Radical Expressions
Melissa multiplied [tex]\sqrt{a}[/tex] and [tex]\sqrt{b}[/tex] and got a rational number.
We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.
We can write that product like:
[tex]\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}[/tex]
If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.
Answer: B. It is a perfect square

1) You are taking a Tae Kwon Do class that costs $15 a month. In addition, you needed to
purchase a uniform. You paid a total of $108 after 6 months. Write an equation that glves
the total cost (in dollars) as a function of the length of time you have been taking classes
(in months). Find the total cost after 9 months.
Answer:
$162
Step-by-step explanation:
you divide 6 months by 2 then you divide 108 by 2 then you add the half of 108 and plus it to 108 then you get your total.
The function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135
What is unit rate?A unit rate means a rate for one of something.
Given that, You are taking a TAE Kwan Do class that costs $15 a month. In addition, you needed to purchase a uniform. You paid a total of $108 after 6 months.
We have unit rate = $15 per month
Since, one month cost is $15 therefore, for 6 months = 15×6 = $90
Therefore, cost of uniform = $108 - $90 = $18
Let you are taking classes for x months, the function of the length of time you have been taking classes,
f(x) = 15x
For 9 month cost =
f(9) = 15×9 = 135
Hence, the function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135

Write the equation of the line that passes through the points (-7,1) and (7,-6).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y-1=-1/2(x+7)
Step-by-step explanation:
Find the slope first using the slope formula.
y2-y1/x2-x1
-6-1/7--7
-7/14
Slope is -1/2
Now choose one of the coordinates and put it in point-slope form.
y-1=-1/2(x+7)
Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
Answer:
The result of the correct substitution gives:
x = 3/7 and y = 27/7
Step-by-step explanation:
From the given information:
y = 2x + 3 ---- (1)
3x + 2y = 9 ---- (2)
By using substitutional method
Substitute the value of y = 2x +3 into equation (2)
So,
3x + 2(2x + 3) = 9
3x + 4x + 6 = 9
7x = 9 - 6
7x = 3
x = 3/7
From equation (1), let replace the value of x to be 3/7
So,
y = 2x + 3
y = 2(3/7) + 3
y = 6/7 + 3
y = 27/7
In a logistic regression model, the predictor _________
a. is interval/ratio data.
b. must undergo a logarithmic transformation before undergoing logistic regression.
c. must be in the range of 0 to 1
d. represents ranked scores
e. must be a binary variable
Answer:
B. must undergo a logarithmic transformation before undergoing logistic regression.
Step-by-step explanation:
A logistic regression model allows us to establish a relationship between a binary outcome variable and a group of predictor variables. It models the logit-transformed probability as a linear relationship with the predictor variables.

please help!! which triangle is similar to ABC?
A. Triangle A
B. Triangle B
C. Neither
D. Both
Answer:
triangle A because the measurements would be the same. If you add 30 + 112, you get 150. Triangles add to 180, so the missing angle of the first one is 30.
this means triangle A has the same measurements as ABC
In a dance contest in which 53,000 votes were cast, the winner received 3/5 of votes. How many votes did the winner not receive? (Incorrect solution: 3/5 x 53,000 = 3/5 x 53,000/1 = 3x53,000/ 5 x 1 = 31,800) ( explain error please and add correct work/solution and if you could share a strategy you used? Thanks!!)
Answer:
21,200
Step-by-step explanation:
Votes casted = 53000
Votes received = 3/5
Votes did not receive = 1- 3/5 = (5-3)/5 = 2/5
Total votes not received by winner
= 53000 *2/5
= 10,600 * 2
= 21,200
Ms. Van Tress has 134 students. She sees 38 students before lunch and 96 students after lunch.
What percentage of her students does she see before lunch? After lunch? (Round your answers to
the nearest whole number percent)
Answer:
[tex]\%Percent = 28\%[/tex] ---- Before Lunch
[tex]\%Percent = 72\%[/tex] --- After Lunch
Step-by-step explanation:
Given
[tex]Total = 134[/tex]
[tex]Before\ Lunch = 38[/tex]
[tex]After\ Lunch = 96[/tex]
Required
Determine the percentage of students seen in both cases.
This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%
i.e
[tex]\%Percent = \frac{Seen}{Total} * 100\%[/tex]
- Before Lunch;
[tex]\%Percent = \frac{Before\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{38}{134} * 100\%[/tex]
[tex]\%Percent = \frac{3800\%}{134}[/tex]
[tex]\%Percent = 28\%[/tex] --- approximated
- After Lunch;
[tex]\%Percent = \frac{After\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{96}{134} * 100\%[/tex]
[tex]\%Percent = \frac{9600\%}{134}[/tex]
[tex]\%Percent = 72\%[/tex] --- approximated

19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?
Answer:
x ≤ 6
Step-by-step explanation:
Let the unknown number be x;
9 times the number is expressed as 9x
9 more than 9 times a number is expressed as 9x + 9
9 more than 9 times a number is less than or equal to 163 is then expressed as;
9x + 9≤ 63
≤ is the less than or equal to sign
Find the solution;
9x ≤ 63 - 9
9x≤54
x ≤ 54/9
x≤ 6
Hence the required solution is x ≤ 6
