Answer:
[tex](C)8x^4z^4\sqrt{2yz}[/tex]
Step-by-step explanation:
We want to determine an expression equivalent to: [tex]\sqrt{128x^8y^3z^9}[/tex]
[tex]\sqrt{ab} =\sqrt{a}*\sqrt{b}[/tex]
Therefore:
[tex]\sqrt{128x^8y^3z^9}=\sqrt{128}*\sqrt{x^8}*\sqrt{y^3}*\sqrt{z^9}[/tex]
[tex]=\sqrt{64*2}*\sqrt{x^{4*2}}*\sqrt{y^{2+1}}*\sqrt{z^{8+1}}\\=8\sqrt{2}*\sqrt{x^{4*2}}*\sqrt{y^2*y}*\sqrt{z^{8}*z}}[/tex]
[tex]=8\sqrt{2}*x^4*y \sqrt{y}*z^4\sqrt{z}\\=8*x^4*z^4*\sqrt{2}*\sqrt{y}*\sqrt{z}\\=8x^4z^4\sqrt{2yz}[/tex]

10x + 9y = -17
10x – 2y = 16
what is the solution
Answer:
x = 1 and y = -3
Step-by-step explanation:
Subtract eqn 1 from eqn 2
11y = - 33
y = -3
Substituting y into eqn 2...
10x - 2(-3) = 16
10x +6 = 16
10x = 10
x = 1
The solution to the system of equations 10x + 9y = -17 and 10x - 2y = 16 is x = 1 and y = -3. This solution was found using the elimination method, which involved manipulating the equations to eliminate one variable and then solving for the other.
Explanation:The question is related to the system of linear equations. A set of linear equations with the same variables is known as a system of equations. Here we have two equations; 10x + 9y = -17 and 10x - 2y = 16. The solution to this system of equations is the ordered pair (x, y) that satisfies both equations. We can find this by using the method of substitution or elimination.
Here's the solution using the elimination method:
First multiply the second equation by 9 and the first one by 2.You will get:So, the solution for the system of equations is x = 1 and y = -3.

Find the equation of the line described below. Write the equation in slope-intercept form, if possible, and graph the line. Contains (1,2) slope=3
Answer:
The equation of the line is y = 3x - 1
Step-by-step explanation:
In this question, we are asked to write the equation of the line using a point on the line and the slope of the line.
Mathematically, the slope-intercept form of a line can be written as;
y = mx + c
where m is the slope of the line and c is the y-intercept of the line. Now back to the question, we can see that we have all that is required for the line asides the value of the y-intercept C
To get this, we plug the values in the question into the equation of the straight line.
Here, we say y = 2, x = 1 and m = 3
2 = 3(1) + c
c = 2-3
c = -1
Thus, the equation of the line is y = 3x - 1
Write an equation that represents the line (-2,1) and (4,6)
Answer:
y - 6 = (5/6)(x - 4)
Step-by-step explanation:
Write an equation that represents the line through the points (-2,1) and (4,6)
As we move from (-2, 1) to (4, 6), x increases by 6 and y increases by 5.
Thus, the slope of the line connecting these two points is m = rise/run = 5/6.
Using (4, 6) as one point on the line, the equation of the line in point-slope form is
y - 6 = (5/6)(x - 4)
Answer: y - 6 = (5/6)(x - 4

Judith went shopping with $50 and spent $45. What percentage of her money did she spend
Answer:
90%
Step-by-step explanation:
Answer:
90%
Step-by-step explanation:
To determine what percentage of money she spent, you would divide the amount she spent by the total amount she had.
$45 ÷ $50 = 0.9
You would then multiply the decimal times 100 to convert the decimal to a percentage.
0.9 · 100 = 90
Tomas brought $32.00 to the art supply store. He bought a brush, a sketchbook, and a paint set. The brush was 1 4 as much as the sketchbook, and the sketchbook cost 2 3 the cost of the paint set. Tomas had $4.50 left over after buying these items.
Answer:
The price of the sketchbook is $10, the price of the brush is $2.5 and the price of the paint set is $15.
Step-by-step explanation:
Let the price of the brush be b.
Let the price of the sketchbook be s.
Let the price of the paint set be p.
The brush was 1/4 as much as the sketchbook. This means that:
b = 1/4 * s = s/4_______________(1)
The sketchbook was 2/3 the cost of the paint set. This means that:
s = 2/3 * p
=> p = 3s/2 __________________(2)
Initially, he had $32.00 and after buying all the items, he had $4.50 left with him. This means that:
b + s + p + 4.50 = 32.00 ___________(3)
Put (1) and (2) in (3):
=> s/4 + s + 3s/2 + 4.50 = 32.00
Collect like terms and simplify:
11s/4 = 32.00 - 4.50 = 27.5
=> s = (27.5 * 4) / 11
s = $10
Put this back in (1) and (2):
b = 10 / 4 = $2.5
and
p = (3 * 10) / 2 = $15
The price of the sketchbook is $10, the price of the brush is $2.5 and the price of the paint set is $15.

A total of 503 tickets were sold for the school play. They were either adult tickets or student tickets. There were 53 more student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
225 adult tickets were sold
To determine the number of adult tickets sold for the school play, we set up an equation with the variable representing adult tickets, and considered that there were 53 more student tickets sold than adult tickets. Solving the equation given the total number of tickets (503), we found that 225 adult tickets were sold.
The question is asking us to find out how many adult tickets were sold for the school play when given the total number of tickets and the information that there were 53 more student tickets sold than adult tickets. To do this, we'll let the number of adult tickets be represented by x and the number of student tickets be x + 53, as there were 53 more student tickets than adult tickets.
The total number of tickets sold is 503, which is the sum of adult tickets and student tickets. So, x (adult tickets) + (x + 53) (student tickets) = 503. Combining like terms, we get 2x + 53 = 503. Subtracting 53 from both sides, we have 2x = 450. Dividing both sides by 2 gives us x = 225. Therefore, 225 adult tickets were sold.

A software firm survey of 640 randomly selected adults showed that 99.2% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim.
Answer:
Given:
Sample size, n = 640
Since result showed that 99.2% of them would erase all of their personal information online if they could, we have:
P' = 99.2% = 0.992
Let's take p = 50%
Our null and alternative hypothesis will be :
H0 : u = 0.5
H1 : u > 0.5
In this case we are to check for the test statistic.
[tex] \frac{P' - p}{\sqrt{p(1-p)/n}} [/tex]
[tex] = \frac{0.992 - 50}{\sqrt{50(1-50)/640}} [/tex]
= 24.9
Test statistic, Z = 24.893
In conclusion, the results are significantly high, which suggets there is suffcient evidence to support the claim that most adults would erase all of their personal information online.

Katie bought 2 one-gallon bottles of juice for a party. Her guests drank 64gallons of juice. What fraction of a gallon of juice is left over? Draw a number line to show,and explain your answer.
Answer:
1/2 gallon
Step-by-step explanation:
Each full gallon can be represented as 4/4 of a gallon. Since Katie bought 2 one-gallon bottles, the total amount of juice is 8/4 gallons. The number line below represents the fraction of juice that her guests drank.
[tex]\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\\\ \frac{1}{4}\ \ \frac{2}{4}\ \ \frac{3}{4}\ \ \frac{4}{4}\ \ \frac{5}{4}\ \ \frac{6}{4}\ \ \frac{7}{4}\ \ \frac{8}{4}[/tex]
The fraction of a gallon of juice left over is:

Step by step
perimeter = 9 mi + 10 mi + 2 mi + 8 mi + 7 mi + 18 mi
perimeter = 44 mi
area = (2 × 10) + (7 × 18)
area = 20 + 126
area = 146 mi²
A movie theater has a seating capacity of 315. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults. There are half as many adults as there are children. If the total ticket sales was $ 2280, How many children, students, and adults attended?
Answer:
84 students
Step-by-step explanation:
Let x be the number of adults.
Then the number of children is 2x, according to the condition,
and the number of students is the rest (315-x-2x) = (315-3x).
The "money" equation (the revenue equation) is
12x + 5x(2x) + 7x(315-3x) = 2282.
12x + 10x + 7x315 - 21x = 2282
x = 2282 - 7x315 = 77 is the number of adults.
77 adults :2 x 77 = 154 children and the rest (315-77-154) = 84 students.
