Answer:
D
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying each radical
[tex]\sqrt{27}[/tex]
= [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]
[tex]\sqrt{12}[/tex]
= [tex]\sqrt{4(3)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]
[tex]\sqrt{48}[/tex]
= [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]
Then
3[tex]\sqrt{3}[/tex] - 2[tex]\sqrt{3}[/tex] + 4[tex]\sqrt{3}[/tex]
= 5[tex]\sqrt{3}[/tex] → D

In a shipment of 400 parts, 14 are found to be defective. How many parts out of 1000 would NOT be defective?
Can you please show a proportion I am confused.
Answer:
965 parts would not be defective.
Step-by-step explanation:
So for every 400 parts, 14 are defective. That means 386 are not defective. 1000 is 2.5 times as many as 400. So multiply 386 by 2.5 to get your answer.
386/1 * 5/2
193/1 * 5/1
965/1
That means for every 1000 parts, 965 would not be defective. The proportion(s) would be 386:400/965:1000 here.

\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} −x+4y=−9 y=−2x+6 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
Answer:
NO
Step-by-step explanation:
Given the system of equation
-x+4y = -9,... 1
y = -2x+6.... 2
To find the solution to the equation
Substitute equation 2 into 1
-x+4(-2x+6) = -9
-x-8x+24 = -9
-9x= -9-24
-9x = -33
x = 33/9
Find y
y = -2x+6
y = -2(33/9)+6
y = -66/9 + 6
y = -66+54/9
y = -12/9
y = -4/3
Hence (2,3) is not the solution to the system of equation
In the xy-plane, a line segment is dilated by a scale factor of 2. The dilation is centered at a
point not on the line segment. Select from the drop-down menus to make a true statement about the line segment and its image. The like segments are choose, and the length of the image is choose the length of the original line segment
The line segments are parallel and the length of the image is perpendicular to the length of the original line segment.
Why is the line segment by a scale factor. ?The line segment is a part of the line and is bounded by the two distinct endpoints. The line segment that represents the x, y plane is dilated by a factor of 2 and this dilation is centered around the point and not a line. Hence are line segment is parallel and perpendicular to the length of the original point shown in the image.

what is (5,1) reflected on the y axis
Answer:
(-5 , 1)
Step-by-step explanation:
If you are reflecting over the x-axis, you are changing the sign of the y.
If you are reflecting over the y-axis, you are changing the sign of the x.
In this case, you have the point (5 , 1). You are reflecting over the y-axis, which means that you are flipping the sign of the x value.
(5 , 1) reflected over the y-axis is (-5 , 1)
(-5 , 1)
~
Answer:
5 is how many units on the x axis (the horizontal one) and 1 is how many units on the y axis (the vertical one). So, the correct answer is 1.

0.75 (x + 16) = 3 – 0.5 (x-8)
Answer:
x= 18.29
Step-by-step explanation:
- distribute then simplify- .75x + 12 = 2.5x - 20
- subtract .75x from each side- 12 = 1.75x - 20
- add 20 on each side- 32 = 1.75x
- divide each side by 1.75x- x= 18.29

[tex]0.75\left(x+16\right)=3-0.5\left(x-8\right)[/tex]

What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
Yolanda jumped 4 3/4 feet = 19/4 feet
and, Jason jumped 6 2/3 feet in a jumping contest. = 20/3 feet
First take the LCM of 3 and 4
LCM( 3, 4) = 12
Then, Yolanda jumped = 19/4 x 3/3 = 57/ 12
and, Jason jumped = 20/3 x 4/4= 80/ 12
Hence, Jason jumped farther by (80/12 - 57/12)= 23/ 12 feet.

Find the value of each variable. Write answers in simplest radical form.
Answer:
The value of n is 6.
Step-by-step explanation:
Given that these 2 triangles form a square so we can assume that all sides are same. Then, we have to apply Pythagoras Theorem, a² + b² = c², where a, b are sides and c is hypotenuse :
n² + n² = (6√2)²
2n² = 6² × (√2)²
2n² = 72
n² = 72 ÷ 2
n² = 36
n = √36
n = 6

This week, 28% of customers ordered the fish entrée. If there were 900 customers this week, how many customers ordered the fish entrée?
Answer:
252 people
Step-by-step explanation:
There are two ways of solving.
you can use a proportion or an equation.
is=% as a decimal×of
or the proportion
[tex] \frac{is}{of} = \frac{\%}{100} [/tex]
step 1- Identity which is which.
28 is the percent and 900 is the of. we need to find the is.
step 2-
if you use an equation:
is=0.28x900
is=252
252 people ordered fish
you can also use a proportion
[tex] \frac{is}{of} = \frac{\%}{100} [/tex]
[tex] \frac{x}{900} = \frac{28}{100} [/tex]
x is a variable in place of is.
then, we cross cancel.
[tex]900 \times 28 = 100x[/tex]
25200=100x
x=252
The number of customers who ordered the fish entrée this week is 252.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, This week, 28% of customers ordered the fish entrée and there were 900 customers this week.
Let, 'x' be 28% of 900 customers.
Therefore,
28% of 900 is 'x' which is,
= (28/100)×900.
= 252 customers.
