3.5
Step-by-step explanation:
more than 9 and less than 16. 9 is closer to 10 making it c.
Go step by step to reduce the radical.
√ 128
√16 • √8
8 √2
8 √4 • √2
I think its 8×4√16
Explenation:
√128 = 11.3
√16×√8=6.3
8√2= 11.3
so i think you see the patern there and the answer should be 11.3 or 6.3
8√4×√2= 19
19÷2=9.5
9.5÷2=4.75
since 5 is too big to put in the equation and equal 128 then its 4.
To find the second one just do 4², which is 16
So yeah 8×4√16
Midway through the fundraiser, Mrs Little, the sponsor, discovers a container of buttermilk in the back of the fridge. It has 6 cups of buttermilk in it. How many recipes will this make? each recipe calls for 7/8. cup of butter milk.
Answer: 6 recipes
Step-by-step explanation: Just divide the 6 cups of buttermilk by 7/8 because each recipe need 7/8 cup of butter milk. You will get a number like this 6.857142857142857 (there are probably more decimals that come after it.) But, all the numbers after the 6 are useless because more recipes can't be made with those because you need at least 7/8 cups for one recipe. So, this will make 6 recipes. Hope this helps!

An electrician charges $75 per hour on top of a set fee of $50 for every house call. Write an equation for C, in terms of t, representing the total cost of the electrician's services if the electrician spends t hours at the house working.
C=?
Please help
Answer:
C= 75t + 50
This is the equation to use.
The equation that represents the total cost for a house will be C = 75t + 50.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
An electrical expert charges $75 each hour on top of a set expense of $50 for each house call.
Let 't' be the number of hours and 'C' be the total cost of the service. Then the equation is given as,
C = 75t + 50
The condition that addresses the all-out cost for a house will be C = 75t + 50.

Total consumption of fruit juice in a particular country in 2006 was about 2.05 billion gallons. The population of that country in 2006 was 500 million. What was the average number of gallons of fruit juice consumed per person in the country in 2006?
Answer:
4.1 gallons per person
Step-by-step explanation:
The total consumption of fruit juice is 2.05 billion
The total population is 500 million
Therefore the average number of gallons fruit juice consumed per person can be calculated as follows
=total consumption/total population
= 2,050,000,000/500,000,000
= 4.1 gallons per person

Consider the function represented by the equation x – y = 3. What is the equation written in function notation, with x as the independent variable?
f(x) = y + 3
f(x) = –y – 3
f(x) = –x + 3
f(x) = x – 3
Answer:
f(x) = x – 3
Step-by-step explanation:
The equation that is written in function notation, with x as the independent variable is D. f(x) = x – 3
Calculations and ParametersTo write the equation as an independent variable, we simply need to isolate y.
The next step would be to subtract x from both sides:
-y = 3 - x
To eliminate the -ve sign in y, we would divide both sides by -1
y= -3+x
If we rearrange, the answer would be:
f(x) = x – 3

Which of the following best describes the graph above?
OA. both a relation and a function
OB. function only
OC. neither a relation nor a function
OD. relation only
Answer:
The answer you are looking for is B) Function only.
Step-by-step explanation:
A function graph would mean that each x value corresponds to one y value, in a function multiple x values can have the same output but one x value cannot have more than one output.
A relative graph means each x value has their own unique output value and each x value (f(x)) has one output but cannot share that output with any other x value.
In this case x=5 which means it can only be a function.

At 5.45p.M .,lixin,khairul and Devil are at the starting point of a 1-km circular path. Lixin Takes 18 minutes to walk one round ,khairul needs 360 seconds to run 1 round ansd Devi cycles 2 rounds in 4 minutes .Find the time when all three of them will next meet
Answer:
[tex]Meeting\ Time = 6:03\ pm[/tex]
Step-by-step explanation:
Given
[tex]Start\ Time= 5:45pm[/tex]
[tex]Lixin = 18\ min/round[/tex]
[tex]Khairul = 360\ seconds/round[/tex]
[tex]Devi = 4minutes/2\ rounds[/tex]
Required
Determine their next meeting time
First, we need to get their unit rate in minutes per round
[tex]Lixin = 18\ min/round[/tex]
[tex]Khairul = 360\ seconds/round[/tex]
Convert 360 seconds to minutes
[tex]Khairul = \frac{360}{60} min/round[/tex]
[tex]Khairul = 6 min/round[/tex]
[tex]Devi = 4minutes/2\ rounds[/tex]
Divide by 2/2
[tex]Devi = 2mins/round[/tex]
So, we have:
[tex]Lixin = 18\ min/round[/tex]
[tex]Khairul = 6 min/round[/tex]
[tex]Devi = 2mins/round[/tex]
Next, is to determine the LCM of 18, 6 and 2
[tex]18=2 * 3 * 3[/tex]
[tex]6 = 2 * 3[/tex]
[tex]3 = 3[/tex]
Their LCM is:
[tex]LCM = 2 * 3 * 3[/tex]
[tex]LCM = 18[/tex]
This means that they will meet 18 minutes after their initial time of departure.
So:
[tex]Meeting\ Time = 5:45\ pm + 18\ minutes[/tex]
[tex]Meeting\ Time = 6:03\ pm[/tex]

The local high school is having tryouts for the cross country team. The school does not have a track, so the runners run around the school’s football field. The cross country coach determines that the width of the field is seventy yards shorter than the length.
Complete Question
The local high school is having tryouts for the cross country team. The school does not have a track, so the runners run around the school's football field. The cross country coach determines that the width of the field is seventy yards shorter than the length.
Part A
Write an expression that represents the perimeter of the football field. Let x Represent the length of the football field. Include parentheses in your expression. Next, write an equivalent expression that does not include parentheses.
Part B
The cross country coach later determines that the length of the football field is 120 yards. All students must run five laps. Using your answer from Part A, determine the actual number of yards that each athlete must run in the tryouts. In order to make the team, students must complete the laps in 6 minutes. How quickly must they run each lap?
Answer:
[tex]p=4A-140[/tex]
[tex]T =or 62sec[/tex]
Step-by-step explanation:
From the question we are told that
The width of the field is seventy yards shorter than the length.
a) Generally the equation for width and length is given as
[tex]B=x-70[/tex]
Mathematically in finding the perimeter [tex]p[/tex] around the field
[tex]p=2(A+B)[/tex]
[tex]p=2(2A-70)[/tex]
[tex]p=4A-140[/tex]
b)Generally[tex]A=120[/tex]
Mathematically
[tex]p= 4(120) -140[/tex]
[tex]p=480-140[/tex]
[tex]p= 340[/tex]
Therefore
Yards ran by individual athlete[tex]Y[/tex]
[tex]340*5=1700\\Y=1700[/tex]
Time elapsed in a lap T

Can a regular polygon have an interior angle of 132 degrees?
Given:
The interior angle of a regular polygon is 132 degrees.
To find:
The given statement is possible or not.
Solution:
Let as assume the interior angle of a regular polygon with n vertices is 132 degrees.
Then, the exterior angles are
[tex]180^\circ-132^\circ=48^\circ[/tex]
We have, n vertices. So, the number of exterior angles is n.
Sum of all exterior angles = 48n degrees
We know that, sum of all exterior angles of a regular polygon is always 360 degrees.
[tex]48n=360[/tex]
[tex]n=\dfrac{360}{48}[/tex]
[tex]n=7.5[/tex]
Number of vertices is always a whole number. So, it cannot be a fraction value.
So, our assumption is wrong.
Therefore, a regular polygon cannot have an interior angle of 132 degrees.

Simplify the sum on the denominator, that is
[tex]\frac{1}{x+2}[/tex] + [tex]\frac{1}{x+3}[/tex]
multiply numerator/ denominator of first fraction by x + 3
Multiply numerator/ denominator of second fraction by x+ 2
= [tex]\frac{x+3}{(x+2)(x+3)}[/tex] + [tex]\frac{x+2}{(x+2)(x+3)}[/tex]
= [tex]\frac{2x+5}{x^2+5x+6}[/tex]
The original fraction is now
[tex]\frac{1}{\frac{2x+5}{x^2+5x+6} }[/tex]
= 1 × [tex]\frac{x^2+5x+6}{2x+5}[/tex]
= [tex]\frac{x^2+5x+6}{2x+5}[/tex] → B
