Good luck on your assignment
Think of the 2 in this problem as 2/1.
So we have 2/1 × 8/10.
Now we can cross-cancel the 2 and 10 to 1 and 5.
So we have 1/1 × 8/5 which is 8/5.

To rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]
Given the surd function:
[tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex]Rationalizing surd functions means multiplying the numerator and denominator of such function by the conjugate of the denominator.For the surd function given, to rationalize it, we only need to multiply the numerator and denominator by √11 as shown:
[tex]=\frac{2\sqrt{10} }{3\sqrt{11} }\times \frac{\sqrt{11} }{\sqrt{11} } \\=\frac{2\sqrt{110}}{3(11)}\\= \frac{2\sqrt{110}}{33}\\[/tex]

Math problem: Julie went shopping. She spent ⅙ of her money on books, ⅛ of her money on shoes and $5 on food. She had $13.50 left. Write an equation to represent this information. Solve the equation to find how much money she had at the beginning of the day?
Answers
Answer:
1/6+1/8+$13.50+$5=x
x=$18.79
Step-by-step explanation:
i add them
first i find the common denominator for 1/6 and 1/8
then i add 13.50 by 5
then add 18.50 by 7/24
i hope this explains how i got my answer
Answer:
Total amount of $ at beginning of day ⇒ ( About ) $ 26.1
Step-by-step explanation:
Let us say x represents ⇒ amount of $ at the beginning of the day;
If she spent 1 / 6 of this total money on books, we can say that the amount spent on books is 1/6x. Consecutively if 1/8 of this money was spent on shoes, the amount spent on shoes is 1/8x;
Knowing that $13.50 was remaining, let us set up the following equation;
x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ now let us solve for x,
x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ add similar elements, expanding,
x - ( 7/24x + 5 ) = 13.50 ⇒ distribute the minus sign
x - 7/24x - 5 = 13.50 ⇒ multiply either side by 24,
17x - 120 = 324 ⇒ add 120 to either side,
17x = 444,
Solution; Total amount of $ at the beginning of day ⇒ ( About ) $ 26.1
Write the equation of the graph which is the reflection of y=−|x−1|−1 about the origin
Answers
Answer:
f(x) = |x + 1| + 1
Step-by-step explanation:
A reflection over the y-axis followed by a reflection over x-axis is equivalent to a reflection about origin.
f(x) = -|x-1| -1
reflection over the x-axis:
-f(x) = (-1)*(-|x-1| -1) = |x-1| +1
reflection over the y-axis of the previous function:
-f(-x) = |-x-1| +1 = |x + 1| + 1
which is the reflection of f(x) about the origin
The following graph represents the hourly commission of a home appliance salesperson, y, based on the number of salespeople that are
working the showroom floor, x. The graph of the hourly commission of the salesperson is a quadratic function. What is the equation for
the function in standard form if the vertex is 6.5,42.25 and the origin is the only other known point?
Answers
We have been given graph of a downward opening parabola with vertex at point [tex](6.5,42.25)[/tex]. We are asked to write equation of the parabola in standard form.
We know that equation of parabola in standard form is [tex]f(x)=ax^2+bx+c[/tex].
We will write our equation in vertex form and then convert it into standard form.
Vertex for of parabola is [tex]y=a(x-h)^2+k[/tex], where point (h,k) represents vertex of parabola and a represents leading coefficient.
Since our parabola is downward opening so leading coefficient will be negative.
Upon substituting coordinates of vertex and point (0,0) in vertex form, we will get:
[tex]0=-a(0-6.5)^2+42.25[/tex]
[tex]0=-a(42.25)+42.25[/tex]
[tex]-42.25=-a(42.25)+42.25-42.25[/tex]
[tex]-42.25=-42.25a[/tex]
[tex]a=1[/tex] Divide both sides by [tex]-42.25[/tex]
So our equation in vertex form would be [tex]f(x)=-(x-6.5)^2+42.25[/tex].
Let us convert it in standard from.
[tex]f(x)=-(x^2-13x+42.25)+42.25[/tex]
[tex]f(x)=-x^2+13x-42.25+42.25[/tex]
[tex]f(x)=-x^2+13x[/tex]
Therefore, the equation of function is standard form would be [tex]f(x)=-x^2+13x[/tex].

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 5 child bikes and 15 adult bikes in the week.
No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Answers
Answer:
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Step-by-step explanation:
4c + 6a ≤ 120:
You can set up the inequality 4c + 6a ≤ 120, because it takes 4 hours to build per child bike (c) and 6 hours to build an adult bike (a), all together this time cannot surpass 120 hours. That is why you use the 'less than or equal to' sign.
4c + 4a ≤ 100:
You can then set up the inequality 4c + 4a ≤ 100, because it takes 4 hours to test a child bike (c) and 4 hours to test an adult bike (a). Since 100 hours is the max amount of time they can use to test out bikes, you will use the 'less than or equal to' sign.
4(5) + 6(15) = 20 + 90 = 110. 110 is less than 120
4(5) + 4(15) = 20 + 60 = 80. 80 is less than 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Answer:
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Kerri attends a 40-minute yoga class 5 times per week. How much time does she spend in the yoga class over a 7-week period?
Answers
Answer:
1,400 minutes
Step-by-step explanation:
First, let’s find how much time she spends per week.
She attends a class that is 40 minutes long and she does this 5 times a week.
Therefore, we can multiply 5 and 40 to find the total time per week.
5*40
200
She spends 200 minutes per week and she does this over a 7 week period.
We can multiply 200 and 7
200*7
1,400
She spends 1,400 minutes in yoga class over a 7 week period.
Answer:
1,400 minutes.
Step-by-step explanation:
Kerri attends a 40-minute yoga class 5 times per week.
Multiply 40 by 5 to get the total minutes for one week:
[tex]40*5=200[/tex]
So, Kerri attends yoga classes for 200 minutes total for one week.
With that in mind:
[tex]\text {Total Minutes for a Week} * \text {Weeks} =\\\rightarrow 200 * 7=\\\boxed {1400}[/tex]
Kerri should attend yoga classes for a 1,400 minute total in a seven week span.

Answer:
The difference of 12.4 and a quotient of and a number because when it says quotient it is talking about division and you are not dividing anything.
Step-by-step explanation:
"The difference of 12.4 and a quotient of and a number" is not a translation of the algebraic expression.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
An algebraic expression 12.4 - 36.
The equivalent expressions are:
1). 12.4 minus 3 times a number 6.
Let a = 6
That means, 12.4 - 3(6)
2). The product of 3 and a number subtracted from 12.4.
Let a = 6
That means, 12.4 - 3(6)
3). The difference of 12.4 and a quotient of and a number.
That means,
12.4 - 3/6
4). The difference of 12.4 and 3 times a number.
Let a = 6
That means, 12.4 - 3(6)
Therefore, "The difference of 12.4 and a quotient of and a number" is a required expression.

When the maximum value in a data set is exchanged for a higher

summary?
Answers
Answer:
It doesn't change any of the other numbers of the five number summary. Only the maximum value of the data set changes, out of the five number summary of the data set.
Step-by-step explanation:
The five number summary of any data set consists of five values which includes
- The maximum value of the data set.
- The minimum values.
- The lower quartile.
- The upper quartile.
- The median.
These values are usually presented together and ordered from lowest to highest: minimum value, lower quartile (Q1), median value (Q2), upper quartile (Q3), maximum value.
Replacing the maximum value with a higher number doesn't change any of the other five number summary as they all position markers, whose values do not change because of changes at one end of the distribution as the positions of the other variables n the dataset are untouched.
This means that, of the five number summary, only the maximum value of the data set changes.
Although, values like the range, mean and standard deviation also change too.
Hope this Helps!!!
There is no change in any of the other numbers of the five number summary.

Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 1 [tex]\frac{1}{2}[/tex] -(- [tex]\frac{1}{2}[/tex] ) = - 1
d = - 2 [tex]\frac{1}{2}[/tex] - (- 1 [tex]\frac{1}{2}[/tex] ) = - 1
d = - 3 [tex]\frac{1}{2}[/tex] - (- 2 [tex]\frac{1}{2}[/tex] ) = - 1

[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - [tex]\frac{1}{2}[/tex] and d = - 1 , thus

If the expression f^2+g^4-2f+1 is rewritten in the form a^2+(g^2)^2, what must be the value of a?
Answers
Answer: √(f^2 - 2f + 1) = a
Step-by-step explanation:
We have that:
f^2+g^4-2f+1 = a^2+(g^2)^2
And we want to find the value of a, so we should isolate it.
f^2 + g^4 - 2f + 1 = a^2 + g^(2*2) = a^2 + g^4
where i used that (x^y)^z = x^(y*z)
We can remove the term g^4 in both sides of the equation and get:
f^2 - 2f + 1 = a^2
now we can apply the square rooth to both sides and get
√(f^2 - 2f + 1) = a
So we just found the value of a.
